Equity funds lost $31.44bn in the week bitcoin ETFs took in $6.21m

In the week ended 18 September, US equity funds shed $31.44bn in a fourth straight week of redemptions. Over the same five days American spot bitcoin ETFs took in $6.21m. Those are the same days, and the outflow from equity funds is 5,063 times the size of the crypto inflow. That ratio is the beginning of the answer to what the week means.

The full board:

• Out: US equity funds minus $31.44bn, money market funds minus $58.87bn, municipal debt minus $1.81bn.
• In: short-to-intermediate Treasury funds plus $3.49bn for an 11th straight week, sector funds plus $2.29bn, small-caps plus $568m.
• Crypto: bitcoin ETFs plus $6.21m, ether ETFs minus $140.0m.

The equity fund outflows are only part of the movement. Add the exits and $92.94bn left four categories. Add the entries and $6.91bn arrived in five. The visible inflow columns account for 7.4% of the money that walked, which means the bulk of it went somewhere the weekly tables do not show: individual securities, foreign funds, or simply out of the reporting perimeter. Anyone telling you where that $86bn went is guessing.

What the week was not

What the week was not is risk-off. Money market funds lost $58.87bn, the largest weekly withdrawal since 15 July, and cash leaving cash is the opposite of hiding in it. Sector funds took their biggest week in seven, led by financials at $1.37bn, with consumer discretionary and technology behind them. Small-caps gained while large-caps lost $28.71bn, which is rotation inside equities rather than an exit from them.

“I could see crypto and broader equities mounting a rally post-FOMC that could take bitcoin to a higher level than today into late September, early October.”

The 25 basis point increase is the event behind all of it, and the eleventh consecutive week of buying in short-dated Treasury funds is the cleanest read on how investors are positioned for it. Short duration is where you sit when you expect rates to stay put or rise again, not when you expect relief.

Where crypto actually sat

Crypto's place in the week is worth stating precisely, because it is neither of the roles it usually gets assigned. The bitcoin funds' $6.21m is 0.0061% of their $102.53bn in assets. They were not the destination for money leaving equities, and they were not a casualty of the hike either. They sat still while their asset base grew $4.95bn on price alone.

That is what the flows say. Bitcoin's 43.4% recovery from its July low is being carried by the people already holding it rather than by new money arriving, and the same is now visible in equities from the other direction: money is leaving the biggest funds without a visible place to land. Both facts sit inside the four tests we ran on whether the winter is over, and both answer the same way. Price has moved. Allocation has not.
