U.S. Treasury Supercharges Bond Buybacks, Sparks Crypto Short Squeeze as Bitcoin Jumps Toward $77,000

Crypto markets got the macro catalyst they'd been missing. The U.S. Treasury doubled its long-duration bond buyback program, a move traders read as a meaningful liquidity boost that helped pressure the dollar and reset risk appetite across markets. Bitcoin broke out of months-long tight ranges as leveraged shorts were forced to cover, propelling BTC to near $77,000. Sentiment flipped rapidly. The Fear & Greed Index surged from 29 (Fear) last week to 72 (Greed) within days, reflecting a dramatic shift in positioning and momentum. Why the buybacks mattered Treasury buybacks of longer-dated bonds support bond prices and push yields lower. Falling long-term yields typically improve the relative appeal of risk assets, including crypto. The process also puts cash back in the hands of bondholders who sell into the buybacks, cash that often seeks new opportunities. The dollar's decline added a second tailwind. A softer greenback tends to support Bitcoin and other digital assets by easing financial conditions and making dollar-denominated assets more attractive to non-U.S. buyers. With crypto stuck in narrow bands for months, short sellers had built crowded positions. Once the macro backdrop shifted, those shorts were caught offside. As prices climbed, forced covering accelerated the move in a self-reinforcing squeeze. ETF inflows confirm institutional demand Spot Bitcoin ETFs recorded about $1.6 billion of net inflows from Monday through Thursday, the strongest weekly pace of 2026 so far. The flow strength suggests traditional allocators responded quickly to the liquidity signal. The ETF data matters because it reflects institutional allocations rather than leveraged futures activity. Heavy absorption by products from BlackRock and Fidelity points to deliberate portfolio positioning by advisors and asset managers. Bitcoin posted a 7-day gain of 23.6%, including a 24-hour jump of 7.8%. Trading near $77,000 places BTC close to levels that looked out of reach just two weeks ago. Altcoins follow through The squeeze broadened beyond Bitcoin. Ethereum rose to around $2,400, up 5.0% over 24 hours. Solana held above $91 with a 6.2% daily gain. XRP climbed past $1.40. Over seven days, Bitcoin forks led all categories with a 39.5% surge, a classic risk-on signal. When capital rotates into more speculative segments, it often indicates traders expect the rally to extend rather than fade as a brief rebound. Market breadth also stood out. In weaker rallies, Bitcoin often pulls liquidity away from altcoins. This time, the advance was broad-based, consistent with an overall liquidity expansion tied to a macro driver rather than a simple rotation. What matters next The key question is whether the liquidity impulse from Treasury buybacks persists. Buybacks are not a one-off event. If the Treasury maintains or expands the program, the supportive backdrop for risk assets could last beyond the initial squeeze. Dollar direction remains critical. Continued weakness would reinforce the bullish setup. Stabilization or a rebound could pressure recent gains, particularly in thinner altcoin markets. The speed of the sentiment swing also warrants caution. Rapid flips from fear to greed can overshoot, and positioning can become crowded quickly on the long side. In the near term, ETF flows over the next two weeks will be the clearest read on whether institutional demand is becoming structural. If weekly inflows remain above $1 billion, the rally has stronger footing. If flows fade sharply, markets may have already priced in much of the good news. For now, conditions have shifted in crypto's favor. Treasury buybacks loosened financial conditions without a formal policy pivot, giving digital assets a real macro signal to trade for the first time in months.
