It may be the most wonderful time of the fear, but foreign exchange markets remain remarkably calm. 1-month implied volatility – a measure of expected swings in exchange rates – in G7 currency pairs is holding almost a full standard deviation below post-2000 norms, and remains well below comparable indicators in other asset classes.

We doubt this can be sustained as geopolitical risks simmer, outcomes diverge across the major economic blocs, and stress grows on the global financial system. We’d try to remind market participants of the ghosts of previous foreign exchange shocks – major moves tend to occur just when currency hedgers expect them least – but we’re just too old for this sheet.
