Bitcoin Cycles and the ISM PMI: A Curious Correlation
- 

A growing number of analysts are eyeing the ISM Manufacturing PMI as a key macro signal for Bitcoin’s market cycles.
The index, which tracks U.S. industrial activity, has historically aligned with major Bitcoin peaks, a trend first popularized by Raoul Pal and later expanded by Colin Talks Crypto.
Colin notes that “all three past Bitcoin cycle tops have broadly aligned with this monthly, oscillating index.” If that rhythm holds, the data suggests the current Bitcoin cycle could last longer than usual — potentially signaling a slower but more extended bull run.
