20+ Year US Treasuries (TLT) analysis, September 2, 2025

Published September 2, 2025 · TLT chart, levels and live analysis

Key Updates

TLT has kept sliding since the last report, down 2.32% to $85.75. The Fed has signaled it is ready to cut rates in September after Powell's Jackson Hole speech, but the bond market is not buying it. Seasonal patterns point to an 87% chance of a September pullback in 30-year Treasuries, adding more pressure on TLT.

Current Trend

TLT is in a steady downtrend, with selling accelerating over the past month (-2.36%) and six months (-7.23%). At $85.75, the ETF is well off its April 2025 highs. The 12-month return shows a modest 1.81% decline, masking much sharper swings in between. Near-term momentum has turned more negative, with a 1.22% loss over the last five days.

Investment Thesis

The TLT thesis rests on expected Fed rate cuts and a potential economic slowdown, both of which historically support long-duration bonds. But the setup is muddier now, with inflation risks from potential tariffs and structural shifts in monetary policy. Seasonal patterns have typically favored bonds into the fall, but 2025 is breaking from that script.

Thesis Status

The thesis is under pressure. Despite the Fed's willingness to cut, the bond market is showing little enthusiasm, pointing to real doubts among participants. The gap between Fed intentions and market reaction creates near-term uncertainty and calls for a rethink on timing.

Key Drivers

Fed rate decisions remain the main driver, and Powell's Jackson Hole remarks boosted expectations for a September cut. But seasonal data points to an 87% chance of a September correction, and tariffs could reignite inflation. Technicals also stand out: the seasonal peak came in April instead of the usual August.

Technical Picture

TLT looks weak on the charts, with a clear downtrend from the April highs. The current $85.75 level sits well below prior resistance. The slide is speeding up — down 0.99% on the day and 1.22% over five days — a sign of growing bearish pressure. With no meaningful support nearby, further downside looks open.
