US government borrowing costs reached their highest level since 2007 following an increase in oil prices, with the 10-year Treasury yield peaking at 5.04%. This rise reflects growing concerns about inflation due to rising geopolitical tensions impacting Saudi Arabia's oil exports, pushing global benchmark oil prices above $109 a barrel. The article highlights how tech firms' increased borrowing for data center construction is also contributing to higher yields on government bonds.

Story summary
The 10-year US Treasury yield breached the significant threshold of 5% for the first time since October 2023, driven by escalating inflation fears and energy supply disruptions. This milestone was reached as oil prices surged to over $108 a barrel, amid ongoing conflicts in the Middle East that threaten vital shipping routes like the Strait of Hormuz. The sell-off in bond markets intensified concerns about higher borrowing costs for consumers and businesses, with mortgage rates and auto loans expected to rise. Central banks worldwide are now considering more hawkish policies; the Federal Reserve is likely to raise interest rates this week to combat inflation. Treasury Secretary Scott Bessent's efforts to stabilize government debt have faltered under these pressures.

Why this leaning score
This article does not take a side on a contested political
question, so it has no leaning score. That is an
answer rather than a gap: a match report or a rescue can be warmly
or critically written without being left or right, and scoring it
anyway is how approval of a subject gets recorded as a political
position.
