"The lesson from 2022: do not use interest rates for the ECB as your guide for evaluation of the currency."

Cautioning against using ECB rate hike expectations as a primary driver of EUR/USD valuation. Correlation breaks down between rates and currencies in various stages, and anchoring on the ECB implies deep systemic flaws.

You are right to be cautious: using ECB hike expectations as your main valuation anchor for EUR/USD is a fragile framework, and 2022 is a textbook example of why.[6][1]

Why the rates–FX link broke in 2022

Even though rate differentials matter over the medium term, in 2022 the usual correlation between “more ECB hikes → stronger EUR” repeatedly failed because other forces dominated:[9]

The Three Overpowering Forces
Energy & Terms of Trade
Europe suffered a huge negative terms‑of‑trade shock from gas and power prices, mechanically weakening the euro.
🛡️
Safe‑Haven Flows
Global risk‑off episodes drove flows into the USD, overpowering any marginal improvement in euro carry.
📉
Growth & Fragmentation
Markets doubted the Eurozone’s ability to absorb higher rates without recession or peripheral stress.

So, simply saying “ECB is repricing more hawkish, therefore EUR should go up” led to poor FX calls, because it ignored why the ECB was being forced to hike and what the hikes implied for growth and risk premia.[10][4]

Why “ECB hikes = buy EUR” is a bad stand‑alone rule

When you anchor your EUR/USD view primarily on ECB policy expectations, you implicitly assume several conditions. None of these held consistently in 2022, and they often don’t in late‑cycle environments:

Assumptions vs. Reality in Late‑Cycle
Assumption
What Actually Happens
Reality
Rate differential is dominant driver
Fed tightening and US growth keep USD firm even as pure rate gap shifts.
Breaks Down
Hikes are a positive signal
Hikes into a recessionary backdrop trigger wider credit spreads and cut expectations.
Breaks Down
Risk premia follow rate expectations
Idiosyncratic risks (energy, politics) cause investors to demand higher risk premia.
Breaks Down

A better way to integrate ECB into a EUR/USD framework

Instead of treating ECB hike expectations as a directional signal on their own, treat them as just one input in a broader structure:

"All else equal, a hawkish repricing of the ECB should support EUR — unless it is driven by stagflation risk, amplifies fragmentation concerns, or is overwhelmed by a stronger Fed/safe‑haven USD bid." A Conditional Framework
