Interest rate

An interest rate is the rate at which interest is paid by borrowers (debtors) for the use of money that they borrow from lenders (creditors). Specifically, the interest rate is a percentage of principal paid a certain number of times per period for all periods during the total term of the loan or credit. Interest rates are normally expressed as a percentage of the principal for a period of one year, sometimes they are expressed for different periods such as a month or a day. Different interest rates exist parallelly for the same or comparable time periods, depending on the default probability of the borrower, the residual term, the payback currency, and many more determinants of a loan or credit. For example, a company borrows capital from a bank to buy new assets for its business, and in return the lender receives rights on the new assets as collateral and interest at a predetermined interest rate for deferring the use of funds and instead lending it to the borrower.

Interest-rate targets are a vital tool of monetary policy and are taken into account when dealing with variables like investment, inflation, and unemployment. The central banks of countries generally tend to reduce interest rates when they wish to increase investment and consumption in the country's economy. However, a low interest rate as a macro-economic policy can be risky and may lead to the creation of an economic bubble, in which large amounts of investments are poured into the real-estate market and stock market. In developed economies, interest-rate adjustments are thus made to keep inflation within a target range for the health of economic activities or cap the interest rate concurrently with economic growth to safeguard economic momentum.

Khan Academy

Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.

History

The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.

In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.

Federal Reserve System

The Federal Reserve System‍—‌also known as the Federal Reserve or simply as the Fed‍—‌is the central banking system of the United States. It was created on December 23, 1913, with the enactment of the Federal Reserve Act, largely in response to a series of financial panics, particularly a severe panic in 1907. Over time, the roles and responsibilities of the Federal Reserve System have expanded, and its structure has evolved. Events such as the Great Depression in the 1930s were major factors leading to changes in the system.

The U.S. Congress established three key objectives for monetary policy in the Federal Reserve Act: maximizing employment, stabilizing prices, and moderating long-term interest rates. The first two objectives are sometimes referred to as the Federal Reserve's dual mandate. Its duties have expanded over the years, and as of 2009 also include supervising and regulating banks, maintaining the stability of the financial system and providing financial services to depository institutions, the U.S. government, and foreign official institutions. The Fed conducts research into the economy and releases numerous publications, such as the Beige Book.

Capital market

Capital markets are financial markets for the buying and selling of long-term debt or equity-backed securities. These markets channel the wealth of savers to those who can put it to long-term productive use, such as companies or governments making long-term investments. Capital markets are defined as markets in which money is provided for periods longer than a year. Financial regulators, such as the UK's Bank of England (BoE) or the U.S. Securities and Exchange Commission (SEC), oversee the capital markets in their jurisdictions to protect investors against fraud, among other duties.

Modern capital markets are almost invariably hosted on computer-based electronic trading systems; most can be accessed only by entities within the financial sector or the treasury departments of governments and corporations, but some can be accessed directly by the public. There are many thousands of such systems, most serving only small parts of the overall capital markets. Entities hosting the systems include stock exchanges, investment banks, and government departments. Physically the systems are hosted all over the world, though they tend to be concentrated in financial centres like London, New York, and Hong Kong.

Wall Street

Wall Street is a 0.7-mile-long (1.1 km) street running eight blocks, roughly northwest to southeast, from Broadway to South Street on the East River in the Financial District of Lower Manhattan, New York City. Over time, the term has become a metonym for the financial markets of the United States as a whole, the American financial sector (even if financial firms are not physically located there), or signifying New York-based financial interests.

Anchored by Wall Street, New York City has been called both the most economically powerful city and the leading financial center of the world, and the city is home to the world's two largest stock exchanges by total market capitalization, the New York Stock Exchange and NASDAQ. Several other major exchanges have or had headquarters in the Wall Street area, including the New York Mercantile Exchange, the New York Board of Trade, and the former American Stock Exchange.

History

Early years

There are varying accounts about how the Dutch-named "de Waal Straat" got its name. A generally accepted version is that the name of the street was derived from an earthen wall on the northern boundary of the New Amsterdam settlement, perhaps to protect against English colonial encroachment or incursions by Native Americans. A conflicting explanation is that Wall Street was named after Walloons— the Dutch name for a Walloon is Waal. Among the first settlers that embarked on the ship "Nieu Nederlandt" in 1624 were 30 Walloon families. The Dutch word "wal" can be translated as "rampart". However, even some English maps show the name as Waal Straat, and not as Wal Straat.
