What Is TLT ETF? Price, Yield and How the Fund Works

The TLT ETF is the iShares 20+ Year Treasury Bond ETF, a fund that holds US government bonds with more than 20 years left until maturity. It tracks the ICE US Treasury 20+ Year Bond Index, charges an expense ratio of 0.15% a year and pays a monthly distribution. Its price moves in the opposite direction to long-term Treasury yields.

Think of TLT as one ticker that stands in for a very long ladder of Treasury bonds. A stock reflects a single company, while TLT reflects how the market prices the cost of lending to the US government for two to three decades. When investors expect inflation and interest rates to stay high, long bonds tend to lose value. When they expect rates to fall, the reverse can happen.

Key takeaways

• The TLT ETF is a passive exchange-traded fund managed by BlackRock under the iShares brand. It launched on 22 July 2002 and trades on NASDAQ.
• It held 47 US Treasury bonds on 23 October 2026, with a weighted average maturity of 26.03 years and an effective duration of 14.92 years.
• An effective duration of 14.92 years means a one percentage point rise in yields could reduce the fund’s price by roughly 15%, and a fall of the same size could lift it by a similar amount.
• The fund’s 30-day SEC yield was 5.33% and its 12-month trailing yield was 4.79% on 23 October 2026. Distributions are paid monthly and are not fixed.
• TLT has had a hard run since its 2020 peak. Its net asset value was USD 81.67 on 26 October 2026, against a 52-week range of USD 77.08 to USD 91.99.
• The fund is not guaranteed by the US government or insured by the FDIC, even though the bonds it holds are US government debt.

What is TLT ETF?

TLT is the ticker for the iShares 20+ Year Treasury Bond ETF, an exchange-traded fund that gives investors exposure to US Treasury bonds with remaining maturities greater than 20 years. An exchange-traded fund pools investor money into a basket of assets and trades on an exchange like a share, so buying one TLT share gives exposure to the whole basket in a single transaction.

The fund is passively managed. Rather than choosing bonds, it follows the ICE US Treasury 20+ Year Bond Index, so its holdings change only when the index changes. That keeps costs low: the expense ratio is 0.15%, which equals USD 15 a year for every USD 10,000 held.

TLT is a very large fund. Net assets were approximately USD 47.76 billion on 26 October 2026, spread over 584.9 million shares. The 30-day median bid/ask spread was 0.01% on 23 October 2026, which shows how easily the fund trades during market hours.

TLT at a glance

What does TLT hold?

The TLT ETF holds US Treasury bonds and nothing else. According to iShares, Treasuries made up 100.01% of the fund’s market value on 23 October 2026. There are no corporate bonds, no mortgage-backed securities and no foreign government debt.

Every bond in the portfolio has more than 20 years left until it matures. The average sits at 26.03 years, so the fund is exposed mainly to bonds issued as 30-year Treasuries and to older issues that still have more than two decades to run. As bonds age below 20 years of remaining life they leave the index at a rebalance, and newly issued long bonds come in.

The portfolio is small by the standards of an equity fund, with 47 holdings on 23 October 2026. That is normal for a Treasury fund. Each bond is a very large issue, so the index does not need hundreds of lines to represent the market. It also means TLT has almost no credit risk. The bonds are backed by the US government, and the fund’s main risk is not default but price movement as interest rates change.

The weighted average coupon was 3.36 on 23 October 2026. That is well below the fund’s 30-day SEC yield of 5.33%, which suggests many of the bonds were issued when interest rates were lower and now trade below their face value.

How does the TLT ETF work?

The TLT ETF works by owning a portfolio of long-dated Treasuries and passing on the interest they earn, less the fund’s costs, as a monthly distribution. The share price then rises and falls with the market value of those bonds. Two ideas explain most of what the fund does: the link between bond prices and yields, and duration.

Why bond prices move opposite to yields

A bond pays a fixed coupon. When market interest rates rise, newly issued bonds pay more, so existing bonds with lower coupons become less attractive and their prices fall. When market rates fall, the fixed coupons on existing bonds look better and their prices rise. A government bond is simply a loan to the state, and its price is whatever buyers will pay for that stream of fixed payments.

