Investors are betting that interest rates will rise faster than expected by purchasing put options on interest rates. The put to call ratio on interest rate options has risen from 1.9 to 3.2, indicating that more investors now expect rates to increase sooner as employment figures rise and the Federal Reserve continues to phase out its bond purchasing stimulus program and raise rates. Traders are using short-term interest rate options to profit from any potential policy changes or surprises from the Federal Reserve regarding interest rates.
