Stablecoins Hit $308B as SVB’s Shock Still Echoes

U.S. dollar stablecoins reached about $308 billion, while SVB’s failure reshaped USDC reserves.

U.S. dollar stablecoins added $71 billion since April 2025, pushing total market value to about $308 billion. The New York Fed’s latest Liberty Street Economics post says the biggest lesson is still the same: shocks outside crypto can change stablecoin reserves fast.

The authors — Pablo D. Azar, Sean Baker, Marco Cipriani, and their coauthors at the New York Fed — use the 2023 Silicon Valley Bank failure as a case study. Their point is simple: stablecoins may live on blockchains, but their reserve assets still sit in money markets, repos, and bank accounts.

Stablecoins kept growing after the last Fed update

The growth story is easy to miss because stablecoins are often discussed only when something breaks. This update shows the market kept expanding after the Fed’s April 2025 post, and the increase was large enough to matter on its own.

The market added $71 billion in less than a year. That 30 percent jump took the U.S. dollar stablecoin sector to about $308 billion, which is no longer a niche corner of crypto plumbing.

That growth also happened after the GENIUS Act passed in July 2025, creating the first federal framework for payment stablecoins. The article treats that timing as important, even if the law is not the whole explanation for the rise.

• CoinGecko data in the post shows the market’s recent expansion clearly.
• Tether and USDC still dominate the sector.
• The two largest issuers account for more than 80 percent of industry assets.

SVB changed how USDC holds reserves

The more interesting part of the update is not the size of the market. It is what happened when a traditional banking shock hit a stablecoin issuer’s reserve stack.

On March 11, 2023, Circle said about 8 percent of USDC reserves were parked at SVB, which had entered FDIC receivership the day before. USDC then traded below $1.00 in the secondary market and saw clear outflows.

The New York Fed authors then track the Circle Reserve Fund, the money market fund that holds most of USDC’s reserves. By March 2026, the fund accounted for about 86 percent of USDC reserves, so changes there matter a lot.

“The collapse of Silicon Valley Bank highlighted the importance of the composition of stablecoin reserves,” the authors write in the post.

That sentence gets to the core of the article. Stablecoin risk is not just about whether a token is pegged to a dollar. It is also about what backs the token and how quickly that backing can be rearranged after a shock.

Interest-rate risk fell, counterparty risk changed

The authors use weighted average maturity, or WAM, to measure interest-rate sensitivity inside the Circle Reserve Fund. Before SVB failed, the fund’s WAM was above the median Treasury-only money market fund.

After the bank failure, the pattern flipped. The CRF’s WAM dropped below the median Treasury-only fund and stayed below the 5th percentile of the Treasury-only distribution. In plain English, Circle pulled back from interest-rate risk and moved into shorter-duration assets.

The fund also changed its repo exposure dramatically. Repo holdings went from zero to more than 90 percent of net assets after SVB’s collapse, then settled at 69 percent later on. That is a major portfolio rewrite, not a small rebalance.

• WAM fell below the Treasury-only median after March 2023.
• Repo holdings rose from 0 percent to more than 90 percent of net assets.
• Repo holdings were still 69 percent by the later reporting period.

There is another twist here. The repo book itself changed counterparties over time. Starting in late 2024, the share of Fixed Income Clearing Corporation sponsored repos rose quickly and reached 77 percent by 2025:Q4.

That matters because the reserve portfolio is no longer just a pile of safe assets. It is a chain of exposures to banks, clearing institutions, and funding markets. When one link moves, the rest can move too.

USDC and USDT now show two very different models

The article’s comparison between USDC and USDT is useful because it shows how different stablecoin designs can be in practice. Both aim to track the dollar, but their reserve mixes look very different.

USDC’s attested reserves are mostly cash and short-term U.S. government securities. USDT’s attested reserves, by contrast, included corporate bonds, gold bars, Bitcoin, secured loans, and other investments that made up nearly 24 percent of reserves as of December 2025.

That difference is not cosmetic. It changes how each issuer might react to stress, how liquid the reserves are, and what kind of market shock could hit the peg first.

• USDC leans toward cash and short-term government paper.
• USDT includes a wider mix of non-cash assets.
• The top two issuers still control more than 80 percent of the market.

The article also reminds readers that stablecoins are now tied to traditional financial plumbing in a way that regulators cannot ignore. Money market funds, repos, and bank deposits are not side details; they are the core of the asset side.

What this means for 2026

The clean takeaway is that stablecoin growth is continuing, but reserve risk has not gone away just because the market got bigger. If anything, the links between crypto tokens and non-crypto funding markets are clearer now than they were in 2023.

If Circle, Tether, and other issuers keep scaling, the next stress test may come from outside crypto again: a bank failure, a repo market shock, or a sharp move in short-term rates. The important question for 2026 is whether reserve transparency and asset mix can keep pace with that growth.

For readers tracking stablecoins as market infrastructure, the number to watch is not only market cap. It is the composition of reserves, the concentration of issuers, and how quickly those reserves can be reshaped when pressure hits.