TLT inherits this relationship. Because it holds bonds that will not mature for two or three decades, there is a long stretch of fixed payments exposed to any change in the rate used to value them. That makes it one of the most rate-sensitive mainstream bond funds.

What duration tells you

Duration estimates how much a bond’s price is likely to move for a given change in yields. As a rough guide, a fund’s price changes by about 1% for every year of duration, in the opposite direction to yields. With an effective duration of 14.92 years on 23 October 2026, a one percentage point rise in long-term yields could reduce TLT’s price by around 15%, and a one percentage point fall could lift it by a similar amount.

The estimate is a simplification. iShares reported a convexity of 3.15 on the same date, which captures how the price response bends as yields move. In practice the gain from a fall in yields is slightly larger than the loss from an equal rise, but the first-order message holds: TLT magnifies changes in long-term rates.

Duration is not the same as maturity. Maturity is the date on which the bond repays its principal, while duration measures price sensitivity and takes into account the coupons received along the way. TLT’s average maturity is 26.03 years, but its duration is shorter at 14.92 years because the coupons return part of the investment before the bonds mature.

How the monthly distribution works

TLT pays out the interest earned on its bonds each month. The latest ex-dividend date in the fund’s records was 1 October 2026, with an income distribution of USD 0.311581 per share. The amount changes from month to month because it depends on the number of days in the month, the bonds held and the fund’s expenses.

Two yield figures are worth knowing:

• 30-day SEC yield: a standardised measure of the income the fund’s bonds are earning right now, after expenses. It was 5.33% on 23 October 2026.
• 12-month trailing yield: the income actually distributed over the past year, divided by the current price. It was 4.79% on 23 October 2026.

The two figures differ because the SEC yield looks at current bond yields, which have risen, while the trailing yield includes months when the portfolio earned less. Neither is a promise of future income. The distribution is investment income and does not protect the share price, so a fund can pay out monthly and still show a negative total return over the year.

TLT and the 20 year treasury bond yield

TLT and the 20 year treasury bond yield are two views of the same market. The 20 year yield is the rate the US government pays to borrow for 20 years, and TLT is a fund whose value depends on what that rate, and the rates around it, do. When the yield rises, TLT’s price tends to fall. When the yield falls, TLT’s price tends to rise.

The link is close but not identical. TLT holds bonds across the 20 to 30 year range, not just 20 year bonds, so it also responds to the 30 year yield and to the shape of the curve between them. Its distributions add to returns, so total return and price return differ. The fund also trades on an exchange, so its market price can move slightly away from its net asset value. On 23 October 2026 the premium to net asset value was 0.07%, which is small.

Reading a yield chart helps in following the fund. A guide to reading the 10-year Treasury yield chart covers the chart patterns that traders watch, and the same logic applies to the longer end of the curve. Yields tend to move on three things: expectations for central bank policy, expectations for inflation, and the amount of extra compensation, called the term premium, that investors ask for locking money up for a long time.

Why Treasury moves affect bond yields goes through how Treasury supply and demand feed into the yields that set TLT’s price. A rise in yields driven by stronger inflation expectations can hurt TLT, while a rise driven by strong growth can have a different effect on other markets. Context matters, so the same yield move does not always mean the same thing.

TLT price: how has the fund moved?

All prices and yields in this section and the rest of the article were captured in October 2026. The TLT ETF’s price has fallen sharply since 2020 and the fund has had one of the weakest decades in its history. The Daily Upside reported in August 2026 that TLT dropped below USD 82 a share, its lowest level in 22 years, and that it was more than 50% below its 2020 high of USD 171.11. iShares recorded a net asset value of USD 81.67 on 26 October 2026, with a 52-week range of USD 77.08 to USD 91.99.

The reasons for the decline, as reported by The Daily Upside, include four years of rising long-term yields, heavy demand for capital to fund AI infrastructure, higher inflation expectations linked to the war in Iran, and investors becoming more cautious about holding long-dated government debt. Bloomberg Intelligence analyst Athanasios Psarofagis said some of the fund’s best years might be behind it. That is one analyst’s view, not a forecast, and the fund can move either way as yields change.

TLT returns over different periods

Source: iShares. Past performance is not an indication of future results.

