Cross-border B2B payments in 2027: five trends to budget for
Five regulatory and infrastructure trends shape cross-border B2B payments in 2027. This article turns them into what a Latin American CFO has to budget: cost, timing, compliance and treasury.
A CFO preparing the 2027 budget usually hears about regulatory changes one at a time, each with its own alert and its own adviser. The result is a list of rules and no decisions. What is needed is the opposite: what changes in cost, timing, compliance and treasury, and which budget line to open before January.
Soulbit Academy has already published the detail of each rule. This article does not repeat them: it arranges them the way a budget sheet would. For the quarter's calendar, start with our Q4 2026 regulatory calendar for LATAM and come back here to decide what to do with each date.
Five trends, one set of budget questions
The five trends rest on verifiable official sources: the GENIUS Act on payment stablecoins, the OECD's CARF, Brazil's DeCripto, Brazil's split payment and the central bank instant payment systems. All affect the 2027 budget, though in different states: two already operate (DeCripto and instant payments), two have their milestone in 2027 (the GENIUS Act and the first CARF exchange) and one has no official date (split payment). That is why now is the time to turn them into budget lines.
For each one, ask the same thing: does it change cost, timing, compliance workload or working capital? The table summarises the answer and the sections below develop it.
| Trend | What changes for the CFO | Status as of October 2026 |
|---|---|---|
| GENIUS Act (US) | Issuer counterparty risk and the timing of decisions on which stablecoin to hold | OCC final rule published October 21, 2026; law applies by January 18, 2027 at the latest |
| CARF (OECD) | Compliance and data: your provider reports, you reconcile | Data collection in 2026; first exchange between countries in 2027 |
| DeCripto (Brazil) | Compliance: its own obligation if you deal with Brazil outside a local provider | Aggregated reporting from January 1, 2026; the rest from July 1, 2026 |
| Split payment (Brazil) | Treasury: collections arrive net of tax | No verified official date; press cites optional 2027 and mandatory 2028 |
| Instant payments (Pix, SPEI, Bre-B) | Timing and cost of the local last mile, not the international leg | Operating; Bre-B fully live since October 6, 2025 |
Why would a US or Brazilian rule affect my company if it operates elsewhere?
Because the payment chain crosses borders even when the company does not. A client in Miami or a supplier in São Paulo passes its obligation to its counterparty, as more data, more verification or less liquidity on collection day.
Trend 1: the GENIUS Act, a counterparty risk budget
The GENIUS Act, signed on July 18, 2025 and published as S. 1582 on Congress.gov, creates the US federal framework for payment stablecoins. It requires 1-to-1 reserves, monthly publication of their composition and bans the issuer from paying interest to holders. The detail is in our analysis of how its rulemaking is advancing.
What is new since we published it: the OCC adopted its final rule on October 21, 2026, according to its bulletin 2026-50. It covers the requirements the agency had to set, except the anti-money laundering and sanctions part, which goes through a separate process with the Treasury. As of October 30, 2026 we have not verified final rules from the other agencies, so the law's second trigger remains unclear.
What does this mean for the budget? The law does not bind the company that collects or holds USDC or USDT: it binds the issuers. The effect on your accounts is indirect and shows up in three places:
- Counterparty risk. Until each issuer is licensed, the soundness of the instrument depends on its progress. It is not a cost but a decision: what share of operating balances sits in each stablecoin.
- Decision timing. With January 18, 2027 as the outer date, close the review of which stablecoin to hold in the fourth quarter.
- Due diligence. Allow hours to review, each month, the reserves the issuer publishes.
What should my treasury ask its US counterparty before January? Three things that can be checked today: under which licensing route the issuer operates, whether it has filed a formal application, and how it publishes its reserves.
Trends 2 and 3: CARF and DeCripto, a compliance budget
CARF is the OECD standard for automatic exchange of tax information on crypto-assets. Implementation depends on each jurisdiction: in first-wave countries that have enacted the framework, data collection may begin in 2026 and first exchanges are expected in 2027, according to the OECD monitoring report. Other jurisdictions have later schedules. Our article on what CARF means for companies covers the full framework.
For the CFO the change is one of visibility. In countries that implement CARF, tax authorities may exchange data reported by crypto-asset service providers alongside what the company declares. The provider reports identification, type of crypto-asset, fair value and number of transactions, and the data crosses borders every year. The reporting does not distinguish USDC from other crypto-assets: an operating stablecoin balance is covered the same way.
DeCripto adds an obligation of its own in Brazil. Normative Instruction RFB 2,291/2025 creates the declaration, aligned with CARF, and the Receita Federal describes it on its official page. Aggregated reporting applies from January 1, 2026 and the rest from July 1, 2026. An entity resident in Brazil that operates without a Brazilian provider files on its own once it exceeds the monthly threshold of 35,000 reais. We explain it in what DeCripto is.
How much does CARF and DeCripto compliance cost?
There is no official figure and we do not invent one. The cost is mostly time and process, not fees. It breaks down into three tasks you can estimate with your own data:
- Current identification data, including the beneficial-owner information your provider asks for.
- Annual reconciliation of what your provider reports against your books.
- A review of the Brazilian obligation, if you deal with Brazil outside a local provider.
