The European Central Bank's rate-hiking cycle is unlikely to be as long as markets expect. Unlike in 2022, the ECB isn't starting from deeply negative rates, reducing the need for an aggressive "catch-up" cycle. Risks are skewed towards fewer hikes than the 70-75 basis points currently priced by the market.

Contrary to typical FX reactions, hawkish ECB policy amid an energy shock would be profoundly negative for growth. Any rate hikes would compound the economic damage from higher energy prices, making the Euro more vulnerable.

Any strength in the Euro from a hawkish European Central Bank is unlikely to last. The Eurozone's weak fundamentals—lagging growth, poor equity returns versus the US, and energy price vulnerability—mean that higher interest rates would further stifle the economy, making any rate-driven rally unsustainable and positioning the Euro as a funding currency.

Markets pricing in ECB rate hikes after an energy shock is flawed. Higher energy prices are a negative growth impulse for Europe, hurting terms of trade and consumer spending. Hiking rates would only worsen the downturn, making European cyclicals and the Euro vulnerable regardless of policy.

The Federal Reserve focuses on growth risks from an oil shock as the US services-based economy sees less impact on core inflation. In contrast, the European Central Bank is more likely to raise rates, prioritizing inflation control due to faster price pass-through in the euro area.

While initial energy price spikes boost short-term inflation expectations, a sustained shock eventually hurts economic growth. This growth concern acts as a natural ceiling on long-term inflation expectations (break-evens), as markets anticipate an economic slowdown, preventing them from rising indefinitely.

Single-mandate central banks like the ECB and BoE are trapped. They must react to oil-driven inflation with hawkish policy, even though their economies are most exposed to the energy shock's demand destruction, creating a stagflationary double whammy.

Policymakers, scarred by post-COVID inflation, risk tightening monetary policy excessively in response to energy price surges. History suggests these shocks are temporary and primarily affect headline, not core, inflation. The greater danger is stifling economic growth by overreacting to a transient inflationary impulse.

Unlike the US Fed, the European Central Bank is expected to raise interest rates in response to the energy shock. This is because its single mandate focuses purely on inflation, and Europe historically experiences stronger 'second-round effects' where energy prices lead to broader wage increases.
