Implied Interest Rate Divergence

Divergence

Implied interest rate divergence refers to the discrepancy between the interest rate derived from the pricing of financial derivatives and the prevailing interest rates in spot lending markets. In options trading, the implied interest rate is a key input in models like Black-Scholes, representing the market’s expectation of future funding costs. When this implied rate significantly deviates from the actual borrowing or lending rates available on platforms like Aave or Compound, it signals a potential market inefficiency. This divergence often arises from differences in risk perception, liquidity premiums, or structural inefficiencies between the derivatives and spot markets.
