Is the Crypto Bull Market Back in September? Top Signals to Watch

After months of consolidation, the crypto markets are reviving with strong bullish action. Bitcoin has pushed back above $80,000, forming a local high of $82,000, while more than $132 billion has been added to the crypto market cap in the past 24 hours.  Besides, the Ethereum price also reclaimed $2500 as crypto ETFs recorded a significant jump in net inflows, which has been a source of buying pressure. 

The major catalyst driving the rally is the FED Governor Christopher Waller’s remarks on interest rates, which remained unchanged in September, provided the incoming inflation data improves. Bitcoin’s recent move is encouraging, but a strong rally alone does not confirm the beginning of a new bull market. Here are the seven signals that could determine whether the latest recovery could become a genuine bull market or it’s just a temporary rally. 

Bitcoin Reclaims a Critical Technical Zone

After falling sharply earlier in 2026,  the BTC price staged an impressive recovery in August, closing the month close to $80,000. The price surged over 25% and faced a small pullback that failed to last long. The token climbed back to $82,000 from the consolidation zone around $77,500, putting one of the most awaited resistance levels back in focus. 

 Bulls have been heading toward the $82,000 to $83,000 resistance range, and holding these levels could confirm the current rally. Conversely, if the price fails to do so, investors may conclude that the rally is running out of fuel, exposing the rally to the support around $72,000. Collectively, the price doesn’t need to explode but needs to prove that buyers are willing to defend higher prices. 

Where the ETF Money Goes Next

Spot Bitcoin ETFs have turned Bitcoin into a much easier asset for traditional investors to access. Instead of dealing with exchanges and wallets, investors gain exposure through familiar financial products and hence the money flowing here matters. In August, the spot BTC ETF experienced their strongest month since July 2025, with $3.52 billion in net inflows, driven by a 25% surge in BTC price. 

However, in the first few days of the month, outflows were also recorded along with inflows, which has made traders cautious. A sustainable crypto bull market needs persistent demand, and if the ETF inflows continue to weaken while prices hold high, it may not build a bullish case for Bitcoin and the whole market. 

Ethereum Could Tell Us Where the Rally is Spreading

Bitcoin is usually where institutional money goes first, and Ethereum provides a clue on the next movement. In August, ETH ETFs attracted significant capital, and their momentum continued into the beginning of September. ETFs recorded 12 consecutive trading days of inflows before registering nearly $48 million in outflows earlier this month. Besides, Ethereum has also been outperforming Bitcoin, and the ETH/BTC ratio is worth watching. 

The ETH/BTC has been consistently forming lower highs and lows, indicating the second-largest token is losing ground against Bitcoin. If ETH/BTC continues to drop, the market may still be operational in a more cautious way in Bitcoin-first mode. Hence, a stronger Ethereum is potentially a sign of improving risk appetite across the markets. 

The Federal Reserve Could Make or Break the September Rally

The Federal Reserve does not set the Bitcoin price, but its policies have been deeply impacting the rally. When investors expect interest rates to stay high, money tends to become more expensive and risk appetite can weaken. When markets start expecting lower rates, liquidity conditions can improve and speculative assets like crypto benefit. 

This is why the BTC price reacted aggressively to the recent comments from FED Governor Christopher Waller. Earlier, concerns about a potential September rate hike had contributed to the crypto sell-off. Waller indicated that he could support keeping rates unchanged if inflation continues to cool. But here’s a catch: the Fed hasn’t promised a rate cut, nor has it ruled out a hike either. Therefore, the September inflation report will be extremely important, along with the employment data and the Fed’s September 15 to 16 meeting. 

So, Is the Crypto Bull Market Back?

The Bitcoin price has recovered above $81,000. August produced strong Bitcoin ETF inflows, while Ethereum has shown improving momentum. With this, the market is becoming increasingly sensitive to the possibility of a less restrictive Federal Reserve. However, the biggest signal could be when the BTC price needs to deal with the $82,000 to $83,000 resistance area. 

In the meantime, ETF demand needs to remain consistent, and Ethereum and other cryptos also need to participate. If Bitcoin manages to break above the resistance with positive ETF inflows, the crypto bull market may gain pace. Besides, a failure could trigger a short-term correction to $72,000 or below. However, if the Fed remains uncertain and investors wait for cleaner economic data, BTC price may remain trapped between $76,000 and $83,000.
