Cross-Currency Swap Pricer

Understand cross-currency swaps and use BlueGamma's pricer to calculate implied spreads across currencies and tenors.

What Is a Cross-Currency Swap?

A cross-currency swap (XCCY swap) is a derivative contract where two parties exchange principal and interest payments in different currencies. Unlike a standard interest rate swap (same currency on both legs), a cross-currency swap involves:

• Initial exchange of principal at the spot FX rate

• Periodic interest payments in each respective currency

• Final re-exchange of principal at the original spot rate (not the prevailing rate at maturity)

Structure of a cross-currency swap: principal exchanged at start and maturity, with periodic interest payments in each currency

How Cross-Currency Swaps Work

Example: EUR/USD Cross-Currency Swap

Imagine a European company that has issued USD-denominated bonds but earns revenue in EUR. They want to hedge their FX exposure.

At Inception
Company receives	$100 million (from bond investors)
Company pays	€90 million (to swap counterparty at spot rate of 1.11)

During the Swap
Company pays	EUR floating rate (e.g., EURIBOR) on €90m notional
Company receives	USD floating rate (e.g., SOFR) on $100m notional

At Maturity
Company pays	$100 million (to swap counterparty)
Company receives	€90 million (from swap counterparty)

The company has effectively converted their USD debt into EUR debt, matching their revenue currency.

The Cross-Currency Basis

The cross-currency basis is the spread added to one leg of a cross-currency swap to make it fair value. It reflects:

• Supply and demand for funding in each currency

• Credit and counterparty risk differences

• Regulatory and balance sheet constraints on banks

A negative EUR/USD basis (common historically) means EUR borrowers pay a premium to swap into USD — reflecting higher demand for USD funding.

💡 Why it matters: The basis can add or reduce 20-50+ bps to your effective funding cost, making it critical for pricing cross-currency debt.

Step 2: Select Your Currencies

Use the dropdowns at the top:

Field	Description
Base Currency	The currency you're funding in (e.g., EUR)
Quote Currency	The currency you're swapping into (e.g., USD)

Supported pairs: EUR/USD, GBP/USD, EUR/GBP

Step 3: Choose Your Tenors

The pricing matrix lets you compare multiple tenors side by side:

• Click + Add Tenor to add individual tenors (e.g., 7Y, 10Y, 12Y, 15Y)

• Click All to add all available tenors

• Click Clear to remove all and start fresh

• Click × next to any tenor to remove it

---

Step 4: Enter Your Spread

For each tenor, enter your Input: Spread (bps) — the spread over the base currency benchmark.

The matrix automatically displays:

Row	Description
EUR Benchmark (%)	The benchmark swap rate for the base currency
Input: Spread (bps)	Your input spread over the benchmark
EUR Coupon (%)	The all-in coupon (benchmark + spread)
USD Coupon (%)	The equivalent coupon in the quote currency
USD Benchmark (bps)	The benchmark spread for the quote currency
Output: Implied Spread	The implied spread in USD based on your input
Spread Delta (bps)	Difference between input and implied spread

---

Step 5: Analyse the Results

Spread vs Tenor Analysis: see how the basis affects pricing at different maturities

The Spread vs Tenor Analysis chart shows:

• Differential (green bars): The spread delta at each tenor

• EUR (dark blue line): Your input spread across tenors

• USD (light blue line): The implied USD spread

---

Step 6: View Historical Spreads

Historical analysis: is the current basis attractive vs recent history?

The Historical USD Implied Spread section shows how implied spreads have moved over time. Configure:

• Base and Quote Currency

• Tenor (e.g., 10 years)

• EUR Spread to Benchmark (bps)
