Latest / The Cryptocurrency Economy with Fexingo: Bitcoin, Ethereum, and Digital Money Markets / How Stablecoins Became The Hidden Central Bank
Transcript
- Lucas: If you want to understand where the real power lies in the global economy right now, stop looking at the Federal Reserve building in Washington. Start looking at the reserve ledgers of two private companies based in Zurich and Boston. We are talking about stablecoins, specifically the giants Tether and Circle. Luna: Right, because despite all the noise around Bitcoin mining and AI energy costs, the quiet revolution is happening in the payment rails. These platforms are effectively printing their own version of the US dollar. Lucas: Exactly. And the scale is no longer theoretical. By early October 2026, the combined market cap of major stablecoins had pushed past one hundred thirty billion dollars. That is not just retail speculation. That is enterprise treasury management, cross-border trade settlement, and yes, speculative trading volume. But here is the twist: they are doing it by holding US Treasury bills. Luna: So they are acting like shadow banks? Issuing liabilities against short-term government debt? Lucas: Precisely. When you buy one unit of USDC or USDT, you are essentially lending money to Tether or Circle, and they lend that money to the US government. It is a perfect circular flow of capital, except the middleman takes a spread. In an environment where the Fed Funds effective rate is sitting at 3.75 percent, that spread is incredibly lucrative. It means these companies are earning billions in risk-free interest while offering users near-zero yield. Luna: That sounds like the ultimate arbitrage. They get the yield, the user gets the convenience, and the US government gets a massive buyer for its debt. Why hasn't anyone stopped this? Lucas: Because it is efficient, until it isn't. The problem is what happens when confidence wavers. Unlike a traditional bank, stablecoin issuers do not have FDIC insurance. They do not have access to the discount window. If a rumor spreads that their reserves are not fully backed, there is no lender of last resort. We saw hints of this fragility earlier this year with algorithmic failures, but the bigger risk now is structural. As the ten-year Treasury yield fluctuates, the value of their collateral base shifts. Luna: And if those yields rise too high, the cost of issuing dollar-pegged tokens becomes expensive for them, doesn't it? Lucas: Actually, the opposite. Higher rates mean higher interest income for the issuers. The risk is actually on the other side. If the Fed were to cut rates aggressively, their revenue model shrinks. But let's look at the broader macro picture. With the S&P 500 hovering near record highs and tech stocks like CoreWeave moving violently today, capital is seeking liquidity. Stablecoins provide that liquidity instantly, twenty-four seven, across borders. Luna: But they are also bypassing traditional correspondent banking networks entirely. Visa and Mastercard are trying to integrate crypto, but these issuers are already doing it natively. Lucas: Yes. And this creates a weird dynamic for monetary policy. The Federal Reserve sets the price of money, but Tether and Circle control the distribution. If a country experiences hyperinflation, citizens often flock to stablecoins to preserve wealth. We see this in emerging markets constantly. So, privately held entities are effectively conducting foreign exchange policy for entire nations. Luna: That sounds like a loss of monetary sovereignty for those countries. Is that a problem for the US? Lucas: It is actually a huge boost for dollar hegemony. For the first time, the US dollar is accessible via a simple app wallet rather than a complex banking relationship. It is digital dollarization on steroids. But it raises a question about oversight. Who audits these reserves? Currently, it is largely self-reporting with occasional attestation reports. There is no standardized GAAP compliance for the underlying collateral pool in the same way there is for a regional bank. Luna: So we have a system that is larger than the GDP of many small nations, operating with less transparency than a local credit union. Lucas: That is the headline. And it matters because of the recent headlines regarding China and Mastercard. The US is pressing bilateral talks on market access, but simultaneously, private actors are eroding the need for those traditional gateways. If you can settle trade in Dubai or Singapore using USDC, you do not need Citigroup as much as you used to. Luna: Which makes the regulatory stance even more critical. Are regulators catching up? Lucas: They are trying, but the legislation is lagging. We are seeing state-level frameworks emerge, like the BitLicense in New York, but a federal standard remains elusive. Without a clear rulebook, issuers are playing a game of cat and mouse. Some have moved operations offshore to avoid SEC scrutiny. Others, like Circle, have stayed domestic and embraced compliance, which gives them an edge with institutional clients but exposes them to direct political pressure. Luna: So Circle plays by the rules and Tether flies under the radar? How does the market distinguish between them? Lucas: Increasingly, it does. Institutional investors are demanding higher quality collateral. We are seeing a shift