Deep dive

How to think about TIPS (Treasury Inflation-Protected Securities)

TIPS pay fixed coupon rates but on inflation-adjusted principal. In deflation, principal is floored at original par. Real yield (yield after inflation) is known at purchase if held to maturity. TIPS are ideal for inflation protection but can underperform nominal Treasuries if inflation stays low.

Example: 10-year TIPS with 2% coupon, $1,000 par. Year 1 inflation: 3%. New principal = $1,030. Coupon payment = 2% × $1,030 = $20.60. Principal continues adjusting with inflation, ensuring real return of ~2% regardless of inflation path.
