Puerto Rico does not have a central bank and relies on the US Federal Reserve System (the Fed), the US central bank, as its central regulatory institution. It does not maintain its own reserves. Non-resident entities are permitted to hold fully convertible domestic and foreign currency bank accounts within Puerto Rico.
Puerto Rico’s unique status as a US territory is why many banks are moving to the island – Puerto Rico is growing at 24 banks a year. This is a staggering number and Act 273 licenses might surpass Cayman Islands in 2 or 3 years.
