How Does a Money Exchange Business Work? Key Facts to Know

A money exchange business facilitates the conversion of one currency into another, serving travelers, businesses, and investors. These businesses operate in physical locations like airports and tourist areas, as well as online platforms offering digital transactions.

While exchanging money might seem straightforward, these businesses must navigate financial regulations, operational challenges, and market fluctuations to remain profitable and compliant.

Licensing and Regulation

Operating a money exchange business requires compliance with financial regulations that vary by jurisdiction. In the United States, these businesses are classified as Money Services Businesses (MSBs) and must register with the Financial Crimes Enforcement Network (FinCEN) under the Bank Secrecy Act. Registration involves submitting FinCEN Form 107 and renewing it every two years. Additionally, state-level licensing is required, with each state imposing its own requirements. California mandates a minimum net worth of $250,000 for currency exchangers, while New York requires a surety bond of at least $500,000.

Businesses must also comply with anti-money laundering (AML) and counter-terrorist financing (CTF) laws. The USA PATRIOT Act requires MSBs to implement a written AML program, appoint a compliance officer, conduct employee training, and undergo independent audits. Noncompliance can result in fines of up to $250,000 per violation and potential criminal charges. Similar regulations exist internationally, such as the European Union’s Fifth Anti-Money Laundering Directive, which imposes strict customer due diligence requirements.

Regulators also require transaction reporting. In the U.S., businesses must file Currency Transaction Reports for cash transactions exceeding $10,000 and Suspicious Activity Reports for transactions that appear illicit. Failure to report can lead to enforcement actions, including fines and license revocation.

Exchange Rate Methods

Determining exchange rates is central to profitability. Businesses derive their rates from wholesale interbank rates, which fluctuate based on central bank policies, inflation, economic indicators, and geopolitical events. Instead of offering customers the raw interbank rate, businesses apply a markup.

Some use a fixed spread, adding a set percentage to the interbank rate to maintain consistent margins. Others implement a dynamic spread, adjusting the markup based on market volatility. During high fluctuations, businesses may widen spreads to mitigate risk, while in stable conditions, narrower spreads attract more customers.

Some providers offer tiered pricing, giving better rates for larger transactions. A customer exchanging $10,000 may receive a more favorable rate than someone exchanging $100, as businesses can afford lower margins on high-value transactions. This approach is common for corporate clients and high-net-worth individuals.

Operating Models

Money exchange businesses operate under different models, affecting costs, liquidity management, and customer acquisition. Some focus on physical locations, others emphasize digital transactions, and some use hybrid approaches.

Brick-and-mortar exchanges, commonly found in financial districts and shopping centers, rely on cash inventory to fulfill transactions. Managing liquidity is essential to prevent shortages or excessive cash holdings. These businesses establish relationships with wholesale currency suppliers or financial institutions to replenish and offload surplus currency. Some also engage in proprietary trading, speculating on short-term exchange rate movements to increase profits, though this carries financial risk.

Online platforms use electronic payment networks and banking partnerships to facilitate transactions without physical cash. These businesses hedge against currency risk using instruments such as forward contracts or options to lock in favorable rates. They also implement strict Know Your Customer protocols, as digital transactions are more susceptible to fraud. Many online providers integrate with payment processors like SWIFT or SEPA for faster cross-border transfers.

Hybrid models combine physical and digital services, allowing customers to book exchanges online and pick up cash in person. This appeals to travelers who want to secure exchange rates in advance while maintaining access to immediate cash. Some businesses offer prepaid foreign currency cards, letting users load funds at locked exchange rates to avoid currency fluctuations. These cards often include transaction fees and reload charges, adding another revenue stream.

Margins and Revenue

Profitability depends on pricing strategies, transaction volume, and operational efficiency. Revenue primarily comes from the spread between buy and sell rates, but additional income sources such as service fees, wire transfer charges, and wholesale currency trading can improve margins. Businesses serving corporate clients or high-net-worth individuals often negotiate custom rates, generating higher per-transaction revenue while maintaining competitive pricing for retail customers.

Managing float—the balance of foreign currencies held at any given time—affects profitability. Holding excess inventory of a weak or illiquid currency can lead to losses due to depreciation, while shortages force businesses to purchase at unfavorable rates. Forecasting based on historical transaction data and macroeconomic indicators helps mitigate these risks. Some firms use algorithmic pricing models that adjust rates dynamically based on inventory levels and market conditions.

Security Measures

Handling large volumes of cash and digital transactions exposes businesses to fraud, theft, and cyberattacks. Physical locations use surveillance cameras, alarm systems, and secure cash storage solutions such as time-delay safes. Many businesses also require dual authorization for high-value transactions to prevent fraud.

For online platforms, cybersecurity is essential. Encryption protocols such as TLS protect customer data, while multi-factor authentication is often required for account logins and transaction approvals. Regular penetration testing and vulnerability assessments help identify weaknesses before they can be exploited. Compliance with data protection laws such as the General Data Protection Regulation in the EU or the California Consumer Privacy Act is also necessary, as failure to secure customer information can result in fines and reputational damage.

Tax Accounting

Tax obligations vary based on jurisdiction, corporate structure, and revenue sources. In the U.S., currency exchange profits are subject to federal and state corporate income tax, with rates starting at 21% federally and additional state-specific rates. Businesses structured as pass-through entities, such as LLCs or S corporations, report earnings on the owners’ personal tax returns and may qualify for the Qualified Business Income deduction.

Foreign exchange gains and losses must be accurately reported. Under U.S. Generally Accepted Accounting Principles, unrealized foreign exchange gains are recorded as part of other comprehensive income until realized, while International Financial Reporting Standards require immediate recognition in profit or loss. Businesses engaged in speculative currency trading may face different tax treatments, with short-term gains taxed at ordinary income rates and long-term gains benefiting from lower capital gains tax rates. Proper classification of income streams is necessary to avoid misreporting, which can trigger IRS audits and penalties.

Recordkeeping

Accurate financial records ensure compliance with tax laws, regulatory reporting, and internal financial management. Businesses must retain transaction records, customer identification documents, and financial statements for specified periods, typically five years under U.S. federal regulations. Failure to maintain proper records can result in fines, license revocation, or legal action from regulators.

Accounting software tailored for foreign exchange businesses automates transaction tracking, reconciliation, and reporting. Many firms integrate their systems with enterprise resource planning solutions to centralize financial data and improve audit readiness. Regular internal audits help identify discrepancies and ensure compliance with financial reporting standards. Businesses operating internationally must also consider currency translation adjustments under U.S. GAAP or IFRS to accurately reflect financial performance in consolidated statements.
