US Treasury Yields Hit 25-Year High, Raising Borrowing Costs
A government bond is like an IOU from the government.
People lend money to the government and receive payments in return.
The yield tells them how much they may earn from that loan.
When inflation rises, future payments may buy fewer goods, so investors often demand better returns.
Investors can also sell existing bonds, causing their prices to fall.
When bond prices fall, their yields rise.
The US government then has to offer higher returns when it borrows more money.
This can leave less money in its budget for other priorities.
Higher yields can also make business loans and home loans more expensive, which may slow the economy.
The yield on the 30-year US Treasury bond reached its highest level in about 25 years on Tuesday.
Bond yields reflect the return lenders expect, while bond prices and yields generally move in opposite directions.
Inflation concerns and strong demand for loans are pushing investors to seek higher returns across borrowing durations.
Higher yields increase borrowing costs for the US government and could direct more budget money toward interest payments.
Because US Treasury debt is viewed as highly safe, rising US yields can raise borrowing costs for governments, businesses, and households worldwide.
