Question 9741Question →

A ruler forces citizens to obey state laws through the threat of imprisonment and physical sanctions rather than relying on constitutional right or public consent. Which form of power is being demonstrated in this scenario?

Coercive power

Legal-rational authority

Traditional power

Charismatic power

Show answer & explanation

Answer: Coercive power

Answer

Coercive power is the form of political power that relies on physical force, punishment, or threats to enforce compliance.

Coercive power is defined as the ability to compel obedience from others through force, sanctions, or the threat of punishment. Because the ruler relies on imprisonment and physical sanctions to enforce compliance, this represents coercive power.

Step-by-Step Solution

Analyze the means of enforcement in the stem

The ruler uses physical sanctions and threats of imprisonment rather than legal legitimacy or personal appeal.

Identifying the mechanism used to obtain compliance reveals the specific category of power.

Map the mechanism to standard political science forms of power

The application of force or intimidation corresponds directly to coercive power.

Power based on punishment or force is defined as coercive power.

Which of the following activities forms a primary distinguishing function of a merchant bank compared to a commercial bank in the financial system?

Operating cheque accounts and accepting small retail demand deposits from the general public

Issuing legal tender notes and acting as the official lender of last resort to financial institutions

Underwriting corporate security issues and providing acceptance facilities for bills of exchange

Granting short-term retail overdrafts to small-scale sole proprietorship enterprises for daily operations

Show answer & explanation

Answer: Underwriting corporate security issues and providing acceptance facilities for bills of exchange

Answer

Underwriting corporate security issues and providing acceptance facilities for bills of exchange

Underwriting corporate security issues and accepting bills of exchange are core wholesale investment banking functions that distinguish merchant banks from commercial retail banks.

Step-by-Step Solution

Differentiate between retail banking (commercial) and wholesale banking (merchant).

Commercial banks deal directly with the general public, providing retail services like savings/cheque accounts and short-term retail loans.

Merchant banks are prohibited from accepting small retail demand deposits.

Identify the primary functions unique to merchant banking.

Merchant banks focus on corporate clients by engaging in underwriting shares and debentures, bill acceptance, equipment leasing, and project finance.

These wholesale investment banking functions differentiate merchant banks from standard commercial banks.

Question 9743Question →

A firm facing a downward-sloping demand curve sells $12$ units of an item at a price of $\text{₦}75$ per unit. In order to sell $13$ units, it must lower the price of all units to $\text{₦}71$ . Calculate the Marginal Revenue of the $13\text{th}$ unit in Naira ( $\text{₦}$ ).

Show answer & explanation

Answer: 23

Answer

The Marginal Revenue of the 13th unit is ₦23.

Marginal Revenue (MR) measures the change in Total Revenue (TR) when output increases by one unit. Selling 12 units at ₦75 gives TR₁ = ₦900. Selling 13 units at ₦71 gives TR₂ = ₦923. The difference, ₦923 - ₦900 = ₦23, is the additional revenue generated by the 13th unit.

Step-by-Step Solution

Calculate the initial Total Revenue (TR₁) before expanding output

TR₁ = 12 units × ₦75 = ₦900

Total Revenue is calculated as Price multiplied by Quantity (TR = P × Q).

Calculate the new Total Revenue (TR₂) after expanding output to 13 units

TR₂ = 13 units × ₦71 = ₦923

When output increases to 13 units, the lower price of ₦71 applies to all units sold.

Determine the Marginal Revenue (MR) of the 13th unit

MR = TR₂ - TR₁ = ₦923 - ₦900 = ₦23

Marginal Revenue is the change in Total Revenue resulting from selling one additional unit of output (MR = ΔTR / ΔQ).

Question 9744Question →

An economic analyst comparing the standard of living between two nations observes that Country M reports a significantly lower Real Gross Domestic Product (GDP) per capita than Country N. However, a detailed socio-economic survey reveals that citizens in Country M enjoy higher life expectancy, lower stress levels, and consume a vast quantity of unrecorded home-grown agricultural produce and informal family care services. Which of the following best explains why the national income estimates fail to accurately reflect the comparative economic welfare of these two countries?

National income accounting excludes non-marketed household production and informal economic activities, leading to an underestimation of actual welfare in less monetized economies.

Changes in real national income directly reflect structural economic development rather than quantitative expansion in aggregate output.

National income calculations fail to convert nominal domestic figures into gross national product by adding net factor income earned abroad.