The index returns are slightly higher than the fund returns in every period, and the gap of around 0.1% a year is close to the 0.15% expense ratio. That is what a low-cost tracker is expected to show.

Calendar-year returns show how uneven the path has been. According to iShares, the fund’s total returns from 2021 to 2025 were -4.76%, -31.41%, 2.96%, -7.84% and 4.17%. The 2022 figure, a fall of more than 31% in a year, is the one that surprised many investors who expected Treasuries to hold their value. That year long-term yields rose sharply, and TLT’s duration turned a bond market move into an equity-sized loss.

What affects the price of the TLT ETF?

TLT’s price responds to anything that changes expectations for long-term interest rates. Five drivers account for most of its moves.

None of these works in isolation. A fall in growth expectations can pull yields down, while a jump in inflation can push them up in the same week. This is why TLT has at times moved with equities and at other times against them, and why its role in a portfolio is debated.

Traders who follow interest rates closely often compare TLT with other markets that react to the same inputs. US Treasury yields and gold are linked through real rates, for example, and a guide on how to trade interest rate expectations explains how rate expectations feed into several asset classes at once.

TLT vs other bond ETFs and leveraged versions

TLT sits at the long end of the Treasury market, and other funds cover different maturities or use leverage. Comparing them shows what TLT is and what it is not.

The Daily Upside noted in August 2026 that BIL had outperformed TLT over two, three and five years and year to date, according to Bloomberg Intelligence. That shows how a fund with almost no duration can do better than a long-bond fund when yields rise.

Leveraged and inverse funds such as TMF and TBT are a different category. They aim to deliver a multiple of the daily move, and because they reset every day, their returns over longer periods can differ sharply from the multiple of the underlying index. A guide on how a leveraged ETF such as TQQQ works explains the daily reset and volatility decay in detail, and the same mechanics apply to leveraged bond funds.

Advantages and disadvantages of the TLT ETF

The TLT ETF offers focused, low-cost exposure to long US Treasuries, and the same focus produces its main risk.

Is the TLT ETF a good investment?

Whether TLT suits a particular investor depends on that investor’s goals, time horizon and view on interest rates, so there is no single answer. The arguments on each side are well known.

Supporters point to the starting yield. A 30-day SEC yield of 5.33% is high by the standards of the past 15 years, and if inflation cools and yields fall, long bonds could rise in price. They also note that long Treasuries have tended to rally in deep slowdowns.

Critics point to the record. A five-year annualised return of -8.44% and a ten-year return of -2.78% show that holding long bonds has been costly in an era of rising yields. They add that a shorter-dated fund can earn a similar income with far less price risk, and that long bonds did not protect portfolios in 2022, when stocks and bonds fell together.

Both views can be correct at different times, which is why TLT is usually described as a tool for a specific purpose, not a default holding.

Who may find the TLT ETF relevant?

The TLT ETF tends to attract three kinds of market participant:

• Investors with a view on long-term rates. Because the fund moves sharply with yields, it is a direct way to express a view that long yields will fall or rise, for example by holding it, or by taking the opposite position through derivatives.
• Portfolio builders seeking diversification. Long Treasuries have often offset equity weakness during growth scares. The link is not constant, so the hedge can fail, as it did in 2022.
• Income-focused holders. The monthly distribution appeals to people who want regular payouts, though the share price can erase the income.

It is less likely to suit people who need stable capital over the next few years, who cannot tolerate double-digit price swings, or who want predictable income. Anyone unsure should speak to an independent financial adviser.

How to gain exposure to long-term Treasury moves

There are two broad ways to take a position on long-term US interest rates: buy the ETF, or trade a derivative that tracks bond prices. Each has different mechanics and risks. A general process looks like this.

Step 1: Define what you want exposure to

Decide whether the aim is to hold long Treasuries over years, to speculate on the direction of yields over days or weeks, or to hedge an existing portfolio. The right instrument depends on the answer, and so does the amount of risk involved.

Step 2: Choose between the fund and a derivative

Owning TLT means buying shares through a securities broker and holding the fund, with all of its price movement and its distributions. A contract for difference (CFD) works differently: it lets a trader speculate on the price movement of an asset without owning it, and the trader can go long or short.

