Global inflation is discussed as a single trajectory that central banks are variously ahead of or behind. The aggregate is still falling; what matters for allocation is that the policy responses underneath it have stopped moving together.

The IMF projects global consumer-price inflation of 4.4% in 2026. The OECD separately projects aggregate G20 headline inflation of 4.0%, 1.2 percentage points above its previous expectation. These are not directly comparable measures - one is global, one is G20 - but they point the same way. What follows concerns the dispersion behind those aggregates.

The Country Distribution Is Not a Distribution Around a Mean

The IMF projects average consumer-price inflation of approximately 387% for Venezuela, 69% for Iran and 30% for Argentina in 2026. Turkish annual food inflation ran approximately 35% in May.

A 4.4% global figure containing observations at 387% is not describing a central tendency any portfolio can be positioned against. Argentina is stabilising but not out of its inflationary cycle, and the tail is doing most of the work in the aggregate.

The G10 Corridor Is Splitting, Not Lagging

New Federal Reserve Chair Kevin Warsh begins with US inflation above target, a resilient domestic economy, and market expectations that have moved sharply away from near-term easing. Rate cuts are no longer the assumed next step and renewed tightening has re-entered the discussion.

Europe faces a different configuration entirely. The ECB and the Bank of England must answer the same energy shock through economies with weaker growth and greater sensitivity to imported energy. The ECB has already tightened as insurance while euro-area growth remains subdued.

The distinction worth holding is that this is not one central bank ahead of another on a shared path. Same shock, different transmission, different constraint - which means the policy paths diverge rather than converge with a lag.

The Shock Arrived Into an Already-Stretched System

Inflation here is not only the original problem. It is part of the bill for the credit expansion that preceded it. A prolonged period of cheap money altered how capital was priced and allocated.

When a supply shock arrives in that environment it does not meet a clean system. It meets one already stretched by leverage, duration risk and compressed risk premia - which is why the same shock produces larger dispersion in outcomes than its size alone would suggest.

Dollar Strength Is Itself a Tightening

What attracts capital is no longer just a high policy rate. It is the broader US exceptionalism trade: positive real rates, a resilient domestic economy, expectations of technology-driven productivity growth.

For emerging-market central banks that is a second tightening channel operating independently of their own policy. It raises the domestic cost of imported goods and dollar liabilities, constrains room for easing, and can force currency defence even as domestic growth weakens.

What This Means for Allocators

Reprice the opportunity cost of waiting. Cash and short-duration instruments can again deliver a positive real return, which changes the hurdle every duration, credit and equity exposure must clear.

Stop treating G10 policy as one path with different start dates. Portfolios built on the assumption of synchronised easing are positioned against a corridor that is widening, not narrowing.

And require compensation rather than participation. Construction developed in the zero-rate period assumed idle liquidity carried a substantial cost. That assumption no longer holds in the same way - when waiting pays, risk must offer more than exposure.
