Stablecoin Economics: How Dollar Dominance, Cross-Border Payments, and Monetary Substitution Are Reshaping Global Finance

The Real Engine Behind Stablecoins
I don’t care about blockchain utopianism. What drives $2.2T in stablecoin market cap? It’s not decentralization—it’s interest rate arbitrage. Issuers earn 4% on US Treasuries while paying holders zero. That’s not innovation; it’s narrow banking with a crypto veneer.
Why Dollars Win—Again
Stablecoins aren’t replacing the dollar—they’re its most efficient vector. When Turkey or Argentina sees inflation hit 80%, people don’t buy Bitcoin. They buy USDT—because cash is bulky, banks are slow, and Treasuries are liquid. The asset isn’t the chain—it’s the Fed.
The Illusion of Competition
People say ‘digital euro’ will challenge this. Wrong. Eurochain adoption is a policy statement—not an economic force. China’s WeChat Pay works because its infrastructure serves real trade—not because it’s decentralized.
The Underground Edge
The real demand? Gray markets and sanctions evasion. Russia trades oil for USDT; Iran bypasses SWIFT. Not because it’s anonymous—it’s because the existing system is brittle.
The Vulnerability Nobody Talks About
USDC de-pegged in 2023 when SVB collapsed—not due to code failure, but panic over reserve opacity. Tether holds BTC as collateral? That’s not innovation; it’s wildcat banking with a whitepaper.
What Comes Next?
If rates drop below 1%, this whole architecture evaporates overnight. Stablecoins thrive on spread—and vanish when the spread dies.
I’ve seen this before—in ’08, banks thought leverage was smart too.

Nung una kong narinig ang stablecoin… akala ko ‘digital currency’ pala yung bagong pera na ginagamit ng mga tito sa Quiapo! 😅 Hindi Bitcoin—yung USDT lang ang nakakapalabas sa panahon ng inflation. Ang Fed? Puro galing na ‘cash’ na may whitepaper. Sana all maganda ang kalagayan natin… pero sana may WiFi pa! 🤭 #CryptoWithHeart

달러가 스테이블코인의 진짜 뒰? 터키나 아르헨티나 사람들이 비트코인 대신 USDT를 사는 이유? 현금은 무겁고 은행은 느리지만, 연방채는 촉촉하니까요. 블록체인은 꿈이고, 실질은 ‘달러의 그림자’입니다. 우린이 유로를 만든다구요? 그건 정책 발표지~. 2023년 USDC가 빠졌을 때… 진짜 원인은 코드 오류가 아니라 “현금 없는 공포”였죠. 다음엔 뭐 나올까요? 달러가 죽으면… 우리도 백화서적을 들고 있어야 할 것 같네요. (그림: 달러가 머리에 왕 crowns 쓰고 있는 일러스) 오늘 당신이 사는 건 무엇인가요?

الدولار ما يُستبدل… هو اللي بياكلهم! عندما تهتزّ التضخم في تركيا، الناس ما يشتريوا البيتكوين، بل يشتريوا USDT لأن النقود الثقيلة والبنوك بطيئة، والخزائن سائلة! حتى السويفت صار كأنه مكتب قديم وبيت الكريبتو ورقية زرقاء داكنة. لو حسبتوا إن اليورو الرقمي سيحل هذا؟ لا يا جمهوراً… هو نفس القصة من سنة 2008! شوفوا الـUSDC نزل من الرف؟ نعم، لكن المحفظة كانت فارغة قبل ما تفتح الحقيقة.
إيهي؟ خلك تحطّب؟

Wer glaubt noch an einen digitalen Euro? Die Deutschen kaufen lieber USDT — weil Bier teuer ist und die EZB nur mit Treasuries zahlt. ZK-Rollups sind nicht Innovation, sondern der einzige Ausweg aus der Inflationsschraube. Wenn die Fed mal wieder schlafen geht, bleibt die Liquidität im Kühlschrank — und niemand kauft Bitcoin… nur weil das Handy kaputt ist. Wer will denn noch SWIFT? Was hat der Bierkasten mit dem Whitepaper? 😅 #DeFiMitBier
