JPMorgan sees $500B market, Standard Chartered $2T; GENIUS Act and MiCA rules reshape issuance, while Amazon's AI agent payments use USDC via Coinbase and Stripe.
The stablecoin market is facing a regulatory overhaul that will determine which digital dollars survive and which get sidelined. The US GENIUS Act, passed by the Senate, and the EU’s MiCA framework are converging to create a licensing regime that favors banks and regulated institutions. At the same time, Amazon Web Services has launched a stablecoin payment system for AI agents using USDC, and BlackRock is planning money-market funds tailored for stablecoin users. JPMorgan projects the market could reach $500 billion by 2028, while Standard Chartered sees $2 trillion. The simple read is that stablecoins are going mainstream. The better read is that the structure of issuance is shifting from crypto-native firms to banks, and that shift will change liquidity, counterparty risk, and the very definition of a stablecoin for traders.
The GENIUS Act, which passed the Senate, determines how stablecoins are issued, used, and reported. While the full text of the act’s provisions is still being digested, the World Economic Forum has flagged three key areas that will shape the market. Separately, the EU’s MiCA framework is already explicit: e-money tokens (EMTs), which are backed by fiat currency, can only be issued by e-money institutions or credit institutions. Asset-referenced tokens (ARTs), backed by a basket of assets, can only be issued by EU-based entities and must be authorized by regulators. This dual regulatory push creates a moat around bank-issued stablecoins and raises immediate questions about the future of existing non-bank stablecoins like Tether’s USDT.
The risk is not just compliance paperwork. If exchanges and platforms are forced to delist stablecoins that do not meet these new standards, a rapid rotation into compliant coins could disrupt liquidity. A trader holding USDT as collateral on a derivatives exchange might suddenly face a conversion event or a freeze, triggering forced selling. The mechanism is straightforward: regulatory clarity is a catalyst, but regulatory fragmentation is a liquidity risk. The better market read is that the GENIUS Act and MiCA are not just about consumer protection; they are about who gets to issue the digital dollars that underpin crypto trading, and that battle will determine the cost and availability of stablecoin liquidity for years.
Tether’s USDT is the largest stablecoin by market cap and the dominant quote asset on centralized exchanges. Its reserve composition and regulatory status have been a persistent source of debate. If the GENIUS Act imposes strict reserve and reporting requirements, USDT could face a structural disadvantage. The market has so far priced in a low probability of a sudden disruption, but the risk is asymmetric: a forced restructuring or loss of market access would not only hit USDT holders but could trigger a broader deleveraging as collateral is repriced.
Circle’s USDC is the obvious beneficiary. Already positioned as a regulated stablecoin, USDC is the settlement rail for Amazon’s new AI agent payment system, built in partnership with Coinbase and Stripe. That integration gives USDC a real-world demand driver that extends beyond crypto trading. Meanwhile, large US lenders including Bank of America and Citibank are working on launching their own stablecoins. JPMorgan Chase CEO Jamie Dimon, a long-time bitcoin sceptic, recently revealed the bank might consider involvement in stablecoins. BlackRock’s planned money-market funds for stablecoin users add another layer: they offer yield, which could pull capital away from non-yielding stablecoins and concentrate it in instruments that sit inside traditional financial plumbing.
The exposure is not just about market share. If banks issue stablecoins that are perceived as safer because of their regulatory status and institutional backing, the collateral base for DeFi could shift. Lending protocols that rely on USDT or USDC as collateral might see liquidity migrate to bank-issued coins that are not as freely usable in permissionless smart contracts. That fragmentation would increase the cost of leverage and complicate cross-margin positions.
JPMorgan’s $500 billion and Standard Chartered’s $2 trillion projections for 2028 imply a compound growth rate that far exceeds the current stablecoin market cap. The wide gap is not just a difference in optimism; it reflects fundamentally different assumptions about who will issue stablecoins and how they will be used. The lower end assumes that existing stablecoins continue to grow but face regulatory headwinds that cap their expansion. The upper end assumes that banks capture a significant share of payments, remittances, and institutional settlement, and that stablecoins become the default layer for machine-to-machine transactions.
What is priced into crypto markets today is a muddle. The dominance of USDT suggests that traders are not yet discounting a regulatory shock. If the market believed the $2 trillion scenario was imminent, we would see a rotation into infrastructure plays like Coinbase and a compression of yields in DeFi as stablecoin supply explodes. Instead, the mixed signals–banks exploring issuance while existing stablecoins continue to grow–suggest that the market is waiting for a concrete catalyst. That catalyst could be the final implementation rules of the GENIUS Act or the first major bank-issued stablecoin launch.
Amazon Bedrock AgentCore Payments, which lets AI agents make instant payments for digital services using USDC, is a concrete use case that could drive transaction volume independent of speculative trading. The system was developed with Coinbase and Stripe, making USDC the settlement rail. This validates stablecoins for machine-to-machine payments, a niche that could scale rapidly if other cloud providers follow. For Coinbase, the partnership could increase transaction revenue and cement its role as infrastructure provider, but the scale is still nascent. The real test is whether developers adopt the system and whether the payment volume becomes material enough to move Coinbase’s revenue needle.
The risk for traders is that this use case gets overhyped before it generates meaningful flow. If Amazon’s system remains a pilot, the demand boost for USDC will be limited. If it scales, it could create a structural bid for USDC that reduces its volatility and increases its utility as collateral. That would further entrench USDC as the compliant stablecoin of choice, potentially at the expense of USDT.
The risk of a disorderly stablecoin transition can be reduced by clear, interoperable standards that allow multiple stablecoins to coexist. If the GENIUS Act provides a path for existing stablecoins to become regulated without a forced redenomination or freeze, the market can absorb the shift gradually. Transparent reserve audits and a clear timeline for compliance would let traders adjust positions without panic.
The risk worsens if regulators take sudden enforcement action against a major stablecoin issuer. A freeze or depegging of USDT would trigger cascading liquidations across centralized and decentralized exchanges, given its role as collateral. A fragmented market where bank-issued stablecoins are not interoperable with DeFi protocols would reduce the efficiency of crypto trading and increase basis risk. If banks issue stablecoins but restrict their use to closed-loop systems, the open, permissionless nature of crypto would be undermined, and the total addressable market might fall short of even the $500 billion projection.
JPMorgan (JPM) carries an Alpha Score of 50, reflecting mixed sentiment, but its exploration of stablecoins could be a catalyst if it moves from consideration to launch. Coinbase (COIN) has an Alpha Score of 36, suggesting the market has not fully priced in the potential of its Amazon partnership and stablecoin infrastructure. Traders can track these scores on the JPM stock page and COIN stock page. The lobbying push around the CLARITY Act, as covered in Banking Lobby Seeks Yield Amendment Ahead of CLARITY Act Markup, shows that the fight over stablecoin yield and bank involvement is far from settled.
