Foreign Exchange Rate Integrity®

FX Pre-Agreed Spread Agreements

A written spread over the interbank mid-market rate moves your FX cost out of the bank's discretion and into an agreement you can check.

Why it matters

Your bank is a counterparty, not an adviser.

Banks do not act in a fiduciary or advisory capacity in the foreign exchange market. They are not required to put the client's interest first; they deal as counterparties aiming to maximize their own profitability. Most retain broad discretion over pricing and markups, citing transaction size, currency pair, market volatility and liquidity. Because those factors are loosely defined, the bank effectively reserves the right to set the spread as it sees fit, often without disclosing how it decides or what it expects to earn.

Many banks also do not reveal the components of the all-in rate, and many apply "last look," a final check that lets them reprice or reject a trade if the market moves. A pre-agreed spread limits that discretion. It establishes consistent, upfront pricing and gives you predictability and fairness where transparency would otherwise be missing.

The fine print

What banks reserve in their FX disclosures

  • Principal, not agent

    The bank deals for its own account, at arm's length, and does not act as your agent, fiduciary or financial adviser.

  • No best execution

    Unless agreed in writing, the bank does not commit to giving you the best available price.

  • Its own interests

    As a market maker, the bank manages its own risk and positions, which can conflict with yours, including the price it quotes you.

  • Consent by dealing

    Continuing to trade with the bank can be treated as agreeing to its disclosure terms.
