Stablecoins may be the weak link in crypto’s decentralization promise
Bitcoin can move value without asking a bank for permission. Stablecoins usually cannot. A February 2026 report from CEPR and LTI@UniTo argues that this is where crypto’s cleanest narrative starts to get messy: Bitcoin has genuinely pushed finance toward decentralization, but stablecoins bring back the intermediaries and trust frictions blockchain was supposed to remove.
- Bitcoin is natively decentralized; stablecoins are issuer-dependent
- “Fully backed” does not mean stress-proof
- Reserve quality matters more than marketing copy
- South Korea could become a live test case
The report asks a blunt question: can blockchain truly decentralize money, contracts, and finance, or does it mostly reshuffle trust into new packaging? Its answer is sympathetic to Bitcoin, skeptical of stablecoins, and allergic to hype.
Led by Bruno Biais of HEC Paris, the analysis treats Bitcoin as a real technological break from legacy payments. The network prevents double-spending without a central operator, and the report says it is supported by tens of thousands of nodes globally. It also notes that the system reaches consensus roughly every 10 minutes, which is the mechanism that lets the ledger keep moving without a payments boss sitting at the top of the pyramid. For readers who want the nuts and bolts, How does Bitcoin work? is still the cleanest plain-English explainer.
That matters. It means no bank, government, or corporate issuer needs to approve each transfer. Bitcoin does not need a permission slip to exist. That is not a small thing, and it is why the asset still matters even after a decade of people declaring it dead, useless, or one regulatory headline away from extinction.
The report also leans into a classic monetary economics point: money, whether it is Bitcoin or fiat, depends on shared belief. It describes money as a “belief-backed bubble” and quotes Jean Tirole:
“Bitcoin is a pure bubble and if trust disappears its value goes to zero.”
That sounds like a knockout punch until you remember the report’s own counterpoint: the same logic applies, in theory, to fiat currencies like the dollar and the euro. The difference is that fiat has a sovereign backstop. States can tax, enforce legal tender rules, and use institutions to stabilize acceptance in a crisis. Bitcoin has no such backstop. It has protocol rules, mining incentives, market liquidity, and network consensus. Different machinery, different trade-offs.
That is the real split. Fiat is politically anchored. Bitcoin is cryptographically anchored. One relies on state power. The other relies on distributed trust and economic incentives. Neither is magic, which is why money remains one of humanity’s most overconfident inventions.
Where the report turns sharply critical is stablecoins. It calls them an “inverse” of decentralization, and the phrase lands because stablecoins are not decentralized assets in any meaningful native sense. They are centrally issued claims. Users have to trust the issuer, the issuer’s governance, its custody choices, and its redemption policy. That is not trustless money. That is tokenized liability with blockchain cosmetics. A Stablecoin, in plain language, is only as solid as the promises behind it.
Stablecoins are also useful. That is the awkward part. They play a major role in trading, cross-border transfers, and on-chain settlement because they reduce volatility relative to Bitcoin or Ether. But utility does not erase structure. A stablecoin can be practical and still be fragile as hell when confidence weakens.
The report’s central worry is run risk, what happens when many users try to redeem at once and the issuer must meet those claims quickly. That gets ugly if reserves are concentrated in places that are hard to liquidate under pressure, or if the issuer can slow redemptions, impose fees, or limit withdrawals when things get tense. For a sharper critique of that problem, see Academic Report Warns Stablecoins Reintroduce Risk Despite.
The 2023 Circle and Silicon Valley Bank episode is the clearest example in the material. The report cites roughly $3.3 billion of USDC reserves held at SVB. That is the kind of reserve concentration that looks fine right up until it does not. If part of a token’s backing is sitting inside a fragile bank, then the “stable” part depends on a chain of confidence that can crack very quickly.
The report also points to Tether’s USDT and its reported large holdings of U.S. Treasuries. Treasuries are generally considered liquid, but they are not magic cash piles in a panic. If an issuer has to raise a lot of money quickly, scale matters, market depth matters, and settlement timing matters. Liquidity is only comforting until everyone wants it at once.
That is why “fully backed 1:1 reserves” is necessary but not sufficient. A stablecoin can advertise full backing and still be exposed to the wrong kind of backing: bank deposits, slow-to-sell assets, concentrated custody, or redemption terms that push the pain onto users. The real question is not just whether reserves exist. It is where they sit, how fast they can be converted, and whether holders have legally enforceable redemption rights under stress.
The report is also skeptical of stablecoins as everyday money. It sees more promise in crypto as a store of value, especially in countries where central bank credibility is weak or inflation risk is high. Bitcoin can serve that role because its supply is not managed by a government and it cannot be inflated away by policy committees with a fondness for dilution and a fear of headlines.
