Three central banks moved inside three days. The Federal Reserve raised its policy rate on Wednesday, the Bank of Japan raised its own this morning to the highest level in about thirty-one years, and the Bank of England held with three of its nine members voting to go up.

Bitcoin is $77,708 this morning and up 1.72% on the day. Ether is up 1.96%. Solana is up 5.82%, and the more speculative the asset, the better its day has been.

Look at how the votes fell and it gets harder still. The Fed went twelve to nothing. The Bank of Japan went seven to two. Andrew Bailey's committee held six to three with the dissenters wanting a rise, and British money markets have since gone on to price as many as four increases in 2027, a path the Governor says his own committee never discussed. There is not a seat anywhere in that picture arguing for looser policy.

Everybody spent yesterday explaining those green numbers away. Crypto has broken its link to interest rates, or the tightening was already in the price, or the hikes are the good kind because the labor market is strong. Pick one.

All three explanations rest on the same assumption. They take the policy rate to be the thing crypto trades on: raise the rate, and anything whose payoff sits years out is worth less today, because you can now earn more for doing nothing. That reasoning is correct as far as it goes, and it covers half the picture.

Here's the other half. A central bank sets the price of borrowing a dollar. It does not directly set how many dollars are out there to be borrowed, and the second number is the one that fills or empties a market in risky things. This month the two of them went in opposite directions.

Normally they don't, which is why almost nobody bothers watching both. The usual way a central bank makes money dearer is by taking some of it out of circulation, so the price goes up because the supply went down. Watch one and you have effectively watched the other, and for most of the last two years that shortcut worked.

It stopped working this month, for reasons that have nothing to do with crypto and everything to do with how the American government funds itself. The Treasury's cash balance and the money parked overnight at the Fed both move on their own schedule, and when they empty out they put dollars back into the hands of people who can lend them, whatever the policy rate is doing.

We count what's left once a week, and it turned two weeks ago.
