The International Monetary System Is Being Rebuilt. Here Is Every Brick.
Central Bank Digital Currencies, tokenized deposits, stablecoin regulation, cross-border settlement networks — these are not future scenarios. They are active programs at every major institution in the global financial system. This is the map of what is actually happening, who is building it, what technology underlies it, and what it means for every person who uses money.
GMIIE VIEW Arguably the most significant structural transformation since Bretton Woods — what looks from the outside like a fragmented collection of central bank digital currency experiments is, viewed from inside participating institutions, a coordinated reconstruction of the rails on which money moves. DATA GMIIE tracks activity across 134 jurisdictions as of Q2 2026.
The story has three layers. The first is retail: what currency ordinary people will use, how they'll hold it, and who controls their access to it. The second is wholesale: how banks settle with each other, how sovereign obligations are discharged, and who has authority over the clearing layer. The third is geopolitical: which nations' infrastructure becomes the global standard, whose currency maintains reserve status, and how the dollar's six-decade dominance adjusts to a multipolar monetary world.
All three layers are active simultaneously. The decisions being made in BIS working groups, Fed research divisions, and Polygon validator networks right now will determine the financial architecture of the next fifty years. This brief covers all of it — with educational depth, institutional accuracy, and HD voice narration if you'd prefer to listen.
FACT Public trackers such as the Atlantic Council CBDC Tracker typically count 3–4 retail CBDCs as fully live (e.g., Bahamas, Jamaica, Nigeria, and sometimes Zimbabwe).
GMIIE VIEW We classify as “live” any CBDC or CBDC-like settlement system in production with real money and real counterparties — including selected wholesale platforms and multi-CBDC bridges (e.g., mBridge). That yields 11 live systems in our registry versus the narrower retail-only count above.

A stablecoin is a digital token designed to maintain a fixed value relative to a reference asset — most commonly the US dollar. Unlike Bitcoin (which fluctuates) or a CBDC (which is government-issued), a stablecoin is private money, issued by a company, backed by reserves, and running on a public blockchain. The ~$175 billion stablecoin market (approx., May 2026) is, in practice, one of the largest private payments rails globally.
The economics are straightforward: you deposit $1, you receive 1 stablecoin, you can use that stablecoin to transact on any blockchain that supports it, and you can redeem 1 stablecoin for $1. The complexity is in the reserve: what backs the dollar claim? Who audits it? Who can freeze your tokens? Who is liable if the issuer fails?
GMIIE VIEW The GENIUS Act provides the first comprehensive federal stablecoin framework in US discourse — reserve rules, attestations, and licensing — though implementation details and overlapping securities/commodities regimes remain open questions. Offshore structures face market-access friction; onshore, fully reserved issuers and bank-chartered products gain structural advantage.
| Stablecoin | Issuer | Market Cap (approx., May 2026) | Backing | Chain | Regulatory Status | GENIUS Act Impact |
|---|---|---|---|---|---|---|
| USDT (Tether) | Tether Ltd (BVI) | ~$118B | T-bills, reserves, "other" | Tron (~50% of supply), Ethereum (~35%), others | Gray Area | Excluded — offshore structure |
| USDC (Circle) | Circle (US, Delaware) | ~$43B | T-bills + Fed bank accounts | Ethereum, Solana, Base | Compliant | Winner — US structure aligned |
| JPM Coin | JPMorgan Chase | $1B+ daily volume | JPM bank deposits (FDIC) | Onyx (private EVM) | Bank-issued | Winner — bank-chartered |
| EURCV | Soci — t — G — n — rale | — 100M+ | Euro cash reserves | Ethereum, Stellar | MiCA Compliant | EU jurisdiction — unaffected |
| PYUSD | PayPal / Paxos | $500M | T-bills + cash | Ethereum, Solana | Paxos Trust | Compliant — US structure |
| FDUSD | First Digital (HK) | $2B | HK dollar cash | BNB Chain, Ethereum | SFC Hong Kong | HK jurisdiction — watching |
| DAI / USDS | MakerDAO / Sky | $5B | Crypto collateral (overcollateralized) | Ethereum | DeFi Native | DeFi front-ends affected |
FACT XRPL offers fast finality, low fees, and built-in DEX features suited to RTGS-style settlement experiments. GMIIE VIEW One of the most mature public-chain RTGS-style ledgers — not a claim against TARGET2 or Fedwire.
FACT Bhutan and Palau have run limited-scope pilots/partnerships involving XRPL infrastructure. Frame as pilots and constrained deployments, not full national stack replacements.
FACT Ripple ODL corridors (e.g., Philippines, Singapore, Mexico) remain active post-SEC settlement. GMIIE VIEW Reported volume growth has been significant quarter-over-quarter; avoid pinning a single percentage without a dated source.
GMIIE VIEW In many inflation-hit emerging markets, TRC-20 USDT on Tron functions as a de facto dollar rail for remittances and everyday transactions — with roughly half of total USDT supply hosted on Tron as of early 2026 (public issuer/chain analytics vary by snapshot).
Low per-transaction fees and ~3-second settlement drive adoption where correspondent banking is slow or costly. Nigeria, Turkey, Argentina, Venezuela, and similar markets show heavy informal USDT use — always verify jurisdiction-specific legal status.
GENIUS Act friction for offshore issuers affects US market access; Tron's primary user base remains outside US-regulated on-ramps.
