Stablecoin Market Cap Surpasses $300 Billion — "Dry Powder for Crypto Assets" Indicates a Quiet Tectonic Shift

Why is it important?The market capitalization of stablecoins surpassing $300 billion signifies that "dry powder" within the crypto asset ecosystem has reached an all-time high. However, its composition is fundamentally different from the DeFi bubble of 2021. Real-world demand, such as international remittances, B2B payments, and dollarization in emerging economies, is driving growth, rather than trading speculation, and the passage of the GENIUS Act in the United States has made this trend irreversible. For banks, an existential crisis in the form of deposit outflows is quietly unfolding.

Summary:While the stablecoin market capitalization has exceeded $300 billion, this is not a repeat of the speculative money seen in 2021, but rather a sign of the simultaneous progression of the digital expansion of dollar hegemony and a structural outflow from bank deposits.

What happened?

• Market capitalization— The total market capitalization of stablecoins has reached $312 billion, a sixfold increase from approximately $50 billion in early 2020.
• Market structure— USDT holds $184 billion (60.7% share), and USDC holds $75.7 billion (24% share), with the top two brands accounting for 93% of the total, creating an oligopolistic structure.
• Trading volume— Stablecoin transaction volume will reach $33 trillion in 2025, exceeding the combined volume of Visa and Mastercard. This represents a 72% increase year-over-year.
• GENIUS Method— The first comprehensive stablecoin regulatory law in the United States, signed on July 18, 2025. Mandates 1:1 reserves, backing by short-term Treasury securities, and monthly disclosures.
• Bank Actions/Movements— JPMorgan Chase, Bank of America, Citigroup, and Wells Fargo are reportedly considering jointly issuing a stablecoin.

Overall picture; big picture; holistic view

Historical context

The history of stablecoins is the history of "trust" itself in the cryptocurrency market. When Tether appeared in 2014, it was merely a "convenient tool" for streamlining fund transfers between exchanges. After the DeFi Summer of 2020, stablecoins experienced explosive growth as the base currency for liquidity provision, leveraged trading, and yield farming, reaching $150 billion in December 2021.

However, in May 2022, the collapse of the algorithmic stablecoin UST/Luna changed everything. $45 billion evaporated in a week, proving that "stability without reserves" was an illusion. In March 2023, the SVB collapse caused USDC to temporarily depeg to $0.86, leaving the lesson that "reserves deposited in banks are not safe either."

These two crises defined the current structure of the stablecoin market. Algorithmic stablecoins have virtually disappeared, and fiat-backed stablecoins have become dominant. The GENIUS Act of 2025 legally mandated 1:1 reserve backing and investment in short-term Treasury securities with maturities of 93 days or less, formally positioning stablecoins as "regulated digital dollars." What was once a gray area has become part of the U.S. financial infrastructure.

It is noteworthy that this institutionalization is not accidental but a strategic choice. The Trump administration explicitly positioned stablecoins as a "mechanism for maintaining dollar hegemony" in an executive order. The European Central Bank's concern about the spread of dollar-denominated stablecoins in the Eurozone as "digital dollarization" is evidence that this strategy is beginning to take effect.

Stakeholder Map

Structural Insights from Data

• $312 billion— Total market capitalization of stablecoins. Has grown approximately 6x since the beginning of 2020.
• 33 trillion dollars— 2025 annual stablecoin transaction volume. Exceeds the combined total of Visa + Mastercard.
• 93%— Total market share of USDT and USDC. A de facto duopoly.
• $141 billion— Tether's US Treasury holdings. One of the world's largest holders of US Treasuries.
• Over $10 billion USD— Tether's net profit in 2025. The yield on government bonds in its reserves is the primary source of revenue.
• $6.6 trillion— U.S. Treasury Department Estimate of Potential Bank Deposit Outflows to Stablecoins
• $226 billion— Stablecoin usage in B2B payments. Approximately 60% of the total.
• 0.39%— The average U.S. deposit interest rate, a significant difference from the 3.5% or more offered by stablecoin operations.

