Definition
Arbitration of exchange is a commercial and financial technique for determining the most advantageous rate at which to settle a debt or obligation denominated in one currency by drawing a bill of exchange payable in another currency, where the transaction is routed through one or more intermediate financial centers rather than conducted as a direct two-currency exchange.
In practice, a merchant or banker owed a debt in one country could satisfy that obligation by issuing a bill of exchange drawn on a correspondent in a third country, with the exchange calculations flowing through that intermediate point. The "arbitration" in this context is a mathematical and commercial calculation — a comparison of available exchange rates across multiple routes — to identify the path that yields the most favorable effective rate of conversion. It is not arbitration in the modern sense of dispute resolution.

Common Language
Modern common usage (Wiktionary): The determination of the exchange rate between currencies when there are one or more intermediate places through which the operations must pass.
Historical common usage (Webster's 1913): Webster's 1913 defines "arbitration of exchange" as the act of determining the most advantageous course for drawing or remitting bills of exchange, considering the relative state of exchange between different places.
The word "arbitration" here derives from its older, broader sense of calculation or determination by judgment — closer to "arbitrage" than to the modern legal institution of binding dispute resolution. A researcher encountering this term in nineteenth-century commercial documents must resist importing any connotation of dispute, tribunal, or award. The term belongs to the vocabulary of merchant banking, not to the law of dispute resolution.

Common Confusion
ARBITRATION OF EXCHANGE vs. ARBITRATION (DISPUTE RESOLUTION): These terms share a word but belong to entirely different legal and commercial traditions. Modern arbitration is a private adjudicatory process for resolving disputes. Arbitration of exchange is a computational method for optimizing currency transactions through intermediate markets. Conflating the two in historical research will send a researcher to entirely the wrong body of sources.
ARBITRATION OF EXCHANGE vs. ARBITRAGE: These concepts are closely related and historically overlapping. Modern financial usage reserves "arbitrage" for the simultaneous purchase and sale of an asset across markets to profit from price discrepancies. Arbitration of exchange, as used in historical legal and commercial sources, describes the prior step: calculating which routing of a bill of exchange produces the best effective rate before executing the transaction. The distinction is often collapsed in older texts.

Why It Matters in Research
This term is primarily a historical artifact. Researchers will encounter it in nineteenth- and early twentieth-century commercial law treatises, merchant banking records, and cases involving disputes over bills of exchange, rather than in contemporary legal materials. Its practical context is the era of correspondent banking, when international payments moved through layered networks of bills rather than through electronic transfer.
Several research traps are worth flagging. First, full-text searches for "arbitration" in historical commercial law sources will surface this term alongside genuine dispute-resolution materials, requiring the researcher to distinguish context carefully. Second, Black's definition is sparse and assumes significant background knowledge of bills of exchange and the mechanics of foreign exchange markets; the definition makes no sense without that scaffolding. Third, the term appears in treatises on mercantile law and the law of bills of exchange rather than in treatises on arbitration as dispute resolution — researchers should consult the former shelf, not the latter.
The connection to bills of exchange is the essential navigational thread. Disputes that arose from miscalculations in arbitration of exchange — where a creditor alleged the debtor selected a disadvantageous route to inflate the effective cost of settlement — would appear in commercial court records under the law of bills of exchange, negotiable instruments, or merchant custom, not under headings related to arbitration.

Historical Dictionary Support
Black's Law Dictionary offers only a single sentence: "This takes place where a merchant pays his debts in one country by a bill of exchange upon another." This definition is accurate as far as it goes but strips away the computational and strategic dimension that gives the term its commercial meaning. It omits the central feature — that the exchange is routed through an intermediate place, and that the merchant's task is to calculate which intermediate route produces the best net result.
Wiktionary's definition is more informative on the mechanism, explicitly identifying the role of intermediate places. Neither source situates the term within the broader system of merchant banking or explains why this technique was necessary in the era before standardized international currency markets.
No significant divergence exists between the sources on the core meaning, but both definitions are incomplete for research purposes. The historical treatise literature on bills of exchange — particularly English and American works from the eighteenth and nineteenth centuries — provides the fuller operational context that dictionary definitions omit.

Jurisdictional Note
This term is not jurisdiction-specific in the modern sense; it reflects a practice of international merchant banking that operated across commercial centers including London, Amsterdam, Paris, and later New York. Legal disputes arising from the practice would have been adjudicated under the lex mercatoria as received into the common law of England and the United States, making English commercial court precedent the dominant source.
