Since September 1, 2026, part of version 8.5 of the DICT Operational Manual has already been in force: the deadline for contesting a fraudulent refund transaction increased from 30 to 80 days. Another part of the same update, however, only takes effect on October 26, 2026: the addition of “graph depth” information (TransactionDepth) to infraction reports and to the Funds Recovery analysis stage. The two dates were separated by BCB Normative Instruction No. 767, which changed the schedule originally published in BCB Normative Instruction No. 766.
What is already in force and what is not yet in force
| Date | What changes | Status | Where it appears in the manual |
|---|---|---|---|
| Sep. 1, 2026 | Deadline for contesting a fraudulent refund transaction increases from 30 to 80 days | Already in force | Sections 20.1.1, 20.1.9 and 20.2 |
| Oct. 26, 2026 | Infraction reports begin to include the tracking-graph layer of the transaction under analysis through the TransactionDepth attribute | Not yet in force | Sections 10.1 and 20.1.5 |
| Oct. 26, 2026 | Revocation of BCB Normative Instruction No. 752/2026 | Has not yet occurred | Article 3 of BCB Normative Instruction No. 766, as amended by No. 767 |
The breakdown above is the safest way to read the consolidated rule. BCB Normative Instruction No. 766 issued version 8.5 of the manual; three days later, BCB Normative Instruction No. 767 changed the effective dates for part of the amendments.
What DICT is and why a change to it affects Pix
The Transaction Account Identifier Directory (DICT, in the Portuguese acronym) is a database managed and operated by the Central Bank of Brazil that stores information linked to Pix keys and transaction accounts. It also participates in security and funds-recovery flows. The Central Bank itself describes DICT as the component that makes it possible to retrieve account details from a Pix key and helps mitigate fraud risk. The institutional description is available on the DICT page.
The September and October 2026 changes do not mean a general change to Pix-key registration or to the way a Pix payment is made. They focus on the Funds Recovery flow and on infraction reports used in cases of suspected fraud.
What changed on September 1: more time to contest a refund
In version 8.4 of the DICT Operational Manual, the Funds Recovery initiation rule distinguished between two deadlines. An original pacs.008 transaction could be contested within 80 days, while a pacs.004 refund transaction could be contested within 30 days. Section 20.1.9 likewise stated that a fraudulent refund transaction had to be contested within 30 days after the refund.
Version 8.5, issued by BCB Normative Instruction No. 766, extended that second deadline to 80 days. The revision history identifies the change in Sections 20.1.1, 20.1.9 and 20.2, effective September 1, 2026. The previous wording can be checked in the DICT Operational Manual.
What kind of situation the rule addresses
This contest is not a generic way to “undo a Pix.” The manual deals with a refund transaction that is itself challenged on suspicion of fraud. In version 8.4, the Central Bank gives as examples a refund of the root transaction in a Funds Recovery case opened with the purpose of defrauding the recipient, and a proactive refund made under coercion.
In practical terms, imagine a recipient who legitimately received a Pix payment but later had a refund processed as part of a fraudulent case. The recipient’s payment service provider can review the complaint and, when appropriate, open a new Funds Recovery process with the refund transaction as the root. Since September 1, the prescribed window for that contest is up to 80 days, rather than 30.
What the 80 days do not mean
- They do not create a right to cancel any Pix payment simply because someone changed their mind.
- They do not turn an ordinary commercial dispute into fraud. The Central Bank states that the MED does not apply, for example, to simple disputes over a product or service when there is no fraud.
- They do not guarantee full recovery of the money. The outcome depends on the case review and on the availability of funds in the accounts involved.
- They do not replace the recommendation to act quickly. For fraud victims, the Central Bank advises contacting the institution as soon as possible.
The Pix security guide and the MED FAQ explain that a fraud victim can already request a refund from their institution within 80 days after the original transaction. The September 1 change is specifically about contesting the refund transaction, which had a 30-day window in the previous manual.
What only changes on October 26: “graph depth” reaches the analysis stage
The other version 8.5 amendment is technical and mainly directed at participating institutions. The manual will add the TransactionDepth attribute, described as “graph depth,” to the infraction report for a refund request. BCB Normative Instruction No. 766 links the change to Sections 10.1 and 20.1.5.
The tracking graph represents the path through which funds are dispersed from the contested transaction. In the manual, the root transaction is the first layer; transactions made by the recipient of the root transaction form the second layer; and subsequent transactions form later layers. The new attribute indicates which of these layers contains the transaction being analyzed.
This adds operational context to the review of infraction reports, but the rule does not say that customers will see a new field called TransactionDepth in their banking app. The customer-facing effect is therefore likely to be indirect: the information is used in the DICT-to-participant flow to assess the path taken by the funds.
Why October 26 if Instruction 766 originally said August 10
The original wording of BCB Normative Instruction No. 766 set August 10, 2026 as the effective date for the changes to Sections 10.1 and 20.1.5. On July 30, before that date arrived, BCB Normative Instruction No. 767 amended Article 3 and moved this block to October 26, 2026. The same amendment moved the revocation of BCB Normative Instruction No. 752/2026 to October 26.
As a result, references that repeat the initial August 10 schedule are outdated. To determine what is in force now, the current consolidated version of Instruction 766 must be read, because it already incorporates the wording introduced by Instruction 767.
What users should do in each scenario
- You were the victim of a scam and sent the Pix: notify your institution immediately and ask it to activate the MED. The Central Bank maintains the guidance that the request can be registered within 80 days, but acting early improves the chance of finding funds.
- You legitimately received a Pix and a refund was processed in a fraudulent context: contact your institution, report the case and provide evidence. The rule in force since September 1 extends the window for contesting the refund transaction to 80 days, subject to the MED and Funds Recovery criteria.
- You are waiting for a visible app change on October 26: the rule does not promise a new customer screen or button. What takes effect is an additional data item in the technical notification and analysis flow.
Quick questions
Did an 80-day deadline begin for every type of contest on September 1?
No. The version 8.5 change highlighted here is the extension to 80 days for contesting a fraudulent refund transaction. The deadline for a victim to request the MED for the original transaction was already up to 80 days.
Does the new deadline apply to a commercial dispute?
Not by itself. The Central Bank states that the MED is intended for fraud, scams or certain operational failures and is not a mechanism for ordinary commercial disagreements.
What takes effect on October 26?
The changes to Sections 10.1 and 20.1.5, adding information about the transaction’s depth in the tracking graph through TransactionDepth, as well as the revocation of BCB Normative Instruction No. 752/2026.
Do the two dates come from the same rule?
The content came from BCB Normative Instruction No. 766, but the current schedule was adjusted by No. 767. The correct reading is: September 1 for Sections 20.1.1, 20.1.9 and 20.2; October 26 for Sections 10.1 and 20.1.5 and for the revocation of Instruction 752.