The output method of national income accounting inherently double counts intermediate agricultural goods in rural economies.

Show answer & explanation

Answer: National income accounting excludes non-marketed household production and informal economic activities, leading to an underestimation of actual welfare in less monetized economies.

Answer

National income accounting excludes non-marketed household production and informal economic activities, leading to an underestimation of actual welfare in less monetized economies.

National income data measure economic performance primarily through market transactions where goods and services are exchanged for money. In developing or rural-based economies, a significant portion of total production consists of non-monetized activities such as subsistence agriculture, home construction, and informal domestic labor. Because these activities do not enter formal markets, they are excluded from official GDP calculations, causing GDP per capita to significantly understate the actual material welfare and living standards of the population.

Step-by-Step Solution

Identify the primary economic gap presented in the scenario.

Country M has low measured real GDP per capita but high unrecorded subsistence production and favorable quality-of-life indicators.

The discrepancy highlights a specific technical limitation in how national income estimates measure total social welfare.

Evaluate the accounting rules regarding non-monetized transactions.

Transactions without a market price (such as home production, subsistence agriculture, and unbilled personal services) are excluded from official national income compilation.

National income statistics record only market transactions, causing economies with large informal or subsistence sectors to appear poorer than they actually are.

Select the option that correctly captures this structural limitation of national income data.

The statement identifying the exclusion of non-marketed household production and informal activities provides the accurate explanation.

It directly accounts for why measured GDP per capita understates total economic welfare in less monetized economies.

Question 9745Question →

Which type of public debt is incurred to finance non-revenue-yielding activities, such as military expenditure or emergency relief, leaving behind no physical asset to yield income for its repayment?

Deadweight debt

Productive debt

Funded debt

Internal debt

Show answer & explanation

Answer: Deadweight debt

Answer

Deadweight debt

Deadweight debt is public debt contracted to finance expenditures that yield no direct economic or financial return, such as wars or administrative emergencies, requiring future tax revenue for debt servicing.

Step-by-Step Solution

Analyze the expenditure purpose described in the question stem.

The funds are spent on non-revenue-yielding activities such as war or emergency relief.

Public debt is categorized based on whether the investment yields financial returns to cover debt servicing costs.

Match the expenditure characteristics to the correct public debt classification.

Debt incurred for non-asset creating consumption is classified as deadweight debt.

Since no revenue-generating asset is created, the burden of servicing deadweight debt falls entirely on future tax revenues.

Question 9746Question →

A government levies an income tax where an earner with a monthly income of $\text{N}400,000$ pays $\text{N}60,000$ , while an earner with a monthly income of $\text{N}800,000$ pays $\text{N}120,000$ . Which system of taxation is being applied?

Proportional tax system

Progressive tax system

Regressive tax system

Specific tax system

Show answer & explanation

Answer: Proportional tax system

Answer

Proportional tax system

A proportional tax system imposes a constant tax rate across all income levels. Here, the first earner pays

\frac{60,000}{400,000} \times 100\% = 15\%

and the second earner pays

\frac{120,000}{800,000} \times 100\% = 15\%

. Because the proportion of income taken in tax remains identical regardless of income size, the system is proportional.

Step-by-Step Solution

Calculate the effective tax rate for the first earner

Tax rate =

\frac{60,000}{400,000} \times 100\% = 15\%

To determine the tax system, we must evaluate the ratio of tax paid to total income.

Calculate the effective tax rate for the second earner

Tax rate =

\frac{120,000}{800,000} \times 100\% = 15\%

Comparing the tax rates between different income earners shows how the burden changes with income.

Classify the tax system based on the calculated tax rates

Both earners pay exactly

15\%

of their income in tax, indicating a proportional tax system.

A system where the tax rate remains constant regardless of income size is defined as proportional.

Answer

Allocative Efficiency matches with 'Achieved when price equals marginal cost (

P = MC

)'; Productive Efficiency matches with 'Achieved when output is produced at the minimum point of average total cost (

P = \text{min } ATC

)'; Excess Capacity matches with 'Operates to the left of the minimum average cost output level in long-run equilibrium'; Monopoly Deadweight Loss matches with 'Loss of consumer and producer surplus caused by restricting output below the competitive level'.

Each concept correctly maps to its defined economic criterion: Allocative efficiency is defined by

P = MC

, productive efficiency by

P = \text{min } ATC

, excess capacity by producing below minimum

ATC

capacity, and deadweight loss by the loss of welfare due to monopoly restriction.

