Last week, the head of the Bank for International Settlements dropped a warning that caught some attention. Pablo Hernández de Cos basically said that stablecoins could end up making bank loans more expensive. And he's not wrong to worry.

Here's what's actually happening behind the scenes.

The Real Problem for Banks

Banks have had a pretty good run with how they work. You deposit money with them, they lend it out to other people and businesses, and they keep the spread. It's a simple model that's worked for decades. But stablecoins are starting to mess with that.

Right now, there's about $304 billion in stablecoins floating around. That's money that used to be in bank accounts. People are moving their cash into USDT, USDC, and other tokens instead of keeping it in traditional deposit accounts. Why? Because stablecoins can move 24/7, even on weekends and holidays. Banks can't say that. Your bank is closed on Sunday. Stablecoins never close.

The federal reserve actually did a survey. Half of all banks said they're now working on their own stablecoin projects. So banks got the message—either build this stuff or lose customers to someone who will.

Why This Matters for Your Wallet

When deposits move out of banks and into stablecoins, banks lose something they rely on. That money they had sitting in deposit accounts? That was their funding source. They could lend it out and make money. But stablecoins change that completely.

A stablecoin issued by a bank looks different than a regular deposit. The bank can't actually lend against the money backing a stablecoin—it has to sit there as reserves. So if you move $100 million from a regular deposit into the bank's stablecoin, the bank just lost $100 million of lendable funds.

When banks lose cheap funding sources, they need to find funding elsewhere. And when you need to find money in a tighter market, you usually pay more for it. Those costs flow straight through to customers. Your mortgage rates go up. Business loans get more expensive. That's just how the system works.

Adrian Wall, who works on this stuff at the Digital Sovereignty Alliance, put it simply: if stablecoins pull money out of banks rather than cycling it back in, banks face higher funding costs and less ability to hand out credit. That's the chain reaction.

What Banks Are Trying to Do

The banking industry isn't just sitting around waiting to get disrupted. More than 40 banks are launching stablecoins right now. J.P. Morgan has JPM Coin. Société Générale has CoinVertible. Everyone's building something.

But here's where it gets interesting. If every bank launches its own coin, you end up with 40 different tokens floating around. Money gets scattered across small pools. Users have to swap between different coins just to move money from one bank to another. It's messy and inefficient.

That's why 37 European banks got together and created Qivalis. Instead of 37 separate euro stablecoins, they're building one shared version. One pool of liquidity. One coin that works across all their systems. They're targeting a launch in the second half of 2026, if regulators sign off.

The idea makes sense. Banks compete on services—loans, foreign exchange, investment advice. They don't need to compete on basic payment rails. One solid payment system works better for everyone.

What we're watching is the biggest reshuffling of how money moves since maybe the internet itself. Stablecoins aren't a crypto thing anymore. They're becoming a payments thing. They're being used for treasury management, cross-border settlement, payouts to merchants. They're competing with what banks sell.

The warning from the Bank for International Settlements is real. If stablecoins pull deposits out of banks on a large scale, lending will get more expensive and harder to find. That affects mortgages, business loans, everything downstream. But this probably won't be a crash-scenario thing. Banks are adapting. They're building their own versions. They're cooperating on shared infrastructure. The system will shift, but it won't break overnight.

What matters is whether regular customers end up with better payments and lower costs, or whether we just end up with more fragmented systems that don't talk to each other. Time will tell.
