If You Hold This 20 Year Treasury ETF You Are Losing Money Even With Yields Up

A 68-year-old retiree who moved $180,000 out of stocks and into the iShares 20+ Year Treasury Bond ETF (NASDAQ:TLT) in late 2024 was making a directional rate bet. The pitch was clean: lock in a 4.5% long-bond yield before the Federal Reserve cut rates, then collect price appreciation on top of monthly coupons. The 20-year Treasury yield instead climbed to 5%, and TLT’s price did what duration math says it must. Anyone still holding TLT for that original thesis needs to test the fund against its actual results.

What TLT is built to do

TLT holds a ladder of U.S. Treasury bonds with maturities of 20 years or more. The portfolio is entirely government paper, with the top 10 holdings making up roughly 44% of assets and a net expense ratio of 0.15%. The return engine has two parts: monthly coupon income passed through as distributions, and price changes driven almost entirely by movement in long-end Treasury yields. With a duration near 17 years, every 1 percentage point move in the 20-year yield translates into roughly a 17% move in TLT’s price, in the opposite direction.

That makes TLT less of a defensive holding and more of a leveraged directional bet on falling long rates.

The reality check

TLT trades near $85, essentially flat year to date at -0.05% and up only 3.5% over the past year despite a yield environment that should be paying holders well. Over five years the fund is down 28% and over ten 15%, before counting distributions.

For the retiree in the scenario, the duration math did exactly what it always does. With the 20-year yield rising from 4.5% to 5% over the holding period, the price leg fell roughly 8.5%, costing about $14,400 of principal. Monthly distributions, recently around $0.33 per share, added back roughly $7,000. Net result: a 4% loss on a position taken specifically to reduce risk.

Contrast that with US Treasury 3 Month Bill ETF (NASDAQ:TBIL), which carries near-zero duration and returned 4% over the same one-year window with no rate-driven drawdown. The simpler instrument paid more and lost nothing to price volatility.

The tradeoffs you actually inherit

1. Asymmetric duration risk. A 17-year duration cuts both ways, but with the 20-year yield in the 94th percentile of its 12-month range, holders are betting that 5% long rates fall meaningfully, not that they hold steady.
2. Income that does not bail you out. Distributions running near a 4.5% annual yield offset only about half of an 8% price decline. Coupons provide only a partial cushion.
3. Concentration in one macro variable. TLT is a single-factor exposure to long-end U.S. rates. There is no credit pickup, no equity diversification, no inflation linkage.

Who TLT actually fits

TLT belongs in a portfolio when an investor has a specific, defensible view that long rates will fall, or as a deliberate hedge against a deflationary recession. For a retiree seeking ballast against equity risk, a duration ladder built from TBIL, iShares 1-3 Year Treasury Bond ETF (NASDAQ:SHY), and iShares 3-7 Year Treasury Bond ETF (NASDAQ:IEI) captures most of the yield with a fraction of the rate sensitivity. SHY is up 2.9% over the past year and IEI 3%, with drawdowns a fraction of TLT’s. A practical guardrail for anyone still in TLT: a 10% stop from cost basis that forces a move down the curve before duration risk does more damage.
