The Qatari Riyal (QAR) serves as the official currency of Qatar. It was introduced on May 19, 1973, replacing the Saudi Riyal at a conversion rate of 1 Qatari Riyal for 1 Saudi Riyal. The Qatar Central Bank is tasked with the issuance and management of the Qatari Riyal.

Essentially, the trading concept of Quantitative Analysis involves the application of business or financial techniques aimed at understanding behavior within the currency market. This is achieved through a complex system of mathematical and statistical modeling, alongside the measurement of market values and research.

Quantitative easing (QE) is an unconventional monetary policy employed by central banks to invigorate the economy when traditional monetary measures are ineffective. It is often informally referred to as “printing money,” although no physical banknotes are actually produced. Instead, money is electronically “created” or “keystroked.” Terms like “keystroking money” or “typing up money” are more precise than “printing money.” The goal of QE is to elevate the price of government bonds while simultaneously lowering their yields. This strategy encourages banks to invest in riskier assets and increase lending to businesses and individuals.

Quantitative Tightening (QT) is a monetary policy tool employed by central banks to decrease the liquidity or money supply in the economy. It essentially serves as the opposite of Quantitative Easing (QE), where central banks purchase financial assets like government bonds to boost the money supply, lower long-term interest rates, and encourage economic growth. The primary objective of QT is to control inflation and restore normal monetary policy following periods of QE.

The Quantity Theory of Credit is an economic theory that highlights the significance of credit creation by banks in shaping the overall money supply and the economy. This theory presents a different perspective compared to the traditional Quantity Theory of Money, which centers on the influence of the money supply on price levels and inflation. Developed by economist Richard Werner, the Quantity Theory of Credit asserts that the distribution of credit has a more immediate effect on economic growth and the overall health of an economy.

The Quantity Theory of Money is an economic concept that asserts that the overall price level of goods and services is directly related to the amount of money in circulation. This theory indicates that variations in the money supply will result in proportional changes in the general price level. As a fundamental aspect of classical economics, the Quantity Theory of Money has significantly shaped monetary policy throughout history.
