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.

Emerging market monetary policy is diverging significantly. Markets now price in rate hikes for low-yielding countries like Colombia, Korea, and Czechia due to stalled disinflation. In contrast, high-yielding markets continue to offer attractive yield compression opportunities, representing the primary focus for investors in the space.

The firm's analysts anticipate persistent core inflation in select emerging markets, suggesting an end to easing cycles. This contrasts sharply with clients who expect further disinflation driven by pressures from China and energy prices, marking a key area of disagreement on the global economic outlook.

Current oil prices are stuck in a dangerous middle ground. They fuel inflation across the economy but aren't high enough to trigger the demand destruction that would force central banks into decisive action, creating a prolonged inflationary environment.

Recent increases in emerging market rates are accompanied by flattening or stable long-end yield curves. This suggests markets are pricing in central bank rate hikes to control inflation, rather than reacting to worsening fiscal concerns, which would typically cause the curve to steepen.

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.

A significant shift is occurring where EM central banks, like in South Africa and Korea, are turning hawkish pre-emptively to combat inflation. This is happening even without the typical trigger of currency depreciation, indicating a proactive policy response to the inflation-growth mix rather than a reactive move to provide risk premia for a weakening currency.
