Here’s Why EUR/USD Is Not Trading Higher on the Fed Re-Pricing

The recent failure of two US banks, SVB and Signature, have understandably triggered a major re-appraisal of Fed tightening prospects. This has seen two-year EUR/USD swap rate differentials move to the narrowest levels since October 2021. One could expect EUR/USD to be trading substantially higher than this, but risk sentiment is likely holding it backh2 Market Is Close to Pricing the Fed Tightening Cycle as Over/h2

In a complete U-turn from its reaction to hawkish Powell testimony last week, markets today struggle to price one further 25bp hike from the Fed. This is a far cry from last week's +75-100bp of extra tightening. The re-pricing of the Fed is understandable as US authorities struggle to put a floor under the evolving banking crisis. Indeed, the KBW Regional Banking index is off another 10% today – not what authorities wanted to see after promising at the weekend to make all depositors whole and introducing new liquidity provisioning schemes.

This dramatic re-pricing of the Fed cycle has outpaced anything seen amongst European monetary cycles and delivered a huge narrowing in two-year EUR/USD swap differentials. Normally, rates at the short end of the curve are solid drivers of exchange rates (signifying the path of respective monetary policy).

The sharply narrower spread would be expected to drive EUR/USD a lot higher. EUR/USD has turned around from its 1.0525 lows seen last week, but what stops it from trading substantially through 1.08? We think a look at the key short-term drivers of EUR/USD provides the answers.

Our financial fair value model takes into account an array of market factors to estimate mis-valuation in FX in the short term. A closer look at the swings in the coefficients of the EUR/USD model helps us understand why the pair has been capped despite falling US rates.

In late 2021, the last time the two-year swap spread was as narrow as 80-90bp, EUR/USD was trading around 1.15. However, short-term rate differentials back then were the single most important driver of EUR/USD (chart below). At the same time, the coefficient of two-year swap spreads is now very close to zero, meaning that even a very large move in the spread statistically implies only a small move in EUR/USD. And this is exactly what we are observing now.
