History of cross-border stablecoin payments, 2014 to 2026

The history of cross-border stablecoin payments is a three-stage story. From 2014 to 2019, dollar tokens served crypto traders. From 2020, Pix (Brazil's instant payment system) and other local rails gave them a last mile into bank accounts. From 2022, laws in Brazil, the EU, the US and Hong Kong made them regulated payment instruments.

The token came first, the local payout rail second, and the rulebook last. It is still arriving. This post gives each date and its source and marks what is not yet in force. The asset itself is in what a stablecoin is.

What are the key dates, in one table?

Eighteen dates carry most of the story. Each norm links to its official source.

Key dates for cross-border stablecoin payments, 2014 to 2028, checked November 1, 2026.

2014 to 2019: dollar tokens for traders

Tether says it launched in 2014, on its own site, as a platform for using fiat currency on blockchains. USDC followed in 2018, issued by Circle, which publishes reserve reports. Both were dollar tokens anyone with a wallet could send across a border without a bank in the middle. For a business that was not enough: dollars in meant one crypto exchange, local currency out another.

The two ends of the payment did not yet exist as a product. The USDC explainer covers the issuer side.

2020 to 2022: local rails give the token a last mile

Business use has no launch date. The cleanest marker of a fast last mile is Pix, which the Central Bank of Brazil (BCB) launched on November 16, 2020. Pix runs all day, every day, between any two bank accounts in Brazil. A dollar token that can land in a Pix key within minutes does something a correspondent chain cannot: it pays a Brazilian supplier on a Sunday.

Mexico's SPEI (Mexico's interbank transfer system, run by Banxico) works the same way; we date no SPEI event here. That is a stablecoin corridor: fiat in on a local rail, a stablecoin in the middle, fiat out on another. In the same stage Brazil passed Law 14.478 on December 21, 2022, the first dated step toward treating the middle of the payment as a regulated business.

On Lumx, this stage looks like the USDC to BRL corridor. The BRL account is provisioned right after the customer is approved, and the docs list Pix as instant. An autoconversion rule turns each Pix deposit into USDC or USDT in the customer's wallet, and a payout is an off-ramp to a registered destination. The wallet holds balances between steps, so a client can fund once and pay many times. Stellar carries only the BRL to USDC on-ramp, so it is not a payout path. Webhooks report each status (docs read November 1, 2026: rail coverage).

2022 to 2026: statutes arrive, jurisdiction by jurisdiction

Regulation did not arrive as one global rule. In May 2022 TerraUSD lost its dollar peg, which made regulators ask who stands behind a stablecoin. In March 2023 USDC traded below one dollar for a short time after Circle disclosed that part of its reserves sat at Silicon Valley Bank, which showed that where reserves are held is a risk too. Rules then arrived region by region, each with a different object. The EU regulated the asset and the provider: MiCA (Regulation (EU) 2023/1114) took effect in stages, on June 29, 2023, June 30, 2024 and December 30, 2024. The US regulated the issuer: the GENIUS Act, Public Law 119-27, signed on July 18, 2025, sets who may issue a payment stablecoin there.

Hong Kong regulated issuance too: since August 1, 2025, issuing a fiat-referenced stablecoin there needs a licence from the Hong Kong Monetary Authority (HKMA). Mainland China went the other way: the People's Bank of China's notice Yinfa [2026] No. 42 of February 6, 2026 prohibits foreign crypto services to people in the mainland. This post does not date the Singapore (MAS) or UK regimes, because we did not read their primary texts for it. The UK, Singapore and Hong Kong comparison covers them.

Brazil regulated the provider, which is the party a payments company is. The BCB published Resolutions 519, 520 and 521 on November 10, 2025, and Resolution 520/2025 took effect on February 2, 2026, with 270 days for companies already operating to file. The detail is in stablecoin regulation in Brazil in 2026, and Mexico's CNBV (Mexico's banking and securities regulator) framework is in stablecoin regulation in Mexico.

In Brazil, Lumx Sociedade Prestadora de Serviços de Ativos Virtuais Ltda (Lumx SPSAV Ltda) applied for the SPSAV authorization and operates under the transition regime of Article 88 of Resolution 520/2025. We do not describe ourselves as authorized or licensed by the BCB. In the United States, Lumx US OP LLC, in Wyoming, is registered with FinCEN as an MSB (money services business, the FinCEN registration category). Lumx is custodial: it holds the stablecoins, runs KYB (know your business) and KYC (know your customer), and operates the payout rails, so a client does not need to run a crypto operation of its own.

