Rep. Carlos Jordy (PL-RJ) has called for the creation of a joint parliamentary commission of inquiry to investigate Banco Master.

The push for a probe comes amid allegations of a high-level effort to protect the bank from scrutiny while the Brazilian Congress fast-tracks other legislation. This tension highlights a potential conflict between legislative priorities and the pursuit of accountability for financial crimes.

During an interview on April 19, 2026 [1], Jordy described the Banco Master situation as the "caso mais tenebroso de corrupção" — the most sinister case of corruption [1]. He said there is a significant "blindagem," or shielding, surrounding the case that prevents a full investigation.

This effort to establish a commission follows a legal shift in the Brazilian judiciary. On April 26, 2026 [2], the Supreme Federal Court issued a decision that overturned an injunction regarding a different commission, the CPMI do INSS, which has since reopened discussions about the viability of a probe into Banco Master [2].

However, internal political dynamics may be hindering the process. Reports from April 9, 2026 [3], suggest that government allies believe the urgency to vote on the Dosimetria bill is linked to an agreement to avoid installing the Banco Master commission [3].

Jordy continues to advocate for the rapid approval of the Dosimetria bill while simultaneously demanding that the Banco Master investigation proceed. He said the public deserves transparency regarding the financial irregularities involved in the case.

“"Caso mais tenebroso de corrupção"”

The clash between the push for the Dosimetria bill and the demand for a Banco Master probe suggests a political trade-off. If the allegations of a 'shielding' agreement are true, it indicates that the legislative timeline for judicial dosing reforms may be being used as leverage to protect financial interests from parliamentary oversight.
