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.

The market's hawkish repricing for the Bank of Canada is likely temporary due to underlying economic slack and trade risks. In contrast, Australia's RBA is a more credible potential hiker, supported by resilient growth and higher inflation, making it a "true soft landing candidate" and a better bet for policy tightening.

Despite the economic risks from higher oil prices, the Federal Reserve is unlikely to cut interest rates. The central bank is firmly focused on high pre-existing inflation and rising inflation expectations, and geopolitical uncertainty will likely cause them to hold policy steady rather than provide stimulus.

The narrative driving the AUD's strength—that the Reserve Bank of Australia is on a unique and aggressive hiking path—is becoming mature. The policy gap between the RBA and other G10 central banks is at an extreme level, suggesting the Aussie's outperformance could diminish as other banks begin their own tightening cycles.

A potential drop in oil prices may cool headline inflation, but it won't necessarily stop Emerging Market central banks from tightening. Underlying price pressures from sticky services inflation, strong demand, and supply bottlenecks will keep core inflation elevated, maintaining the bias towards further rate hikes.

Policymakers can maintain market stability as long as inflation volatility remains low, even if the absolute level is above target. A spike in CPI volatility is the true signal that breaks the system, forces a policy response, and makes long-term macro views suddenly relevant.

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.

The disinflationary impact from goods prices has largely run its course in emerging markets. The remaining inflation is concentrated in the service sector, which is sticky and less responsive to monetary policy. This structural shift means the broad rate-cutting cycle is nearing its end, as central banks have limited tools to address services inflation.
