Passage:
In late fourteenth-century Florence, merchant banking dynasties began employing double-entry bookkeeping alongside conditional credit instruments known as *cambium* contracts. Traditional historiography holds that these contracts were introduced primarily to evade papal prohibitions against usury—the charging of interest on loans—by masking interest payments within foreign currency exchange rate differentials. However, recent archival analysis of ledger entries from the Datini merchant enterprise suggests a more nuanced commercial imperative.

While *cambium* transactions did indeed obscure interest, their primary operational advantage lay in mitigating settlement risk across distant European trading hubs. Because international shipments faced unpredictable maritime delays and currency fluctuations, medieval merchants required a mechanism that combined credit extension with currency conversion at predetermined exchange rates. The Datini ledgers reveal that even in domestic transactions where church oversight was minimal and usury enforcement was rarely pursued by municipal magistrates, merchants consistently chose multi-currency credit contracts over simple interest-bearing promissory notes. Furthermore, non-performing *cambium* contracts were routinely restructured using secondary exchange rates, demonstrating that merchants treated the exchange differential not merely as a fixed penalty or hidden fee, but as a dynamic risk-hedging mechanism tied to seasonal market liquidity.

Which of the following can be most logically inferred from the passage regarding merchant practices in late fourteenth-century Florence?
