TMF Basics - 3x Leverage on Long-Term Treasuries

TMF (Direxion Daily 20+ Year Treasury Bull 3X Shares) targets 3x the daily return of the ICE U.S. Treasury 20+ Year Bond Index. Launched April 16, 2009 by Direxion. Expense ratio 1.01%. Duration of ~16-18 years means a 1% rate change moves the index ~16-18%. TMF amplifies this to ~48-54%.

Net assets shrank from ~$3 billion peak (2021) to ~$1 billion (2025) after the devastating 2022-2023 rate-hiking cycle drove massive investor exits.

TMF fundamentally differs from equity leveraged ETFs. Stocks tend upward long-term; bond prices depend on rate cycles with no guaranteed long-term direction. This makes TMF investment decisions more complex.

TMF is a directional bet on interest rates. Getting the direction wrong produces catastrophic losses, as 2022-2023 demonstrated.

Interest Rates and Bond Prices - Duration Times 3x

Basic principle: rates up means bond prices down, and vice versa. The degree is measured by duration. 20+ year treasuries have ~16-18 year duration, meaning 1% rate increase causes ~16-18% price decline.

TMF triples this: effective duration ~48-54 years. A 1% rate increase causes ~48-54% TMF decline. In 2022, the Fed raised rates from 0.25% to 4.50% (+4.25%), and long-term rates rose ~2.5%.

A 2.5% long-rate increase means ~-40% for the 20+ year index. TMF theoretically: -120% (exceeding total loss), but daily rebalancing limited actual decline to ~-75%. The safety valve worked.

Conversely, when rates fall, TMF explodes upward. In early 2020, long rates dropped ~1.5% and TMF gained ~+60%. The explosive power during rate cuts rivals equity leveraged ETFs.

2022-2023 Devastation - Fed Rate Hikes

2022 was TMF's worst year ever. The Fed raised rates 4.25% to combat 40-year-high inflation. The 10-year yield surged from 1.5% to 3.9%, the 20+ year index fell -31%, and TMF lost -73%.

2023 continued the pain as the 10-year briefly hit 5.0% in October. From its 2021 high to October 2023 low, TMF fell over -85%. Recovering from -85% requires +567%, equivalent to long rates falling ~3%.

Most TMF holders had bet that rates would quickly fall. But inflation proved stickier than expected and the Fed hiked far beyond market forecasts. With high-leverage products, being wrong on direction is fatal.

The lesson: TMF is a directional bet on rates. Unlike equity leveraged ETFs that benefit from stocks' long-term upward bias, TMF has no such structural tailwind. Reading the rate cycle correctly is TMF's lifeline.

Stock Crash Hedge - March 2020 Performance

TMF's main appeal is hedging stock crashes. Stocks and long-term treasuries historically show negative correlation: when stocks crash, flight-to-quality drives bond prices up. The 2020 COVID crash demonstrated this perfectly.

From February 19 to March 9, 2020, as S&P 500 fell -19%, TMF gained over +40%. The Fed's emergency rate cuts drove the 10-year from 1.6% to 0.5%. While TQQQ plunged -50%+, TMF rose +40%, proving its hedge value.

However, after March 9, the picture changed. With rates already near zero, TMF's upside was limited. From March 9-23, stocks fell further but TMF also declined. The hedge stopped working when rates hit the zero bound.

TMF's hedge works best when rates are sufficiently high (providing room to fall). At 2025's rate levels (4-5%), there is ample room for TMF to function as a crash hedge in the next equity downturn.

TQQQ + TMF Combination Strategy

The TQQQ + TMF portfolio (known as HFEA: Hedgefundie's Excellent Adventure) typically allocates 55% TQQQ + 45% TMF, rebalancing quarterly. The theory: stocks and bonds' negative correlation provides diversification even at 3x leverage.

Backtests (2010-2021) showed +30%+ annual returns with maximum drawdown around -40%, far exceeding S&P 500 alone. But 2022 destroyed this strategy.

2022 saw stocks and bonds fall simultaneously, a rare event in 40 years. Inflation-fighting rate hikes crushed bonds while rate-driven valuation compression crushed stocks. TQQQ -79% and TMF -73% occurred together, producing -75%+ portfolio loss.

When stock-bond negative correlation breaks down, this strategy fails catastrophically. It works only in environments where stocks and bonds move inversely.

Explosive Power During Rate Cuts

TMF's true value emerges during rate-cutting cycles. In 2019, three Fed cuts produced +67% TMF annual return. In early 2020, a 1.4% drop in long rates delivered ~+80% in just two months.

If the Fed enters a cutting cycle from 5%+ to 3%, long rates could fall 1-2%, potentially delivering +100%+ TMF returns. But the pace and magnitude of cuts remain uncertain.

When simulating TMF with compound interest tools, consider both rate direction and volatility. Even in a declining-rate trend, daily fluctuations cause decay.

A practical approach: limit TMF to 5-10% of portfolio as a stock crash hedge rather than betting everything on rate direction. Bond investing references on duration and interest rate risk fundamentals are essential before considering TMF.
