Fed Raises Rates to 3.75%-4%: What the First Hike Since 2023 Means for Bitcoin and Crypto Liquidity

The Federal Reserve’s first interest-rate increase since July 2023 landed with little immediate disruption in the two largest crypto assets. Bitcoin traded roughly between $75,000 and $76,500 around the September 16 decision and was near $75,600 when reported, while Ether moved between about $2,370 and $2,430. That contained response suggests the quarter-point move itself was largely expected.

For crypto, the issue is less the marginal tightening from the previous setting to a target range of 3.75% to 4.00% than the prospect of operating with a persistently higher cost of capital. Long-dated Treasury yields now offer returns that compete directly with speculative positioning. Yet the Fed has also instructed the New York Fed to buy Treasury bills as appropriate to maintain ample reserves. The result is a tension between higher rates and reserve management that complicates the simple “Fed tightening equals less crypto liquidity” reading.

A 25-basis-point hike that Bitcoin had already absorbed

The Federal Open Market Committee unanimously raised the federal-funds target range by 25 basis points on September 16, to 3.75%-4.00%. In its policy statement, the Fed said economic activity had been expanding solidly, job gains had kept pace with workforce growth and inflation remained elevated.

The decision marked the first increase since July 2023, a fact that could have made it a conspicuous risk event for an asset class often sensitive to shifts in dollar funding conditions and investor appetite. Yet the price ranges reported by The Block point to adjustment rather than disorder. Bitcoin and Ether both moved, but neither showed an outsized directional break in the immediate aftermath.

That does not mean monetary policy has become irrelevant to crypto. It means the headline action was only one part of the decision. A 25-basis-point adjustment that is already widely anticipated can leave market attention on the path beyond the meeting: the expected level of rates, the return available in conventional assets, the availability of leverage and the condition of the financial system’s liquidity plumbing.

For holders of Bitcoin and Ether, the distinction matters. Spot-price stability on decision day can coexist with a tougher medium-term setting for assets that do not provide contractual income. The relevant comparison is not only yesterday’s policy rate against today’s. It is also the return investors can earn across the Treasury curve and the duration for which they expect those returns to remain elevated.

Fed projections move the issue to higher-for-longer

The September Summary of Economic Projections put the median federal-funds rate at 4.1% at the end of 2026 and 4.1% at the end of 2027. The June medians were 3.8% and 3.6%.

The same projections raised the median 2026 PCE-inflation forecast to 3.7% from 3.6% and the core-PCE forecast to 3.4% from 3.3%. They lifted the GDP-growth forecast to 2.3% from 2.2% and lowered the unemployment forecast to 4.1% from 4.3%.

Those figures combine firmer projected inflation with stronger projected growth and lower projected unemployment. They therefore complicate the view that tighter policy must soon give way to relief because of looming economic weakness.

The projections are policymakers’ assessments rather than a fixed commitment about future meetings, but the higher path still makes a higher-for-longer interpretation more relevant to crypto markets than treating the rate increase as a one-off adjustment. Investors may face a less accommodating backdrop for portfolio allocation, financing decisions and risk-heavy exposures even without an immediate recession threat.

A 5.04% 10-year yield raises crypto’s carrying cost

The sharpest competing signal came from the Treasury market. The 10-year Treasury yield reached 5.04%, its highest level since 2007, according to Axios reporting on the Fed decision. The level matters because it extends the comparison facing crypto investors beyond overnight or short-term cash returns.

Bitcoin and Ether may be held for many reasons, including expectations of price appreciation, use within digital-asset markets and diversification. Neither, however, carries the contractual yield of a Treasury security. When long-term government yields rise, the opportunity cost of allocating capital to a non-yielding asset rises as well. That comparison can be especially important for capital that is not committed to a long-term crypto thesis and can shift between liquid markets.

The effect can also run through leverage. Higher risk-free rates raise the baseline cost against which borrowing and speculative trades are evaluated. This does not establish that every crypto position will be reduced, nor does a 5.04% 10-year yield mechanically determine Bitcoin’s price. Digital assets have their own flows, market structure and idiosyncratic catalysts. But the yield level creates a meaningful headwind for the broad liquidity conditions in which highly speculative exposures tend to be financed.

That is why Bitcoin’s muted initial response should not be mistaken for a complete verdict on the decision. Markets can absorb a known rate move while reassessing how much return must be offered elsewhere to justify taking crypto risk. The combination of a 3.75%-4.00% policy range and a 5.04% 10-year yield leaves little room for the argument that investors are being pushed out of conventional fixed income by negligible returns.

It also places more weight on whether crypto can attract fresh demand on its own terms. In a low-yield environment, the absence of income may be less central to allocation decisions. In an environment where long-dated Treasuries offer more than 5%, prospective returns, volatility tolerance and liquidity needs become harder to separate from that alternative.

Treasury-bill purchases complicate the crypto-liquidity verdict

The Fed raised the interest rate on reserve balances to 3.90%, the standing overnight repo rate to 4.00% and the primary credit rate to 4.00%. At the same time, its implementation directive instructed the New York Fed to purchase Treasury bills when appropriate to maintain ample reserves.

Those purchases are for reserve management. They do not show that the Fed is reversing its higher-rate stance or launching broad stimulus, but they do mean that a rate increase does not automatically amount to an aggressive drain of banking-system reserves. The Fed’s projected policy-rate path is also higher than it was in June, supporting a higher-for-longer interpretation rather than a one-off adjustment.

That leaves two distinct questions for crypto: the price of money and the quantity and functioning of bank reserves. Treasury-bill purchases address the latter, not the former. They may weaken the case for assuming an immediate, mechanical liquidity squeeze from the September hike, while leaving intact the higher opportunity cost of holding non-yielding crypto assets, particularly with the 10-year Treasury yield at 5.04%.
