Global Bond Sell-Off Resumes as Oil Jumps 6% Above $107
3 articles · Updated · The Guardian · Sep 10
Summary
UK 10-year gilt yields climbed above 5.37% on Thursday—the highest since 2007—as a renewed global bond sell-off lifted borrowing costs across major economies.
Oil surged 6% to above $107 a barrel after Houthi advances on Yemen’s Red Sea coast raised fears for Saudi crude exports, intensifying inflation worries and expectations of higher interest rates.
The pressure spread across markets: US 10-year Treasury yields rose to 4.92%, while 30-year yields hit their highest since 2007 despite Scott Bessent’s $6 billion bond buyback a day earlier.
Central banks are reinforcing that shift, with the ECB raising its main rate to 2.5% and the Bank of England expected to hold at 3.75% next week as policymakers assess the oil shock.
For governments and households, higher yields threaten fiscal plans and consumer finances, with UK petrol already up 6p a litre this month and some banks lifting mortgage rates.
Will the Treasury's multi-billion dollar buyback actually tame surging mortgage rates, or is it just a temporary band-aid for deeper financial pressures?
Could the end of cheap government borrowing signal a healthy economic normalization rather than the looming fiscal disaster that experts fear?

The September 2026 Treasury Buyback: Why $6 Billion Wasn’t Enough to Halt the U.S. Yield Spike
Overview
On September 9, 2026, the U.S. Treasury announced a $6 billion buyback of government debt, but this fell short of Wall Street’s expectations and disappointed investors. This disappointment triggered a sell-off in long-term Treasuries, causing yields to surge. The higher yields immediately strengthened the U.S. dollar and pushed down gold prices. Rising yields also increased government borrowing costs, made mortgages more expensive, and forced companies to delay investments. These market moves were fueled by large fiscal deficits, ongoing geopolitical tensions, and global capital shifts, showing how policy actions and economic pressures combined to drive yields higher and impact the broader economy.
