Key Updates
Since the last report on September 24, 2026, TMF has declined a further 6.47% to $25.68, bringing year-to-date losses to 31.19%. The sell-off has intensified, driven by 30-year Treasury yields reaching 5.58%, the highest level since 2002, after six consecutive days of increases. Notably, a significant sentiment shift has occurred: Jim Bianco of Bianco Research, a long-time Treasury bear, has turned bullish for the first time since 2020, citing 5.25% yields as offering a "big fat cushion" against further losses. Additionally, the Treasury market is showing signs of a crowded short trade, raising the risk of a potential short squeeze. These developments create a complex picture: extreme bearish momentum meets growing value signals from prominent market participants.
Current Trend
The prevailing trend for TMF remains firmly bearish, with the fund continuing to make new lows. The 6-month decline of 28.92% and the 1-month drop of 16.97% demonstrate accelerating downside momentum. The price action is being driven by the relentless rise in long-term Treasury yields, with the 30-year yield now at 5.58% and approaching its 2002 peak. This yield surge reflects persistent market concerns about inflation and fiscal sustainability, with the US government's $40 trillion debt burden cited as a key factor. Despite some dovish commentary from Federal Reserve officials, bond yields have continued to rise, indicating that the market is demanding a higher term premium for holding long-duration debt. The current trend shows no signs of reversal based on price data alone, though the crowded short positioning noted in the news suggests the potential for sharp, sudden reversals if sentiment shifts.
Investment Thesis
The investment thesis for TMF centers on the proposition that long-duration Treasury bonds, having been in a prolonged bear market, are approaching a point of attractive valuation where the risks are increasingly priced in. The recent news provides support for this view: Jim Bianco argues that negative sentiment on inflation, deficits, and debt is "already reflected in prices" and that 5.25% yields with ~3% inflation offer compelling risk-adjusted returns. He notes that yields would need to spike to roughly 6% for him to lose money on a one-year horizon. However, the counter-thesis remains dominant in the market: persistent inflation and fiscal concerns continue to drive yields higher, with the 30-year yield hitting levels not seen in over two decades. The market is also heavily positioned for further declines, with record options activity on long-bond ETFs and traders betting on continued price drops. The thesis is therefore in a state of tension between valuation arguments and momentum-driven market dynamics.
Thesis Status
The investment thesis is showing early signs of potentially shifting toward a more balanced risk-reward profile, though the price action does not yet confirm a reversal. The current situation increasingly aligns with the contrarian value argument: a well-known bond bear has turned bullish, positioning is crowded on the short side, and yields have reached two-decade highs. However, the thesis is not yet confirmed, as the market continues to sell off and yields keep rising. The key risk to the thesis is that yields could continue to march higher if inflation remains sticky or if fiscal concerns intensify. The thesis status can be characterized as "under evaluation" — the fundamental case for value is strengthening, but the technical trend remains firmly bearish, and there is no evidence yet of a bottoming process in price action.
Key Drivers
The primary drivers of TMF's price movement remain interest rate expectations and fiscal concerns:
- Rising yields: The 30-year Treasury yield reached 5.58%, the highest since 2002, and the 10-year yield hit 5.25%, a near two-decade high, driving continued losses in long-duration bonds (Bloomberg).
- Fed policy uncertainty: Market odds for a 25-basis-point hike at the October meeting have fallen below 50% after dovish comments from New York Fed Governor John Williams, yet yields continue to rise, indicating other factors are at play (Morningstar).
- Fiscal concerns: The US government's $40 trillion debt burden is cited as a key driver of the long-term yield surge (Bloomberg).
- Market positioning: Crowded short positioning in Treasury futures raises the risk of a squeeze, which could accelerate price moves (Bloomberg).
- Economic data: Stronger-than-expected US purchasing managers' data intensified expectations for further Fed rate increases, pushing yields higher (Morningstar).
Technical Analysis
TMF is trading at $25.68, having declined 31.19% YTD. The fund has been in a persistent downtrend, with the 1-month decline of 16.97% indicating accelerating bearish momentum. The price action shows no signs of stabilizing, with each rally attempt being sold. The 30-year yield's approach to its 2002 high of 5.58% represents a critical technical level — a break above could trigger further selling, while a rejection could provide a catalyst for a bounce. The crowded short trade in Treasury futures noted in the news suggests that any positive surprise could trigger a rapid short-covering rally. However, based purely on price data, there are no established support levels visible, and the trend remains firmly downward. The record-low levels of the biggest long-bond ETF (Bloomberg) confirm that the technical picture remains bearish with no signs of a bottom.
Bull Case

- The "big fat cushion" argument: yields would need to spike to roughly 6% for a one-year holding period to lose money, providing a significant buffer against further losses (Morningstar).
