Global bond yields surge as markets brace for higher inflation

Global bond markets are experiencing one of their sharpest repricings in years, with government bond yields reaching levels not seen in decades across several major economies.

In the U.S., the benchmark 10-year Treasury yield has climbed above 5.2%, reaching around 5.27% and its highest level since 2007, while the 30-year yield has moved above 5.5%, approaching levels last seen in 2002. The move is also global: France’s 10-year yield is around 4.76%, its highest since 2008, while Japan’s 10-year yield has reached 3%, a level not seen since 1996.

The rise in yields reflects a combination of renewed inflation concerns, expectations for higher interest rates, heavy government borrowing and growing uncertainty over the global economic outlook.

The biggest catalyst for this surge has been the ongoing conflict in the Middle East and its impact on energy markets. Oil prices have risen sharply amid concerns over supply disruptions and uncertainty surrounding the Strait of Hormuz. Brent crude has recently moved above $100 a barrel, raising fears that higher energy costs could keep inflation elevated for longer.

That is changing expectations for monetary policy. Markets that had been anticipating further rate cuts are now increasingly considering the possibility that central banks may need to keep rates higher for longer, or even raise rates again if inflationary pressures persist.

How are rising yields affecting markets?

The impact is spreading across financial markets. Gold and silver have come under pressure as higher bond yields increase the opportunity cost of holding assets that do not generate interest income. The effect is particularly strong when real yields rise and the dollar strengthens. Although geopolitical uncertainty normally supports precious metals, the rise in bond yields is currently offsetting some of that safe-haven demand.

Equities are also facing pressure. Higher Treasury yields increase the discount rate used to value future corporate earnings, making highly valued growth and technology stocks particularly sensitive to rising rates.

However, the equity market has shown considerable resilience. Strong demand for artificial intelligence infrastructure and continued spending by major hyperscalers on data centers, semiconductors and cloud computing are supporting technology earnings and helping absorb some of the pressure from higher yields.

This has created a tug-of-war in equities: higher yields are putting pressure on valuations, while strong AI investment and corporate earnings are providing support.

What happens if the conflict continues?

The outlook for the remainder of 2026 will depend heavily on developments in the Middle East. As long as the conflict remains unresolved and energy supplies remain at risk, oil prices could stay elevated. Prolonged high energy prices would keep inflation expectations under pressure and make it more difficult for central banks to cut interest rates. That could keep government bond yields elevated or push them even higher.

If the 10-year Treasury yield remains above 5% for an extended period, the pressure on equity valuations could intensify, particularly if higher borrowing costs eventually begin to slow economic growth. Corporate refinancing costs would also increase, while governments would face higher interest expenses as existing debt is rolled over. The biggest risk for markets would therefore be a combination of persistent inflation, higher yields and weakening economic growth.

What could change the picture?

The most important catalyst for a reversal would be a meaningful de-escalation or resolution of the Middle East conflict. A ceasefire, normalization of energy flows and reduced risks around the Strait of Hormuz could trigger a significant decline in oil prices. Lower energy costs would reduce inflation expectations and potentially remove some of the pressure on central banks to maintain restrictive monetary policy.

That could lead to falling bond yields, weaker rate-hike expectations and easier financial conditions. Lower yields would also reduce pressure on equity valuations and the opportunity cost of holding gold and silver.

For now, however, the relationship between oil, inflation, interest rates and bond yields remains firmly at the center of the market.
