The U.S. Treasury designated the A7 Network a significant transnational criminal organisation on October 1, the same day dollar borrowing costs hit a level unseen in more than two decades. The stories are separate, but banks, remittance firms and governments across Latin America will find them on the same desk.
Treasury describes A7 as a Russia-linked shadow-banking network that the Iranian regime uses to move money around sanctions. Its notice named no Latin American institution. But a proposed ban on transfers involving A7 sub-agents would widen screening for regional banks, remittance firms and dollar-clearing desks. They’re not named in the notice, but the proposal could still affect their checks.
What Treasury Did
The October 1 action had three parts. The Financial Crimes Enforcement Network proposed a rule barring fund transfers involving A7 sub-agents and issued an alert for financial institutions. The Office of Foreign Assets Control made the criminal-organisation designation.
The numbers are large. Treasury said A7 claims more than 2,000 transactions a day and historic volume above 7.5 trillion roubles, about US$91.5 billion. A7 says it handled about 13% of Russia's foreign-trade transactions in 2025. FinCEN found that sub-agents processed more than US$17 billion from January 2025 to June 2026. Treasury linked the network to Iranian oil sales and weapons procurement.
Treasury Secretary Scott Bessent said the department was dismantling financial infrastructure that adversaries use to evade sanctions. Facilitators, he said, would lose access to the U.S. financial system. That’s the stated aim.
A separate Treasury action on September 29 hit 21 individuals and 25 companies tied to the Sinaloa Cartel. Those sanctions target Mexico.
Borrowing Costs and Prices
The U.S. 10-year Treasury yield touched about 5.34% on October 1, its highest since April 2002. It eased to a close near 5.24%, against 5.291% on Wednesday. That yield influences mortgage rates and emerging-market funding costs. Stocks barely noticed: the S&P 500 rose 0.19% to 7,666.45, and the Dow gained 0.04%.
The price data offered less comfort. The Institute for Supply Management said its U.S. manufacturing prices index rose to 77.9 in September from 71.1 in August. Forecasters had expected 72.3. The headline manufacturing index slipped to 54.5 from 54.6, below the 55.0 forecast, though new orders rose to 55.3 and employment to 52.7.
A U.S. intelligence brief said the 77.9 reading, along with a forecast of 3.7% annual U.S. inflation in the October 14 report, made a rapid decline in yields harder to expect. The prior reading was 3.4%. Meanwhile gold rose 0.63% to US$4,182 an ounce and the dollar index climbed to 102.014. The global briefing tied that pairing to demand for dollar liquidity and gold hedges.
The Jobs Test and Latin America
The September jobs report was due Friday at 13:30 Lisbon time. EODHD's calendar forecast 90,000 new jobs, down from 162,000 in August, with unemployment at 4.1%. Private payrolls were forecast at 85,000 against 127,000 previously. Government payrolls were seen at 15,000 against 35,000. Participation was forecast at 61.4%, down from 61.6%, and U-6 unemployment at 7.7%, unchanged.
For Brazil, the stakes carry a political edge. The global briefing said a softer jobs reading could ease the dollar and the pressure on the Brazilian real. A stronger one could lift the dollar ahead of Brazil's presidential election, which it identified as a key risk factor for Latin American markets. On October 1, USD/BRL stood at 5.2176, up 0.84%, while the Ibovespa closed at 187,197, up 0.46%.
The briefing described the 10-year yield as a benchmark for Brazil, Mexico, Colombia and dollar issuers from Chile to the Caribbean. The Federal Reserve meets October 27 and 28.
Why This Matters:
A 10-year yield near 5.24% doesn’t stay on Wall Street. By the source's own account, it shapes mortgage rates and the cost of funding for emerging economies, so households and governments with the least room to absorb higher costs feel it first. Rising factory prices and a softer jobs forecast add to that strain. The A7 rule shows public institutions policing opaque financial channels, but wider screening could also reach regional banks and remittance firms that serve ordinary customers. Nothing in the reports says those firms are implicated. The reports also announced no new Canada–Latin America agreement. Who bears the compliance burden, and how borrowing costs move after the Fed's late-October meeting, will help show how these pressures are shared.
