Crypto Fear & Greed Index — September 2026: 55.5

In September 2026, the Crypto Fear & Greed Index averaged 55.5, starting near its high of 61 early in the month before dipping to a low of 51 on September 15. Tension was pushed up by news of US sanctions on an Iranian financier's crypto exchange, security reports showing platforms lost over $3.63 billion to cyberattacks, and concerns around four-year cycle declines. Market anxiety was further fueled as a Senate vote on the Clarity Act failed and lobbying efforts intensified. On the other hand, positive developments helped calm the mood, including Robinhood striking a deal with Crypto.com and a major drop in the estimated threat of quantum attacks against Bitcoin and Ethereum. Ultimately, the market balanced these mixed signals to finish the month at a relatively neutral level.
