The iShares 20+ Year Treasury Bond ETF (TLT) has fallen to its lowest level since 2004 and is down more than 50% from its all-time high as volatility persists in the U.S. bond market. ETF Db data shows the fund attracted more than $4.7 billion in inflows over the last 30 days, lifting total assets above $46 billion despite the sell-off. The 30-year Treasury yield reached a two-decade high of 5.336%, briefly falling to 5.18% after Treasury Secretary Scott Bessent launched a major bond buyback operation before rising to 5.276%. Rising government debt, widening budget deficits and signs of economic weakness could keep pressure on bond yields. TLT has declined from a year-to-date high of $90.87 to $82.05, below the $82.80 support level and all moving averages. Its bearish flag pattern points to a potential fall toward $80, although a move above the 50-day moving average at $83.6 would invalidate that outlook.
