The 30-year U.S. Treasury yield reached its highest level since 2004 on Sept. 24, rising to roughly 5.3% to 5.37% as longer-term government bonds sold off.

The move reflects heightened concern about inflation, heavy government borrowing and fiscal-debt issues. Falling bond prices push yields higher, increasing the cost of borrowing across the economy.

Mortgage rates, corporate financing costs and the federal government’s interest expenses are all exposed to changes in long-term Treasury yields. Higher borrowing costs can also weigh on economic growth by making credit more expensive.

The bond-market move comes as investors assess inflation and fiscal policy, with additional data releases and policy announcements likely to influence expectations for yields.
