Until recently, stablecoins were the plumbing of crypto markets—useful, technical, and largely invisible to most of the financial world. Now, in 2025, they are stepping onto the global stage, reshaping how money moves and who controls it. These digital assets, typically pegged 1:1 to the U.S. dollar, are processing more than $650 billion in transactions monthly and have grown to a circulating supply of over $240 billion. And with Wall Street heavyweights like Citigroup, Morgan Stanley, and Bank of America making direct moves into the space, the stablecoin boom has become impossible to ignore.
Last week, Citi's global head of Future of Finance, Ronit Ghose, described this moment as blockchain's "ChatGPT moment," a reference to the breakout year of generative AI. He wasn't exaggerating. A recent Citi report projected that stablecoin issuance could grow to $1.6 trillion by 2030 in a base case, and as much as $3.7 trillion under a bullish scenario, as reported by Reuters.