Reading Between the Lines — What the Reporting Isn't Saying

The most important thing behind this "surpassing $300 billion" milestone is that the phase where stablecoins exist solely for crypto assets is coming to an end. 60% of transaction volume is B2B payments, remittance costs have decreased from the traditional 6.5% to less than 2%, and Visa and PayPal are deploying their own stablecoins. In other words, stablecoins are no longer just "waiting funds for crypto assets," but are becoming competitors to existing international remittance and payment infrastructure. Furthermore, with the GENIUS Act limiting reserves to short-term Treasury bonds, the more the stablecoin market expands, the more structural buyers of U.S. Treasury bonds will increase. The real reason the U.S. government welcomes stablecoins is not consumer protection or innovation promotion, but the alignment of geopolitical interests in the global expansion of the dollar-denominated payment network and the stabilization of Treasury bond demand. The ECB's warning about this structure as "digital dollarization" is simply because they accurately understand the essence of this game.

NOW PATTERN

Path dependence × Chain of contagion

The institutionalization of stablecoins via the GENIUS method is creating an irreversible path, with its effects cascading into bank deposits, the government bond market, and emerging market currencies.

Path Dependence: The Road the "Digital Dollar" Has Taken May Be Irreversible

The establishment of the GENIUS method has solidified an irreversible path toward the "institutionalization" of stablecoins. The question is, where does this path lead?

Path dependency is the dynamic in which initial choices constrain subsequent options, making a change of course structurally impossible beyond a certain point. In the case of stablecoins, that turning point was the signing of the GENIUS Act in July 2025.

The significance of this law lies in its definition of stablecoins not as a "threat to be regulated," but as an "infrastructure to be leveraged."A 1:1 reserve backing requirement, restrictions on investing in short-term government bonds with maturities of 93 days or less, and monthly disclosure obligations — these may appear to be "regulatory tightening" at first glance. However, the essence is the opposite. By complying with these rules, it grants "permission" for anyone to legally issue a digital dollar.

There are three reasons why this route is irreversible. First,Tether has become one of the world's largest bond investors, holding $141 billion in U.S. Treasury bills.- The U.S. government no longer has an incentive to stop Tether's purchase of U.S. Treasury bonds. - Circle has turned the cost of regulatory compliance into a competitive advantage as the only major issuer compliant with both the GENIUS Act and EU MiCA. Latecomers cannot withdraw until they recoup this investment. - Four major U.S. banks, including JPMorgan Chase, are considering jointly issuing a stablecoin.Once banks transition from being "competitors" to "participants" in the stablecoin space, the survival of this market will be guaranteed by the vested interests of the financial system.

More importantly, the GENIUS Act stipulates that only authorized entities can issue stablecoins after January 18, 2027. In other words, the system is designed to close the regulatory door after it has been opened. If you don't get on this path now, you may never be able to. Circle's successful IPO (up 675% after listing) is a result of the market accurately pricing in this irreversibility.

Contagion Chain: The $300 Billion Domino That Will Topple Banks, Sovereign Bonds, and Monetary Sovereignty in Succession

The growth of stablecoins is no longer confined to internal events within the cryptocurrency market. A cascading effect is beginning, with ripple effects extending to bank deposits, the sovereign debt market, and the monetary sovereignty of emerging economies.

A contagion cascade is a dynamic where a change in one area, upon exceeding a certain threshold, propagates to adjacent areas at an unexpected rate. Stablecoins surpassing $300 billion signifies the crossing of that threshold.

The first domino is bank deposits.The U.S. Treasury Department estimates that up to $6.6 trillion in bank deposits could flow into stablecoins. The current average U.S. deposit interest rate is 0.39% (0.07% for demand deposits). Meanwhile, cryptocurrency exchanges offer yields of 3.5% or more on stablecoin deposits. This interest rate differential implies a shift to stablecoins as a "rational choice" for individual depositors. Oliver Wyman's analysis asking, "Will Stablecoins Disrupt the Banking Business?" is not a rhetorical question.

