COIN Stock Surges 9.55% to $160 as OCC Targets November for Stablecoin Rules

Coinbase (NASDAQ: COIN) stock closed up 9.55% at $160 on August 19, its strongest single-day performance in months. The move tracked a broader crypto market rally after the U.S. Treasury announced plans to expand bond buybacks and the Office of the Comptroller of the Currency signaled it is nearing completion of stablecoin rules under the GENIUS Act. Bitcoin (BTC) climbed toward $69,700 the same day, its highest level since early June.

OCC Targets November for GENIUS Rules

Comptroller of the Currency Jonathan Gould told the Wyoming Blockchain Symposium in Jackson Hole on August 19 that the OCC intends to publish final payment-stablecoin rules by November. The statutory deadline for federal regulators to complete GENIUS Act rulemaking passed on July 18, 2026, one year after President Trump signed the law, but the OCC, Federal Reserve, FDIC and National Credit Union Administration still had ten rulemakings pending. Gould said the office is weighing industry feedback on its 376-page proposal, which covers reserves, redemptions, custody and issuer applications, before issuing a final version. A November rule would let the OCC begin processing stablecoin issuer applications in early 2027.

COIN Tests Key Resistance After Rally

Coinbase shares opened at $148 on August 20 after pre-market trading pushed the price near $171, extending Wednesday’s gains. The stock is now testing resistance at its 50-day EMA near $160; a close above that level opens a path toward the 150-day EMA near $172, with $190 in range if buying pressure holds. An RSI reading between 53 and 60 points to strengthening bullish momentum. A pullback could send shares back toward support at the 20-day EMA near $153.

The rally followed Treasury Secretary Scott Bessent’s announcement that the department will at least double its long-term bond buyback operations, raising the cap from $2 billion to $4 billion per operation starting September 9. The 30-year Treasury yield, which had touched 5.34% earlier in the week, fell to about 5.19% after the announcement.

• Bitcoin rose roughly 6% to 8% intraday, touching $69,700
• Ether (ETH) jumped close to 9%, its largest single-day move since March
• More than $1 billion in short positions were liquidated within hours, per CoinGlass data

CLARITY Act Vote Looms September 15

Coinbase CEO Brian Armstrong met President Trump and other crypto executives at the White House on August 19 to discuss the pending CLARITY Act market-structure bill. Senate Banking Committee Chairman Tim Scott said the bill has a realistic chance of advancing when the chamber holds a procedural vote on September 15. Prediction markets still price the odds of passage in 2026 below 30%, reflecting unresolved disputes over crypto ethics provisions and staking-reward treatment.

Conclusion

Coinbase’s August 19 rally rests on three converging catalysts: Treasury liquidity support for long-term bonds, Bitcoin’s technical breakout above key moving averages, and concrete progress on stablecoin regulation. None of these guarantees COIN holds above $160. The stock’s next move depends on whether the Senate advances the CLARITY Act on September 15 and whether the OCC delivers final GENIUS Act rules on schedule in November. Traders watching COIN should treat both dates as the next real tests of this rally, not just headlines.
