Two major banks have gone down in Serbia and Paraguay within four days. And there are already connections to some of the biggest names in American banking. Paraguay’s Ueno Bank reported about $4.2 billion in assets and $2.8 billion in customer deposits as of June 2026. It also had $814 million in funding from financial institutions and capital markets, including a $350 million international bond offering arranged by JPMorgan and Bank of America. Ueno also listed Citibank and Bank of New York among its correspondent banks. These connections raise questions about how much money international institutions have at stake, but their actual exposure has not been disclosed.
The public money involved in Paraguay is another concern. Ueno held roughly $800–850 million in government and pension-related funds, including approximately $355 million belonging to the state pension and healthcare fund. That money is now caught up in the bank’s resolution process. Meanwhile, Serbia’s Alta Bank collapse has spread into neighboring countries. Its North Macedonian subsidiary faced restrictions, while Montenegro revoked the operating authorization of Alta Pay, a related payment company. Montenegro’s central bank says the country’s wider payment system remains stable.
🚨 BANKING SHOCK:
TWO BANKS COLLAPSE IN ONE DAY – MORE THAN 3 MILLION CUSTOMERS AFFECTED ACROSS TWO COUNTRIES.
🇷🇸 SERBIA – ALTA BANKA
• 66,481 customers (end-2025 data).
• €1.627 BILLION in customer deposits as of September 30, 2026.
• Banking licence revoked on October…— Mr. Whale (@MrWhale) November 5, 2026
It is still too early to tell whether either failure could put the U.S. banking system at risk. The full creditor list, bondholder exposure and international banking connections have not been made public. Two bank failures within four days, billions of dollars in reported assets and deposits, and American financial institutions connected to one of the failed banks deserve a closer look. If more hidden exposure comes to light, the fallout could be much larger.
