reserve requirements

(FINANCE) the amount of bank reserves that a bank must keep in storage to meet unexpected liabilities.

Banks are not allowed to lend out 100% of the money they receive as deposits; if they did, then depositors would be unable to take money out of the bank. On the other hand, the bank has to lend most of the money out, since it needs the income earned from interest on loans. Throughout the history of the Usonian banking system, the US states or the federal government have had rules about interest rates, reserves, and financial accounting used by banks.

Reserve requirements are necessary to mitigate the risk of bank runs; this was thought to have disappeared thanks to deposit insurance, but Washington Mutual experienced a bank run in 2008 that forced it into receivership.
In the USA, reserves have been set by law for centuries; as a percentage of liabilities, this percentage has declined over the centuries to its current level of 3-10% (as of 1992). In the Eurozone, this rate is 2%; in Japan, it is about 1.5%; and in Commonwealth countries like the UK & Canada, it is voluntary--there are no reserve requirements.

external balance

the current account balance; the net flow of liquid assets to the citizens of a particular country. The external balance includes the trade balance, net foreign factor income, and net foreign aid *received*. Usually the main cause of an external deficit is a trade deficit.
External balances are critical to good economic policies.

option

(FINANCE) a type of financial derivative; a certificate that gives the owner the right to buy (or sell) a fixed amount of a specific thing for a specific price (the strike price).

An option to buy something else is called a call option; an option to sell something else is called a put option. An option has a strike price, which is the price at which you are entitled to buy (or sell) the underlying commodity, or stock, or foreign currency, or whatever.

Options allow the owner to speculate in the possibility that market prices will change in a certain direction, without actually spending the value of the underlying item. For example, suppose WTI crude is $85.75/bbl. In order to make $1000 off of a $0.25 increase in the price, you ordinarily would need to own 4000 bbls of crude, which you can't afford. So, instead, you buy a call option for 4000 bbls with a strike price of $85.75/bbl (i.e., exactly what it is now). This option will cost a tiny amount of money. If the price goes up to $86.00/bbl, you don't own the oil, but your options are now worth $1000 to somebody who wants to buy that oil.

An option with intrinsic value (for example,a call option whose strike price is less than the spot price) is "in the money." An option with no intrinsic value is "out of the money."
BILL: So, options are just like gambling, am I right?

ANNA: For most people. But if you're already in the business of buying or selling a particular thing, an option can protect you against a bad price movement.

BILL: But options on stocks? I mean, unless a company wants to reward its own executives, or something?

ANNA: Well, you might need options on stocks to hedge risk, if you're a fund manager. That way you can focus on long-run investing.

bank of issue

(ECONOMICS) A bank that is empowered to issue currency. In the USA, between 1863 (National Bank Act) and 1935, any bank with a federally issued charter (i.e., a national bank) was allowed to issue currency. After 1914, few did.

The US Treasury issued a small number of banknotes until 1971.

In the UK, banknotes of the Bank of England are legal tender; but the Royal Bank of Scotland is also a bank of issue.

Today, in almost every country of the world, the sole bank of issue is the central bank of that country.
The People's Bank of China is the bank of issue for the People's Republic of China.

trade balance

the amount of goods and services that a country exports, minus the goods and services that it imports *in a calendar year*. In 1999 Japan exported much more than it imported, so it had a trade surplus. The same year, the United States imported more than it exported, and therefore had a large trade deficit.

The trade balance is negative if a country runs a trade deficit, and positive if it runs a trade surplus.
The trade balance is an extremely important indicator of economic health for most countries. Typically (not not always) the value of the currency is strongly influenced by the trade balance also.

insolvency

(ECONOMICS) crisis created when a government or firm cannot pay its obligations in any reasonable time frame. Often confused with illiquidity, which is a when an entity suffers a temporary shortage of cash.

When a firm has assets that are greater than liabilities, it is solvent. In a lot of cases, the management of a firm runs out of ways to make money with the assets it has, so it "invests" in poor quality assets with high risk of default (for example, by lending money to borrowers using inflated housing prices as collateral).
Most of the time, insolvency is the result of corrupt or feckless management. In a few cases, however, it can be the result of a vicious cycle in which a well-managed company's customers all become insolvent first.

dirty float

In economics, a monetary policy in which the value of the local currency is determined by the foreign exchange markets, with some intervention by the government (or its allies) in the event of excessive or dangerous movements.

Usually the term is applied when the country ignores long term shifts in value, but intervenes directly to avoid crises.
Most of the nations in the world have neither a hard peg nor floating currency, but something in between--a dirty float, in which trade is under some restrictions.
