The United States of America
The Federal Reserve Act of 1913 led to the Federal Reserve Bank opening its doors in 1914. The country was divided into 12 Federal Reserve districts, each having jurisdiction over the commercial banks and bank holding companies located therein. With the Fed came greater uniformity in banking practices across the country, though some regional differences did persist. The Fed was initially limited both in its regulatory powers and in monetary policy tools; the only thing it could do to change money supply was to make/call in discount loans. It was also subject to significantly greater political control. Gradually the independence and scope of the Fed evolved, as it accidentally discovered open market operations, was given the authority to change the reserve ratio and reached The Accord with the Treasury that made it truly autonomous.
