Stagflation: Central Banks Trapped by $108 Oil

An Oil Shock Here to Stay

The Strait of Hormuz, through which about 20% of the world's crude passes, remains paralyzed by a dual Iranian-American blockade. As of Monday, April 27, 2026, Brent was trading around $108 a barrel and WTI around $96, levels that extend the upward trend already observed in recent days. The diplomatic deadlock between Washington and Tehran diminishes any prospect of a rapid de-escalation: Donald Trump stated that the United States no longer wished to engage in direct negotiations, while Iran accused Washington of having derailed the talks held in Pakistan.

Tehran is proposing a multi-step plan—ceasefire, reopening of Hormuz, postponement of nuclear discussions—but Washington demands that the nuclear issue be addressed first. This friction point maintains a high risk premium in oil markets. An Iranian representative from the oil sector stated that even reopening the strait might not necessarily bring prices below $80—a claim to consider with caution, coming from an involved party, but one that reflects a growing sentiment in markets: the possibility of a new norm with sustainably higher energy prices.

The shock is already impacting the real economy. Transavia France announced targeted flight cancellations in May and June, directly citing the geopolitical context's impact on rising kerosene prices. While the company specifies that these cancellations represent less than 2% of its schedule, this signal illustrates a broader risk of price increases or supply reductions across the entire airline industry, a sector heavily dependent on fuel.

European Domestic Demand Weakens Under Energy Strain

On the demand side, signs of deterioration are piling up, particularly in Europe. The NIM/GfK index of German consumer sentiment is expected to fall to -33.3 points in May, from -28.1 in April, marking its lowest level since February 2023. The rise in energy prices is already impacting income expectations and the propensity to consume in the largest economy of the eurozone.

This decline is significant because it occurs even before the full impact of energy cost increases has filtered through to consumer prices. Second-round effects—passing on to food, transportation, services—could further intensify pressure on households in the coming months. Given its economic weight, Germany serves as a leading indicator for overall European economic conditions.

It's precisely this combination—imported inflation via the energy channel on one side, weakening consumption on the other—that shapes the most uncomfortable environment for monetary policymakers. Prices are rising not because demand is too strong, but because the supply of raw materials is contracting. This is a classic stagflation scenario, where the usual monetary policy tools lose some of their effectiveness.

Fed, ECB, BoJ, BoE: A Dilemma With No Simple Solution

The Federal Reserve, the European Central Bank, the Bank of Japan, and the Bank of England are all approaching a series of monetary decisions in this challenging environment. With inflation driven by an external supply shock, lowering interest rates to support activity risks cementing inflation expectations on the rise. Conversely, maintaining high rates—or increasing them—would exacerbate the already observable demand slowdown.

This dilemma is particularly acute for the ECB, directly exposed to the contraction in German consumption and Europe's energy dependency. The Fed faces a similar challenge, although the U.S. economy is less exposed to crude oil imports transiting through Hormuz. The BoJ, which has barely begun a normalization of its monetary policy, sees its timeline potentially disrupted by rising imported energy costs. The Bank of England, meanwhile, is dealing with a still tight labor market and persistent services inflation.

In this scenario, interest rate markets are gradually factoring in the possibility of a prolonged status quo for the four major central banks. The hope for rapid rate cuts, present at the beginning of the year, now faces the reality of an energy shock that has not seen a diplomatic resolution, with its effects spreading simultaneously on prices and demand.
