Why do puttable bonds typically have lower yields than otherwise identical straight bonds?

Investors value the put option (right to sell back the bond at par on specific dates), so they accept a lower yield as compensation for receiving this right. The yield reduction equals the annualized option premium. Putable bonds protect against rising interest rates.

In what interest rate environments are putable bonds most valuable?

Putable bonds are most valuable when interest rates rise significantly above the coupon rate, as investors can put the bond at par and reinvest at higher rates. The put option becomes deep in-the-money, providing capital protection unavailable in straight bonds.
