TLT Falls 4.35% YTD While SGOV Gains 2.53%
Two iShares Treasury ETFs show opposite results due to duration differences. TLT loses value as yields rise, while SGOV gains through reinvestment.
The iShares 20+ Year Treasury Bond ETF (TLT) is down 4.35% year to date. The iShares 0-3 Month Treasury Bond ETF (SGOV) is up 2.53% over the same period. Both funds hold only U.S. Treasuries. The divergence stems from their position on the yield curve. TLT holds long-term bonds with high duration. SGOV holds short-term bills with near-zero duration.
TLT has an effective duration of approximately 16 to 17 years. SGOV has a duration close to 0.1 years. This structural difference dictates their response to interest rate changes. TLT acts as a leveraged bet on falling long-end yields. SGOV functions as a cash-equivalent instrument that reinvests at prevailing rates.
Duration Drives Price Sensitivity
A one percentage point rise in the 30-year yield reduces TLT’s price by roughly 16%. The 30-year Treasury yield currently sits at 5.37%. The 13-week T-bill yield is 3.91%. TLT holders collect higher coupons but face daily price declines. SGOV holders collect lower coupons but see stable principal values.
The 2022 rate shock highlighted this dynamic. TLT fell approximately 31% during that year. SGOV remained essentially flat on price. Its distributions increased alongside Federal Reserve rate hikes. The pattern continues in a smaller scale today. TLT is down 5.73% over the past year. SGOV is up 3.79% over the same period.
Income Versus Principal Performance
TLT paid $3.89 per share in distributions over the last 12 months. SGOV paid $3.71 per share over the same window. The distribution amounts are similar. The principal outcomes differ significantly. TLT’s share price slid from about $85.80 to $80.88. SGOV’s price drifted from about $96.84 to $100.51.
SGOV resets monthly toward par, preserving capital. TLT absorbs market volatility in its share price. SGOV carries a lower expense ratio of 0.09%. TLT has an expense ratio of 0.15%. The lower fee matters when returns rely on coupon income. The 10-year to 2-year spread stands at 0.39%. The curve has re-steepened only modestly.
Strategic Implications for Investors
SGOV serves as a cash-parking vehicle with minimal price risk. It earns the front-end Treasury rate. TLT is a tactical position based on a specific rate view. It requires a belief that the Federal Reserve will cut rates aggressively. Long yields must fall meaningfully from the current 5.37% level. The calculus changes if the yield curve inverts on recession fears.
Until the Fed signals a genuine easing cycle, TLT holders face continued price pressure. SGOV holders continue to collect yields without principal erosion. GN auto markets/bonds: treasury yields data confirms the current divergence. The choice between the two depends on the investor's view of future interest rates. Long duration has been a wealth destroyer since 2021.
