US Treasury yield hits 19-year high as oil keeps pressure on markets

The benchmark 10-year US Treasury yield briefly climbed above 5.27% on Monday, its highest level since 2007, before easing to about 5.23%, according to Associated Press reporting. Reuters and the Financial Times separately described the deepening bond sell-off as investors weighed elevated oil prices, inflation risk and the prospect of further interest-rate increases.

Brent crude remained near $106 a barrel in early Asian trading on Tuesday after hopes for a US-Iran agreement weakened. Reuters reported that major Middle Eastern producers exported more crude in September, but some shipments still relied on costly workarounds. That means higher prices reflect both current logistics and the market's assessment of future disruption; they are not proof that all Gulf exports have stopped.

Bond yields rise when prices fall. The 10-year Treasury yield is widely used as a reference for mortgages, corporate borrowing and other financing, so a sustained move can affect households and companies outside the oil market. Asian equities were mixed to weaker as trading opened, while yields also rose in several regional bond markets.
