Bitcoin Back Above $80,000 After Fed Hike and CLARITY Act Failure

Short answer: On Friday, September 18, 2026, bitcoin climbed back above $80,000, gaining roughly 5–6% in a day after opening near $76,350. The move came two days after the Federal Reserve raised rates for the first time since 2023 and three days after the CLARITY Act failed a procedural vote in the U.S. Senate. It was driven largely by liquidations of short positions and followed a return of spot bitcoin ETF inflows — about $159.5 million on September 17 after two days of heavy outflows. Crypto stocks rallied with it: Coinbase closed up around 11% and Strategy more than 11%.

What happened on September 18

Bitcoin opened Friday at about $76,350, according to Yahoo Finance data, and had already risen to roughly $78,000 by 7:25 a.m. ET. During the U.S. session the rally accelerated and the price pushed through $80,000, briefly trading above $81,000 at the intraday high. Market reports put the daily gain at around 5.5%, with some measures closer to 6%. Ethereum moved in the same direction, rising from about $2,445 at the open to above $2,500 in the morning.

The timing is notable because the week started badly for crypto. On Tuesday, September 15, the Senate cloture vote on the Digital Asset Market CLARITY Act fell well short of the 60 votes needed, and bitcoin slid below $75,000. On Wednesday, September 16, the Fed lifted its target range by 25 basis points to 3.75%–4.00%. Rather than extending the sell-off, the market treated the two events as known risks and started buying back. We covered both in detail: the CLARITY Act Senate vote and the Fed's September rate hike.

Why did bitcoin go up after a Fed rate hike?

Higher rates are usually a headwind for risk assets, so the rally looks counterintuitive. Three things explain most of it.

The news was already priced in. A 25 bp hike had been widely expected, and the CLARITY Act failure was visible for days before the vote. Once both were out of the way, the uncertainty that had kept buyers on the sidelines faded.
Positioning was one-sided. After the drop below $75,000, many traders had bet on further declines with leveraged short positions. When the price turned higher, those positions were forced closed, which meant buying — a classic short squeeze. Reports counted more than $445 million in liquidated shorts across the market.
ETF money came back. U.S. spot bitcoin ETFs lost roughly $450 million on September 15 and about $296 million on September 16, then swung back to a $159.5 million net inflow on September 17. For context on the earlier drain, see our note on bitcoin ETF outflows in September.

Other macro news helped the mood. Yahoo Finance pointed to the restoration of Saudi Arabia's East-West oil pipeline, which eased some inflation worries, and Coinbase CEO Brian Armstrong argued publicly that the industry still has a path forward through the SEC and CFTC even without new legislation.

Crypto stocks joined the move

Shares of crypto-linked companies outperformed bitcoin itself. Coinbase gained about 11% — reported closing prices vary slightly between sources — helped also by company news, including a filing to list more than 50 single-stock perpetual futures. Strategy, the largest corporate bitcoin holder, rose more than 11%. This kind of amplified reaction is typical: listed crypto companies tend to move more than the underlying asset in both directions.

Why it matters — and what it does not mean

The rebound shows how quickly sentiment in crypto can reverse once a cluster of known risks is resolved, even if the outcome was negative. It also underlines how much of the short-term price action comes from leverage and fund flows rather than from changes in fundamentals.

At the same time, the macro backdrop has not become friendlier. CoinShares, in its September 18 market update, described the Fed's message as firmly hawkish, noting that the dot plot removed expected easing through 2027, and said a decisive, lasting break above $80,000 would be difficult without better inflation data or a shift in policy expectations. In other words, one strong day does not settle the direction of the market. Bitcoin also remains well below its all-time high of about $126,000 set in October 2025.

What to do if you swap or hold crypto: a checklist

Expect wide swings in both directions. Days with large liquidations often bring sharp intraday reversals. If you plan to swap, avoid sending funds in the middle of a spike when rates at instant exchangers can move between quote and execution.
Compare rates before you swap. During fast markets the gap between services widens. Check several offers on the exchangers list and look at the final amount received, not the headline rate.
Prefer fixed-rate orders for large amounts. A floating rate can shift noticeably while your deposit confirms; a fixed rate removes that risk at a small cost.
Be careful with leverage. The same mechanism that lifted the price on September 18 wiped out hundreds of millions in positions. Leverage magnifies losses as well as gains.
Keep holdings you do not trade in self-custody. Volatile days are also when exchanges get congested and scams multiply; see our guide to self-custody wallet security.
