FX Signals Diverge As S&P 500 Rally Faces Key Resistance

The S&P 500 faces resistance at 7,450 as yen and won signals suggest a liquidity withdrawal.

The move in the markets today was somewhat surprising, given the size of the rally in a few names, along with what appeared to be intervention in the Japanese yen ahead of tonight’s BOJ meeting. Additionally, the Korean won continued to strengthen, despite it being a mild Treasury settlement day. Sometimes, however, news flow can be more powerful than mechanical flows, and today was one of those days.

The more interesting point, I suppose, is that the index has now been stuck below 7,450 since July 23, and that has remained the key level of resistance. At this point, a strong gap higher that clears resistance could lead to a rally back toward 7,500, ultimately filling the gap created by the decline on July 22.

One thing worth noting is that today’s rally created a gap of its own following yesterday’s sharp drawdown. In my view, those types of gaps are typically unstable and tend to fill relatively quickly.

Perhaps what matters just as much is that USD/JPY weakened materially today, in what appeared to be intervention, oddly ahead of tonight’s BOJ meeting. A surprise rate hike by the BOJ would likely be another shock to the market at this point and could lead to even further yen strength.

Since 2023, the 3-month implied correlation index and USD/JPY have been almost mirror images of one another. If that relationship continues to hold, it would suggest that implied correlation is poised to rise. That, in turn, would likely pressure dispersion lower and could weigh on the broader equity market.

Additionally, USD/KRW continued to weaken today as well, making the rally in the semiconductor sector somewhat unusual. No relationship lasts forever, but this has been a very strong signal over the past several weeks.

If the market has been largely driven by liquidity, and that liquidity is now being withdrawn, then the signal from the FX market does not support today’s move.
