The global bond market is being forced to reconsider the idea that the next major move in interest rates would be down. Oil prices surged again on 10 September, with Brent crude trading around $107 a barrel as Middle East conflict disrupted major shipping routes and raised the risk of a longer energy shock.

At the same time, US Treasury yields climbed sharply, the European Central Bank raised rates to 2.5%, and government bond yields across Europe moved to levels not seen for years. Higher energy costs matter because they can lift headline inflation quickly, squeeze household spending and complicate the path back toward central-bank targets.

The bond selloff is really a policy repricing

The important move is not simply that oil is more expensive. Investors are changing assumptions about how long central banks can tolerate elevated inflation. Reuters reported that traders put a roughly 70% probability on a Federal Reserve rate rise at the next meeting after US producer-price data and the renewed oil spike.

That repricing also raises the discount rate used to value equities, increases refinancing costs for companies and governments and makes highly valued growth stocks more sensitive to every inflation release. The market can absorb expensive oil more easily if it is temporary. It is harder to absorb if it changes the expected path of policy rates.

Our view: energy is once again the macro variable that can break the consensus

Global Markets Review's view is that the next few weeks should be treated as an inflation-duration test. The level of oil matters, but persistence matters more. If crude remains above $100 and transport disruption spreads into freight, diesel and natural gas, the inflation shock becomes broader than a single commodity move.

The checkpoints are US CPI, central-bank guidance, inflation breakevens and the shape of government yield curves. The most important question is no longer whether markets can tolerate one bad energy week. It is whether the entire 2026 rate-cut narrative has to be rewritten.

Frequently asked questions

Why are bond yields rising in September 2026?

Markets are repricing inflation and interest-rate risk as oil prices rise sharply and central banks signal that additional tightening may be necessary.

Why does $100-plus oil matter for stocks?

Higher oil can lift inflation, raise interest-rate expectations and reduce the valuation investors are willing to pay for future earnings.

What is the main risk now?

The main risk is that an energy shock lasts long enough to affect broader inflation and force central banks to keep rates higher for longer.
