During an energy supply shock, central banks are trapped. Hiking rates doesn't increase oil supply and often causes a recession, leading to a policy reversal within a year. Conversely, stimulating the economy fuels demand into a supply-constrained market, worsening inflation. There is no easy path forward.

A spike in oil prices could keep CPI inflation above 3%. In this environment, the Fed cannot cut rates to support a weakening economy, as doing so would spook bond traders, risk higher long-term rates, and make financial conditions even tighter, effectively taking them 'off the table.'
Historical precedent is unequivocal: central banks do not cut interest rates in response to an oil shock. Despite the negative growth impact, their primary concern is preventing the initial price spike from embedding into long-term inflation expectations. Market hopes for easing are contrary to all historical data.
Current central banking models are designed for demand management (neo-Keynesianism) and are ineffective against structural supply shocks like the Hormuz crisis. Institutions like the Fed lack the tools and intellectual framework to respond appropriately, like 'a fish understanding a bicycle'.
Central bankers are caught in a tug-of-war. The slow reaction to the 2022 energy shock taught them to act decisively against inflation by raising rates. However, intense political pressure may push them to keep rates low, creating a difficult choice between applying learned economic prudence and ensuring political survival.
The market is pricing in aggressive Bank of England rate hikes in response to an oil price shock, expecting a repeat of 2022. This view is flawed because, unlike 2022, there is little scope for fiscal stimulus to protect the economy. An inflationary shock would likely trigger a recession, limiting the central bank to only two hikes, far fewer than markets anticipate.
The Federal Reserve cannot print oil. Therefore, during a supply-side commodity crisis, any major policy intervention will originate from fiscal authorities (e.g., the White House), not from monetary policy, which would only exacerbate inflation.
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.
An oil supply shock initially appears hawkishly inflationary, prompting central banks to hold or raise rates. However, once prices cross a critical threshold (e.g., >$100/barrel), it triggers severe demand destruction and recession, forcing a rapid policy reversal towards aggressive rate cuts.
When oil prices spike, they create widespread inflation. This prevents the Fed from using its primary tool—cutting interest rates—to help a struggling economy, as doing so would risk runaway inflation. The Fed is effectively caged until oil prices fall, leaving the market without its usual safety net.
