XRP Leads a Broad Crypto Bid on the Eve of a Senate Vote and a Fed Decision

Cryptocurrencies extended gains through Monday’s U.S. session as bitcoin rose to roughly $79,164, recording a 2.3% increase over 24 hours and setting its session peak after the New York open. Total crypto market capitalization reached about $2.773 trillion on $77.6 billion of reported volume, with bitcoin accounting for roughly 57.2% dominance. Among major tokens, XRP outperformed with a 7.7% jump to $1.46, while ether traded near $2,541.82 and Solana and BNB were modestly higher. Market participants pointed to two imminent, time‑specific events as the main catalysts: a Senate cloture vote on the CLARITY Act and the Federal Reserve’s policy meeting. The cloture motion for H.R. 3633 is scheduled to ripen at 2:15 p.m. ET on Tuesday, Sept. 15, 2026; Majority Leader John Thune filed the motion with 16 Republican co‑signers, and Republicans’ 53 seats mean seven Democrats would be needed for the 60‑vote threshold. Senators Cynthia Lummis, John Boozman and Tim Scott released what they described as the final draft of the bill on Monday morning. The bill’s release states it incorporates 126 substantive changes sought by Democrats, adds ethics provisions mirroring much of the Tillis‑Gallego package including a role for state attorneys general, gives the Treasury Secretary authority aimed at preventing deposit runs tied to payment stablecoins, and modifies the Blockchain Regulatory Certainty Act to more clearly shield developers from money‑transmission registration. Polymarket traders priced the probability that the CLARITY Act would be signed into law in 2026 at about 29.5% on Monday afternoon, on roughly $16.6 million of cumulative volume. Monetary policy bets also tightened ahead of the Federal Open Market Committee meeting Sept. 15–16. Polymarket put the likelihood of a quarter‑point rate increase at about 85.5% on $156.9 million of volume, up from earlier in the day, with no‑change odds near 14.5%. Treasury yields have moved higher in recent sessions, and traders are watching the FOMC’s decision and the accompanying Summary of Economic Projections for guidance. Outside crypto, equities and commodities diverged: the S&P 500 traded down around 0.3% in the afternoon, gold fell roughly 1.3%, and crude oil pared an overnight spike, trading near $101–$106 a barrel depending on the contract. Market participants noted that the pairing of a major legislative vote and a Fed decision within 48 hours is concentrating volatility and positioning into a narrow time window.
