BTLP was a utility company which provided power and streetcar services in Barcelona; originally incorporated in Canada, it was mostly owned by Belgian investors. BTLP had come through the Spanish Civil War largely undamaged, and was quite profitable. Its assets were about £10,000,000 (about $500,000,000 in 2010). However, for the convenience of some of its foreign investors, BTLP had issued some bonds denominated in pounds, and the interest on these bonds was payable in pounds. The Spanish government had imposed currency restrictions: BTLP was unable to exchange its Spanish pesetas for pounds, and so could not pay the interest.
