Foreign exchange controls

Foreign exchange controls are various forms of controls imposed by a government on the purchase/sale of foreign currencies by residents or on the purchase/sale of local currency by nonresidents.

Common foreign exchange controls include:
Banning the use of foreign currency within the country
Banning locals from possessing foreign currency
Restricting currency exchange to government-approved exchangers
Fixed exchange rates
Restrictions on the amount of currency that may be imported or exported

Countries with foreign exchange controls are also known as "Article 14 countries," after the provision in the International Monetary Fund agreement allowing exchange controls for transitional economies. Such controls used to be common in most countries, particularly poorer ones, until the 1990s when free trade and globalization started a trend towards economic liberalization. Today, countries which still impose exchange controls are the exception rather than the rule.

Foreign-exchange reserves

Foreign-exchange reserves (also called forex reserves or FX reserves) in a strict sense are 'only' the foreign currency deposits and bonds held by central banks and monetary authorities. However, the term in popular usage commonly includes foreign exchange and gold, Special Drawing Rights (SDRs) and International Monetary Fund (IMF) reserve positions. This broader figure is more readily available, but it is more accurately termed official international reserves or international reserves. These are assets of the central bank held in different reserve currencies, mostly the United States dollar, and to a lesser extent the euro, the pound sterling, and the Japanese yen, and used to back its liabilities, e.g., the local currency issued, and the various bank reserves deposited with the central bank, by the government or financial institutions.
History

Official international reserves, the means of official international payments, formerly consisted only of gold, and occasionally silver. But under the Bretton Woods system, the US dollar functioned as a reserve currency, so it too became part of a nation's official international reserve assets. From 1944–1968, the US dollar was convertible into gold through the Federal Reserve System, but after 1968 only central banks could convert dollars into gold from official gold reserves, and after 1973 no individual or institution could convert US dollars into gold from official gold reserves. Since 1973, no major currencies have been convertible into gold from official gold reserves. Individuals and institutions must now buy gold in private markets, just like other commodities. Even though US dollars and other currencies are no longer convertible into gold from official gold reserves, they still can function as official international reserves.

Purpose

In a flexible exchange rate system, official international reserve assets allow a central bank to purchase the domestic currency, which is considered a liability for the central bank (since it prints the money or fiat currency as IOUs). This action can stabilize the value of the domestic currency.

Central banks throughout the world have sometimes cooperated in buying and selling official international reserves to attempt to influence exchange rates. This coordinated strategy was used to replace pound sterling with US dollar as the world reference currency during the 20th century.[1] The lack of such international cooperation is also a big concern for the replacement of US Dollar in this role of reference currency in foreign exchange reserves.

Financial market news is now being formatted by firms such as Need To Know News, Thomson Reuters, Dow Jones, and Bloomberg, to be read and traded on via algorithms.

"Computers are now being used to generate news stories about company earnings results or economic statistics as they are released. And this almost instantaneous information forms a direct feed into other computers which trade on the news."

The algorithms do not simply trade on simple news stories but also interpret more difficult to understand news. Some firms are also attempting to automatically assign sentiment (deciding if the news is good or bad) to news stories so that automated trading can work directly on the news story

"Increasingly, people are looking at all forms of news and building their own indicators around it in a semi-structured way," as they constantly seek out new trading advantages said Rob Passarella, global director of strategy at Dow Jones Enterprise Media Group. His firm provides both a low latency news feed and news analytics for traders. Passarella also pointed to new academic research being conducted on the degree to which frequent Google searches on various stocks can serve as trading indicators, the potential impact of various phrases and words that may appear in Securities and Exchange Commission statements and the latest wave of online communities devoted to stock trading topics.

"Markets are by their very nature conversations, having grown out of coffee houses and taverns", he said. So the way conversations get created in a digital society will be used to convert news into trades, as well, Passarella said.

“There is a real interest in moving the process of interpreting news from the humans to the machines” says Kirsti Suutari, global business manager of algorithmic trading at Reuters. "More of our customers are finding ways to use news content to make money."

An example of the importance of news reporting speed to algorithmic traders was an advertising campaign by Dow Jones (appearances included page W15 of the Wall Street Journal, on March 1, 2008) claiming that their service had beaten other news services by 2 seconds in reporting an interest rate cut by the Bank of England.

In July 2007, Citigroup, which had already developed its own trading algorithms, paid $680 million for Automated Trading Desk, a 19-year-old firm that trades about 200 million shares a day. Citigroup had previously bought Lava Trading and OnTrade Inc.
