While ISM data is only correlated with the crypto bull market, not causally related, it's still worth a look: First, let's understand what the ISM Index (Purchasing Managers' Index) is. It's a monthly report released by the Institute for Supply Management (ISM) to measure the health of the US manufacturing sector. Simply put, it's like a "barometer of factory owners' sentiment": an index above 50 indicates expansion and good business; below 50 indicates contraction and difficulties; and equal to 50 means flat. Past major cryptocurrency bull markets (such as those in 2013, 2017, and 2021, when prices skyrocketed) all occurred when the US ISM manufacturing index exceeded 50. Currently, this index has just jumped to 52.6, the largest increase since 2021. Previously, it mostly hovered below 50, only occasionally surfacing. Jesse believes this signals that cryptocurrencies are about to take off.
