These are the shabby operators of the marginal shadows of the world of finance. They broker financial deals with meretricious sweat only to be rewarded their meagre, humiliated fees. Most of their deals do not materialize. The principle is very simple:
They approach a bank, a financial institution, or a borrower and say: "We are connected to banks or financial institutions in the West. We can bring you money in the form of credits. But to do that - you must first express interest in getting this money. You must furnish us with a bank guarantee / promissory note / letter of intent that indicates that you desire the credit and that you are willing to provide a liquid financial instrument to back it up.". Having obtained such instruments, the shoppers begin to "shop around". They approach banks and financial institutions (usually, in the West). This time, they reverse their text: "We have an excellent client, a good borrower. Are you willing to lend to it?" An informal process of tendering ensues. Sometimes it ends in a transaction and the shopper collects a small commission (between one quarter of a percentage point and two percentage points - depending on the amount). Mostly it doesn't -and the Flying Dutchman resumes his wanderings looking for more venal gulosity and less legal probity.
