The call
Conditionally short EUR/USD if euro-area data weakens the near-certain ECB hike and US data keeps a Fed hike live.
What was priced
The starting line matters.
- ECB, 10 September
- 96.6%chance of a 25bp hike in swap pricing
- Fed, 16 September
- 57.5%chance of a 25bp hike after Jackson Hole
- Euro-area August HICP
- 3.0%headline consensus; 2.6% core
- US August payrolls
- 55–60ksurvey range; 4.2% unemployment expected

The thesis
Do not predict every release. Watch which expectation can move.
The euro already carries a strong presumption that the ECB will hike. Merely confirming that view may add little. A softer inflation mix, especially in core or services, could instead remove part of that support.
On the US side, Chair Warsh described inflation as too high and the labour market as stable. A resilient jobs or activity print could move a still-divided market towards a Fed hike. Either repricing would tend to widen the relative two-year rate outlook in the dollar’s favour.
Transmission
The view in one line.
or firmer US data→ECB odds fall
or Fed odds rise→Relative short rates
favour the dollar→EUR/USD lower
Catalysts
A sequence, not one heroic forecast.
German inflationFirst read on whether Europe’s energy shock is broadening.
Euro-area inflation; US ISM and JOLTSThe cleanest first comparison of European prices and US activity.
ADP, claims, services and payrollsTests whether the US labour market is merely slow or actually weakening.
ECB decision; US producer and consumer pricesThe thesis meets policy and the final major US inflation evidence.
Federal Reserve decisionThe end of this research window, not an excuse to rewrite the original call.
Decision rule
What would support or kill it.
Euro core or services inflation undershoots expectations, or US employment/activity beats expectations, and the relative two-year rate spread moves with the surprise.
The releases split, policy odds barely change, or EUR/USD moves without confirmation from rates. Keep the idea conditional.
Euro inflation stays broad and sticky while US labour or inflation weakens enough to reduce Fed hike pricing. The relative-rate mechanism points the wrong way.
Expression and risk
Why EUR/USD, and what can overwhelm it.
EUR/USD is the direct expression because the disagreement concerns the relative ECB and Fed policy paths. The strongest counterargument is that both hikes are already partly reflected and the exchange rate may respond more to energy, risk sentiment or positioning than to a small change in policy odds.
No entry level or position is recorded yet. Publishing the conditions first prevents a later move from being mistaken for a pre-existing thesis.
Dated updates
Initial view recorded. Awaiting the European inflation sequence and US labour/activity data. Status remains conditional.
