BofA flags 9.5 bull-bear reading, Japan bank stocks as crash canary

Bank of America's sentiment gauge has flashed a sell signal for weeks, and its top strategist says Japan bank stocks will be the first domino to fall.

Bank of America's Bull & Bear Indicator held at 9.5 for a third consecutive week, a level that has preceded equity drawdowns of 2% to 3% on average and as much as 20% in extreme cases.

"Everyone is going all-in long, and that's exactly what makes us nervous," Michael Hartnett, chief investment strategist at Bank of America, said in the bank's latest Flow Show report.

Global equity funds attracted $56.6 billion in the week through July 8, the fourth-largest weekly inflow this year. Technology funds absorbed $18.8 billion, putting the sector on pace for a record $1.83 trillion in annual inflows. Money market funds swelled to $7.9 trillion, a fresh all-time high, showing investors are chasing risk while keeping record cash on the sidelines.

Hartnett identified Japan bank stocks as the "canary in the coal mine" for global risk assets. If Japanese government bond yields rise rapidly enough to pressure bank shares, the rotation out of equities could cascade across markets, he said.

The 'Four Wonts' Propping Up Markets

Hartnett distilled the market's consensus into four assumptions: the US economy won't hard land, the Federal Reserve won't raise rates, AI capital expenditure won't be cut, and Democrats won't sweep the midterm elections. Any one of these breaking could trigger a reversal, he said.

Hedge fund positioning sat at the 81st percentile, global equity fund flows at the 88th percentile and bond fund flows at the 84th percentile, according to the report. Fund manager cash allocation hit the 100th percentile — the most bullish reading possible. The only metric still neutral was global equity market breadth.

Global central banks have cut rates 34 times this year versus 21 hikes, backing the dovish tilt. The AI capex consensus calls for roughly $800 billion in 2026 and $1 trillion in 2027, underpinning tech valuations.

Japan as the Tipping Point

Japan's 10-year government bond yield has climbed from about 0.5% to nearly 3% over the past three years, lifting Japanese bank stocks roughly threefold over the same period — making them one of the best-performing cohorts globally. Hartnett said that if yields accelerate further and begin to weigh on bank shares, the shift would signal a broader risk-off turn.

The yen jumped Friday after Japan said it would push pension funds including the Government Pension Investment Fund to increase allocations to domestic assets. The currency strengthened from above 162 per dollar to an intraday high of 161.285, before settling at 161.70, up 0.4%. The euro and pound each fell about 0.3% against the yen, while the dollar index slipped 0.1% to 100.81.

"A shift in that would definitely create a lot more inflows for domestic assets," Fabien Yip, a market analyst at IG, said of the pension fund reallocation. "That's supportive of the currency and at the same time, also supportive of equities and bonds."

Scenarios for a Reversal

If the US economy cools, long-duration Treasuries, defensive consumer stocks, high-dividend shares and mega-cap tech could outperform, Hartnett said. If the Fed is forced to hike — a scenario he noted has historical precedent when CPI and unemployment both sit near 4.2% — the dollar and yield-curve flattening trades would benefit.

A pullback in AI spending would hit semiconductor stocks hardest, with software platforms and large-cap tech relatively better positioned. Hartnett pointed to narrowing debt-financing capacity, deteriorating cash flow and ongoing layoffs at tech giants as potential triggers for an AI capex slowdown.

If Democrats sweep the midterms, markets would need to price in tighter fiscal policy, a weaker dollar and lower bond yields, he said.
