Hey RafiOnChain here. And I want to tackle something that dropped this week that I think deserves a proper breakdown rather than the usual crypto Twitter pile-on.

On May 26th the Wall Street Journal published a piece by Greg Ip, their chief economics commentator, titled "Stablecoins Are Private Money. That's Why They're a Risk to the Economy." It immediately set off a firestorm. Coinbase executives fired back within hours. The Bank Policy Institute amplified it. The BIS General Manager was quoted in support of it. And the debate landed right in the middle of the GENIUS Act and CLARITY Act legislative moment.

I want to walk through the actual argument, the actual counterargument, and then give you my honest read. Because this matters for everyone in crypto, not just stablecoin holders.

What Greg Ip Actually Argued

Let me give you the substance of the WSJ piece because most of the takes online have been reacting to the headline rather than the argument.

Ip's core claim is that stablecoins are a form of privately issued money and that privately issued money has a long and problematic history. He drew two specific historical comparisons. The 19th-century free banking era in the United States when private banks issued their own banknotes backed by assets of varying quality and reliability. And the 2008 money market fund crisis when the Reserve Primary Fund broke the buck, meaning its net asset value fell below $1 per share, triggering a run that required a government backstop to stop.

His specific concern about stablecoins has three layers.

First, the reserve risk. Stablecoins are backed by assets like Treasury bills that must be sold to redeem coins one for one at par. CoinMarketCap puts total stablecoins outstanding at roughly $300 billion, led by Tether at $190 billion and Circle at $76 billion. If a large-scale redemption event hits, issuers would be forced to rapidly liquidate their Treasury reserves. The IMF specifically warned in its October financial stability report that this forced selling could create spillover effects in broader bond markets. Concentrated Treasury selling pressure from a $300 billion stablecoin sector is not a hypothetical. It is a structural risk that scales with adoption.

Second, the yield-chasing risk. Ip warned that stablecoin issuers could eventually face incentives to reach for yield by holding riskier reserve assets. The profit model for a stablecoin issuer is simple. You collect $1. You hold that dollar in Treasuries earning the risk-free rate. You keep the yield. If Treasury yields compress, the temptation to move into higher-yielding but riskier assets increases. That is exactly what happened with money market funds before 2008. The Reserve Primary Fund held Lehman Brothers commercial paper chasing slightly better yields. When Lehman collapsed the fund broke the buck. Ip is drawing a direct line between that dynamic and the potential future behavior of stablecoin issuers under margin pressure.

Third, the singleness of money problem. This is the most philosophical but also arguably the most important point. The principle that one dollar always equals one dollar everywhere in the financial system is what economists call the singleness of money. It is not obvious. It requires infrastructure. In the US that infrastructure is the Federal Reserve settlement system, deposit insurance, and regulatory oversight. Ip and BIS General Manager Pablo Hernández de Cos both argue that stablecoins attempt to import credibility from public money while operating outside the established settlement system. The quote from De Cos that Ip used is worth sitting with. Stablecoins attempt to import credibility from public money while operating outside the established settlement system.

What Coinbase Fired Back

Coinbase Chief Policy Officer Faryar Shirzad posted a detailed response on X within hours of the WSJ piece publishing.

His central counterargument was direct. Approximately 90% of the US M2 money supply is already privately issued. Commercial bank deposits are private money. The question is not whether money is public or private. The question is whether regulation adequately manages the associated risks. Private money is already the norm. The WSJ's framing treats the novelty of stablecoins as the risk when the existing system is already dominated by privately issued money that most people never think about.

On the GENIUS Act specifically, Shirzad argued that the legislation directly addresses every specific risk Ip identified. The GENIUS Act prohibits stablecoin issuers from lending out reserves or using leverage, eliminating the bank run risk from asset-liability mismatches. It requires a strict 1 to 1 reserve ratio backed exclusively by cash and short-term US Treasuries. It prohibits fractional reserve banking entirely. It requires public disclosure of reserve composition. It mandates redemption at par within defined timeframes. And importantly, the GENIUS Act was signed into law last year. These are not theoretical future safeguards. They are current law for regulated US stablecoin issuers.

Shirzad's pointed line: "Private money isn't the exception in our system. It's the rule." He added that GENIUS stablecoin issuers would be prohibited from engaging in bank-like activities such as lending. The risk Ip is describing, the reach-for-yield behavior, is explicitly banned under legislation that is already on the books.

Where Both Arguments Have Merit

Here is my honest assessment and where I think each side is right and where each side is glossing over something important.

