20-yr US Treasuries (TMF) analysis, July 1, 2026

Key Updates

TMF reversed sharply lower, declining 3.17% to $35.55 as of July 1, 2026, erasing the gains accumulated during the June recovery rally and returning the fund to levels last seen prior to the mid-June rebound. This pullback follows three consecutive positive reports that tracked a cumulative ~7.5% recovery from multi-decade yield highs, signaling the rally has stalled and bearish pressure has reasserted itself. The move is consistent with the broader narrative of elevated long-end yields, geopolitical-driven inflation risk, and structural volatility from convexity hedging flows re-entering the Treasury market.

Current Trend

The trend profile for TMF is decisively bearish across all meaningful timeframes. YTD performance stands at -4.74%, and the 6-month return is -6.96%, reflecting sustained pressure from a "higher-for-longer" rate environment. The 1-month return of +1.75% and 5-day return of +0.54% had suggested a tentative near-term recovery, but today's -3.27% single-session decline has materially eroded that momentum. Key observations include:

• The June recovery rally (~7.5% from trough) has now partially reversed, with TMF giving back approximately 3.2% in a single session.
• The 30-year Treasury yield reached 5.20%—its highest since 2007—and the 10-year yield rose to 4.69%, creating direct headwinds for TMF as a 3x leveraged long-duration instrument.
• The YTD decline of -4.74% understates the volatility experienced, with the fund having traded through a significant drawdown and partial recovery within the period.

Investment Thesis

The bull thesis for TMF rests on the expectation that long-end Treasury yields will peak and decline as inflation pressures prove transitory, economic growth moderates, and the Federal Reserve pivots toward rate cuts. As a 3x leveraged ETF tracking 20-year+ U.S. Treasuries, TMF offers amplified exposure to any duration rally. The bear thesis holds that persistent inflation driven by energy prices and geopolitical conflict (U.S.-Israel-Iran), mounting fiscal deficits, and elevated term premium will sustain or push yields higher, compressing TMF's NAV further. The structural re-emergence of convexity hedging adds a non-fundamental source of yield volatility that complicates timing for long-duration positions.

Thesis Status

The bull thesis has weakened materially following today's reversal. The mid-June recovery had offered a tentative validation of the "yields peaking" narrative, but the 3.17% single-session decline signals that selling pressure remains dominant. Critical thesis checkpoints are not being met:

• The 30-year yield at 5.20% (highest since 2007) is inconsistent with a near-term rate peak scenario.
• Long-term inflation expectations, while anchored (10-year breakeven at 2.39%), have not declined, and energy-driven inflation risks persist with national average gasoline prices at $4.26/gallon.
• The reactivation of convexity hedging—adding interest-rate exposure equivalent to ~$40 billion in 10-year Treasury purchases per Goldman Sachs estimates—introduces a structural headwind that amplifies downside volatility for TMF.
• The bear thesis remains the path of least resistance given the confluence of geopolitical, fiscal, and structural market factors.

Key Drivers

The following factors are actively shaping TMF's price action:

• Geopolitical inflation shock: The U.S.-Israel attack on Iran in late February drove 10-year yields up as much as 70 basis points, with only partial retracement since. Energy prices at $4.26/gallon national average sustain inflation risk. (Morningstar, June 4)
• 30-year yield at 2007 highs: The 30-year Treasury yield hit 5.20%, with strategists warning of a potential move to 5.5%. This directly compresses TMF's NAV through duration losses amplified 3x. (Bloomberg, June 3)
• Convexity hedging resurgence: Over $2 trillion in MBS with coupons of 5%+ now require active hedging, with ~one-third of outstanding mortgage securities trading near par—where convexity sensitivity is greatest. This creates a structural, non-fundamental source of Treasury selling pressure. (Bloomberg, June 4)
• Fiscal deficit and term premium concerns: Investors are demanding greater compensation to hold long-dated Treasuries, reflecting concerns over debt sustainability and elevated borrowing needs. (Bloomberg, June 3)
• Defined maturity ETF expansion: Invesco's launch of BulletShares Treasury Bond ETFs (2027–2031 maturities) reflects growing institutional demand for structured Treasury exposure, potentially diverting flows from leveraged vehicles like TMF toward more targeted, lower-risk alternatives.

