The global government bond market has experienced a sharp sell-off over the past week, driven by rising inflation risks triggered by the Middle East conflict. Energy prices have surged, pushing global energy prices higher, and Brent crude has climbed to around $92 per barrel, up from $72 per barrel before the conflict began.

The sell-off has been widespread, with bond prices moving in the opposite direction of yields. As investors sell bonds, yields rise, and this has been evident across several major markets. The benchmark 10-year UK government bond yield climbed to 4.62%, while the 10-year US Treasury yield rose to 4.13%, its largest weekly increase since the US-China trade tensions last year.

Interest Rate Expectations:

Traders have begun unwinding earlier bets that central banks would soon reduce borrowing costs. In the United Kingdom, financial markets had been pricing in two quarter-point interest rate cuts by the Bank of England during 2026, but now traders see only about a 50% chance of a single rate cut. In the eurozone, swap markets have even begun pricing the possibility that the European Central Bank could raise interest rates slightly instead of cutting them.

Market Reactions:

Not all bond markets have reacted in the same way. The UK bond market has experienced some of the largest moves because investors had previously expected relatively aggressive rate cuts there. Britain's energy mix also leaves the economy more exposed to changes in gas prices, making inflation risks particularly sensitive to energy shocks.

Economic Outlook:

Analysts caution that markets may be reacting too quickly, but economists point out that central banks may respond differently this time. If higher energy prices begin to slow economic growth, policymakers could prioritise supporting the economy rather than raising rates again. For now, however, bond investors are adjusting their expectations, and the sharp rise in yields over the past week shows how quickly geopolitical events can ripple through financial markets and reshape the outlook for interest rates around the world.
