Since the 1990s, trading with bank instruments is a well-established part of the global economy. The world's largest holding companies issue blocks of debt instruments such as Medium Term Notes, debentures, and standby letters of credit.
The genesis of this marketplace was the 1944 Bretton Woods Conference, attended by 730 delegates of the 44 allied countries of World War II. The conference's purpose was to establish a stable system of international finance. It is the system used today and economic stability is still the impetus for the operation of these transactions. These transactions started over fifty years ago and they have grown and continuously modified to meet modern needs and standards.
