20-yr US Treasuries (TMF) analysis, December 5, 2025

Published December 5, 2025 · TMF chart, levels and live analysis

Key Updates

TMF has recovered 9.17% since the July 29 report, rising from $36.19 to $39.51, though recent momentum has reversed sharply with a 5.82% decline over the past five days. The YTD performance remains modestly negative at -1.15%, reflecting persistent challenges in the long-duration Treasury space. Concerns about foreign demand for U.S. debt and inflation measurement uncertainties have emerged as new headwinds, while the prospect of mortgage rates declining below 6% signals potential for lower long-term yields that could support TMF's leveraged position.

Current Trend

TMF exhibits a volatile consolidation pattern with conflicting timeframes. The 6-month performance of +5.19% demonstrates medium-term strength, while the sharp 5-day decline of -5.82% and 1-month drop of -4.47% indicate renewed selling pressure. At $39.51, TMF remains down 1.15% year-to-date, suggesting the asset has struggled to establish a sustained uptrend despite the recovery from July's lows. The recent reversal from higher levels indicates resistance near the $42 zone, while support appears to be forming around the $39-$40 range based on current price action.

Investment Thesis

The investment thesis for TMF centers on positioning for a long-term decline in Treasury yields driven by potential Federal Reserve policy shifts, economic deceleration, or flight-to-quality dynamics. As a 3x leveraged long position on 20-year Treasuries, TMF amplifies returns when yields fall and bond prices rise. The thesis depends on sustained demand for long-duration U.S. government debt and stable inflation expectations. However, structural challenges to foreign demand and operational uncertainties in inflation measurement create new dimensions of risk that were not prominent in the previous analysis period.

Thesis Status

The investment thesis faces mixed signals with a neutral-to-cautious outlook. The 9.17% recovery since July validates some aspects of the long-duration Treasury positioning, yet the inability to sustain gains above $40 and the sharp recent decline suggest the thesis remains under pressure. New concerns about foreign buyer dynamics and CPI measurement reliability introduce fundamental uncertainties that could impair long-term Treasury demand. The potential for mortgage rates to decline below 6% in 2026 supports the case for lower long-term yields, but this remains contingent on economic developments not yet fully materialized. The thesis requires continued monitoring as structural demand factors evolve.

Key Drivers

Foreign demand concerns have emerged as a critical factor, with reports highlighting potential troubles for the largest foreign buyer of U.S. debt, which could create ripple effects throughout the bond market and pressure long-duration Treasury prices (Morningstar). Operational uncertainties in inflation measurement have surfaced, with traders preparing to use untested fallback mechanisms for potentially missing CPI data, introducing volatility into inflation expectations that directly impact Treasury valuations (Bloomberg). On the positive side, mortgage rate forecasts suggest potential for rates to dip below 6% with expectations for 2026 pointing toward a more accommodative rate environment that could support long-duration Treasury demand (CNBC).

Technical Analysis

TMF's technical structure shows a recovery rally from the July low of $36.19 that has stalled near the $42 level, followed by a sharp 5.82% pullback over five days to the current price of $39.51. This price action suggests the asset is trading within a range between $36-$42, with the recent decline testing the lower boundary of this consolidation zone. The 6-month gain of 5.19% indicates a higher low formation compared to earlier 2025 levels, but the failure to break above resistance and the accelerating short-term decline signal weakening momentum. Volume and volatility patterns typical of leveraged ETFs amplify these movements, making $39 a critical near-term support level. A break below this zone would target the July lows, while a recovery above $41 would be needed to resume the uptrend.

Bull Case

  • Mortgage rate forecasts indicating potential decline below 6% suggest a broader trend toward lower long-term interest rates, which would directly benefit 20-year Treasury prices and TMF's leveraged position (CNBC).
  • The 6-month performance of +5.19% demonstrates medium-term accumulation and investor interest in long-duration Treasuries despite near-term volatility, indicating underlying demand support for the asset class.
  • The 9.17% recovery since the July 29 report from $36.19 to $39.51 validates the oversold condition identified in the previous analysis and suggests technical resilience at lower price levels.
  • Expected 2026 rate environment points toward more accommodative monetary policy conditions that typically favor long-duration fixed income instruments, creating a favorable backdrop for Treasury appreciation (CNBC).
  • Current consolidation near $39-$40 may represent accumulation before the next leg higher, with the asset holding above the critical July support level despite recent selling pressure.

Bear Case

  • Structural concerns about the largest foreign buyer of U.S. debt threaten to reduce demand for Treasuries at a fundamental level, potentially leading to higher yields and sustained pressure on long-duration bonds (Morningstar).
  • Operational uncertainties in CPI measurement with untested fallback mechanisms introduce unpredictable volatility into inflation expectations, creating an unstable environment for fixed income valuation (Bloomberg).
  • The sharp 5.82% decline over five days and 4.47% drop over one month indicate renewed selling momentum and potential breakdown of the recovery rally established since July, suggesting weakening technical structure.
  • YTD performance of -1.15% reflects persistent inability to generate positive returns despite multiple rally attempts, indicating structural headwinds that continue to weigh on long-duration Treasury performance throughout 2025.
  • Ripple effects from foreign buyer troubles could cascade through the bond market, creating liquidity concerns and wider spreads that would disproportionately impact leveraged instruments like TMF (Morningstar).