The second domino is the U.S. Treasury market. Because the GENIUS Act limited reserves to short-term Treasury bills,If the stablecoin market expands to $1 trillion, a new structural buyer of short-term Treasury bills will emerge, potentially in the hundreds of billions of dollars.According to an analysis by the Brookings Institution, stablecoin issuers purchased approximately $40 billion in short-term Treasury bills in 2024, pushing down the 3-month yield by 2-2.5 basis points. This makes them an "ally" for the U.S. government, helping to finance the fiscal deficit.

The third domino is the currency sovereignty of emerging nations.Over 90% of stablecoins are denominated in dollars, and in Latin America, 71% of respondents use stablecoins for international remittances. An ECB advisor warned that the prevalence of dollar-denominated stablecoins in Europe "replicates patterns observed in dollarized economies." For central banks in emerging markets, the choice between blocking a convenient remittance method or accepting the erosion of monetary sovereignty is a lose-lose situation.

The reason this cascade is unstoppable is that each stage forms a feedback loop that reinforces the next. Bank deposits flow into stablecoins → Demand for U.S. Treasury bonds increases → The U.S. government supports stablecoins → Regulatory legitimacy increases → Even more deposits flow in. Now that this loop has started, reversing individual dominoes means unwinding the entire system.

Intersection of Mechanics

Path dependency and chains of contagion intersect in a mutually reinforcing manner. The institutional choice of the GENIUS method locks in a path, and each time stablecoins grow on that fixed path, the cascading effects on banks, government bonds, and monetary sovereignty expand. Furthermore, each stage of the cascade (banks' entry into stablecoins, the U.S. government's welcoming of demand for government bonds, and the digitalization of the dollar in emerging countries) further entrenches the path.

At the intersection of these two forces lies the historical project of "reinventing the dollar." While stablecoins began as a cryptocurrency innovation, the true engine of their growth lies in their convergence with the U.S. national strategy to extend its currency hegemony into the digital space.

$300 billion is just a milestone. If Standard Chartered's prediction of $2 trillion by 2028 comes to fruition, stablecoins will become a structural pillar of the U.S. Treasury market, and it will be outdated to even discuss them within the "crypto asset" category.

Pattern History

2022: UST/Luna Collapse — The "Death" of Algorithmic Stablecoins Defined the Current Market Structure

In May 2022, the algorithmic stablecoin UST and its sister token LUNA evaporated $45 billion in a week. UST depegged from $1 to $0.20, and LUNA plummeted from $87 to below $0.00005. The unsustainable 19.5% annual yield offered by Anchor Protocol attracted a large influx of funds, and the moment confidence collapsed, a death spiral began: UST redemptions → massive LUNA issuance → LUNA crash → further UST depegging. This incident etched the lesson "stability without reserves does not exist" into the market, effectively eliminating algorithmic stablecoins.

A structural similarity to this time: The UST collapse solidified the path of "only fiat-backed stablecoins surviving," and the GENIUS Act of 2025 legislated that path. Without the crisis of 2022, the legislative justification for 1:1 reserve requirements would not have been obtained. A crisis creates regulation, and regulation fixes the market structure — a typical path-dependency mechanism.

2023: SVB Collapse and USDC Depeg — "Reserves Deposited in Banks Are Not Safe Either"

On March 11, 2023, following the collapse of Silicon Valley Bank, it was revealed that Circle had deposited $3.3 billion (approximately 8% of its reserves) with SVB. USDC temporarily depegged to $0.86, and DAI and FRAX were also affected in a chain reaction. Access to the banking system was unavailable due to the weekend, which amplified the panic. The following Monday, the federal government announced full protection for SVB depositors, and USDC recovered its peg within a few days. This incident demonstrated that "even with adequate reserves, one is not immune to bank risk," and that "government intervention is essential for the stability of stablecoins."

