Oil above $100 lifts bond yields as inflation worries intensify

In European trading today, oil prices and bond yields continued their climb, serving as a clear signal that inflation risks remain a key focus for markets.

Brent crude rose by more than 1% to surpass $102, while WTI crude advanced 1.5% to $97.50, with ongoing Middle East tensions keeping supply disruption concerns alive.

Meanwhile, US Treasury yields also rose, with the 10-year note climbing 3 basis points to 4.867%, the highest since 2023. The US Treasury announced a $6 billion bond buyback overnight, but that is not enough to keep the bond vigilantes at bay. The 5% level remains in traders' sights, with the upcoming US CPI report offering another possible trigger.

The problem for markets is straightforward: as oil prices rise, they directly boost inflation pressures and broader inflation expectations.

Eventually, higher energy costs will pass through to transportation, production, and consumer prices. Consequently, investors are requiring higher bond yields as they reconsider how much leeway central banks—particularly the Federal Reserve—have to maintain current monetary policy.

Although $100 oil is already causing ripples in markets, the greater concern is that persistently higher energy prices could lead to a bigger set of problems down the road.

Oil is not the sole worry for bond markets and central banks at this point.

Concerns about the large US deficit, heavy government borrowing, and disappointment over the Treasury's $6 billion bond buyback are applying pressure on the long end of the yield curve. This creates an uneasy mix for markets: higher energy costs and higher borrowing costs simultaneously.

The moves seen today act as a timely reminder ahead of Thursday's US CPI report. Ultimately, major central banks will find it harder to disregard the signals coming from both the oil and bond markets.
