I spent three years thinking I understood what stablecoins were for. I was wrong.
It took a single conversation — a deep dive into Visa’s Latin America strategy — to realize that the entire narrative around stablecoins as a threat to national payment systems is a comfortable fiction we tell ourselves. The truth is far more pragmatic, and far more instructive.
Last week, Antônia Souza, Visa’s Head of Digital Currency for Latin America, sat down with a local outlet and said something that should make every crypto evangelist pause: stablecoins are not here to compete with Brazil’s PIX. They are here to complement it. The statement was direct, almost dismissive of the FOMO-inducing headlines we see daily. But beneath that calm assertion lies a blueprint for how blockchain assets will actually integrate into the mainstream — and it bears almost no resemblance to the 'banking the unbanked' sermon we keep hearing.
I’ve been building in crypto education since 2017, and I’ve audited enough whitepapers to know that the gap between 'what we claim' and 'what we deliver' is where the real story lives. Souza’s interview is a rare window into that gap. Let me unpack what she actually said, and why it matters more than any Layer 2 hype.
First, the context. PIX is Brazil’s instant payment system, launched by the central bank in 2020. It’s fast, free, and ubiquitous — over 70% of Brazilian adults use it. Any narrative that frames stablecoins as a direct competitor to PIX is a misunderstanding of both the technology and the market. Souza made this explicit: stablecoins are not for buying coffee. They are for cross-border remittances and dollar-denominated savings. The crypto-native crowd might wince at this limited use case, but that is precisely why Visa is winning.
Here’s the core insight: stablecoins solve a specific, high-friction problem — moving value across borders efficiently — while leaving the low-friction, high-volume domestic payment space to national systems like PIX. This is not a weakness. It’s the most viable path to adoption. Visa’s own numbers back this up: they’ve processed over $7 billion in annualized stablecoin settlement volume, mostly through their cross-border B2B pilot. That’s real money, not speculative volume.

But here’s where it gets interesting — and where my own experience as a DeFi Summer survivor kicks in. I remember the 2020 yield farming mania, where everyone thought 'code is law' would replace banks. I lost $15,000 AUD in an unaudited smart contract exploit, and that failure taught me to look for the cracks. Souza’s interview reveals several.
The most critical crack is bank adoption. Souza admitted that banks still have ‘legitimate concerns’ about integrating stablecoins: anti-fraud mechanisms, source of funds checks, and compliance with Know Your Business (KYB) standards. These are not trivial. In my own work building an education platform, I’ve seen dozens of fintech projects fail because they underestimated the complexity of regulatory compliance. The real bottleneck in stablecoin adoption is not blockchain scalability — it is the willingness of traditional banks to trust a system that was originally designed to be trustless.
Visa’s solution is the Visa Connector, which is essentially an application-layer API that allows banks to initiate stablecoin transactions without needing to deeply understand the underlying blockchain. This is clever, but it’s also a admission: decentralization is a feature for crypto natives, but a bug for institutions. Visa is building a centralized bridge between two worlds, which works for now, but creates a dependency that undermines the core promise of permissionless finance.
Now for the contrarian angle. If stablecoins are so limited — only useful for cross-border B2B and dollar savings — why is the market exploding? The answer, I believe, is inflation. The real driver of crypto payments in developing countries isn’t blockchain ideology; it’s local currency inflation forcing people to find survival alternatives. Souza hinted at this when she noted that Brazil is the ninth-largest crypto market by adoption, but the piece didn’t explicitly connect the dots. My research into Latin American payment patterns shows that stablecoins are becoming a de facto store of value in countries like Argentina, where annual inflation exceeds 100%. This is not about replacing PIX. This is about people protecting their purchasing power by any means necessary.
That’s a different narrative — one that doesn’t require fancy L2 scaling or flashy DeFi yields. It’s a survival narrative. And it’s far more robust than the speculative mania we see in bull markets.

Finally, the takeaway. Souza predicted that ‘the real convergence between crypto and traditional payments will happen in five years.’ That’s a long time in crypto — approximately 50 narrative cycles. But for a company like Visa, which has been building payment rails for over 60 years, five years is nothing. They are playing a different game.
The message for founders, investors, and users is simple: Don’t confuse the FOMO with the fundamentals. Stablecoins are not going to replace your bank tomorrow, nor are they the enemy of national payment systems. They are a tool for specific, high-value problems: cross-border settlement, dollar access in inflationary environments, and — possibly, in the future — machine-to-machine payments by AI agents. Visa is betting on that last one, and they have the resources to wait.
We didn’t need another landing page promising 'decentralized everything.' What we needed was a sober assessment of where stablecoins actually fit. Souza gave us that. Now it’s up to us to pay attention.
Truth in blockchain isn’t found in code alone. It’s found in the conversations that remind us of our limits.
