International payments are a pretty crucial part of trade and remittances, yet the infrastructure behind them is still pretty rooted in the old paper-based system. If you're sending a bank transfer from the States to Kenya, you're probably looking at 3 to 5 days for it to clear, and the cost is a whopping 6.9% of the amount you sent. The World Bank puts the average remittance fee at about 6.5% as of 2025, an awful long way from the G20's target of just 1%. 6.5% 6.5% Payments creep through chains of correspondent banks; each intermediary charges a fee and operates on its own schedule. SWIFT handles messaging but does not move money, and even after upgrades like ISO 20022 and Global Payments Innovation, regulators say end-user benefits remain limited and costs sticky. Frustration with delays and fees has opened the door for alternative rails. What Stablecoins Actually Change Stablecoins are digital tokens that aim to mirror a fiat currency. They're the type of coin that you have, for instance, Circle’s USDC, PayPal’s PYUSD, and USDGO, a U.S. dollar‑backed token launched by Hong Kong‑listed OSL Group. OSL, a stablecoin trading and payment platform in Asia with a global regulatory footprint, initially minted about $50 million in USDGO on the Solana blockchain and plans to expand to other networks. These are typically backed by actual cash and short-term government bonds, and then settled on public blockchains that are always up and running. Circle’s USDC Circle’s USDC PayPal’s PYUSD PayPal’s PYUSD USDGO USDGO $50 million $50 million The International Monetary Fund has pointed out that stablecoins could simplify cross-border transfers and make them cheaper, which is especially true for remittances. McKinsey reckons that 'tokenized cash' lets you get beyond banking's working hours and physical locations, giving you better speed and transparency than what traditional systems have to offer. International Monetary Fund International Monetary Fund McKinsey McKinsey Although stablecoins are still really only getting a tiny piece of the global money action, the amount in circulation has more than doubled, going from 2023 to 2025. As a result, Policymakers are starting to take note: in the US, there's the GENIUS Act, and in the EU, the MiCA regime, both of which would require payment tokens to be 100% backed by high-quality liquid assets and for the issuers to have to be super transparent with their dealings and get proper licenses. With clearer rules in place, Banks, fintechs, and corporate treasurers are beginning to feel more comfortable experimenting. When Payment Giants Enter the Arena Stablecoins are no longer limited to just the crypto world. In 2025, PayPal did something pretty big: they announced that their USD (PYUSD) stablecoin was going to start being used on the Stellar network. The fact that Stellar has such low fees is exactly what they're counting on to make everyday payments, sending money to family members overseas, and lending tiny amounts of cash to people who need it all that much easier. PayPal PayPal They figure the new system will let them serve users in a heck of a lot of countries, over 170 of them. By just tacking a token onto their wallet and how businesses accept payments, PayPal is basically building a road between the folks who do all their banking online and the blockchain. This is all about getting these two worlds to work together. Visa is trying this out through a little project they call Visa Direct: basically, businesses put USDC or PYUSD into special virtual accounts, and their system turns those tokens into good old cash in a heartbeat. Treasurers get to see exactly how much money's in those accounts right this second and can just send the payments straight off in stablecoin form to people's digital wallets. Interestingly, Visa has teamed up with not one but two banks (Cross River and Lead) to get these transactions settled in USDC, which says a lot about how card companies like Visa are starting to see tokens as a useful tool to have on hand. Visa Visa How Stablecoins Compress the Payment Chain The mechanics of a stablecoin transfer cut right through a lot of the hassle that slows things down. A remittance company can collect dollars, then send them over to get converted into USDC. They can then send those tokens over a blockchain, and before you know it, they're putting pesos straight into the recipient's account. remittance company remittance company With fewer middlemen in the picture, fewer fees pop up, and it's a whole lot easier to get everything sorted out. Businesses can route payments over blockchain rails even when both ends of the deal are using local currencies. Often, you won't even know a stablecoin was used. Stablecoins open up some pretty wild new ways of doing finance: you can pay suppliers on demand, make payroll for freelancers on the fly, and even dish out real-time refunds. By 2026, its market cap had already topped out at $300 billion, with billions of low-value transfers happening every month. Sure, it's still pretty small compared to the amount of money that's moving around the world, but you can see the momentum building up fast. $300 billion $300 billion The Risks No One Should Ignore The promised revolution of programmable dollars brings with it some pretty deep-seated system worries. The IMF's warning is that if users start to suspect that an issuer isn't holding onto enough cash, they'll suddenly start pulling their money back out, and this could very well spark a run on that particular currency. IMF's IMF's And that, in turn, could bring about a whole lot of instability. Widespread adoption of programmable dollars could also lead to people swapping out for other currencies altogether, which, in turn, could reduce the control that central banks have over interest rates and other monetary policies. The fact that stablecoin transactions can be anonymous raises a whole host of concerns about money laundering and financing terrorist activities. So regulators are saying basically that stablecoins need to be treated just the same as regular payment systems, and that means subjecting them to a bunch of strict rules and controls. The proposed GENIUS Act wants to make sure that 100% of the money in a stablecoin is backed up by real cash reserves, and that the issuer has to disclose exactly how much cash they've got on hand at the end of every month, and also some new privacy laws in Europe called MiCA proposes that stablecoins will have to be licensed and that the companies that issue them will have to make sure they're managing the risks properly. GENIUS Act GENIUS Act But the problem is that making all of this happen isn't cheap, and having different countries with different rules and regulations makes it really hard to innovate and move forward. The balance that gets struck over the next few years will literally determine whether stablecoins end up being the mainstream way we do business, or if they just keep on operating on the fringes. Rewiring, Not Replacing, SWIFT Stablecoins aren't going to leapfrog SWIFT overnight. The legacy networks have still got a lot to offer - they handle trillions of dollars daily and can offer credit facilities and legal protections that blockchain can only dream of matching, at least for now. However, the payment platforms are getting cleverer; they're actually stringing together transactions across instant payment systems, card networks, and even tokenized cash to find the best way to get the money from here to there. Experts think that by 2027, we'll be seeing around 45% of cross-border payments getting the tokenization treatment. 45% 45% All this is happening against a backdrop where stablecoins are more usefully thought of as a high-tech add-on to the existing financial networks, rather than some kind of replacement for them. What's actually going on here is that reputable players like USDGO, PYUSD, Visa with its pilots, and Circle's infrastructure projects are quietly rewiring the whole way global payments work. If regulators and innovators can find that sweet spot where you get both the safety and speed of the modern financial systems, then maybe just maybe in the end, we'll get to the point where money flows around the world as fast as information all without the hidden costs and dodgy side alleys that we used to have to put up with in the old-fashioned financial plumbing.
