Why Treasury Buybacks Sent Bitcoin and Ethereum Into a Short-Squeeze Rally

The crypto rally that began on August 19 had a clear macro spark but a more mechanical engine. The U.S. Treasury said it would at least double the maximum size of liquidity-support buybacks for longer-dated nominal coupon securities—from $2 billion to at least $4 billion per operation—starting September 9 and covering the 10-to-20-year and 20-to-30-year sectors.

Markets interpreted the announcement as supportive of Treasury-market liquidity and broader financial conditions. That encouraged buying across risk assets, including crypto. But the speed and scale of the move were more consistent with a derivatives-driven short squeeze than with a purely spot-led change in long-term demand.

The Treasury announcement was the initial risk-on catalyst

Treasury buybacks are purchases of outstanding Treasury securities before maturity. Treasury describes liquidity-support buybacks as a way to bolster market functioning, rather than as a conventional monetary stimulus program.

The immediate market interpretation was nevertheless constructive: larger purchases in the long end could improve liquidity and ease pressure from elevated long-term yields. Reporting on the move said the 30-year Treasury yield fell from 5.31% to 5.21% as Bitcoin broke above $68,000.

That does not mean Treasury directly purchased crypto or injected an equivalent amount of cash into digital assets. The transmission mechanism was investor expectations: if bond-market liquidity improves and long-term yields become less restrictive, traders may be more willing to hold higher-risk assets.

Bitcoin and Ether moved sharply higher

Bitcoin initially gained about 7%, broke above $68,000 and later traded through $69,000. Ether outperformed, rising roughly 17–18%, reclaiming $2,000, moving near $2,100 and later approaching $2,300.

The difference in performance mattered. Bitcoin’s move helped establish a broader risk-on tone, while Ether’s break through a heavily watched psychological and technical level forced additional buying from traders positioned for a decline.

Short liquidations turned a rally into a cascade

The strongest evidence that leverage amplified the move came from liquidation data. Early reports put 24-hour crypto short liquidations at approximately $1.4 billion, while later estimates approached $3 billion as the rally extended.

One report counted about $1.74 billion in short liquidations against $173 million in long liquidations during the initial Bitcoin breakout. Another estimate put Ethereum futures liquidations near $382 million over a 24-hour period, with roughly $360 million coming from shorts.

The figures are not identical because they cover different time windows, venues and types of contracts. The consistent conclusion is that bearish leveraged positioning was unusually concentrated. As prices moved through resistance, exchanges liquidated short positions. Those liquidations required positions to be closed, creating forced buying that pushed prices higher and triggered more liquidations.

That feedback loop explains why the rally became nearly vertical. It also creates the central risk: forced demand disappears once the most vulnerable short positions have been closed.

Ether’s $2,000 breakout was technically important—but not conclusive

Ether’s move above $2,000 was more than a round-number breakout. Reports identified the area as a major psychological and technical barrier, and the move placed ETH above its 200-day moving average, a widely followed long-term trend measure.

If ETH can hold $2,000 on closing bases, the former resistance zone could become support. If it loses that level, the bullish interpretation would weaken and a retreat toward earlier liquidity areas near $1,925 or $1,940–$1,950 becomes more plausible.

Technical indicators alone cannot establish a durable trend reversal. The more useful test is whether Ether can remain above the 200-day average and $2,000 after liquidation activity, funding rates and open interest return to more normal conditions.

ETF inflows supplied genuine spot support

The rally was not only a futures-market event. U.S. spot Ether ETFs reportedly attracted about $71.4 million in net inflows on August 18, with BlackRock’s ETHA contributing approximately $64.7 million in one dataset.

Later reporting cited roughly $189 million in daily Ether ETF inflows as the rally broadened. These flows provide evidence of direct spot demand alongside the derivatives squeeze, although they do not prove that institutional buying—not forced short covering—was the primary driver of the fastest part of the move.

The distinction matters. ETF inflows can help support prices after a breakout, but a short squeeze can produce outsized gains even when underlying demand is not yet strong enough to sustain them.

Regulatory news added a second layer of optimism

The Treasury announcement arrived alongside a more favorable regulatory narrative for crypto. The SEC proposed “Regulation Crypto Assets,” a tailored securities-offering regime for certain investment contracts involving crypto assets. The agency described the proposal as a framework for clearer capital-raising pathways; it was not an enacted rule.

At the same time, broader market-structure legislation remained uncertain. Reporting said the proposed CLARITY Act was stalled in Congress while the SEC pursued its own framework.

Together, those developments improved sentiment by suggesting that crypto businesses could eventually face clearer rules for issuing assets and raising capital. They were supportive context, not a direct explanation for the scale of the intraday liquidations.

What would confirm a lasting trend reversal?

The evidence points to a layered rally:

1. Macro repricing: Treasury’s larger long-end buyback cap was read as supportive of liquidity and risk appetite.
2. Regulatory optimism: The SEC’s proposal offered a potential capital-raising pathway, while the CLARITY Act remained unresolved.
3. Spot demand: Ether ETFs recorded reported inflows, led in one dataset by BlackRock’s ETHA.
4. Forced buying: Short liquidations, especially in Bitcoin and Ether derivatives, accelerated the move.

The final factor appears to have been decisive for the rally’s speed. A lasting recovery would require more than a single liquidation event: sustained closes above Ether’s 200-day moving average and $2,000, continued ETF inflows, and renewed spot demand after derivatives positioning normalizes.

Until those conditions appear, the most defensible reading is that Treasury’s announcement opened the door to a broad risk rally, while crowded short positioning supplied the fuel. The price move was real, but its durability remained a question rather than an established fact.
