According to The Kobeissi Letter, the S&P 500 has posted its strongest monthly performance since November 2023, climbing 6.2% as of May 2025 (source: @KobeissiLetter on Twitter, May 30, 2025). This significant rally in the stock market signals increased risk appetite among institutional investors, which historically correlates with higher inflows into cryptocurrencies like Bitcoin and Ethereum. Crypto traders should monitor this bullish equity momentum, as it often precedes increased volatility and potential upside in major digital assets due to improved overall market sentiment and liquidity.
