This paper deals with Anglo-Spanish trade and finances for the period c. 1810-1850. It concentrates on the business activities of a London merchant bank (Huth & Co. or Huth) with Spain during this period by paying special attention to the support given by Huth to the many bilateral trades between Spain and Britain in which the company participated. It also focuses on the support given by Huth to much trade in and out of Spanish ports but which did not go through British ports. This overall support included the provision of credit facilities, exchange rate brokerage, insurance services and commercial intelligence. In addition, the article covers the links between Huth and the Spanish crown, thanks to which the bank became an important conduit of Spanish investments in American securities before 1850. Huth was also the paymaster abroad for the Spanish state. In view of Huth's close connections to the Spanish economy during this period, it is perhaps surprising that this is the first study of this «Spanish» house in London.