Step-by-Step Solution

Identify the criteria for economic efficiency.

Allocative efficiency requires

P = MC

so consumer valuation matches cost of production. Productive efficiency requires producing at minimum average total cost (

P = \text{min } ATC

These are standard efficiency benchmarks in market structure comparison.

Identify non-competitive market outcomes.

Monopolistic competition results in excess capacity as firms produce below minimum

Question 9748Question →

A government experiencing a persistent fiscal deficit decides to curtail its capital expenditure on vital infrastructure projects while simultaneously increasing recurrent expenditure to fund administrative overheads. Which of the following is the most likely long-term economic consequence of this budgetary control measure?

A reduction in the economy's productive capacity and long-term economic growth

An immediate surge in private sector investment and industrial productivity

An automatic decrease in the national debt stock and general price level

A permanent elimination of structural budget deficits in subsequent fiscal years

Show answer & explanation

Answer: A reduction in the economy's productive capacity and long-term economic growth

Answer

A reduction in the economy's productive capacity and long-term economic growth

Capital expenditure directly contributes to physical capital formation (e.g., transport networks, energy facilities, and public utilities). When a government cuts capital spending to maintain high recurrent administrative expenses, long-term productive capacity decreases, leading to slower economic growth.

Step-by-Step Solution

Classify government spending components

Capital expenditure creates long-term physical assets and infrastructure, whereas recurrent expenditure pays for ongoing operational costs such as wages and overheads.

Evaluating the long-term impact of fiscal policy requires distinguishing wealth-creating capital projects from consumable recurrent expenses.

Analyze the impact of prioritizing recurrent consumption over capital investment

Diverting financial resources away from roads, power plants, and public works directly weakens national infrastructure and lowers potential Gross Domestic Product (GDP).

Question 9749Question →

Which of the following theoretical reasons explains why standard indifference curves can never intersect each other?

Intersection violates the assumption of transitivity by implying that two distinct levels of total satisfaction yield equal utility.

Intersection causes the marginal rate of substitution between goods to remain constant along both curves.

Intersection forces total utility to reach its maximum point where marginal utility becomes zero.

Intersection implies that the consumer is unwilling to substitute one good for another at any point on the curves.

Show answer & explanation

Answer: Intersection violates the assumption of transitivity by implying that two distinct levels of total satisfaction yield equal utility.

Answer

Intersection violates the assumption of transitivity by implying that two distinct levels of total satisfaction yield equal utility.

Indifference curves cannot intersect because if they did, the point of intersection would belong to two different utility levels. By transitivity, all points on both curves would yield the exact same utility, which contradicts the concept that higher or distinct curves represent different satisfaction levels.

Step-by-Step Solution

Identify the core property being evaluated.

The property is the non-intersection of indifference curves.

Indifference curves represent combinations of two goods that give a consumer equal satisfaction.

Question 9750Question →

Unlike internal debt which involves a redistribution of purchasing power within a country, servicing external public debt imposes a real economic burden on the debtor nation. How does the repayment of interest and principal on external debt directly affect the domestic economy?

It requires an outflow of real goods and services, reducing the Gross National Product available for domestic consumption

It expands the domestic Gross Domestic Product because government expenditure rises to process foreign debt payments

It causes direct monetary expansion as domestic commercial banks create credit to compensate for the debt servicing costs

It generates a persistent surplus on the current account of the balance of payments through foreign capital inflows

Show answer & explanation

Answer: It requires an outflow of real goods and services, reducing the Gross National Product available for domestic consumption

Answer

Servicing external public debt requires an outflow of real goods and services, reducing the Gross National Product available for domestic consumption.

Servicing external debt requires the borrowing country to surrender foreign exchange and real economic output to foreign creditors. This net transfer of resources abroad reduces the country's Gross National Product (GNP) and leaves fewer goods and services available for domestic consumption and investment.

Step-by-Step Solution

Distinguish between internal and external debt burden mechanisms

Internal debt servicing transfers money between domestic taxpayers and domestic bondholders without altering total national wealth, whereas external debt servicing transfers wealth out of the nation.

Understanding the direction of resource flows is critical for public debt analysis.

Analyze the foreign exchange and macroeconomic impact of external debt service

To pay foreign creditors, the debtor nation must export more goods and services than it imports (surplus of real exports), transferring domestic production to foreigners.

