Bitcoin Heads to the September FOMC: Will the BTC Rally Stop?

Bitcoin entered September with sentiment not yet fully stable.

After recording a recovery in late August, market attention shifted to the September 2026 FOMC meeting scheduled for September 15–16, especially as the Federal Reserve's track record of decisions throughout the year suggests Bitcoin's response is likely to be negative.

The FOMC is important because the Fed's interest rate policy affects liquidity, bond yields, the US dollar, and investor appetite for risky assets.

For Bitcoin, changes in interest rate expectations could determine whether the BTC rally continues or turns into a bearish market squeeze.al.

Key Takeaways

• The September 2026 FOMC takes place on September 15–16tember and became one of the biggest macro catalysts for Bitcoin.

• Three of the five FOMC decision days in 2026 so far have been bearish pivots for BTC, while spot Bitcoin ETFs have also recorded outflows in most of the decisions.

• There is a 65.2% chance of maintaining the interest rate at 3.50%–3.75%, but the risk of interest rate increases remains.

Why is the September FOMC Important for Bitcoin?

The Federal Open Market Committee or FOMC is a Federal Reserve committee that determines the direction of United States monetary policy.

These decisions include whether interest rates are raised, lowered, or maintained.

For Bitcoin, interest rates are closely linked to liquidity. High interest rates increase the cost of capital and typically reduce interest in risky assets like crypto.

Conversely, interest rate cuts can increase the attractiveness of risky assets due to looser financing conditions. Besides interest rates, the market is also paying attention to quantitative tightening (QT).

When the Fed reduces the size of its balance sheet, the liquidity of the financial system may also decrease.

This situation poses a challenge for assets like Bitcoin, which require capital inflows and risk appetite to maintain a bullish trend.

Bitcoin's 2026 FOMC Track Record Tends to Be Bearish

One of the reasons the market is starting to be wary of Bitcoin's September FOMC is the performanceBTC on interest rate decision days throughout 2026.

The Fed has maintained interest rates in the range of 3.50%–3.75% in five consecutive decisions.

However, seemingly identical decisions have resulted in different Bitcoin price responses.

Of the five decision days, January, March, and June were fairly clear bearish pivots.

April actually provided a bullish response after Jerome Powell signaled that the Fed did not want to tighten excessively, which could trigger a credit crunch.

Bitcoin then moved to around US$82,500 in May.

July was relatively indecisive. Bitcoin lacked any strong bullish catalysts, despite interest rates being held steady.

This condition shows that the market is not only reacting to interest rate figures, but also to the Fed's policy language and views on liquidity.

Bitcoin Selling Pressure Could Increase Again

Liquidation data shows how sensitive the crypto market is to FOMC decisions.

In January, following developments regarding the candidacy of Kevin Warsh as the Fed Chair nominee sparked concerns about monetary policy, Bitcoin fell about 7% from US$84,600 to US$78,700.

The move resulted in the liquidation of approximately US$2.407 billion in long positions in the crypto market, compared to US$154.7 million in short positions.

This figure remains one of the largest liquidation episodes in 2026.

This situation shows that the risk does not only come from the decline in BTC prices.

When derivatives markets are highly leveraged, small changes in Fed expectations can trigger chain liquidations and accelerate price movements.

Therefore, ahead of the Bitcoin FOMC, oPen interest and leverage levels are indicators that are as important as spot prices.

Bitcoin ETFs Also Signal Caution

Bitcoin spot ETF fund movements around the FOMC decision showed a pattern that was not particularly supportive of a rally.

Cited data shows that the 48-hour period surrounding the January decision recorded an outflow of US$837.4 million. March recorded an outflow of US$253.7 million, April US$114.1 million, and June US$172.9 million.

Only the July decision generated a net inflow, about US$265.2 million.

This means that in most 2026 FOMC decisions, ETF investors actually withdrew funds when the market faced monetary policy catalysts.

This pattern does not mean that ETFs will definitely record outflows in September.

However, investors need to pay attention to this data because institutional cash flows can act as a buffer when Bitcoin prices face pressure.

Fed Rate Could Be Maintained or Raised in September

FedWatch shows a 65.2% probability of maintaining rates at 3.50%–3.75%. Meanwhile, the probability of a 25 basis point increase to 3.75%–4.00% is at 34.8%.

Thus, the main market scenario is still similar to the Fed's fixed interest rate.

However, maintaining interest rates is not necessarily automatically bullish for Bitcoin.

Markets could react negatively if the Fed's statement suggests that high interest rates will persist for longer.

Even without a rate hike, rising long-term Treasury yields could tighten financial conditions and reduce the attractiveness of risky assets.

Treasury Yields Become an Additional Risk

The condition of US bonds is also a factor to watch ahead of the Fed's September decision.

In July, Darkfost analysts noted that the 10-year Treasury yield reached 4.7%, while the 30-year yield was above 5.2%. These levels were described as the highest since 2007.

High yields increase the opportunity cost of holding zero-yielding assets like Bitcoin.

Investors can obtain higher returns from bond instruments with different risks.

If yields continue to rise while the Fed remains hawkish, liquidity could tighten further. This situation could potentially become a hindrance for Bitcoin rally even though the benchmark interest rate is not changed.

Could the BTC Rally Stop in September?

The risk of a correction does increase if the September FOMC produces a hawkish message. However, the Fed's decision isn't the only factor determining Bitcoin's direction.

If the Fed maintains interest rates while signaling a more dovish outlook for future policy, the market could interpret this as an opportunity for riskier assets.

Positive ETF fund flows could also strengthen the bullish response.

On the other hand, if the Fed emphasizes still-high inflation, the possibility of an interest rate hike, or the need to maintainIf the policy tightens for longer, Bitcoin selling pressure may increased again.

Therefore, Bitcoin September predictions should use two scenarios.

A bullish scenario requires improved liquidity and dovish signals, while a bearish scenario could emerge if yields continue to rise and policy expectations tighten.

September Will Be a Big Test for Bitcoin

The FOMC isn't the only important agenda item in September.

The US Senate is also scheduled to vote on the CLARITY Act on September 15, potentially exposing the crypto market to two major catalysts in close proximity.

The combination of monetary policy and regulation could increase Bitcoin volatility.

If positive regulatory sentiment meets a more dovish Fed policy, BTC will receive two catalysts.

Conversely, disappointing results from both agendas could increase market pressure.

This is why September 2026 has the potential to be a crucial month in determining the next direction of Bitcoin's price.

Conclusion

Bitcoin FOMC September is of concern as the 2026 track record shows three out of five interest rate decision days resulted in a bearish pivot for BTC.

Additionally, most of the decision periods were followed by Bitcoin spot ETF outflows.

The market is currently more likely to expect the Fed to maintain interest rates at 3.50%–3.75%.

However, if central banks signal a hawkish trend or Treasury yields rise again, the BTC rally could potentially lose momentum.

Conversely, dovish signals, improved liquidity, and positive ETF flows could open up space for Bitcoin to continue its recovery.

So, the main question is not just whether the Fed raises or holds rates.interest, but what was the Fed's message after the decision.
