Ethereum experienced significant volatility in May 2025, triggered by geopolitical events impacting market flows and institutional investment activity. News of US tariffs resulted in sell-off pressure, followed by an influx of institutional investors seeking opportunity amidst the volatility. The price dropped on May 31st, but overall value increased significantly during the month thanks to whale accumulation and increased ETF inflows. 385,000 ETH was transferred from large accounts to Binance which suggests potential for future market fluctuations. These developments highlight the continuing influence of institutional participation in Ethereum’s trading dynamics.
