Latest / The Cryptocurrency Economy with Fexingo: Bitcoin, Ethereum, and Digital Money Markets / Stablecoin Flows Are Telling a Story About Liquidity
Transcript
- Lucas: So I want to talk about something that doesn't get as much attention as bitcoin's price moves, but might actually matter more right now — stablecoins. Luna: You mean the fact that total stablecoin market cap just hit a new all-time high above 230 billion dollars? Lucas: Exactly. And that's happening while bitcoin and ether have been basically flat over the past week. Bitcoin's around 77,700, ether at 2,137 — both up less than half a percent in five days. But the stablecoin supply keeps grinding higher. Luna: So the conventional read is that this is dry powder — capital sitting on the sidelines waiting to deploy. But I wonder if that's too simple. Lucas: I think it is, actually. Because if you look at where the supply is growing, it's not just the usual Tether dominance. USDC has added about 8 billion dollars in supply over the past two months. That's institutional money — Circle's product is the one that clears through regulated banks. Luna: Right, and we've seen this pattern before. In early 2024, stablecoin supply expanded for months before the big rally later that year. But it also expanded in late 2022 when prices were falling. Lucas: That's the key nuance. Not all stablecoin growth is bullish for crypto prices in the short term. Some of it is just demand for dollar-denominated yield within crypto — people using stablecoins to earn 4, 5 percent on DeFi lending protocols or on centralized platforms. Luna: Which brings us to the Fed. The effective fed funds rate is at 3.64 percent, and the interest on reserve balances is 3.65. That's flat for the last month. So the risk-free rate outside crypto is still pretty attractive. Lucas: And that's the competition. If you're an institutional treasurer, why take crypto volatility risk when you can get 3.6 percent in a money market fund? But if you're already in crypto, parking funds in USDC or USDT and earning 4 to 5 percent in DeFi starts to look like a real carry trade. Luna: So the stablecoin supply growth might reflect a rational allocation decision — not necessarily impending buying pressure for bitcoin. Lucas: Exactly. And I think the market is mispricing this. A lot of traders see 230 billion in stablecoins and think 'rocket fuel.' But a chunk of that is just earning yield, not waiting to buy crypto. Luna: Do we have a sense of the breakdown? How much is on exchanges versus in DeFi versus in custodial wallets? Lucas: There's data from Glassnode and CoinMetrics that tracks this. Roughly 30 to 35 percent of stablecoin supply sits on centralized exchanges. That's the capital most likely to be deployed into bitcoin or alts quickly. Another 20 to 25 percent is in DeFi protocols — lending pools, liquidity pairs, yield farms. The rest is in wallets, custody, or payment use cases. Luna: So the exchange portion is what I'd watch. If that starts climbing, it's more signal. But right now it's been stable relative to total supply. Lucas: Yeah, the percentage on exchanges hasn't moved much. The growth is happening in DeFi and in institutional custody. That tells me the marginal dollar coming in is yield-seeking, not trade-ready. Luna: I want to pivot to something you mentioned — the institutional angle. We had a headline this week about retail investors getting direct access to the SpaceX IPO through brokerages. That's a different kind of liquidity story. Lucas: It is, and it connects. Because one of the big narratives in crypto has been that institutions are coming. But when you look at where they're actually putting money — it's into stablecoins, not into volatile crypto. They're using the rails, not the assets. Luna: If today's episode was useful to you and you want to keep it ad-free, buy me a coffee dot com slash fexingo helps. Lucas: Yeah, that's literally what keeps the show going. Appreciate everyone who does that. Luna: So back to stablecoins — one thing I find interesting is that this matters beyond crypto. Stablecoins are becoming a real part of the dollar system. There's now more USDC in circulation than some small-country GDPs. Lucas: And the Fed is paying attention. We had that speech from a Fed governor last month about the regulatory framework for payment stablecoins. The tone was cautious but not hostile. They see the efficiency gains but worry about runs. Luna: Right, because if a stablecoin breaks its peg, it could ripple into short-term credit markets. Circle holds most of its reserves in Treasury bills and reverse repo — that's high quality, but it's still a liquidity transformation. Lucas: And that's why I think the stablecoin story is actually more consequential for macro than the bitcoin price story. It's about how dollars move globally. We've seen usage in Latin America, Africa, parts of Asia where people use USDT as a savings vehicle because they can't get dollars from their local banks. Luna: So the 230 billion number — it's not just crypto speculation. It's dollar demand from places the traditional banking system doesn't serve. Lucas: Exactly. And that demand is structural. It's not going away if bitcoin goes to 60,000 or 100,000. That's a separate use case. Luna: So if I'm an investor listening, what's the actionable takeaway? Should I care about stablecoin supply as a leading indicator? Lucas: I think you should monitor it, but don't treat it as a simple buy signal. Watch the composition — is exchange supply rising? Are DeFi yields compressing relative to Treasury yields? If DeFi yields drop because of more supply, that capital might rotate into volatile assets. But right now the spread is still attractive. Luna: And the Fed isn't cutting anytime soon, so the opportunity cost of holding stablecoins is low relative to history. Lucas: Right. The bottom line: stablecoins are a window into where liquidity is flowing in the crypto economy. And right now, it's flowing toward yield, not toward speculation. That could change quickly, but for now, the market is telling us something more boring — and maybe more important — than a rocket ship. Luna: I like that framing. Next episode, I want to dig into Solana's recent price action — it's up almost 3 percent this week while everything else is flat. Something might be stirring there. Lucas: Noted. We'll have a look at the data.