Foreign debt obligations must be settled in foreign currencies earned through real resource exports.

Identify the net effect on national income aggregates

The outflow of income to foreign debt holders reduces Gross National Product (GNP) relative to Gross Domestic Product (GDP), lowering total domestic living standards.

GNP measures income earned by residents, deducting factor payments made to foreign creditors.

Question 9751Question →

In evaluating the comparative performance of economic systems, which of the following best explains why a pure market economy is less effective at achieving social equity than a command economy?

Resource allocation in a market economy is determined by consumer purchasing power rather than societal needs.

Central planning boards in market economies fix prices below equilibrium, causing chronic market shortages.

The state retains exclusive ownership of all capital assets, suppressing private initiative and market competition.

The price mechanism automatically eliminates negative externalities by internalizing all production costs.

Show answer & explanation

Answer: Resource allocation in a market economy is determined by consumer purchasing power rather than societal needs.

Answer

Resource allocation in a market economy is determined by consumer purchasing power rather than societal needs.

In a free market economy, the price mechanism allocates resources based on effective demand—meaning consumer purchasing power dictates what is produced. Because wealth and income are naturally distributed unevenly under private ownership, market economies struggle with social equity compared to command economies where the state distributes goods based on administrative assessments of societal welfare.

Step-by-Step Solution

Analyze how resources are allocated in a market economy versus a command economy.

In a market economy, the price mechanism responds to effective demand (ability and willingness to pay). In a command economy, state planners direct resources based on socio-economic priorities.

Understanding the fundamental allocation driver for each system is key to evaluating equity outcomes.

Evaluate the equity implications of market-based resource allocation.

Because income distribution is unequal in free markets, resource allocation favors wealthy consumers while basic needs of lower-income households may go unmet.

This structural feature explains why pure market systems exhibit lower social equity compared to planned systems.

Match each public debt management strategy or concept on the left with its corresponding operational description on the right.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Debt Conversion matches with exchanging high-yield short-term debt instruments for low-interest long-term debt securities; Sinking Fund matches with accumulating regular budgetary appropriations into a specialized account dedicated to retiring maturing bonds; Debt Repudiation matches with unilaterally declaring public debt null and void; Debt Refinancing matches with replacing existing high-interest obligations with a new lower-rate loan.

Each public debt management term is paired with its precise economic operation: Debt Conversion refers to altering bond terms via instrument exchange; Sinking Fund is the systematic reserve creation for debt payoff; Debt Repudiation is the explicit rejection of sovereign obligations; and Debt Refinancing is taking out new loans at cheaper rates to repay older liabilities.

Step-by-Step Solution

Analyze Debt Conversion

Identify that conversion refers to altering the terms of existing debt by swapping existing securities for new ones with lower interest rates or longer maturities.

Differentiating conversion from simple refinancing requires recognizing the structural exchange of debt instruments.

Analyze Sinking Fund

Identify that a sinking fund is a systematic redemption method involving amortized annual allocations reserved for future debt payoff.

This sets aside current revenue streams into a dedicated accumulation account to prevent sudden fiscal strain upon maturity.

Analyze Debt Repudiation

Identify repudiation as an illegal or extreme sovereign refusal to acknowledge or pay back national liabilities.

Unlike debt restructuring or forgiveness, repudiation is a unilateral break of contractual obligations.

Analyze Debt Refinancing

Identify refinancing as securing a fresh loan under lower interest conditions specifically to liquidate an active, higher-cost debt.

Refinancing replaces an old loan contract with a new borrowing contract.

bankers' acceptance placement managed by a discount house.

Show answer & explanation

Answer: rights issue managed by an issuing house.

Answer

A rights issue managed by an issuing house.

When a public limited company raises long-term funds by granting existing shareholders the pre-emptive right to purchase additional new shares in proportion to their holdings, it conducts a rights issue. Issuing houses are the specialized capital market institutions that structure, underwrite, and manage such primary market securities offerings.

Step-by-Step Solution

Analyze the financial objective and time horizon.

The corporate expansion requires long-term capital, placing the transaction in the capital market rather than the money market.

Capital markets deal with long-term securities (maturity > 1 year), whereas money markets deal with short-term instruments.

Identify the specific equity issuance method described.

Offering new shares specifically to current shareholders in proportion to their ownership is known as a rights issue.

Rights issues preserve relative ownership percentages and raise fresh equity capital in the primary capital market.

