PANews reported on June 5 that according to Cryptoslate, Henrique Videira, a senior executive of the Central Bank of Brazil, said at the Token Nation conference in Sao Paulo on June 4 that the transaction data of the central bank's digital currency Drex will be used as a direct input indicator for interest rate decisions. Each payment and asset transfer recorded in the Drex distributed ledger will generate a timestamped structured entry, and the central bank can monitor consumption changes, liquidity distribution and industry performance in real time by aggregating data. After internal desensitization, the data will be merged with the wholesale settlement flow to form a policy dashboard that tracks merchant category spending, collateral flows and regional trade volumes. Videira emphasized that Drex only stores hashed personal identifiers, and policy decision-making power still belongs to the Monetary Committee.

The Drex pilot was launched in March 2025, with 16 institutions testing tokenized Treasury bonds and deposit tokens. Full rollout is subject to Congressional approval of a bill submitted last month.
