iShares 20+ Year Treasury ETF yields match mid-term corporates due to high term premium

TLTTLT

The iShares 20+ Year Treasury Bond ETF currently offers long-term yields on par with mid-term high-grade corporate bonds due to an elevated term premium. A modest increase in risk aversion could drive TLT gains as corporate spreads widen while investors seek its superior liquidity and low default risk.

1. Modest Rebound Following Treasury Selloff

The iShares 20+ Year Treasury Bond ETF (TLT) rose by 0.5% on Wednesday after sliding 1% in the prior session. This rebound came as the U.S. Treasury market stabilized around a 10-year yield of 4.27%, following sharp volatility earlier in the week. Traders cited President Trump’s public calls for lower interest rates as a background factor but noted that long-duration bonds had largely priced in expectations of continued accommodative policy from the Federal Reserve. Total trading volume in TLT was 5.8 million shares, 20% above its 30-day average, indicating heightened investor interest in duration exposure during the recent rate swings.

2. Attractive Term Premium and Relative Value Case

With the term premium on long-term U.S. Treasuries near multi-year highs, TLT now yields roughly in line with mid-term, high-grade corporate bonds—despite sovereign debt’s superior liquidity and negligible default risk. Analysts at Evergreen Capital estimate that the current term premium stands at approximately 1.5 percentage points, up from 0.9 at the start of the quarter. This spread suggests that even a small shift toward risk aversion could drive TLT higher while corporate bond prices underperform. Margin-adjusted inflows into TLT reached $420 million last week, the largest weekly amount since August, underscoring growing investor preference for government paper as economic uncertainties mount.
