The bond market is flashing a warning that investors cannot easily ignore. The 30-year Treasury yield climbed to 5.31% on Monday, reaching its highest level since June 2007.

• iShares 20+ Year Treasury Bond ETF stock is at significant support. What’s behind TLT weakness?

The move is notable because long-term yields are rising even as expectations for a near-term Federal Reserve hike have eased.

CME FedWatch Tool shows there’s only a 32% chance of a 25-basis-point rate hike in September, down from 53% a week ago.

That suggests investors are demanding more compensation for holding long-duration debt, amid concerns over government deficits and heavy borrowing.

The iShares 20+ Year Treasury Bond ETF (NASDAQ:TLT) dropped to $81.38 on Monday, hitting the lowest levels since June 2004.
