Purchasing Power Risk and TIPS Suitability
An investor with moderate risk tolerance is deeply concerned that accelerating inflation will erode the purchasing power of her fixed income portfolio. Which security is specifically designed to eliminate purchasing power risk?
TIPS adjust their principal value semiannually based on changes in the Consumer Price Index (CPI), ensuring that both principal and interest payments keep pace with inflation.
Complete Analysis & Legal Rationale
Fixed-rate long-term debt (Treasuries, preferreds, zero-coupons) is heavily damaged by inflation because future fixed cash flows lose purchasing power. TIPS directly index the par value to the CPI, insulating the investor against inflation.
Distractor Autopsy (Why Other Options Are Traps)
FINRA exam writers design incorrect distractors using specific calculation mistakes and regulatory misconceptions. Review why each option succeeds or fails:
TIPS semiannually adjust principal to CPI, providing direct inflation hedging.
30-year fixed Treasuries have high duration and suffer major price declines during inflationary rate hikes.
Preferred stock behaves like perpetual fixed-income and loses value when inflation rises.
Zero-coupon bonds have the highest duration risk and zero inflation adjustment.