Technical Analysis

TMF's price action is technically bearish following the failed recovery attempt. At $35.55, the fund has surrendered a meaningful portion of the June rally gains. Key technical observations:

• Failed rally: The recovery from the multi-decade yield high trough (~$33.20 implied low based on prior reports) reached approximately $36.72 before reversing. Today's close at $35.55 represents a ~3.2% retracement from the recent peak, suggesting the recovery was a counter-trend bounce rather than a trend reversal.
• YTD support zone: With YTD performance at -4.74% from an implied start-of-year price near $37.32, the $35.55 level sits in a zone of continued weakness. A break below the June trough would confirm the primary downtrend's resumption.
• Resistance: The $36.72 peak from the June 18 report now serves as near-term resistance. Reclaiming this level would be required to re-establish a constructive short-term bias.
• Leverage decay risk: As a 3x leveraged ETF, TMF is subject to volatility decay in choppy, range-bound markets—the current environment of alternating sharp moves in both directions is particularly corrosive to long-term NAV.

Bull Case

• 1. Inflation expectations remain anchored despite geopolitical shock: The 10-year breakeven inflation rate stands at only 2.39%—just 10 basis points higher since the Iran conflict began—suggesting bond markets do not expect a sustained inflation spiral, which could limit further yield upside and eventually support a TMF recovery. (Morningstar, June 4)
• 2. "Soft landing plus" scenario limits yield ceiling: Market pricing of resilient growth without runaway inflation implies yields may be near a cyclical peak. If the scenario holds, the case for a gradual yield decline—and TMF appreciation—strengthens. (Morningstar, June 4)
• 3. Equity market vulnerability at elevated yields: With U.S. equities up 27% year-over-year and the 30-year yield at 5.20%, the risk of a stock market correction that triggers a flight-to-safety rotation into Treasuries is non-trivial. Such a rotation would directly benefit TMF. (Bloomberg, June 3)
• 4. Convexity hedging flows can reverse: The same convexity dynamics that amplify Treasury selloffs can accelerate rallies if yields decline—MBS investors would be forced to buy duration as hedges are unwound, potentially creating a self-reinforcing upside move for TMF. (Bloomberg, June 4)
• 5. Institutional appetite for Treasury exposure growing: Invesco's expansion of BulletShares Treasury ETFs—managing $27.6 billion across a $70 billion target maturity market—reflects sustained institutional demand for U.S. government bonds, which could provide a floor for long-duration Treasuries. (PR Newswire, June 10)

Bear Case

• 1. 30-year yield at 2007 highs with further upside risk: The 30-year Treasury yield reached 5.20%, with strategists warning of a potential move to 5.5%—levels not seen since 2004. Each 10 basis point rise in the 30-year yield translates to amplified NAV destruction for TMF given its 3x leverage and ~20-year duration target. (Bloomberg, June 3)
• 2. Geopolitical inflation risk is structural, not transitory: The U.S.-Israel attack on Iran and resulting energy price spike ($4.26/gallon national average) represent a persistent supply-side shock. Elevated oil prices sustain inflation risk and reinforce the "higher-for-longer" rate narrative that is the primary headwind for TMF. (Morningstar, June 4)
• 3. Convexity hedging amplifies downside volatility: Over $2 trillion in MBS with 5%+ coupons are actively being hedged via Treasury futures selling. With ~one-third of MBS near par (maximum convexity sensitivity), any yield rise triggers accelerated hedge rebalancing—a structural, non-fundamental source of selling pressure that disproportionately impacts long-duration instruments like TMF. (Bloomberg, June 4)
• 4. Fiscal deficit and term premium expansion: Investors are demanding greater compensation to hold long-dated U.S. debt, reflecting concerns about debt sustainability and the government's fiscal trajectory. Rising term premium is a structural headwind that can sustain elevated yields independent of Fed policy. (Bloomberg, June 3)
• 5. Defined maturity alternatives divert flows from leveraged products: Invesco's BulletShares Treasury ETF launch provides investors with targeted, non-leveraged Treasury exposure with defined maturity profiles—directly competing for capital that might otherwise flow to TMF, and potentially reducing demand for leveraged long-duration vehicles in a volatile rate environment.
