01

Read both policy stories

Begin with the euro-area inflation and policy assessment, then make a separate US assessment. A move in EUR/USD can reflect changes on either side. Describing an ECB development without considering the Fed may identify one relevant fact while leaving the relative comparison incomplete.

02

Match the measures before comparing

Euro-area HICP, US CPI and US PCE are not interchangeable indexes. Their methods and role in policy differ. Compare a like-for-like horizon where possible, then explain any remaining differences. A numerical gap without definitions is a weak foundation for a claim about relative inflation pressure.

03

Turn the narrative into a sequence

A useful note identifies the new information, the proposed effect on relative expectations and the observed change over a defined period. If one link is assumed rather than observed, say so. This makes it possible to revise the explanation when more evidence appears.

HYPOTHETICAL / A THOUGHT EXPERIMENT

Direction in plain units

At the hypothetical rate shown, €100 is priced at US$110 before costs. If EUR/USD rises to 1.1200, the same €100 is priced at US$112. The euro has strengthened against the dollar in this comparison; the arithmetic alone does not identify the cause.
