The formula is: (1 + r2)^T2 = (1 + r1)^T1 ร— (1 + f)^(T2-T1), where r1 and r2 are spot rates for periods T1 and T2. A spot rate is the yield for immediate investment to maturity. The yield curve plots spot rates at different maturities.

What Are Forward Rates?

Forward rates are the market's implied future interest rates โ€” extracted from today's yield curve. If the 1-year spot rate is 5.0% and the 2-year spot is 5.25%, the implied 1-year rate starting 1 year from now is 5.50%. An inverted yield curve (2yr > 10yr) has predicted every US recession since 1970. Bond traders use forward rates to identify arbitrage opportunities and forecast Fed policy.

Forward Rate Formula

The implied forward rate f between times T1 and T2 is derived from spot rates r1 and r2:

(1 + r2)^T2 = (1 + r1)^T1 ร— (1 + f)^(T2-T1) โ†’ f = [(1+r2)^T2 / (1+r1)^T1]^(1/(T2-T1)) - 1

Forward Rate vs Spot Rate

Spot rates are yields for immediate investment to maturity. Forward rates are implied future rates. A steep yield curve (long rates > short rates) implies rising forward rates. An inverted curve implies falling forward rates and often signals recession expectations.

Forward Rate Agreements (FRAs)

FRAs are OTC derivatives where parties agree to exchange interest payments based on a reference rate (e.g., SOFR) for a future period. The implied forward rate from the yield curve is used to price FRAs. Banks and corporations use FRAs to hedge interest rate risk.

Yield Curve and Forward Rates

The slope of the yield curve determines forward rates. When the 2-year Treasury yields more than the 10-year, the curve is inverted โ€” historically a recession predictor. Forward rates extract the market's expectation of future short-term rates from the curve.

Implied Forward Rate and Arbitrage

In an arbitrage-free market, investing for 2 years at the 2-year spot rate must equal investing for 1 year and reinvesting at the 1-year forward rate. Any deviation would allow risk-free profit. This no-arbitrage condition defines the implied forward rate.

Fed Policy and Forward Rates

When short-term rates exceed long-term rates (inverted curve), forward rates fall โ€” the market expects the Fed to cut rates. Steep curves imply the market expects rate hikes. Traders use forward rate curves to gauge Fed policy expectations.

Applications in Bond Pricing

Forward rates are used to value bonds, price interest rate derivatives, and construct zero-coupon bond curves. Fixed-income portfolio managers use them to identify mispriced securities and to implement duration and convexity strategies.

International Forward Rates

EUR, GBP, and other sovereign yield curves have their own implied forward rates. Comparing US vs EUR forward curves reveals market expectations for Fed vs ECB policy divergence. Currency forwards are related but use interest rate parity.

Key Takeaways

  • Forward rates = implied future interest rates from the yield curve
  • Formula: (1+r2)^T2 = (1+r1)^T1 ร— (1+f)^(T2-T1)
  • Inverted curve (2yr > 10yr) has predicted US recessions since 1970
  • FRAs use forward rates for hedging and speculation
  • Steep curve โ†’ rising forward rates; inverted โ†’ falling forward rates
