Bitcoin closed Friday at $76,943.90, up 22 percent for the week, its best five-day run since March 2024. Strategy gained 29 percent. Coinbase gained 25 percent. Circle gained 22 percent. None of that came from a single piece of crypto-specific news. It came from a bond market announcement and a legislative push landing in the same 72 hours.
A Treasury Buyback Announcement Knocked Yields Down and Lifted Everything Risky
The U.S. Treasury Department announced Wednesday, August 19 that it will at least double the size of its liquidity-support buyback operations for longer-dated nominal coupon securities, the 10-to-20-year and 20-to-30-year sectors, from a $2 billion per-operation cap to at least $4 billion. The change takes effect September 9 and runs through November 4, 2026, when Treasury’s next quarterly refunding review is scheduled. These are liquidity-support purchases of older, less-traded securities, not new debt issuance or a form of quantitative easing, and Treasury framed the move as a response to persistently strong investor demand to sell into its existing buyback operations.
The announcement came a day after the 30-year Treasury yield hit its highest level since 2007 and the 10-year hit a 19-year high, following an August 30-year bond auction that cleared at 5.216 percent. Yields dropped immediately: the 30-year fell about 9 basis points to 5.196% and the 10-year fell roughly 5 basis points to 4.647%. Lower long-term yields reduce the discount rate applied to future cash flows and speculative assets generally, which is the standard mechanical reason a Treasury market announcement with no direct crypto connection can still move bitcoin. Stock futures rose sharply the same morning.
Trump and Crypto Executives Made a Last-Ditch Push Ahead of the September 15 Vote
Sentiment accelerated further on Thursday, August 20, when President Trump publicly called on senators to pass the Digital Asset Market Clarity Act, the market structure bill whose cloture vote we covered two weeks ago after Senate Majority Leader Thune locked in a September 15 floor date. The White House hosted CEOs from Coinbase, Kraken, Robinhood, Ripple, and Chainlink at a last-minute event the same week. Coinbase CEO Brian Armstrong told CNBC he was “pretty optimistic it’ll get over 60 votes,” while acknowledging the ethics provision tied to Trump’s own crypto holdings remains one of the more contentious unresolved issues, the same dispute flagged in our prior coverage.
Strategy rose 29 percent for the week, its best since April 17. Coinbase rose 25 percent, its best week since May 2025. Circle gained 22 percent and Robinhood gained 13 percent. Bitcoin’s two-day gain into Thursday alone ran to 12 percent, moving from roughly $63,000 early in the week to above $77,000 by Friday’s close. Reporting via CNBC.
The Rally’s First Test: Bitcoin Slips Back and the Bill’s Odds Still Look Slim
Bitcoin gave back some ground over the weekend, trading at $76,536 on Sunday, down 0.8 percent over 24 hours after surrendering earlier gains that had carried it briefly above $77,300. Even after the week’s surge, bitcoin remains well below its 2026 high of $94,820 set in mid-January and its all-time high of $126,198 from October 6, 2025.
CNBC’s own reporting on the rally noted directly that the Clarity Act is “widely viewed as a key catalyst that could push the market out of the crypto winter that began last fall, but the chances of it passing appear relatively slim,” a caveat that sits uneasily next to a week of double-digit percentage gains built partly on that same bill’s momentum. The bond buyback program does not begin until September 9, six days before the Senate’s scheduled cloture vote, meaning both catalysts behind this week’s move remain unrealized until deep into next month.
September 9 Buyback Start and September 15 Cloture Vote Are the Two Dates That Test This Rally
September 9: Treasury’s expanded buyback operations actually begin. Whether the yield relief that triggered this week’s rally proves durable once the program is live, rather than just announced, is the first test.
September 15: the Senate’s cloture vote on the Clarity Act, covered in our August 10-17 report. Armstrong’s public 60-vote optimism will either be validated or exposed as sentiment that ran ahead of the actual math.
