ECB Rate Hike Debate After Oil Price Jump

French commentary in the supplied source argues that the recent oil spike should not be confused with the kind of broad-based inflation shock that forced central banks into aggressive tightening in 2022. Euro zone consumer prices, it says, rose from 1.7% year on year in January to 3.2% in spring before easing to 2.9%, while Belgium’s inflation slowed from 4.2% to 3.6%. Excluding energy, euro zone inflation has remained in a 2.2% to 2.4% range through the year, close to the ECB’s 2% goal.

The market is not waiting for reassurance. Futures now price a 95% chance of another ECB rate increase and a 72% chance of a Fed move by year-end, according to the source. But the same commentary argues that central bankers risk “fighting the previous war” if they keep treating oil as the main inflation engine. Oil has climbed back to about $85 a barrel on war fears, well below the $138 peak seen in April, and the article expects the move to fade.

For investors, the more important signal is the yield curve. The gap between 10-year and three-month Belgian rates is now 1.27 percentage points, 1.59 points in France and 0.90 point in Germany. In the U.S., the 10-year Treasury yield at 4.802% sits above the two-year at 4.375%, leaving a positive spread of about 0.43 point. Those curves are steep enough to support lending, but they also show how quickly policy expectations can move if central banks overreact to temporary energy shocks.

That distinction matters for banks and credit-sensitive equities. A steeper curve helps lenders borrow short and lend long, improving margins and supporting loan growth, especially for small and mid-sized European companies. An inverted curve does the opposite and has long been treated as a recession warning. The argument in the source is that the ECB should not tighten so far that it flattens the curve and damages credit creation just as euro zone inflation is cooling on its own.

Broad money growth gives the same message. Euro zone M3 rose just 3.3% in June from a year earlier, down from a 12.5% peak in 2021, suggesting monetary conditions are far less inflationary than they were during the pandemic period. That weakens the case for a deep tightening cycle and strengthens the case for ECB policymakers to monitor the curve before going further.

Treasury exchange-traded funds suggest bond investors are already positioning for a policy debate rather than an outright inflation scare. TLT, which tracks long-duration U.S. government bonds, closed at 82.20 on Sept. 8, below both its 50-day moving average of 82.85 and 200-day average of 84.57. IEF, the intermediate Treasury ETF, was at 92.16, also under its 50-day and 200-day averages. Those levels point to caution on duration even as the curve remains positive.

The bull case for further ECB hikes is that core inflation may prove stickier than expected if oil keeps feeding wages and transport costs. The bear case is that headline inflation will keep retreating once the energy shock fades, leaving the ECB with unnecessarily tight policy if it keeps chasing the move. For now, the yield curve says the latter risk deserves more attention.

The ECB’s challenge is less about whether to acknowledge oil’s effect and more about whether it can resist making policy against a temporary price shock. If it watches the curve closely, it can avoid tightening into weakness and preserve the credit conditions that still underpin euro zone growth.
