Payment-versus-Payment Settlement

A foreign-exchange transaction requires two institutions to deliver different currencies to each other. Payment-versus-payment (PvP) is a settlement arrangement under which the final transfer of one currency occurs only if the corresponding final transfer of the other currency occurs, thereby controlling foreign-exchange settlement risk.

Risk being addressed

Currencies may be transferred through separate payment systems operating in different jurisdictions and time zones. Without coordination, one institution may make an irrevocable payment but fail to receive the currency owed because its counterparty defaults or the second payment is disrupted. This potential loss of the full amount delivered is called principal risk, also known as Herstatt risk.

How conditional settlement works

Participating institutions submit their payment instructions to a PvP arrangement, which matches or otherwise links the two currency legs. Settlement is completed only when both transfers can become final according to the arrangement's rules.

• If both currency legs satisfy the settlement conditions, the system executes them on an if-and-only-if basis.
• If either currency leg cannot settle, the corresponding transfer is withheld or reversed where the system design permits, preventing one-sided delivery.
• By making the two obligations interdependent, PvP removes the time gap in which one institution has paid while remaining exposed for the entire currency purchased.

Risk reduction and limitations

Properly designed PvP settlement can eliminate principal loss at settlement and reduce the possibility that one participant's failure transmits losses through the financial system. It does not eliminate every risk associated with the underlying foreign-exchange trade.

• A failed transaction may still create replacement-cost risk if exchange rates change before a substitute trade is arranged.
• Participants may face liquidity risk because both currencies must be available within the required settlement window.
• Operational failures, legal uncertainty concerning settlement finality, and funding disruptions can still delay or prevent settlement.