where large corporate treasuries prefer USDC over USDT because of the perceived legal clarity. It is a classic quality flight. When trust is low, people pay for safety. That is why the market share of the two giants is slowly diverging, even if their combined total is still growing. Luna: It reminds me of the subprime mortgage crisis, but inverted. Instead of hiding bad loans, they are hiding lack of transparency behind good ones. Lucas: A great analogy. Because the underlying assets are safe—short-term Treasuries—the systemic risk is lower than it was in 2008. However, the speed of contagion is higher. Crypto markets never sleep. A run on a stablecoin can happen in hours, not days. Liquidity evaporates instantly because the exit ramp is digital and borderless. Luna: Have we seen any stress tests recently? Or is everything too calm? Lucas: Calm is dangerous. The data from late September shows steady inflows into money market funds that back these coins. But look at the volatility in altcoins like Solana or XRP. When those drop, traders flee to stablecoins to wait out the storm. That sudden influx of cash into Tether or Circle stresses their ability to manage redemptions smoothly. They have to buy back their tokens or liquidate reserves rapidly. Luna: Liquidating Treasury bills quickly can impact the bond market, can't it? Lucas: At current volumes, probably not significantly. But imagine a scenario where three or four major stablecoins face simultaneous redemption requests during a broader market crash. That could create a liquidity crunch in the very short-term bond market that the Fed relies on for signaling. It connects the crypto ecosystem directly to the core of American fiscal policy. Luna: That is a terrifying thought. The plumbing is deeper than we think. Lucas: It is. And this brings us to the donation segment. If walking through the economy with us has made something click... Lucas: Honestly, if today was worth a coffee to you, that's the link — buy me a coffee dot com slash fexingo. Luna: Yeah, listener support keeps these deep dives possible without turning every show into an ad read. It lets us dig into the boring stuff that actually moves markets. Lucas: Thanks for keeping the lights on. Now, back to the issue of sovereign backing. If the US government wanted to compete, they would need a Central Bank Digital Currency. Luna: The digital dollar debate is heating up again. Do you think a CBDC would replace stablecoins? Lucas: Unlikely to replace them immediately, but it would change the competitive landscape. A CBDC would offer the ultimate safety net—direct liability of the Federal Reserve. But it would likely come with privacy restrictions that users hate. Stablecoins offer a hybrid: dollar safety with crypto privacy. That is a product-market fit that governments struggle to replicate. Luna: So the competition is between privacy and security. Which side is winning? Lucas: Privacy is winning in the eyes of the consumer, especially in regions with unstable currencies. But in the US and Europe, regulation is tightening the screws. We are likely heading toward a world where only heavily regulated, domestically licensed stablecoins survive. The wild west era is ending. Luna: So consolidation is inevitable? Smaller issuers getting wiped out? Lucas: I think so. The overhead of compliance is becoming prohibitive for smaller players. We will probably see the market consolidate into two or three global giants, each tied closely to a specific jurisdiction. You might see a Euro-backed stablecoin dominating Europe, and a Dollar-backed one everywhere else. Luna: Fragmentation of the dollar itself? Or just fragmentation of the providers? Lucas: Providers. The currency remains the dollar, but the interface changes. And that is why companies like Visa are partnering with Circle instead of trying to build their own coin. They recognize that the infrastructure war is already won by these niche players. Luna: It’s fascinating how the old guard is adopting the new guard's tools to stay relevant. Lucas: Adapt or die. And for investors, the takeaway is clear. Watch the reserve composition. Don't just look at the market cap. Look at what is actually backing the token. If it is commercial paper, run. If it is Treasury bills, breathe easier. But keep your eye on the Fed Funds rate. If those rates drop below two percent, the economics of this whole industry start to crack. Luna: So the health of stablecoins is inversely related to the cost of borrowing for the government? Lucas: Inversely related to the yield available to the issuer. Lower rates mean less profit for Tether and Circle, which might push them to take riskier assets to maintain margins. That is where the danger lies. It is not the collapse of the peg; it is the slow drift into risky collateral as profits shrink. Luna: A subtle creep of risk. Much harder to spot than a sudden crash. Lucas: Exactly. And that is why we need better reporting standards. Until then, we are watching shadows dance on the wall. What do you think? Will Congress force transparency, or will the market simply choose the safest option? Luna: I bet the market chooses safety first, and regulation follows years later. It always does. Lucas: History certainly agrees. But this time, the stakes are higher because the ledger is public, yet the ownership is opaque. We will see.
