The cryptocurrency sector experienced a significant rally on Monday, with Circle and Coinbase at the forefront, driven by advancements in U.S. digital asset regulation and bitcoin's break above the $80,000 threshold.

Circle, the issuer of the USDC stablecoin, saw its stock rise by 18%, while Coinbase, a U.S.-focused crypto exchange, increased by approximately 7%. Other notable gainers included BitGo, a digital asset infrastructure firm, which climbed around 10%, and companies like Strategy, Robinhood, and Bitmine, which saw increases of 3%-4%, reflecting a broad-based market upswing. The rally was fueled by bitcoin's push past $80,000, reaching its highest level since late January, and providing a boost to the entire crypto sector.

The CoinDesk 20 Index, a benchmark for the broader crypto market, rose by 1.2% as bitcoin advanced nearly 2% over the past 24 hours. The recent progress on the Digital Asset Market Clarity Act, a crucial piece of U.S. legislation aimed at regulating crypto markets, has further enhanced investor sentiment. A newly proposed compromise would restrict stablecoin issuers from offering yield on idle balances while permitting rewards tied to usage and transaction activity.

This development addresses a key point of contention in the bill and aligns with previous discussions in Washington. According to Markus Thielen, founder of 10x Research, this clarification brings the bill closer to passage. The stablecoin yield issue has been resolved, and lawmakers are expected to proceed with a formal markup, potentially as early as this week.

The odds of the bill's passage have increased to 64% on the prediction platform Polymarket, reflecting growing confidence in its advancement. As a result, equity markets are starting to price in potential winners, with Circle, a regulated stablecoin issuer, widely seen as a likely beneficiary of clearer regulations, particularly if stablecoins are formally recognized as payment tools rather than yield-bearing assets. The firm's upcoming earnings report, scheduled for release next week, adds another layer of momentum for the stock.
