According to Evan (@StockMKTNewz), the monthly US Consumer Price Index (CPI) year-over-year inflation data since 2015 highlights significant periods of rising and falling inflation, especially during 2021-2023. For crypto traders, these CPI trends are critical as higher inflation often triggers volatility in Bitcoin and Ethereum prices, with digital assets being used as hedges against traditional fiat devaluation (source: @StockMKTNewz, Twitter, May 25, 2025). Persistent inflation above the Federal Reserve's 2% target has historically led to increased market uncertainty and price swings in major cryptocurrencies.
