ETH rises moderately by 0.95% in 15 minutes: exchange reserves decline and ETF inflows converge to drive a short-term rebound

From 05:00 to 05:15 (UTC) on June 20, 2026, ETH/USDT returned +0.95% within 15 minutes. The price rose from 1,712.21 USDT to 1,733.26 USDT, with a 1.23% range. This period coincided with the Asian trading session about to begin; liquidity was thinner than in European and US sessions, and price action showed a mild upward trend.

The main driver behind this unusual move was that exchange ETH reserves continued to decline to 14.5M ETH. Temporary sell pressure was released, providing bottom support for the price. CryptoNews data shows that declining exchange reserves usually means less ETH available for immediate selling, shifting the supply-demand balance in favor of sellers.

Second, US spot Ethereum ETFs saw net inflows of $22.5M on June 15, ending the prior streak of four straight trading days of net outflows. The cumulative outflow trend of about $85M was reversed. Market expectations for institutional demand improved at the margin, boosting sentiment. In addition, 05:00 UTC corresponds to 13:00–14:00 Eastern Asia time; the start of the Asian trading session brought incremental buy orders. Meanwhile, ETH open interest is at a historical high and traders remain bearish, so the risk of a potential short squeeze could amplify volatility when the price rebounds.

For risk warnings, the user-specified 15-minute window is extremely short, making random effects more significant and limiting the statistical significance of attribution analysis. OKLink large-transaction data covers only transfers exceeding 10,000 ETH; smaller-scale accumulated buying may not have been captured. Going forward, key focus should be on the $1,700 support level and the persistence of ETF fund flows; short-term volatility risk remains.
