Also known as: TIPS (TIP) (ETF_TIP, TIPS) · 20Y+ Treasury ETF (long bonds, treasury ETF)
Why This Comparison Matters
TIP (iShares TIPS Bond ETF) holds Treasury Inflation-Protected Securities; TLT (iShares 20+ Year Treasury Bond ETF) holds nominal long Treasuries. The spread between them is the cleanest tradeable proxy for inflation expectations. As of April 24, 2026, the 10-year breakeven inflation rate sits at 2.38 percent, with nominal 10-year yields at 4.31 percent and 10-year real yields near 1.9 percent. TIP offers roughly 4.5 percent yield and has delivered 5.39 percent total return over the past year; TLT at $86.55 has struggled as its 17-year duration amplifies rate risk.
What TIPS Are and How They Work
Treasury Inflation-Protected Securities (TIPS) are US Treasury bonds whose principal adjusts with the Consumer Price Index (CPI-U, not seasonally adjusted). The coupon rate on a TIPS is fixed at auction, but the principal value rises with inflation and falls with deflation (subject to a floor at the original par value at maturity). Because the coupon is applied to the adjusted principal, interest payments also grow with inflation.
TIPS were first issued in January 1997. They trade in 5-year, 10-year, and 30-year maturities. As of early 2026, total TIPS outstanding is approximately $2.0 trillion, representing roughly 7 percent of marketable Treasury debt. TIP ETF holds 99.99 percent TIPS across the full maturity spectrum, with an expense ratio of 0.18 percent and a current distribution yield of approximately 4.5 percent. Duration is approximately 6-7 years.
TLT as the Pure Duration Alternative
TLT holds nominal US Treasury bonds with 20 or more years to maturity, making it the longest-duration mainstream Treasury ETF. Duration is approximately 17 to 18 years. Expense ratio is 0.15 percent. Distribution yield approximately 4.5 to 5 percent based on current Treasury yields.
TLT has no inflation adjustment. Its returns are driven entirely by nominal interest rate movements. If nominal rates rise 100 basis points, TLT falls approximately 17 percent. If rates fall 100 basis points, TLT rises approximately 17 percent. Combined with its fixed coupon, TLT is a pure bet on nominal rate direction, which makes it the cleanest Treasury hedge for deflationary or growth-scare scenarios where the Fed is expected to cut rates aggressively.
The Breakeven Inflation Concept
The difference between a nominal Treasury yield and a matched-maturity TIPS yield is called the breakeven inflation rate. It represents the average CPI inflation rate over the bond's life at which TIPS and nominal bonds would deliver equal total returns. As of April 2026, the 10-year nominal yields 4.31 percent and 10-year TIPS yield approximately 1.93 percent, giving a 10-year breakeven of approximately 2.38 percent.

Frequently Asked Questions
What are TIPS and how do they differ from regular Treasury bonds?+
TIPS (Treasury Inflation-Protected Securities) are US Treasury bonds whose principal value adjusts with the Consumer Price Index (CPI-U). When inflation rises, the principal rises, and the fixed coupon rate is applied to the higher principal, so interest payments also grow with inflation. Nominal Treasuries have fixed principal and coupon regardless of inflation, so they lose real value in high-inflation environments. TIPS protect real purchasing power; nominal Treasuries deliver a fixed nominal return that only beats inflation if actual inflation comes in below what was expected at purchase.
What is the 10-year breakeven inflation rate?+
The 10-year breakeven inflation rate is the difference between the 10-year nominal Treasury yield and the 10-year TIPS real yield. It represents the average CPI inflation rate over 10 years at which TIPS and nominal Treasuries would deliver equal returns. As of April 2026, the 10-year breakeven sits at 2.38 percent, slightly above the Fed's 2 percent target. It is the single most-watched market-based inflation expectation, and it moves in real time as nominal and TIPS yields change.
Why did TIPS lose money in 2022 despite high inflation?+
TIP fell approximately 12 percent in 2022 because real yields rose from -1.2 percent to +1.7 percent over the year, a nearly 3 percentage point move. For TIP's approximately 7-year duration, that produced a price loss of roughly 20 percent on the real-yield component. The CPI accrual offset some of the loss, leaving a net decline of about 12 percent. Inflation protection hedges the inflation component of TIPS returns but does not hedge the real-yield component. In aggressive Fed tightening cycles, rising real yields dominate, and TIPS lose money even while inflation is high.