Determine the appropriate institutional intermediary.

New capital market securities are underwritten and brought to the primary market by issuing houses.

Question 9754Question →

In a domestic agricultural market, the weekly demand function for palm oil is given by $Q_d = 800 - 20P$ and the supply function is given by $Q_s = -100 + 10P$ , where $P$ is the price per litre in Naira and $Q$ is the quantity in litres. What is the equilibrium quantity in litres?

Show answer & explanation

Answer: 200

Answer

The equilibrium quantity is 200 litres.

Market equilibrium occurs where quantity demanded equals quantity supplied (

Q_d = Q_s

). Setting

800 - 20P = -100 + 10P

yields

30P = 900

, which gives an equilibrium price of

P = 30

Naira. Substituting

P = 30

into the demand function

Q_d = 800 - 20(30)

gives an equilibrium quantity of

200

litres.

Step-by-Step Solution

Equate the demand function

Q_d

and the supply function

Q_s

to find the market equilibrium condition.

800 - 20P = -100 + 10P

At market equilibrium, quantity demanded equals quantity supplied.

Rearrange the equation to isolate

P

and calculate the equilibrium price.

30P = 900 \implies P = 30

Adding

20P

and

100

to both sides groups variable terms and constant terms together.

Substitute the equilibrium price (

P = 30

) into the demand equation to determine the equilibrium quantity.

Q^* = 800 - 20(30) = 200

Evaluating

Q_d

P = 30

gives the total quantity traded at equilibrium.

Question 9755Question →

Two sovereign nations report identical figures for Real Gross Domestic Product (GDP) per capita. However, the majority of citizens in Country A enjoy noticeably higher welfare and living standards than those in Country B. Which of the following economic factors best accounts for this limitation in using national income data to compare living standards?

Country A experienced a surge in general price levels, which expanded the nominal value of national output.

Country A included the value of both raw agricultural inputs and final food products in its national product calculation.

Country A has a more equitable distribution of income, ensuring national wealth is widely shared among the population.

Country A achieved a higher annual rate of GDP growth, which automatically guarantees greater economic development.

Show answer & explanation

Answer: Country A has a more equitable distribution of income, ensuring national wealth is widely shared among the population.

Answer

Country A has a more equitable distribution of income, ensuring national wealth is widely shared among the population.

Per capita national income is an aggregate average that does not reveal how income is distributed across households. If two countries have the same real GDP per capita, the nation with a more equal distribution of income will experience higher widespread living standards and lower poverty levels compared to a nation where income is highly concentrated.

Step-by-Step Solution

Analyze the limitation of per capita income metrics.

Recognize that per capita income is calculated as Total National Income divided by Total Population, which represents a simple average.

Per capita figures conceal how national output is distributed among citizens.

Question 9758Question →

An economy comprises three interconnected firms operating within a single production year:

- Firm P extracts raw iron ore valued at $\$15\text{ million}$ . It sells $\$10\text{ million}$ worth of ore to Firm Q and exports the remaining $\$5\text{ million}$ directly to foreign buyers.
- Firm Q processes the $\$10\text{ million}$ ore to produce steel valued at $\$28\text{ million}$ . It sells $\$20\text{ million}$ worth of steel to Firm R and retains $\$8\text{ million}$ of steel as capital inventory additions.
- Firm R manufactures motor vehicles valued at $\$50\text{ million}$ , utilizing the $\$20\text{ million}$ steel purchased from Firm Q along with $\$5\text{ million}$ worth of imported engine components.

To avoid double counting and correctly account for intermediate inputs, what is the total contribution of these production activities to the nation's Gross Domestic Product (GDP)?

\$58\text{ million}

\$93\text{ million}

\$63\text{ million}

\$50\text{ million}

Show answer & explanation

Answer: $\$58\text{ million}$

Answer

The total contribution to Gross Domestic Product (GDP) is

\$58\text{ million}

The value-added method measures national output by taking the gross value of each firm's output and subtracting the cost of intermediate goods and services purchased from other suppliers (including foreign imports). Firm P generates

\$15\text{ million}

in value added. Firm Q produces

\$28\text{ million}

in total steel from

\$10\text{ million}

in ore inputs, generating

\$18\text{ million}

in value added. Firm R produces

\$50\text{ million}

in vehicles using

\$20\text{ million}

in domestic steel and

\$5\text{ million}

in imported parts, generating

\$25\text{ million}

in domestic value added. The sum of domestic value added is

\$15\text{m} + \$18\text{m} + \$25\text{m} = \$58\text{ million}

. Alternatively, summing final goods directly (exported ore

\$5\text{m}

+ steel inventory additions

\$8\text{m}

+ final vehicles

\$50\text{m}

minus imports

\$5\text{m}

) also yields

\$58\text{ million}

Step-by-Step Solution

Calculate the value added by Firm P

Value Added (P) = Total Output (

\$15\text{m}

) - Intermediate Inputs (

\$0\text{m}

) =

\$15\text{ million}

Firm P extracts raw ore without purchasing intermediate inputs from other domestic producers.