Step 3: Check which instruments a provider actually offers

Not every provider lists every fund, so it is worth checking before opening a position. VT Markets has added TLT to its newly launched ETF and share CFDs, so a trader can speculate on the fund’s price movement without owning the shares, and can go long or short. VT’s ETF range also includes bond funds such as AGG and BNDX, and its bond CFDs cover contracts including the US 10 YR T-Note, Euro-Bund and UK Long Gilt futures. A US 10-year note has a shorter maturity and a lower duration than TLT, so it will not behave in the same way as a 20+ year fund. A guide to trading US Treasury CFDs explains how Treasury exposure through CFDs differs from owning bonds or funds.

Step 4: Choose a regulated provider

Check that the provider is authorised by a financial regulator in the jurisdiction that applies to you, and read its terms on fees, margin and overnight financing.

Step 5: Plan risk before opening a position

Bond markets can move quickly on inflation data or central bank decisions. Decide in advance how much capital is at risk, where a position would be closed if it moves against you, and how leverage will affect the result. Leverage magnifies losses as well as gains, and in CFD trading losses can exceed the initial deposit.

Step 6: Keep following the data

TLT responds to inflation reports, central bank meetings, Treasury auctions and shifts in growth expectations. A calendar of these events helps in understanding why long-term yields move on a given day.

Tips for following TLT

• Watch yields before price. TLT follows long-term Treasury yields, so the yield on 20 and 30 year bonds usually explains the day’s move.
• Read duration, not just maturity. Duration tells you how sharply the price could respond. It changes over time as yields and the portfolio change.
• Separate price return from total return. The monthly distribution can hide a falling share price. Compare total return figures with the price chart.
• Use more than one yield measure. The SEC yield shows current income, while the trailing yield shows what was paid.
• Check the fund’s own data. The iShares fund page publishes holdings, duration and yield on a regular basis, and those figures are more reliable than third-party summaries.
• Treat forecasts with caution. Forecasts for TLT depend on forecasts for inflation and central bank policy, and both have a poor record over long horizons.

Conclusion

TLT is a low-cost, passive fund that gives concentrated exposure to US Treasury bonds with more than 20 years to maturity. Its price moves opposite to long-term yields, and with an effective duration of 14.92 years the moves can be large. A 30-day SEC yield of 5.33% and a monthly distribution give the TLT ETF an income profile, but returns over the past five and ten years show how much price risk comes with it.

Understanding the link between the ETF TLT, duration and the 20 year treasury bond yield is the foundation for using or analysing the fund. The same understanding applies to any instrument that tracks long-dated government bonds, including bond CFDs.

TLT frequently asked questions (FAQs)

What does TLT stand for?

TLT is the ticker symbol of the iShares 20+ Year Treasury Bond ETF. It is generally read as shorthand for long-term Treasuries. The fund holds US government bonds with more than 20 years left until maturity and tracks the ICE US Treasury 20+ Year Bond Index.

Does the TLT ETF pay a dividend?

TLT pays a monthly distribution made up of the interest earned on its bonds, less fund expenses. The most recent distribution in the fund’s records had an ex-date of 1 October 2026 and was USD 0.311581 per share. The amount varies from month to month, and the distribution does not protect the share price from falling.

Why does TLT fall when yields rise?

TLT holds bonds that pay fixed coupons. When market yields rise, newly issued bonds pay more, so older bonds with lower coupons are worth less. Because TLT’s bonds have an average maturity of 26.03 years and an effective duration of 14.92 years, the fall in price can be large when yields move up.

How is the TLT ETF different from buying a Treasury bond directly?

A Treasury bond held to maturity repays its face value on a set date, so the investor knows the payments in advance. TLT never matures. It keeps replacing bonds as they age below 20 years, so its price keeps moving with yields and there is no date on which the principal is returned. In return, the fund offers diversification across many bonds, daily trading and a monthly distribution.

Is the TLT ETF the same as the 20 year Treasury yield?

No. The 20 year Treasury yield is an interest rate, while TLT is a fund whose price depends on that rate and on the yields of other long bonds. When the yield rises, TLT’s price tends to fall, and when it falls, the price tends to rise. TLT also pays distributions and holds bonds up to 30 years, so the two do not move in a perfectly mirrored way.
