Money acts as a standard measure and a common denomination of trade. The use of barter-like methods may date back to at least 100,000 years ago, though there is no evidence of a society or economy that relied primarily on barter. Instead, non-monetary societies operated largely along the principles of gift economy and debt. When barter did in fact occur, it was usually between either complete strangers or potential enemies.
And so it was that the “Swiss” dinar for a period of about 10 years, even without government backing or any law establishing it as legal tender, served as northern Iraq’s fiat money.

Brokerage firms have the right to set their own maintenance margin requirements—often called “house” requirements—as long as they’re more stringent than the margin requirements under FINRA rules. These enhanced requirements can apply broadly or to particular stocks. For example, firms can raise their maintenance margin requirements for specific volatile stocks to ensure there are sufficient funds in their customers’ accounts to cover large price swings. FINRA rules supplement the requirements of Regulation T by placing “maintenance” margin requirements on customer accounts. Under these rules, as a general matter, the customer’s equity in the account must not fall below 25 percent of the current market value of the securities in the account.

However, the instability in the ratio between the two grew over the 19th century, with the increase both in the supply of these metals, particularly silver, and of trade. This is called bimetallism and the attempt to create a bimetallic standard where both gold and silver backed currency remained in circulation occupied the efforts of inflationists. Governments at this point could use currency as an instrument of policy, printing paper currency such as the United States greenback, to pay for military expenditures. They could also set the terms at which they would redeem notes for specie, by limiting the amount of purchase, or the minimum amount that could be redeemed. Many items have been used as commodity money such as naturally scarce precious metals, conch shells, barley, beads, etc., as well as many other things that are thought of as having value.
