Latest / The Cryptocurrency Economy with Fexingo: Bitcoin, Ethereum, and Digital Money Markets / Why Stablecoin Yields Are Outperforming Traditional Treasuries
Transcript
- Lucas: So we've been talking a lot about stablecoins on this show — their role in trading, in remittances, as a store of value in volatile markets. But there's a quieter trend that's been building all year, and I think it's worth drilling into. Luna: What's that? Lucas: Stablecoin yields are beating traditional Treasury bills. I mean, consistently, week over week. Right now, with the Fed funds rate sitting at 3.63 percent — basically flat for months — you can deposit USDC on Aave and earn over 5 percent. That's a spread of nearly 140 basis points. Luna: And that's not just a flash in the pan. I've been watching this since Q1. The spread has actually widened since the Fed paused. Lucas: Exactly. And it's not just Aave. Compound is offering similar rates on USDC and USDT. Even some centralized platforms like Nexo and Crypto.com are paying north of 4 percent. But the really interesting part is why these yields exist in the first place. It's not magic — it's structural. Luna: Walk me through the mechanics. How can a protocol pay more than the US government? Lucas: Right. So in traditional finance, a Treasury bill yields the risk-free rate — basically what the Fed sets, adjusted for duration. In DeFi, the yield comes from borrowers willing to pay a premium to access stablecoins. Those borrowers are often leveraged traders, arbitrageurs, or protocols needing liquidity for flash loans. They're paying 6, 7, sometimes 8 percent to borrow stablecoins, and the lending pool splits that revenue among depositors. Luna: So the spread comes from demand for leverage in crypto markets. That's not necessarily sustainable if trading volumes drop. Lucas: That's the key question. But so far in 2026, on-chain lending volumes have held up pretty well. Bitcoin at 64,000, Ethereum at 1,820 — not exactly booming, but not dead either. And the demand for leverage seems structural at this point. A lot of professional traders prefer to borrow in stablecoins rather than sell their crypto and trigger tax events. Luna: That makes sense. So the yield is essentially a tax-arbitrage premium. But what about the risks? We've seen stablecoins de-peg before. Lucas: Absolutely. The biggest risk is smart contract failure. If Aave or Compound gets exploited, depositors could lose funds. There's also de-pegging risk — if USDC or USDT loses its dollar peg, the yield becomes meaningless. And there's regulatory risk. The SEC and Treasury have been circling stablecoins for years. If they impose reserve requirements that cap yields, this whole model could change. Luna: But for now, the market is voting with its dollars. Total value locked in stablecoin lending protocols is up about 30 percent year-to-date, isn't it? Lucas: Yeah, roughly. According to DeFi Llama, TVL in stablecoin lending is around 18 billion dollars as of this week — that's up from about 14 billion in January. And a lot of that is institutional money. Hedge funds, market makers, even some corporate treasuries are allocating a portion of their cash to these pools. Luna: Because 5 percent is 5 percent. And when T-bills are yielding 3.6, the incremental return is real, especially at scale. Lucas: Right. A 140-basis-point pickup on a 10-million-dollar allocation is an extra 140 grand a year. That's not trivial. And the friction to enter is lower than it used to be — companies like Circle and Coinbase have made it easy to move between USD and USDC. Luna: But what about the argument that these yields are just a reflection of crypto's inherent risk? That they'll collapse when the next bear market hits. Lucas: It's a fair concern. In 2022, when crypto markets crashed, stablecoin lending rates did dip, but they didn't go to zero. Borrowing demand actually increased in some cases — people wanted leverage to buy the dip. So it's not perfectly correlated with price. But if we enter a prolonged bear market where trading activity dries up, yields would likely compress. Still, even then, they might remain above T-bills because the borrower base is different. Luna: Different how? Lucas: T-bill buyers are mostly banks, pension funds, foreign governments — they're buying for safety and liquidity. The people borrowing stablecoins are actively using the capital for trading, arbitrage, or yield farming. They're willing to pay higher rates because they expect to earn even more on the other side. So the yield is tied to the opportunity cost of capital in crypto, not just the risk-free rate. Luna: That's a crucial distinction. And it