It is less convincing as a medium of exchange for small purchases. The report cites El Salvador’s Bitcoin legal tender experience as a cautionary example for small-ticket transactions. That tracks with common sense: people buying coffee and groceries want something fast, stable, and boring. Volatility is a terrible feature for checkout lanes.
Bitcoin may be better understood as a store of value and settlement rail than as a daily spending currency. That is not a failure. It is a product fit question. Demanding that Bitcoin behave like card payments is like asking a steel beam to moonlight as a pillow.
Stablecoins and Bitcoin are often lumped together under the crypto umbrella, but the report makes a useful distinction that too many shillers blur. Bitcoin removes the trusted intermediary at the protocol level. Stablecoins do not. They replace one trust stack with another one, usually centered on an issuer and its financial plumbing. That can be efficient. It is not decentralized. Those are different claims, and only one of them survives contact with reality.
The policy angle gets sharper in South Korea, where a won-denominated stablecoin has entered debate around the Korea’s 2026 Crossroads in Digital Asset Regulation. If the point is to improve cross-border settlement, the report argues that the country would need more than a shiny token and a press release. It would need blockchain infrastructure, reserve disclosure standards, liquidity requirements built for stress scenarios, and redemption rules that are actually enforceable.
That last part matters more than most marketing decks admit. The report’s core point is not simply that a stablecoin should be backed 1:1. It is that the issuer matters. A bank-backed or corporate-issued won stablecoin still carries issuer risk, reserve risk, and redemption risk. If policymakers want stability, they have to design for the ugly day, not the calm one.
The report also mentions broader regulatory efforts, including the European Union’s MiCA framework and the U.S. GENIUS Act, as signs that authorities are trying to box stablecoins into something safer. That may help. It may also prove insufficient once a real stress event hits. Rules on paper are not the same as surviving a market-wide redemption stampede. The EU’s consultation on MiCA’s review, including climate and broader market impacts, is part of that same bureaucratic grind: Understanding the Impact of Climate Change on Global.
And that is the part people keep trying to sand down. If redemption is fast but reserves are not fully liquid, you have a liquidity mismatch. If a few issuers dominate the market, you have concentration risk. If redemptions can be delayed, limited, or fee-gouged under pressure, you have run dynamics. Call it innovation if you want, but banking history already has a name for this movie. South Korea is already wrestling with these tensions in a very real way, as seen in Korea's Stablecoin Future: Bank-led Stability vs. and South Korea’s Crypto Overhaul: Stablecoins and Deregulation.
None of that means stablecoins are useless. They are not. They are extremely useful. But they are useful for the same reason they are fragile: they are private liabilities with a promise attached. That is a powerful tool, and a vulnerable one.
Bitcoin, by contrast, is doing something more fundamental. It has shown that value can move without a central operator and without a sovereign issuer. That does not make it perfect. It remains volatile, and it still depends on belief, incentives, and market structure. But it is a real decentralization gain, not just a branding exercise. The contrast looks even starker when you see how states treat seized coins: witness South Korea Sells $23.5M in Seized Bitcoin: Security.
So the cleanest takeaway is this: Bitcoin has proved that money can be credibly decentralized at the protocol level. Stablecoins have proved that old financial risk can be wrapped in a new user interface. Sometimes the innovation is genuine. Sometimes it is just finance with a shinier helmet. And sometimes, as ugly as it sounds, crypto-related trust can turn deadly in the real world, as shown by South Korea Bitcoin Dispute Turns Deadly: Partner Accused.
Key questions and takeaways
-
Are Bitcoin and fiat both dependent on belief?
Yes. Bitcoin depends on network trust, incentives, and market adoption. Fiat depends on public trust plus a sovereign backstop such as taxation power, legal tender rules, and state institutions. The broader question of whether blockchain can really decentralize money, contracts, and finance is explored in the CEPR paper, Error extracting content. -
Why is the report more favorable to Bitcoin than to stablecoins?
Because Bitcoin reduces reliance on trusted intermediaries at the protocol level, while stablecoins reintroduce issuers, custodians, reserve managers, and redemption policies. -
What is the biggest risk with stablecoins?
Run risk. If many holders redeem at once and the reserves are not liquid enough, the peg can come under pressure even when the token looks “fully backed” on paper. -
Why does reserve transparency matter so much?
Because the quality of backing matters as much as the amount. Users need to know where reserves sit, how cashable they are under stress, and what legal redemption rights they actually have. -
Is Bitcoin better for payments or savings?
The report leans toward savings and settlement. Bitcoin can move value without censorship, but its volatility makes it awkward for small everyday purchases. -
What should South Korea get right if it pushes a won stablecoin?
It would need strong blockchain infrastructure, reserve disclosure standards, liquidity rules built around stress scenarios, and redemption governance that is legally enforceable, not just politically convenient.
