Unlike emerging markets where pro-cyclical trades are crowded, positioning data shows the bearish US dollar view is not widely held in G10 currencies. This lack of a broad consensus short means there is less risk of a sharp deleveraging, giving pro-cyclical G10 FX more room to appreciate against the dollar.

The bullish case for the Euro is weakening as growth signals outside the U.S. lose intensity. Critically, all of J.P. Morgan's developed market economic activity surprise indices have now fallen into negative territory, posing a significant challenge to the Euro's cyclical strength against the dollar.

While the idea of US growth re-acceleration is driving dollar strength, it's not the only story. Recent positive surprises in European PMI data and upgraded Chinese GDP forecasts suggest broader global growth resilience. This breadth should help cap the US dollar's rally and may promote weakness against other currencies.

Despite a popular bearish narrative, the U.S. Dollar has a strong bullish case. The U.S. economy is accelerating while Europe and Japan face stagflation, and record short positioning creates fuel for a squeeze. The argument is that U.S. stocks are essentially levered U.S. dollars, and relative strength will attract capital.

Contrary to the historical norm where volatility rises with a strengthening dollar (risk-off), the market is now experiencing higher volatility as the dollar falls. This unusual 'dollar down, vol up' dynamic suggests a pro-cyclical market backdrop and has major ramifications for how FX options and risk reversals are priced.

Emerging vs. developed market outperformance typically runs in 7-10 year cycles. The current 14-year cycle of EM underperformance is historically long, suggesting markets are approaching a key inflection point driven by a weakening dollar, cheaper currencies, and accelerating earnings growth off a low base.

The Federal Reserve's dovish stance, combined with a resilient global growth outlook, creates a favorable environment for "pro-cyclical" currencies like the Australian Dollar and Norwegian Krone. This "middle of the dollar smile" scenario suggests betting on currencies sensitive to global economic momentum, not just betting against the dollar.

The classic "stocks down, dollar up" correlation is weakening. A J.P. Morgan model shows that relative US equity underperformance (dollar-negative) is currently offsetting the effect of an outright global equity decline (dollar-positive). This dynamic leads to only modest moves in the dollar despite stock market stress.

The current rotation out of US tech stocks should not be mistaken for a US growth problem. It is supported by better global growth prospects, strong relative earnings, and positive PMI data outside the US, which reinforces the case for pro-cyclical positioning in FX markets and other assets.