Trend 4: split payment in Brazil, a working capital budget
Split payment is the mechanism by which Complementary Law 214/2025 provides for consumption tax to be separated at the settlement of each payment: the seller receives the net amount and the tax authority its share. The law regulates it in articles 31 to 35, and its text is on the Planalto website. Our full analysis is in split payment in Brazil and invoice collection.
Its effect is on treasury, not on the total tax burden. The tax does not disappear: it is paid at collection rather than weeks later. An illustrative case, which is an assumption and not market data: a 120,000 BRL invoice with 20,000 BRL of tax arrives as 100,000 BRL of cash. Before, those 20,000 BRL funded a few weeks of working capital.
The calendar is the least clear part. As of October 2026 we found no official act fixing the date. Press cites an optional start in 2027 and mandatory use between companies in 2028, and in August 2026 a postponement without a new date was reported. The Receita Federal guide to the reform places the start of actual CBS collection in 2027.
So budget with scenarios. If your company collects from Brazilian clients, calculate how much cash would stop arriving on collection day in each case and which credit line or cash buffer would cover it. If you do not collect from Brazil, the trend reaches you only through counterparties.
Trend 5: instant payments, a last-mile timing budget
Pix, SPEI and Bre-B are central bank instant payment systems that move local currency inside one country, around the clock. Our analysis of Pix, SPEI and Bre-B for companies compares them. Bre-B, in Colombia, has been fully operational since October 6, 2025.
Their limit is structural. The Banco Central do Brasil states in its Pix management report that Pix only allows domestic transactions. The border is crossed outside the system. These rails improve the timing and cost of the local leg, not the international one.
For the budget the effect is lighter but real. Collecting and paying in local currency with a key or QR reduces dependence on traditional hours and eases reconciliation. The line to review is reconciliation time and local fees, which each financial institution sets, not the system.
| Trend | Budget line affected | Decision worth taking before January 2027 |
|---|---|---|
| GENIUS Act | Counterparty risk and due diligence | Set what share of operating balances sits in USDC and USDT, and review each issuer's licensing status |
| CARF | Compliance and data | Confirm with each crypto-asset provider whether it is covered and update identification data |
| DeCripto | Compliance in Brazil | Ask your tax adviser for written confirmation of whether you cross the monthly threshold |
| Split payment | Working capital | Model the cash that would stop arriving on collection day in three date scenarios |
| Instant payments | Local timing and reconciliation | Measure how long the collection-to-reconciliation cycle takes today and set a target for the last quarter |
How to order these decisions in one budget
For the last quarter of 2026, the recommended order is: first, counterparties and stablecoins, which have the nearest date; second, data for CARF and DeCripto; third, split payment scenarios; fourth, measuring the local collection cycle.
With the five trends on one sheet a pattern appears: two are about compliance, one about risk, one about cash and one about timing. None demands a large technology investment. All demand dates, owners and data.
Leave a column for what is not known: the remaining final GENIUS rules, the split payment calendar, the DeCripto threshold for your case and each country's CARF wave. Noting who will confirm each and when is worth more than an assumed figure.
What Soulbit delivers today on this framework, and what it does not
Soulbit is a custodial platform: institutional custody protects the client's assets. Its V1 works with USDC and USDT, fiat in USD, EUR and GBP, and a local bank rail in Colombia only. It includes KYB, recurring and batch payroll, payment links, collection QR codes, conversion by quote on request through an OTC exchange, and AML and KYT monitoring.
Soulbit is not a stablecoin issuer and depends on the USDC and USDT issuers progressing with their licensing. The GENIUS Act regulates issuers of payment stablecoins; if your company only uses them to pay, confirm with your adviser whether any obligation reaches you. KYB and AML and KYT monitoring support the identification processes that CARF and local rules describe, but do not replace your tax advice. Batch payroll eases reconciliation by paying several recipients in one operation.
Soulbit does not promise yield, APY or a proprietary token. Check official channels for card and mobile app availability. There is also no local bank rail outside Colombia, so a company needing to settle in Brazilian or Mexican local currency must solve that last mile on its own.
Frequently asked questions
Which five trends affect cross-border B2B payments in 2027?
The US GENIUS Act on payment stablecoins, the first CARF exchanges in jurisdictions that implement it, Brazil's DeCripto declaration, Brazil's split payment, and the growth of domestic instant payment rails such as Pix, SPEI and Bre-B. Each one touches a different budget line: counterparty risk, compliance, working capital or reconciliation.
When does the GENIUS Act apply, for budgeting purposes?
The law applies on the earlier of two dates: January 18, 2027, or 120 days after the main regulators publish final rules. As of October 30, 2026 the OCC has published its final rule, but other agencies are still pending. For budgeting, treat January 18, 2027 as the outer limit.
Does a small company that only pays suppliers in stablecoins need to care about CARF?
Indirectly, yes. Where CARF is implemented, crypto-asset service providers report user data; timing depends on the jurisdiction. For the company the cost is administrative: keeping identification data current and reconciling what the provider reports against its own books.
When does mandatory split payment start in Brazil?
No verified official date exists. As of October 2026 specialist press cites an optional start in 2027 and mandatory use between companies in 2028, and the schedule has moved several times. Budgeting with scenarios rather than a single date is the prudent option.
Do instant payment systems like Pix or Bre-B replace cross-border payments?
No. They are domestic central bank systems that settle in local currency inside one country. The border is crossed outside the system. They improve the cost and timing of the local last mile, not of the international leg.
