The Baring crisis of 1890 was triggered when the London merchant bank Baring Brothers could not sell Argentine investments.
Baring Brothers had accumulated substantial exposure to Argentina during a period of heavy borrowing and political uncertainty. When confidence collapsed, the bank faced insolvency because it could not place the securities it held. A failure threatened wider panic in London and the international financial system.
The Bank of England organized a rescue fund with support from other banks and the French and Russian central banks. Baring Brothers was restructured rather than allowed to fail immediately. The episode showed how a major financial institution's foreign investments could transmit distress across borders.
The crisis is sometimes confused with the later Barings collapse of 1995, when trader Nick Leeson caused enormous losses through unauthorized derivatives trading. The 1890 event involved sovereign and commercial lending exposure, not Leeson's trading scandal.
