Central banks and police tighten payment rules—will fraud controls reshape money flows overnight?

Brazil’s central bank is considering operational changes to Pix, including requiring financial institutions to perform longer fraud screening before crediting accounts, potentially up to 72 hours for high-value transfers. The proposal is aimed at reducing fraud losses by slowing down the moment funds become available, especially during overnight periods when criminals often exploit weaker monitoring. The move signals a shift from purely real-time confirmation toward a risk-based “hold and analyze” model for certain transactions. If adopted, it would effectively change how quickly recipients can access liquidity after a transfer, with direct implications for consumer behavior and corporate treasury operations. Russia’s Ministry of Internal Affairs (MVD) meanwhile issued guidance on a common scam pattern: when money arrives from an unknown person, victims should immediately contact their bank and determine the source of the transfer rather than attempting to return funds themselves. The instruction also emphasizes preserving related chat logs and correspondence, which can be critical for tracing the fraud chain and supporting claims. Separately, a study cited by Kommersant from the system integrator “Infosystems Jet” suggests that anti-fraud protections are far stronger for remote banking services than for in-branch operations, implying that criminals may still find more exploitable gaps at physical counters. Together, these measures indicate a coordinated tightening of payment integrity across both policy and enforcement, with regulators pushing banks to improve controls and investigators pushing victims toward evidence preservation. On the market side, the Russian data point that the share of foreign-currency inflows to accounts of small exporters rose to 23.2% in the first half of 2025 is a meaningful macro-financial signal. At the same time, the share of incoming ruble transfers from foreign counterparties to micro and small exporters fell to 76.8%, the lowest since the second half of 2022, suggesting a gradual shift in invoicing and settlement preferences. If fraud controls and transaction holds increase friction in domestic payment rails, exporters may further prefer channels that minimize delays, potentially reinforcing currency diversification. For investors, these dynamics can affect expectations for ruble liquidity, trade settlement volumes, and the relative demand for FX hedging instruments. What to watch next is whether Brazil’s central bank formalizes the 72-hour analysis/retention requirement and defines which transaction categories qualify as “high value,” as that will determine the immediate impact on Pix usage and short-term cash management. In Russia, monitor whether banks adjust staffing and controls at branches to close the gap highlighted by the Infosystems Jet research, and whether MVD guidance leads to more standardized victim response workflows. For the exporter settlement trend, track subsequent quarterly data from “Tocka Bank” or similar sources to see if the FX share continues rising or stabilizes. Trigger points include any regulatory deadlines for implementation, measurable changes in fraud loss rates, and shifts in FX settlement shares that could influence near-term FX volatility and hedging demand.

Geopolitical Implications

• 01

  Payment-system governance is becoming a cross-border policy priority, with regulators using transaction timing and evidence-based enforcement to reduce fraud-driven financial instability.

• 02

  Tighter settlement controls can indirectly influence trade finance behavior, encouraging exporters to diversify settlement currencies and potentially alter FX demand and hedging strategies.

• 03

  The branch-versus-remote security gap highlights how physical access points remain a strategic vulnerability for criminal networks, shaping future bank compliance and staffing priorities.

Key Signals

• —Brazil: publication of draft rules defining which Pix transactions qualify for up to 72-hour retention and the operational timeline for banks.
• —Russia: measurable reduction in fraud losses at branches and whether banks upgrade counter controls, authentication, and staff procedures.
• —Russia: next quarterly data on ruble vs FX inflows for micro and small exporters to confirm whether the FX share continues rising.
