Why does rising ETH open interest matter for price?
Rising ETH open interest often signals increased leverage and conviction among traders. When open interest climbs alongside inflows, it can magnify moves: liquidations can accelerate rallies or corrections. In this instance, the OI spike coincided with renewed buying that pushed ETH back above $4,300.
When did the price reaction occur and what were the numbers?
Following the CME milestone, Ethereum registered a 4.09% gain in the last 24 hours, trading near $4,326 based on CoinMarketCap data. The recorded CME OI figure—about 14.25M ETH—translates to roughly $8.3 billion notional exposure at prevailing prices.
