FX Forward Rate
Covered Interest Rate Parity (CIRP) states that the FX forward rate must equal: F(d/f) = S(d/f) × e^((r_d − r_f)×T). If this did not hold, investors could borrow in the low-rate currency, invest in the high-rate currency, and lock in the exchange rate with a forward to earn risk-free profits. CIRP ensures no such arbitrage exists. Forward points = (F − S) × 10,000 pips. A positive interest rate differential (r_d > r_f) means the domestic currency trades at a forward premium.
