Middle East Crisis: Fed and Bank of Japan Hold Rates Steady, Inflation Risk Persists

The Transmission Mechanism: How an Oil Shock Paralyzes Monetary Policy

An oil supply shock acts like a grain of sand in the gears of global monetary policy. When crude oil supply is threatened or disrupted in this strategic region, oil prices rise automatically, which in turn affects production and transportation costs, ultimately impacting consumer prices. This type of shock presents central banks with a classic yet formidable dilemma: imported inflation accelerates just as economic growth slows down.

For a central bank, raising interest rates could help contain inflation, but it might exacerbate the economic slowdown. Conversely, lowering rates to support economic activity could further fuel inflationary pressures. This is exactly the predicament that explains the simultaneous inaction of the Fed and the BoJ. Both institutions explicitly acknowledge significant uncertainty regarding the magnitude and duration of the energy shock, deeming the situation too unstable to act in either direction.

In the United States, the economy shows signs of slowing, particularly in employment and growth sectors. The Fed anticipates a trajectory of moderate growth coupled with persistent inflation, a mix that justifies in its view maintaining rates in the 3.50% – 3.75% range, with only one rate cut considered at this stage. In Japan, the BoJ believes the economy is recovering moderately despite a challenging international environment, supporting the decision to keep the policy rate at 0.75%. In both cases, the Middle East oil shock is the key factor driving this cautious stance.

Internal Dissensions: When Monetary Committees Break Apart

The apparent inactivity of the Fed and the BoJ should not overshadow the tensions running through their monetary policy committees. Within the Bank of Japan, some members voted in favor of a rate hike, believing that domestic recovery and inflationary pressures warranted further tightening. These dissenting voices consider that maintaining such a low benchmark rate amidst an inflationary supply shock poses a risk to medium-term price stability.

On the Federal Reserve side, the divide is mirrored. Some members of the FOMC are advocating for a rate cut, arguing that the slowdown in employment and American growth necessitates a preemptive monetary easing. According to this perspective, waiting too long to act could turn a moderate slowdown into a more severe contraction. These differences reflect the fundamental challenge of balancing support for economic activity against combating inflation in an environment dominated by an exogenous supply shock.

These dissenting votes, relatively rare when occurring simultaneously within the world's two largest central banks, send a strong signal. They reveal that uncertainty is not only external—linked to geopolitics—but also internal to the institutions themselves. No clear consensus emerges on the future economic trajectory, making each monetary policy meeting potentially decisive for the coming months.

Financial Markets: The End of the Rapid Rate Cut Scenario

The accumulation of supply shocks, with the Middle East oil shock being the most significant event, has forced investors to deeply revise their expectations for monetary policy. Until recently, some segments of the market were factoring in a scenario of multiple Fed rate cuts throughout 2026. This scenario has now largely been abandoned.

The reasoning is straightforward: if inflation remains more persistent than anticipated due to sustainably high energy prices, central banks have no leeway to ease their policy. Interest rate markets are now factoring in a prolonged plateau, or even the possibility that the rate-cutting cycle will be more limited than expected. This reassessment is not limited to the Fed. The stance of the Bank of Japan, which is resisting pressure from its members who favor a rate hike, also supports the notion of a globally constrained interest rate environment.

This revision of expectations has tangible repercussions. Global financing conditions remain tight, putting pressure on both sovereign and private borrowers. Bond yields reflect this new reality: the market is pricing in a world where central banks are trapped by conflicting forces, between a slowdown that calls for flexibility and imported inflation that prevents it.

A Forced Stagnation Reshaping the Global Monetary Landscape

The combination of a major oil supply shock and contradictory economic signals places the Fed and the BoJ in a historically uncomfortable situation. The lack of monetary movement is not a result of institutional calm but an inability to make decisive moves in the face of symmetrical risks. Acting too soon in either direction could exacerbate the imbalance.

The internal disagreements observed within both institutions highlight this stalemate. They signal to the markets that the next decision—either upward or downward—could happen suddenly if the oil shock intensifies or if economic data shifts. This mechanically increases the potential volatility surrounding the upcoming monetary policy meetings.

The Middle East, a physical nerve center for oil, thus becomes a symbolic gateway for global monetary policy. As long as geopolitical uncertainty persists in this region, major central banks will continue to face this structural dilemma: protect growth or contain inflation, without being able to do both simultaneously. It is this unresolved tension that defines the current monetary horizon and shapes market participants' strategies for the coming quarters.
