The practice of lending and borrowing is millenniums old. The concept of banking was incepted ever since humans started engaging in economic transactions of any kind. The banking system has evolved since then. We have well-established banks now in the 21st century-huge ones having more than $1 trillion in assets. The banking (or credit) sector is one that hold the reins of the world economy. Without the presence of a well-established credit-system, we cannot expect the economy to roll on. A dynamic banking system is essential for a thriving economy.
