Some scholars believe that the origins of letters of credit go back to ancient Egypt and Babylon, which had an adequate system of banking. Rufus Trimble mentions a clay promissory note of Babylon dating from 3000 B.C., exhibited in the University Museum of Philadelphia, USA, which provided for repayment of an amount and the interest on a specific date. Wigmore refers to an evidence of an obligation made in 248 B.C. in Egypt “for the repayment, in wheat, or upon default double its value, of a loan of money from one Zenon, which ends with: ‘and the right of execution shall rest with Zenon and the person bearing the note on behalf of Zenon”. It is also verified that banks of ancient Greece prepared letters of credit “on correspondents with the view to obviating the actual transport of specie in payment of accounts”.
With the collapse of the Roman Empire the role of the banks as well as the great extent of commerce between trading nations diminished. It was not until the 12th and early 13th century that banks in Genoa, Venice, Florence and other European cities were re-established. At this time merchants had to face two major problems:
The earliest devices with which merchants tried to solve these problems were with the bills of exchange and letters of credit. In their early history these payment instruments operated in a very similar way, and letters of credit were used to supplement the bills of exchange.
In any case, it was impossible to conduct commerce via caravan without some sorts of documentary letters. To explain their early operation Professor Dolan gives the following example:
“… a Florentine merchant who bought wool from an Amsterdam merchant could issue a bill of exchange to the Dutch merchant’s agent in Florence directing a third party (the drawee) to pay the sum due for the wool. The agent, having taken the bill in payment for the wool, could travel across Europe or by sea to a commercial center, where he would meet the drawee and ask the drawee for payment.
The drawee would pay the draft either
De Roover also refers to letters of credit used by the Medici Bank in Bruges and in Italy between 1385 and 1401. The various provisions of the letters are strikingly similar to those of the modern letters of credit. They stated for example that
By the 19th century British banks had a virtual monopoly on the issuance of letters of credits. This was due to the fact that in world trade the Pound Sterling was the most accepted currency and the bankers of London gained a pre-eminent position in the field of international finance.
In the United States letters of credit emerged from the “competition of factorage houses for business, which led to the issuance of promises to accept drafts against shipments”. The growing number of manufacturers and their relationships with foreign traders, the specialization of banking activities and the technological development such as the more frequent use of telegraph for communicating the terms of the contracts facilitated the increasing use of letters of credit.
On the other hand, letters of credit were not used exclusively by merchants. Thomas Jefferson, third president of the US, wrote the following letter to Captain Meriwether Lewis in 1803 on the occasion of leading an expedition to explore the wild western territory:
“Dear Sir, In the journey which you are about to undertake for the discovery of the course and source of the Mississippi, and of the most convenient water communication from thence to the Pacific ocean [sic], your party being small, it is to be expected that you will encounter considerable dangers from the Indian inhabitants. Should you escape those dangers and reach the Pacific Ocean, you may find it imprudent to hazard a return the same way, and be forced to seek a passage round by sea in such vessels as you may find on the Western coast. But you will be without money, without clothes and other necessities, as a sufficient supply cannot be carried with you from hence. Your resource in that case can only be in the credit of the US, for which purpose I hereby authorize you to draw on the Secretaries of State, of the Treasury, of War and of the Navy of the US, as you may find your drafts will be most negotiable for the purpose of obtaining money or necessaries for yourself and your men. I solemnly pledge the faith of the United States that these drafts shall be paid punctually at the date they are made payable. I also ask of the Consuls, agents, merchants and citizens of any nation with which we have intercourse or amity to furnish you with those supplies which your necessities may call for, assuring them of honorable and prompt [unreadable]. And our own Consuls in foreign parts where you may happen to be, are hereby instructed and required to be aiding and assisting to you in more entire satisfaction and confidence to those who may be disposed to aid you, I , Thomas Jefferson, President of the United States of America, have written this letter of general credit for you with my own hand, and signed with my name.”
The outbreak of World War I broke the well-established and trusted trading links that had existed between the merchants worldwide. In order to keep on trading merchants were forced to create new links with firms often unknown or not trusted. These circumstances were favourable for the extensive use of letters of credit which invited a trustworthy paymaster, a bank, into the merchants” relationship. By the 1950”s letters of credit had earned a predominant position in domestic commerce of the United States and were also widely used in international transactions.
Since World War II the use of letters of credit in world trade remains steadfast. Although from time to time the emergence of alternative means of trade finance overshadows the use of the letter of credit, it has “proven to be a flexible instrument, which can be readily attempted to the needs of changing conditions in international trade”. As Kozolchyk points out “in a world of shrinking distances and increasing trade there will be a continuing need for such a highly reliable, … , and flexible means of payment and financing”