Calculate the value added by Firm Q

Value Added (Q) = Total Steel Output (

\$28\text{m}

) - Intermediate Ore Inputs (

\$10\text{m}

) =

\$18\text{ million}

Firm Q uses

\$10\text{ million}

of iron ore as intermediate input to produce

\$28\text{ million}

worth of steel.

Calculate the value added by Firm R

Value Added (R) = Total Vehicle Output (

\$50\text{m}

) - Domestic Steel Input (

\$20\text{m}

) - Imported Engine Input (

\$5\text{m}

) =

\$25\text{ million}

Imports must be deducted alongside domestic intermediate goods because imported components are not part of domestic value added.

Sum the value added across all firms to find total GDP contribution

Total GDP = Value Added (P) + Value Added (Q) + Value Added (R) =

\$15\text{m} + \$18\text{m} + \$25\text{m} = \$58\text{ million}

The value-added approach ensures that every intermediate product is counted exactly once.

Match each market component or sector flow in the circular flow of income with its correct functional economic description.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Factor Market Flow corresponds to household supply of productive inputs in exchange for wages, rent, interest, and profit. Product Market Flow corresponds to firm sales of finished goods and services for consumer expenditure. Financial Market Flow corresponds to channeling household savings into business investment. Rest of the World Sector Flow corresponds to import leakage and export injection flows.

Each market and sector component performs a distinct function in maintaining the circular flow of income: the factor market exchanges productive services for income, the product market exchanges final goods for consumption expenditure, the financial market channels savings into investment, and the foreign sector handles imports and exports.

Step-by-Step Solution

Identify the primary exchange taking place in the factor market.

Households provide factor services (labor, land, capital, enterprise) to firms and receive factor incomes (wages, rent, interest, profits).

The factor market represents the upstream market where resources are bought and sold.

Identify the exchange taking place in the product market.

Firms sell output to households in exchange for spending on consumption.

The product market is where final outputs are exchanged for revenue.

Identify the role of the financial market in the circular flow.

Savings withdrawn by households are converted into investment spending by business firms.

Financial institutions act as intermediaries converting leakages into productive injections.

Identify how the foreign sector influences domestic circular flows.

Expenditure on imports represents a leakage from the domestic flow, whereas earnings from exports represent an injection.

Open economy flows involve foreign trade interactions.

Foreign reserves decrease while the domestic monetary base expands

Foreign reserves remain unchanged because the currency experiences official devaluation

Show answer & explanation

Answer: Foreign reserves decrease while the domestic monetary base contracts

Answer

Foreign reserves decrease while the domestic monetary base contracts.

To defend the domestic currency against depreciation under a managed float exchange rate system, the central bank sells foreign currencies out of its external reserves to meet excess market demand. In exchange for this foreign currency, commercial banks pay the central bank with domestic currency. Consequently, the central bank's foreign reserves decline, and the domestic money supply (monetary base) contracts as domestic currency is absorbed from circulation.

Step-by-Step Solution

Analyze the Central Bank intervention mechanics

To defend a depreciating currency under a managed float, the Central Bank sells foreign currency (e.g., US Dollars) from its external reserves into the foreign exchange market.

Selling foreign exchange increases the market supply of foreign currency relative to domestic currency, counteracting downward pressure on the exchange rate.

Determine the effect on foreign exchange reserves

Foreign reserves decline because the Central Bank depletes its stock of foreign currency assets during the intervention.

Foreign reserves consist of holdings of foreign currencies, so outright sales directly reduce reserve levels.

Determine the effect on domestic monetary base

The domestic monetary base contracts as domestic currency is paid by commercial banks to the central bank to purchase foreign currency.

The central bank withdraws domestic currency from private banking circulation when receiving payment for foreign exchange, reducing high-powered money unless sterilised.