Structural similarities with the current situation: The SVB crisis exposed the interdependence of stablecoins and the banking system, supporting the need for reserve diversification requirements and government oversight as outlined in the GENIUS Act. At the same time, the precedent of "recovery through government intervention" paradoxically strengthened the institutional legitimacy of stablecoins. This is a rare case demonstrating that contagion can also operate "upward."

2024: The Birth of the Eurodollar Market (1957) — A Precedent for Offshore Dollars

The Eurodollar market is said to have originated in 1957 when the Soviet Union, fearing the freezing of its dollar assets in the United States during the Cold War, began holding dollar-denominated deposits in London banks. Because U.S. regulations (Regulation Q) limited domestic deposit interest rates, higher interest rates were offered in unregulated London, and dollars flowed offshore from around the world. By the 1980s, the Eurodollar market had grown to trillions of dollars, fundamentally changing the transmission mechanism of U.S. monetary policy. As a result, the U.S. government came to accept this market not as a "threat" but as an "extension of dollar hegemony."

The structural similarities to this instance: The structural similarities between stablecoins and the Eurodollar market are strikingly high. Both are dollar-denominated financial products born from regulatory loopholes, constructing a "shadow dollar zone" outside the United States. The reason the US government ultimately tolerated (and even supported) this is also the same — anything that expands the use of the dollar strengthens dollar hegemony. The GENIUS Act can be said to be legislation that consciously applies the lessons of the Eurodollar.

Historically observed patterns.

The history of stablecoins is a repeating pattern of "crises determining paths, paths creating institutions, and institutions accelerating cascades." The UST collapse made reserve backing mandatory, the SVB crisis justified government oversight, and the GENIUS Act turned the "digital dollar" into official infrastructure. And the precedent of the Eurodollar market suggests a future where this path is ultimately absorbed as a reinforcement of U.S. hegemony. Reaching $300 billion is not the "completion" of this pattern, but the beginning of its "acceleration."

Future Scenarios

Optimistic Scenario (Probability: 25%)

Driven by the smooth implementation of the GENIUS method and progress in MiCA compliance, the stablecoin market will reach $1 trillion by the end of 2027. Bank participation in stablecoins will increase options for depositors, and international remittance costs will fall to an average of 2% or less. The digital hegemony of the US dollar will be established, reducing the need for CBDCs.

Implications for Investment/Action:A good opportunity to build long-term positions in stablecoin-related stocks (such as Circle) and Ethereum (benefiting as a settlement layer).

Base Scenario (Probability: 55%)

The regulatory framework for the GENIUS method is scheduled to be completed in July 2026 as planned, but competition with banks for deposits has become a political issue. The stablecoin market is projected to grow to $500-700 billion by 2027, but growth will slow due to stricter yield regulations and more stringent KYC requirements. Regulatory compliance disparities between Tether and Circle will trigger a market restructuring.

Implications for Investment/Action:A position focused on USDC/Circle. While monitoring the regulatory risks of Tether, we are paying attention to stablecoins as real-demand assets, leveraging them as infrastructure for international remittances and B2B payments.

Pessimistic scenario (Probability: 20%)

The resurgence of lobbying in bank lobbies has led to stricter enforcement rules for the GENIUS Act, significantly increasing the cost burden on non-bank issuers. Regulations that effectively exclude Tether from the US market have been introduced, temporarily fragmenting liquidity in the stablecoin market. Alternatively, a new depegging event could serve as a pretext for regulatory tightening, stagnating market growth for 2-3 years.

Implications for Investment/Action:Reducing exposure related to stablecoins. Closely monitoring the digital currency strategies of the banking sector and awaiting stabilization of the regulatory environment.

Notable Triggers

• GENIUS Regulatory Compliance DeadlineJuly 18, 2026 — Obligation to define detailed rules within one year of enforcement.
• EU MiCA Full ImplementationJuly 1, 2026 — Full application of cryptocurrency regulations within the EU.
