Interesting use of the term, bond.
From the wikipedia page on margin (finance):
A performance bond can also be known as a surety bond. Now, we are in the land of the law of sureties.The collateral for a margin account can be the cash deposited in the account or securities provided, and represents the funds available to the account holder for further share trading. On United States futures exchanges, margins were formerly called performance bonds.
Also concerning performance bonds:
Good faith money is also known as earnest penny, Arles penny, or God's silver (in Latin Argentum Dei) ... an offering or token used to bind a bargain.The term is also used to denote a collateral deposit of good faith money, intended to secure a futures contract, commonly known as margin.
Now that I think more about it, one's estate of their worldly possessions or one's property (collateral) acts as a "performance bond" to one's debts bound therein.
FDIC, sureties, performance bonds, collateral .... all have to do with risk management and transference.
