Stablecoins Hit $304 Billion the Same Week They Made Jackson Hole History

Two numbers landed in the same week and together they say something about how far stablecoins have moved from the margins of finance. The first is a market size figure. The second is a seating chart.

• $304+ billion: the total global stablecoin supply, according to DefiLlama data, after adding roughly $2 billion in a single week to reach a fresh all-time high.
• Tether’s share: USDT alone accounts for roughly $180 billion of that total, more than half the market, with USDC a distant second at around $75 billion.
• 49 editions: the number of prior Jackson Hole Economic Policy Symposiums held since the event began, none of which had ever put crypto or stablecoins on the official agenda.
• August 27-29: the dates of this year’s symposium, hosted by the Federal Reserve Bank of Kansas City under the theme “Financial Innovation: Implications for Payments and Policy.”
• Six papers, three panels: the portion of this year’s official program devoted to payments, tokenized finance, and banking, according to the published agenda.

Jackson Hole is not a crypto conference. It is the closest thing the world’s central bankers have to an annual retreat, a venue where policy ideas get floated a year or two before they show up in actual regulation. That the Kansas City Fed’s own brief named stablecoins alongside instant payments and digital payment systems this year, rather than treating them as a side conversation happening somewhere else at the same event, is what outlets covering the symposium have flagged as unprecedented in the event’s near half-century of history. One of the scheduled academic papers, from Stanford’s Darrell Duffie with European Central Bank board member Isabel Schnabel serving as discussant, focuses specifically on tokenized finance.

New Fed Chair Kevin Warsh delivered his first Jackson Hole keynote on Friday, August 28, his debut appearance in the role at the event. Crypto markets moved in response to the speech itself, with total market capitalization falling roughly 2.4% and Bitcoin dropping to around $77,700 as Warsh signaled that inflation remains too high for the Fed to offer near-term guidance on rate cuts. That reaction is a reminder that whatever role stablecoins now play on the Fed’s own agenda, monetary policy signals from the podium still move crypto prices more directly than a mention in a conference brief does.

The growth in stablecoin supply itself is not disconnected from federal policy. The GENIUS Act, signed by President Trump in July 2025, requires stablecoin issuers to back every token with dollars or short-term Treasuries and publish those reserve holdings monthly, a framework that has made the sector more attractive to institutional money rather than less. Analysts covering stablecoin supply as a market indicator have noted that a rising figure like this one tends to reflect capital sitting on the sidelines rather than capital actively deployed, meaning the current all-time high could be read either as dry powder waiting for the next entry point or simply as a larger pool of dollar-equivalent value moving through crypto rails than has ever existed before.
