01

Agreement and delivery are different stages

An FX transaction can involve an agreed price and obligations to deliver different currencies. Execution and settlement are therefore distinct parts of the process. The risks that arise after agreement should not be confused with the risk that the market price moves before a trade is placed.

02

What principal risk means

In deliverable FX, one party can pay away the currency it owes without receiving the currency due in return. That exposure to the value transferred is principal risk. A small expected trading gain can coexist with a much larger amount moving through the settlement process.

03

What payment versus payment changes

Payment-versus-payment arrangements make final delivery of one currency conditional on delivery of the other. This addresses a specific settlement exposure. It does not make a transaction free of every operational, liquidity, market or legal risk, and availability depends on the arrangements involved.

04

Netting answers a related question

Netting can reduce the payments or obligations that need to be exchanged under the relevant agreement. Its effect depends on how the arrangement works. It should not be treated as a synonym for payment versus payment: reducing an amount and making two deliveries conditional are different mechanisms.

05

Why infrastructure belongs in market reading

A complete description of a market includes the processes that support transactions, not just the chart. Settlement conventions, counterparties and payment arrangements affect what it means to complete a trade. Educational price examples intentionally leave much of this infrastructure out; recognising the omission makes the example more useful.

HYPOTHETICAL / A THOUGHT EXPERIMENT

A small gain and a large delivery

Imagine a transaction with a small expected price gain but obligations to exchange two large currency amounts. If one delivery occurs without the other, the exposure is not limited to that expected gain. This is why settlement risk is a different question from whether the original market view was correct.

A QUICK CHECK

Does reducing two currency obligations through netting automatically provide payment-versus-payment protection?

Keep the language clear Three useful definitions

Settlement — The completion of the payment or delivery obligations created by a transaction. Agreeing a price and settling the trade are different events. Read more ↗

Netting — Combining offsetting obligations under applicable arrangements. Reducing the amount to transfer does not by itself make the two currency transfers conditional on each other. Read more ↗

Payment versus payment — An arrangement linking the final transfer of one currency to the final transfer of the other, to reduce principal settlement risk. Read more ↗
