Evidence that changes how institutions price Brazil.

Nostrum Public Affairs is a public affairs firm working on two questions: how the Brazilian financial system prices what is built, and how Brazilian trade meets European regulation. We build and commission the evidence, and we put it in front of the credit committees, regulators and institutions that act on it.

Evidence that holds when it is checked.

Credit committees, investment mandates and Commission directorates run on the same thing: proof that holds up under scrutiny. For Brazilian real estate, and for Brazil–Europe trade, most of it does not yet exist. Our work is to get it produced, verified by parties we do not control, and delivered where decisions are made.

Verified, not asserted

Whether we build a methodology, as with PROVA Brasil, or commission a study from independent institutions, the findings are audited by parties with their own name to protect and published as found.

Standards, not dependencies

Programmes are designed to leave a replicable methodology or a published record behind. A client should not need us to keep using what was built.

Two practices

Sustainable finance and real estate

Changing how credit committees read a certified building

Brazilian real estate credit prices the borrower and ignores the building. Certified assets appear to perform differently on the variables a credit committee actually uses, DSCR, NOI, recovery under stress and valuation, but the audited evidence to price that difference has never been produced. We produce it, with the banks and developers who will use it, under Brazil’s own prudential framework. European interoperability follows from that base; it is not the starting point.

  • Audited, asset-level evidence on certified buildings as credit: DSCR, NOI, recovery under stress, valuation
  • Integration into risk models under CMN 4.557 (expected loss) and CMN 4.945 (climate responsibility), and into GRSAC reporting
  • Green CRIs and structured instruments priced on that evidence
  • Interoperability with the Taxonomia Sustentável Brasileira and the EU Taxonomy, for markets without EPCs
  • SFDR Article 9 and Global Gateway positioning for European capital, once the Brazilian evidence base exists
  • Replication of the methodology across Latin America

EU–Brazil trade and regulatory policy

Reading three European instruments that were not written to read each other

The EU–Mercosur interim trade agreement has been provisionally applied since May 2026. Its definitive entry into force still requires the consent of the European Parliament, which will vote only after the Court of Justice has delivered the opinion Parliament requested in January 2026. CBAM entered its definitive phase in January 2026 and the EUDR applies to medium and large operators from 30 December 2026, all in the same window.

We read Brussels for Brazilian agriculture: what the agreement and the two regulations will require of an exporter and its European buyer, when, which parts are still moving through reviews and votes, and how the politics around each is likely to shift the answer.

Programme

PROVA Brasil

A GBC Brasil programme, with Nostrum as execution lead and IDB Invest as anchor funder. Its purpose is to move Brazilian real estate credit from a model where only the borrower’s risk counts to one where the quality of what is built also counts. Phase 1, the Casa Toolkit, mapped the certified stock. Phase 2, PROVA Brasil, is being launched: a Steering Committee constituted in September 2026 selects a cohort of ten to fifteen developer projects, followed over eighteen months to produce the audited, asset-level evidence a credit committee can act on.

What changes for a Brazilian lender

Today a certified building and a conventional one enter the same risk model and leave with the same spread, because there is no third-party verified, as-operated performance variable to separate them. PROVA produces that variable. The Casa Toolkit estimated an association, not causality; Phase 2 will test it on live projects with the banks and developers in the room.

What follows

A Brazilian evidence base in credit language is also what the EU Taxonomy lacks for markets without Energy Performance Certificates. Once it exists, European capital under SFDR Article 9 and Global Gateway can read Brazilian assets. That is a consequence of the Brazilian work. The purpose is narrower: a market adopts sustainability when it pays, and it pays only once it is priced. The methodology is built for replication across Latin America and will have its own home as a standard.
