$ETHBTC

Observing the ETHBTC pair's recent movements, it appears less susceptible to direct macro economic data releases compared to $BTC's reaction. While $BTC often shows immediate volatility around CPI or FOMC announcements, $ETHBTC seems to be carving its own path, possibly influenced more by network developments or specific $ETH demand. Has anyone done a deeper dive into the divergence in correlation coefficients between $BTC/USD and $ETHBTC during key macro events over the past year? I'm curious if this decoupling is a sustained trend or just recent noise. Specifically, I'm looking at the periods around the last three major central bank rate decisions. Any data or analysis would be appreciated.
