How Does the Interest Rate Environment Affect the Decision to Early Exercise a Put Option?

Higher interest rates make it more attractive to early exercise an American put option. By exercising the put, the holder receives the strike price cash immediately, which can then be invested to earn the higher risk-free rate.

This benefit of earning interest outweighs the loss of the remaining time value, making early exercise more likely when rates are high.