suggests that stablecoin yields could remain elevated even if the Fed cuts rates. Lucas: Exactly. If the Fed cuts to 3 percent, T-bill yields drop, but stablecoin yields might only fall to 4.5 or 5 — the spread widens. That's actually what we saw in 2024 and 2025. Each time the Fed paused or signaled a cut, DeFi yields didn't fall as much. The correlation is there, but it's not one-to-one. Luna: So for an investor looking for income, stablecoins are becoming a real alternative. But you need to be comfortable with the tech risk and the regulatory uncertainty. Lucas: Right. And there's one more factor that's often overlooked: the tax treatment. In the US, crypto interest is generally taxed as ordinary income, not as qualified dividends. So the after-tax yield might be closer to T-bills after accounting for state and local taxes. But that's a conversation for another episode. Luna: We could do a whole episode on crypto tax quirks. But I want to come back to the bigger picture. If stablecoin yields are structurally higher, does that change how we think about the role of crypto in a portfolio? Lucas: I think it does. Historically, crypto was seen as a pure risk asset — you buy it for appreciation. But stablecoin yield products are creating a new fixed income like asset class. Some portfolio managers are starting to allocate a small percentage — maybe 2 to 5 percent — to stablecoin lending as a cash alternative. It's not quite 'risk-free', but for investors who understand the risks, the yield pickup is attractive. Luna: And it's not just retail. I've seen reports that some endowments and family offices are dipping their toes in. Lucas: Yeah, the University of Michigan endowment hasn't done it, but there are a few smaller ones. The key barrier is custody and operational complexity. But as platforms like Coinbase Prime and BitGo offer institutional-grade stablecoin yield products, that barrier is lowering. Luna: Alright, so let's zoom out. If stablecoin yields remain elevated, what does that mean for the broader crypto economy? Lucas: One implication is that stablecoins become an even more important on-ramp. People and institutions park cash in stablecoins to earn yield, and that cash is then available to deploy into other crypto assets quickly. It lowers the friction of moving in and out of the market. Another is that it creates a natural demand for stablecoins themselves — which strengthens their peg and their network effects. Luna: So it's a virtuous cycle. More yield attracts more capital, which strengthens stablecoins, which attracts more yield seekers. Lucas: Exactly. But there's a potential dark side. If yields get too high, it could encourage excessive leverage. And if a major stablecoin de-pegs, it could trigger a cascade of liquidations. We saw that with Terra in 2022 — though that was an algorithmic stablecoin, not a fiat-backed one like USDC. Luna: Right. The fiat-backed stablecoins are more resilient, but they're not immune to bank runs. If Circle or Tether ever faced a redemption crisis, the fallout would be enormous. Lucas: And that's why regulators are paying attention. The stablecoin bills circulating in Congress would require full reserve backing and regular audits. If those pass, it could actually legitimize the space and make institutional investors more comfortable. But it could also cap yields if they impose restrictions on how reserves can be invested. Luna: So we're in a holding pattern. The market is enjoying these yields, but the regulatory sword of Damocles is still hanging. Lucas: Speaking of which, I want to be transparent about something. This podcast is ad-free and listener-supported. A handful of listeners chip in monthly through Buy Me a Coffee — that's buy me a coffee dot com slash fexingo — and that's literally what funds making this many episodes possible. If you've gotten value from our conversations, that's the way to keep it going. Luna: Yeah, it's a small group, but it makes a huge difference. And it keeps us independent — no sponsors dictating topics. Lucas: Exactly. So back to stablecoins — the bottom line is that the yield spread with T-bills is real, it's structural, and it's attracting serious capital. But it's not without risk. The smart money is watching the regulatory landscape and the health of the underlying protocols. Luna: And for the average listener, if you're curious about earning yield on your stablecoins, start small, use a reputable platform, and never invest more than you can afford to lose in a smart contract hack. Lucas: Good advice. Next episode, we'll look at how Ethereum's fee burn is interacting with staking yields — it's getting interesting again.