Bre-B and the cap on Colombia's last mile

Bre-B (Colombia's instant payment system, as instant as Pix, launched in 2025) is the newest piece of the LatAm last mile. It has a rule the other rails lack: the Banco de la República caps each Bre-B transaction at 1,000 UVB, which is COP 12,110,000 for 2026, under Circular Reglamentaria Externa DSP-465, Asunto 18, numeral 3.2.

For a payer, the practical effect is a rail choice. A COP 15 million invoice sent to a Bre-B key is refused at the cap, not split. ACH Colombia has no per-payment limit and is the rail for the larger invoice. PSE (Colombia's online bank-transfer network) only collects.

At Lumx, COP collection runs through the Bre-B key of the COP account or through PSE, and payout runs through Bre-B or ACH Colombia, chosen when the destination is registered. A Bre-B destination above the cap is declined, so the client sets up an ACH Colombia destination for large invoices. The COP account is available to any client; it is named only when the client is Colombian. See the payment coverage page for the current list and the USDC to COP page for the pair.

Dates and open questions ahead

Two dated items are ahead. The GENIUS Act takes effect on the earlier of 18 months after enactment, January 18, 2027, or 120 days after final implementing regulations. Section 3(b) then makes it unlawful, from July 18, 2028, for a digital asset service provider to offer a payment stablecoin to a person in the US unless a permitted issuer issued it, subject to exceptions for qualifying foreign issuers.

Brazil's date just passed: the filing window for incumbents closed on October 30, 2026, and providers that filed operate under the transition regime of Article 88 of Resolution 520/2025 until the BCB decides.

What the dates mean when you choose a rail

<!-- OPERATOR PARAGRAPH --> I recommend reading this timeline as three questions to ask for every corridor, not as a story of steady progress. Who issues the token, and under which regime? Which local rail pays out at the other end, and what caps it? Which authorization does the provider in the middle hold, and since when? I would not skip any, because each moved on its own schedule, and a corridor can be solid on two and weak on the third.

The same reading explains why the old route still has a place: a correspondent-banking payment gives one regulated counterparty chain and slow settlement, and a stablecoin route gives fast settlement and three regimes to check. FX swaps versus stablecoins takes the treasury view, and Latin America cross-border payments compares the routes by corridor.

When a stablecoin is the wrong tool for a corridor

A supplier in mainland China cannot be paid in stablecoin: the February 6, 2026 notice makes USD by correspondent bank the route. A Hong Kong company can still receive USDT, and that is a separate corridor from the mainland one.

It is also wrong when both ends are in one country and a local rail already settles at once, or when a payment exceeds a rail cap and no second rail is set up, as with a Bre-B invoice above 1,000 UVB.

At Lumx, mainland China is paid in USD over SWIFT, and a Hong Kong company in USDT through a transfer to an external wallet. Lumx serves Hong Kong clients by reverse solicitation and holds no HKMA licence. We do not offer CNY settlement.

What this history looks like in a Lumx payment today

Lumx is stablecoin payments infrastructure for businesses that move money between Latin America and the rest of the world: one API to collect, hold, convert, and pay out in BRL, MXN, COP, USD, EUR, and GBP or in USDC and USDT, over local rails such as PIX, SPEI, PSE, Bre-B, ACH, FEDWIRE, SEPA, and Faster Payments, with SWIFT and on-behalf-of payments and collections (POBO and COBO) in USD, EUR, and GBP, plus named virtual accounts, custodial wallets, and KYB/KYC built in.

Each stage is a layer in one payment. A client collecting from Brazilian buyers receives a Pix deposit in a BRL account, converted to USDC in a custodial wallet. From the same wallet it pays a supplier in Colombia over Bre-B or ACH Colombia, and one in Hong Kong in USDT. Every transfer carries a webhook, and every SWIFT payout a UETR and an MT103 confirmation. The global payments product page lists rails and currencies; the coverage page lists them by country.

Methodology and sources

Not served as text that day: the BCB's Pix page (it needs JavaScript) and BCB Resolutions 519, 520 and 521, which are linked to the BCB's official pages without having been read there, Law 14.478 on planalto.gov.br and MiCA on EUR-Lex (a bot challenge), linked the same way, the Banco de la República's Bre-B pages (captcha, so only the year of the launch is given), the TerraUSD collapse of May 2022, Circle's statement of March 2023 on its reserves (the blog page did not serve the article), and the People's Bank of China notice, cited without a link. The MiCA stage dates link the European Commission page for the Regulation. The Bre-B cap comes from the Banco de la República texts read for the Lumx Bre-B posts.
