What is an FX swap?
A foreign exchange (FX) swap is an agreement to exchange one currency for another on two settlement dates. The two parties buy and sell currencies at the pre-agreed rate twice: on the spot date and a date in the future. An FX swap allows a business to lock in a specific exchange rate to buy and sell a currency today, and then to buy and sell the same currency later, at the swap rate. The difference between the spot rate and the swap rate is determined by the difference in interest rates between the currencies being swapped.
FX swaps are often confused with currency swaps due to similar names, but these are distinct tools. An FX swap is a short-term agreement to exchange currencies at a spot rate and then on a later (maturity) date, without periodic interest payments. A currency swap is a long-term agreement, where parties exchange principal amounts and ongoing interest payments in different currencies.
Businesses of different sizes use FX swaps to help manage short-term liquidity and hedge immediate forex exposure. More complex currency swaps can help a multinational corporation with long-term financing in foreign markets and managing interest rate risks.
How does an FX swap work?
FX swaps contain a near leg and a far leg.
The near leg: The two parties exchange currencies at an agreed rate (usually the current spot rate). One receives currency A and pays currency B; the counterparty does the opposite. The near leg is the first transaction that settles on the near (or spot) value date, allowing the business to address immediate, short-term liquidity needs before the second (far) leg settles.
The far leg: On a date in the future, the two parties buy and sell the same currencies again, but not at that day’s spot rate. The swap rate is fixed in advance and calculated as the near-leg rate adjusted for the interest rate differential between the two currencies. This adjustment is called the swap points.
That makes an FX swap a funding tool rather than currency speculation. If currency A carries a higher interest rate than currency B, the party lending that currency is compensated through the far-leg exchange rate rather than a separate interest payment. The principle behind it is called interest rate parity (IRP). In other words, forward exchange rates should account for differences in interest rates so arbitrage opportunities don’t exist.
Convera, for example, creates an FX swap by simultaneously entering into a spot currency contract with a client to buy them a target currency in exchange for the swap settlement currency, and a forward contract to sell the target currency at the maturity date for the specified amount of swap settlement currency.
Walking through a simple FX swap example
Let’s say a US company needs 5 million EUR for three months to fund a European acquisition but holds its cash in USD. Rather than converting its dollars permanently, it can enter an FX swap with its bank or cross-border payments provider.
Near leg (today): Exchange US dollars for 5 million EUR at the spot rate of 1.08 USD/EUR, paying US$5.4 million.
Far leg (in three months): Exchange the euros back at a pre-agreed rate of 1.079 USD/EUR, reflecting the interest rate differential between the two currencies, receiving roughly $5.395 million.
The company gets the euros it needs immediately and already knows the terms of the return exchange. Even if EUR/USD moves over the next three months, the exchange rates for both legs have already been locked in.
Why do businesses use FX swaps?
Many businesses need a currency they don’t hold for a defined period, without disturbing their existing exposure. FX swaps can help manage this.
With predictable costs and a defined timeline, FX swaps show up across a wide range of business needs:
Short-term liquidity: Covering payroll, supplier payments, or working capital in a currency that doesn’t match your main cash holdings.
Rolling forward contracts: If a hedged payment date shifts, a swap extends the position to the new date without unwinding and re-establishing it.
Cash management across subsidiaries: Multinationals often centralize cash in one currency, then use swaps to fund operating entities elsewhere.
Bank and fund balance sheets: Financial institutions use FX swaps extensively to manage currency funding needs without altering longer-term currency positions.
Foreign currency optimization: where companies earn little or no interest on foreign currency deposits, FX swaps can provide a return where a currency with a high interest rate is swapped for a currency with a low interest rate. This interest rate difference can create a positive return.
FX swap vs. FX forward: What’s the difference?
A forward contract is a single agreement to exchange two currencies at a set rate on a future date. A swap is a spot deal plus a forward bundled together.
A one-time future payment — such as paying an overseas supplier in 90 days — is a task for a forward. But a present currency need that offsets at a later date calls for a swap since it prices both the access and the eventual reversal in one transaction.
FX swap vs. currency swap: What’s the difference?
An FX swap and a currency swap serve different purposes and operate on different timelines, despite their similar names. An FX swap is short-term — from overnight to about a year — and exchanges principal twice, with no interest payments in between.
A currency swap can often run for years and combines an exchange of principal with periodic interest payments over the life of the agreement; these typically occur in different currencies and sometimes different rate types (fixed versus floating). This financial tool is often used for longer-term financing, like funding a foreign subsidiary’s debt instead of closing a short-term gap.
Overall, FX swaps address near-term currency access. Currency swaps address longer-term currency and interest rate exposure together.

What are the risks of FX swaps?
FX swaps carry lower risk profiles than an open currency position, but they are still not risk-free. Here’s what to look out for.
Counterparty risk
Both legs are agreed today but settled at different times, so there’s a risk the counterparty doesn’t deliver on the far leg. This is the main risk a swap carries and the reason swaps are typically done with banks or regulated financial partners, such as Convera*.
Interest rate shifts
Swap points are set based on the rate differential at the time the deal is agreed. Unwinding early means repricing at whatever the market offers, which may be unfavorable.
Timing mismatches
If the far-leg date no longer lines up with an actual need — due to a delayed payment, for instance — the business may need to enter into a new swap, potentially adding cost.
Rollover risk
Businesses that use swaps repeatedly to fund ongoing operations face new swap points on every swap transaction, which can compound if differentials move against them.
Compared to leaving a position unhedged, these risks are small. The key is to use FX swaps as one tool within a broader hedging strategy, rather than treating them as risk-free instruments.

Is an FX swap right for your business?
FX swaps can be advantageous when a business has a near-term need for a currency it doesn’t hold and knows roughly when it no longer has the need. The more obvious use cases are funding overseas payroll, bridging a subsidiary’s working capital, or extending a forward whose date has moved.
They are less beneficial for long-term exposure, a situation where a currency swap or longer-dated forward works better. FX swaps may also be a poor fit for one-off payments with no reversal, where a plain forward is simpler.
The choice usually comes down to timeline, and needs: is it a temporary need or a permanent one? Most FX swaps fit into a wider FX hedging strategy alongside forwards and options, each chosen for how it lines up with the timing of the exposure. That’s the logic behind an effective hedging program.
*The availability of FX swaps varies by jurisdiction. Currently, Convera offers FX swaps in Australia, the EU (excluding Malta), Switzerland, the UK, and the USA.
