20-yr US Treasuries (TMF)

Key Updates

TMF declined 2.02% to $34.88 since the April 27 report, extending losses to $35.60 from $36.34 in early April and marking a continued deterioration in long-duration Treasury performance. The YTD decline has widened to -6.54%, while the 6-month loss stands at -12.67%, reflecting persistent pressure on long-dated bonds. Seven new developments emerged, centered on structural concerns about Treasury market stability, debt management strategy shifts, and institutional positioning changes. The critical question from Morningstar regarding whether the historical pattern of buying Treasuries near 5% yields remains valid highlights growing uncertainty about traditional valuation frameworks.

Current Trend

TMF remains in a confirmed downtrend with accelerating losses across all timeframes. The 1-month decline of -4.52% and 6-month loss of -12.67% demonstrate sustained selling pressure, while the brief 1-day gain of 1.40% represents technical noise rather than trend reversal. The current price of $34.88 marks the lowest level in the tracking period, breaking below the previous April 2 low of $34.81. The pattern of lower lows and lower highs persists, with resistance now established at the $36.34 level from early April. The 5-day decline of -2.41% confirms that even modest rallies are being sold, consistent with the deteriorating technical structure observed since March.

Investment Thesis

The investment thesis for long-duration Treasuries faces fundamental challenges as structural market dynamics shift. Traditional valuation metrics suggesting attractiveness near 5% yields are being questioned by institutional investors, with Vanguard noting 10-year yields above 4.3% as attractive relative to their 3.75%-4.25% fair-value range. However, the IMF's warning that Treasury safety premiums have eroded from 55 basis points in 2019 to 35 basis points introduces uncertainty about traditional risk-free rate assumptions. The thesis must now account for elevated structural risks including Treasury Department debt management changes, hedge fund positioning at 8-10% of the market, and sustained 6% fiscal deficits. The potential for Federal Reserve rate cuts remains supportive, with Franklin Templeton forecasting 10-year yields approaching low 4% range, but this scenario requires geopolitical stability and inflation moderation.

Thesis Status

The investment thesis has deteriorated materially since the April 27 report. While institutional buyers like Vanguard are accumulating positions at current yield levels, multiple structural headwinds have emerged that challenge the historical playbook. The Treasury's potential shift away from short-term bill issuance toward longer-term securities could increase supply pressure on 20-year bonds. The Apollo warning about hedge fund positioning exceeding $6 trillion in leveraged exposure introduces tail risk of forced unwinding. Most critically, the IMF's assessment that the Treasury safety premium has compressed by 36% since 2019 suggests fundamental repricing of risk-free assets. The thesis remains conditionally viable if Federal Reserve easing materializes and geopolitical risks fade, but the risk-reward profile has shifted unfavorably with downside protection eroding and structural vulnerabilities increasing.

Key Drivers

Treasury debt management strategy represents the primary near-term catalyst, with Wednesday's quarterly refunding statement potentially signaling increased issuance of longer-term notes and bonds to address the near-$2 trillion annual deficit. This shift would directly pressure TMF by increasing supply of 20-year securities. Hedge fund positioning has emerged as a critical stability concern, with holdings reaching 8-10% of the $31 trillion market supported by over $6 trillion in leveraged financing, creating potential for disruptive unwinding. The erosion of Treasury safety premiums documented by the IMF reflects sustained 6% fiscal deficits and historically high borrowing needs that are fundamentally repricing risk-free rates. Geopolitical developments provide countervailing support, with major funds piling into Treasuries as Iran conflict risks fade and two-year yields dropping eight basis points. The Federal Reserve policy trajectory remains uncertain, with institutional expectations of one rate cut this year potentially supporting duration assets, though timing remains undefined.

Technical Analysis

TMF exhibits deeply oversold conditions with price declining to $34.88, the lowest level in the tracking period and below the previous $34.81 support from April 2. The downtrend structure remains intact with resistance established at $36.34 (early April high) and intermediate resistance at $35.60 (April 27 level). The 5-day decline of -2.41% following a brief 1.40% daily gain confirms that rallies are being sold into, characteristic of established downtrends. Volume patterns are not provided, but the consistency of selling pressure across 1-month (-4.52%), 6-month (-12.67%), and YTD (-6.54%) timeframes indicates broad-based liquidation rather than episodic selling. The price action since March has established a pattern of lower highs at $36.34, $35.60, and now $34.88, with no meaningful support levels visible until examining pre-tracking period data. The technical structure suggests further downside risk unless a catalyst emerges to break the established trend, with next logical support zones likely in the $33-34 range based on the current rate of decline.

Bull Case

• Vanguard and major institutional investors are actively accumulating Treasuries at current yield levels above 4.3%, viewing them as attractive relative to 3.75%-4.25% fair-value range, providing demand support at these prices. Source
• Geopolitical risk premium is declining as Iran conflict risks fade following ceasefire, with major funds reallocating capital into Treasuries and two-year yields already dropping eight basis points, creating tailwinds for duration assets. Source
• Federal Reserve rate cut expectations remain intact with institutional consensus of one cut this year, while Franklin Templeton forecasts 10-year yields approaching low 4% range as oil prices decline and inflation pressures moderate. Source
• Historical pattern of buying long Treasuries when yields approach 5% has proven successful over recent years, suggesting current levels near this threshold may represent attractive entry points despite structural concerns. Source
• Money-market fund assets of $7.6 trillion with 42% invested in Treasuries provide substantial demand base, while proposed GENIUS Act could drive additional institutional inflows into Treasury securities. Source

Bear Case

• Treasury Department faces pressure to shift from short-term bills to longer-term securities to address near-$2 trillion annual deficit, with Wednesday's refunding statement potentially signaling increased supply of 20-year bonds that would directly pressure TMF. Source
• Hedge funds now hold 8-10% of the $31 trillion Treasury market with over $6 trillion in leveraged financing, creating significant tail risk of forced unwinding that could trigger disruptive selloffs across global fixed income markets. Source
• IMF warns Treasury safety premium has eroded from 55 basis points in 2019 to 35 basis points currently due to sustained 6% fiscal deficits and historically high borrowing needs, fundamentally repricing the risk-free rate and reducing traditional valuation support. Source
• US budget deficit averaging 6% of GDP over past three years is expected to persist throughout the coming decade, driving continuous high issuance that pressures prices and raises questions about debt sustainability. Source
• Development banks and supranational institutions are challenging Treasury dominance as investors diversify away from US government bonds due to policy unpredictability and rising credit risk, with SSA premiums over Treasuries narrowing significantly. Source
