US Treasury Bond-Buying Expansion Fuels 20% Ethereum (ETH) Rally

Ethereum (ETH), the largest altcoin by market capitalization, rallied roughly 20% in a single session, briefly trading as high as $2,311.8, after the U.S. Treasury announced it would double the size of its long-dated bond liquidity support operations. The trigger came from outside crypto markets. In an official statement on Aug. 19, the Treasury raised its per-operation purchase cap for the long-term securities facility from $2 billion to at least $4 billion, a step market participants quickly read as a “QE-lite” signal. The 30-year Treasury yield backed off its highest level since 2007, redirecting capital toward Ethereum and other risk assets. According to exchange order-book data, ETH crossed $2,000 during U.S. hours on Aug. 19 and printed its intraday peak of $2,311.8 shortly after 6:00 a.m. JST on Aug. 20, marking the first sustained break above $2,000 in about two months. The token had closed the prior session near $1,916.5; by 8:17 a.m. JST it was at $2,244, up 17.1%, while Bitcoin traded roughly 6% higher. Derivatives data underscored how violent the repricing was: $1.1085 billion in ETH positions were liquidated over 24 hours, with 91.77% of that total representing forced closures of short positions. The liquidation event affected 31,789 traders, with the single largest liquidation order worth $35.05 million. By venue, Binance accounted for $422.77 million, or 38.14%, of all ETH liquidation volume. ETF flow data aggregated from issuer disclosures showed an additional $102.3 million in net inflows into U.S. spot ETH funds on Aug. 17-18. On-chain analytics also points to an unusual market structure: ETH gained more than 20% between June 6 and Aug. 18 while futures volume fell roughly 70%, indicating that leveraged speculation has not been the primary engine. Whether this dynamic persists is likely to hinge on spot demand and continued institutional inflows over the coming sessions.

In South Korea, the same risk-on impulse showed up in retail order flow, though the won-denominated move lagged the dollar-based surge. Between 9:00 a.m. KST on Aug. 19 and 8:00 a.m. KST on Aug. 20, Ethereum rose 13.99% to 3,072,000 won on the Korbit exchange, with the 23-hour trading range spanning 19.18%. Turnover on that venue reached roughly 2.25 billion won, indicating active but not exceptional local participation. The Korbit print trailed the overseas high, a pattern consistent with Korean retail buyers chasing momentum after the offshore move had already started. The broader Korean session showed a broad risk-on tilt rather than an ETH-specific squeeze in the morning window: RE advanced 27.68%, TRUMP rose 19.17%, BTT jumped 33.33% and HYPE climbed 17.46%, while PRL fell 32.39% and CFG slipped 13.21%. BTT was the largest percentage mover, gaining 33.33% on Bithumb, although its total turnover was only about 13.8 million won. These double-digit swings imply that bear-market positioning built over the past two months was unwound quickly, echoing the short squeeze visible in global derivatives data. The won-denominated advance left ETH comfortably above the psychological 3 million won mark, a zone absent from local trading screens for about two months. In effect, Asia's morning session confirmed what Western hours had started: institutional and retail flows are now aligned behind the recovery. Even so, the most volatile Korean movers were smaller tokens, reminding traders that speculative heat in the region remains concentrated in low-liquidity names. Ethereum's gain on Korbit was substantial but orderly, and the lack of an outsized local premium suggests the rally is not yet showing the euphoric retail froth that often marks local tops.

COINOTAG's proprietary 42-indicator composite S/R scoring engine rates the $2,316.97 resistance at 68/100, driven by LVN, HVN, Fibo 0.000 and Donchian Upper; the closest support at $2,236.49 also scores 68/100 on Fibo 0.114 and HVN. RSI at 82.70 leaves ETH overbought in the short run, although the price remains far from its all-time high — a condition that systematic and AI trading bot frameworks often use to trim risk. Derivatives data shows funding at 0.0013%, open interest at $8.98 billion and a 1.29 long/short account ratio, suggesting leverage is not yet stretched. With the Fear & Greed Index at 62/100, the bias is constructive. A sustained close above $2,316.97 targets $2,558.86; losing $2,236.49 would invalidate the breakout and expose $2,038.15.
