A rate increase can therefore coexist with a rally, especially when buying strengthens, and traders closing bearish positions add to the pressure.
September 2026 provided an example. The US Federal Reserve raised its policy rate by a quarter of a percentage point on 16 September. Five days later, Bitcoin rose above $86,000 as oil prices and bond yields eased, according to Associated Press. Crypto was recovering while the higher policy rate remained in place.
On 22 September, AlphaWire reported that the crypto rebound had spread across Bitcoin, Ether, Solana, and XRP. Those gains across major cryptocurrencies show why a rate decision alone cannot explain the market’s direction: the conditions affecting trading can change, even when the central bank has made no further move.
Why higher rates can weigh on crypto
Interest rates influence the cost of borrowing and the appeal of holding money in interest-bearing assets. Higher financing costs can make traders more reluctant to borrow for speculative positions. Better returns elsewhere can also make holding a volatile cryptocurrency less attractive by comparison.
Bitcoin itself pays no interest simply for being held. Its price depends on what people will pay for it, rather than a contractual stream of payments. Changes in appetite for risk can consequently affect demand, although they do not provide a formula for predicting the next price move.
The US central bank’s decisions are relevant beyond America because crypto trades internationally and dollar financing conditions affect global markets. For British readers, a Bitcoin headline quoted in dollars describes that dollar price, and doesn’t explain anything about the effect on sterling.
Markets react before the announcement
The date of a rate decision is not necessarily the date when its consequences first reach prices. Traders adjust positions as inflation figures, economic releases, and central bankers’ comments alter expectations. By the time the announcement is made, some of the response may already have happened.
Expectations were already shifting before September’s decision. In commentary published on 3 September, Coinbase’s institutional research team described a rate increase as being priced into markets. That was an assessment made before the meeting, rather than proof of how every trader was positioned. It nevertheless documents that the possibility of higher rates was influencing the discussion well before announcement day.
The distinction is between the level of rates and new information about them. A high rate can remain a constraint while a change in expectations gives prices room to recover. The statement accompanying a decision can also change views about how long rates will stay elevated.
Short covering can accelerate a rally
Crypto prices also respond to positions already sitting in the market. A short position benefits when prices fall. When prices rise instead, closing that position can require a purchase, adding buying pressure to an upward move.
In futures markets, traders close a short by buying the corresponding contract. This does not necessarily mean buying and taking ownership of Bitcoin itself. It can simply mean ending exposure to a price decline. A purchase therefore need not represent someone becoming enthusiastic about crypto’s longer-term prospects.
Leverage makes the reaction sharper. It allows a position to be larger than the collateral supporting it, so an adverse price move can quickly exhaust the required cushion. An exchange may then forcibly close the position, a process called liquidation.
When rising prices trigger the closure of shorts, the resulting purchases can push prices higher and put further shorts under pressure. This feedback is known as a short squeeze. It can amplify a rally, but it cannot establish how long the rally will last. Once those positions have closed, that particular source of buying is spent.
Buying beyond the squeeze
There was evidence of more than position closures during September’s recovery. In its 21 September report, Glassnode described stronger spot buying alongside a wave of short liquidations. It found that exchange activity had shifted towards buying, with trading volume also increasing.
Spot trading involves the cryptocurrency itself, rather than a futures contract tied to its price. Evidence of spot demand adds information that liquidation totals alone cannot provide. It suggests the rebound was not explained entirely by traders being forced out of bearish positions.
That still leaves limits. Trading activity does not reveal every buyer’s motives or intended holding period. Evidence from one rally cannot turn higher rates into a positive signal for crypto, and simultaneous movements do not establish a single cause.
Reading the rate announcement alongside spot demand and position closures gives a fuller explanation. Rates shape the backdrop; buying and selling determine the price at which trades happen. A rebound after a rate increase is evidence that several forces were operating together, rather than proof that borrowing costs had stopped having an influence.