Ip is right that regulatory compliance is not the same as risk elimination. The WSJ piece specifically noted that loopholes remain through offshore stablecoins and reward programs even after the GENIUS Act. Tether, which represents $190 billion of the $300 billion total, is issued by a company incorporated in the British Virgin Islands and operates primarily outside US regulatory jurisdiction. The GENIUS Act governs US-regulated stablecoin issuers. It does not govern Tether. When Ip says no legislation can fully remove risk that is intrinsic to the design of stablecoins he is partly pointing at this offshore gap. A coin run on Tether is a systemic event regardless of what US law says about Circle's USDC reserves.

Ip is also right that the historical precedents are real. The 19th century free banking era did produce bank runs. The 2008 money market crisis did require a government backstop. Financial innovation does routinely produce excesses that lead to sudden losses of confidence. That is not a theoretical argument. It is empirical history.

Coinbase is right that the GENIUS Act's 1 to 1 reserve requirement and prohibition on lending fundamentally changes the risk profile compared to fractional reserve banking. A stablecoin backed 100% by short-term Treasuries cannot break the buck the way a money market fund holding commercial paper can. The asset quality is different. The leverage is different. The structural run risk is lower.

Coinbase is also right that the private money framing, while technically accurate, creates a misleading impression of novelty. The entire commercial banking system is private money creation. Every bank deposit is a privately issued claim on a dollar that only exists because of fractional reserve banking and deposit insurance backstops. If private money creation is the risk, the risk has existed for 150 years and the system has survived it with appropriate regulation.

The Number That Puts It in Context

Total stablecoin market cap has grown to over $300 billion as of mid-2026, up from around $150 billion at the start of 2025. Stablecoin transaction volumes for 2025 surpassed $30 trillion according to the European Central Bank report published in May. That is larger than Visa and Mastercard combined.

That scale changes the systemic relevance calculation. When stablecoins were a $50 billion niche the systemic risk argument was theoretical. At $300 billion with $30 trillion in annual transaction volume and growing integration with traditional financial infrastructure, the argument becomes more concrete. Saudi Arabia is building stablecoin settlement into its national real estate infrastructure. Morgan Stanley clients are accessing Bitcoin through regulated ETFs. The integration with traditional finance is accelerating faster than the regulatory framework is adapting.

Fed Governor Michael Barr gave a speech in April 2026 that preceded the WSJ piece and set the tone for the regulatory concern. His exact words: "Caution is warranted because we have a long and painful history of private money created with insufficient safeguards." That is not fringe concern. That is the Federal Reserve governor speaking on the record about systemic risk from stablecoins months before the WSJ published its piece.

What the GENIUS Act Actually Does and Does Not Do

Since this is the central policy document in the debate it is worth being precise about what it covers.

The GENIUS Act signed into law last year establishes a federal regulatory framework for payment stablecoins. It requires 1 to 1 backing with high quality liquid assets including US currency, Treasury bills with maturities of 93 days or less, central bank reserves, and certain repurchase agreements. It prohibits issuers from lending reserves or creating fractional-reserve liabilities. It requires monthly public disclosure of reserve composition verified by a registered accounting firm. It creates a dual federal and state licensing pathway.

What it does not do is regulate offshore stablecoin issuers operating outside US jurisdiction. It does not retroactively change the reserve composition of existing issuers during a transition period. It does not create deposit insurance for stablecoin holders. And it does not address the systemic risk from a large-scale simultaneous redemption event if market panic drives everyone to redeem at once regardless of whether reserves are adequate, because the speed of redemption at scale can itself create market stress even when underlying assets are sound.

That last point is the most technically subtle part of the debate. Even a perfectly backed stablecoin can create Treasury market stress if a large enough redemption wave forces simultaneous liquidation of Treasury positions into an already stressed bond market. The adequacy of reserves does not eliminate the market impact of forced selling.

My Honest Take

I use stablecoins. I am guessing most people reading this do too. They are genuinely useful. Cross-border transfers in minutes for fractions of a cent instead of days for significant fees. On-chain settlement that does not depend on banker's hours. A stable unit of account for DeFi operations. The utility is real and the WSJ piece does not seriously dispute it.

But the WSJ piece is not crazy. Ip is not a crypto-illiterate making uninformed claims. He is a serious economics journalist drawing on real historical precedents and making a specific structural argument about how financial innovations that start benign can evolve in ways that create systemic fragility. That argument deserves a serious response and the crypto industry's best response is the GENIUS Act's specific provisions, not dismissal.

The honest position is somewhere in the middle. Stablecoins with strict 1 to 1 reserve requirements, no lending, and full public disclosure are substantially safer than the historical private money experiments Ip cited. But the offshore gap, the systemic scale of forced Treasury liquidation risk, and the speed-of-run dynamics in a digital environment are genuine residual risks that regulation has not fully solved.

The debate landed at the right moment. The GENIUS Act is law. The CLARITY Act just passed the Senate. The regulatory infrastructure is being built. Whether it is being built fast enough and comprehensively enough to match the $30 trillion annual transaction volume is the real question.
