Qatari Riyal (QAR)
The riyal is the national currency of Qatar, carrying the ISO code QAR and issued by the Qatar Central Bank. Its defining feature for a trader is the peg: since 2001 the riyal has been fixed to the US dollar at a rate of 3.64, which means it does not float freely and its day-to-day moves against the dollar are essentially nil.
That stability is underwritten by Qatar’s enormous wealth in natural gas and oil, which fills the state’s reserves and gives the central bank the firepower to defend the peg. Like other Gulf pegs, it ties Qatari monetary policy loosely to the Federal Reserve, since holding the rate limits how far local interest rates can drift from US ones.
Example: During the 2017 diplomatic blockade of Qatar by several of its neighbours, the riyal briefly wobbled in offshore trading as nerves spiked, but the central bank leaned on its vast reserves and the official 3.64 peg held firm, so onshore the currency barely budged.
Quality spread differential (QSD)
The difference in yield between two fixed-income securities of different credit quality.
Quantitative Analysis
Quantitative analysis is the practice of evaluating markets, securities, and risk with mathematics, statistics, and computer models rather than judgment and narrative. Where a qualitative analyst weighs management quality or a company’s story, a quant builds a model, feeds it data, and lets the numbers point to a decision. It covers a huge range, from pricing derivatives and measuring portfolio risk to designing fully automated strategies that scan for statistical patterns across thousands of instruments at once.
The people who do this, quants, tend to come from backgrounds in mathematics, physics, and computer science, and their influence over modern markets is hard to overstate. The obvious danger is misplaced confidence: a model is only as good as its assumptions, and markets have a habit of breaking the patterns that looked rock-solid in a backtest.
Example: A systematic hedge fund uses quantitative analysis to spot pairs of historically correlated stocks that have temporarily diverged, then automatically buys the laggard and sells the leader, betting the relationship snaps back rather than relying on any view about either company.
Quantitative easing
Quantitative easing is what a central bank may use when it has already reduced interest rates. It creates new bank reserves electronically and uses them to buy financial assets, mostly government bonds and sometimes mortgage or corporate debt, from banks and investors. The aim is to push down longer-term yields, lift asset prices, and nudge money out of safe holdings and into lending and spending.
This is not cash handed to the public, despite the printing-press headlines; it is central-bank reserves, and it swells the bank’s balance sheet dramatically. QE remains controversial, praised for stabilising markets in a crisis and criticised for inflating asset prices in a way that may tend to reward people who already own things.
Example: After the 2008 financial crisis, the US Federal Reserve launched successive rounds of QE, buying Treasuries and mortgage-backed securities and expanding its balance sheet from under a trillion dollars to more than four trillion, then did much the same on an even larger scale during the 2020 pandemic.
Quantitative easing (QE)
One of the defining tools of modern central banking, quantitative easing, or QE, is classed as unconventional policy because it reaches beyond the usual lever of setting a short-term interest rate. When short-term interest rates are at or near their effective lower bound, a central bank can still ease by buying bonds in bulk with newly created reserves, aiming to influence long-term borrowing costs rather than the overnight rate.
The mechanism runs through several channels: lower yields on government debt may encourage investors to move into riskier assets, borrowing gets cheaper across the economy, and the signal that policy will stay loose shapes expectations. The genuinely hard part is the exit. Unwinding a vast balance sheet without jolting markets can be challenging.
Example: The Bank of Japan pioneered QE in the early 2000s, and the European Central Bank ran its own large-scale version from 2015, buying eurozone government bonds for years on end to fight the threat of deflation and bring inflation back up toward its target.
Quantitative Tightening (QT)
Quantitative tightening is quantitative easing thrown into reverse. Having bought vast quantities of bonds to stimulate the economy, a central bank eventually wants to shrink the balance sheet it built up, and QT is how it does that. The gentler method is runoff: as bonds mature, the bank simply declines to reinvest the proceeds and lets its holdings shrink over time. The more aggressive version is selling bonds outright into the market.
Either way, the effect is to reduce reserves and liquidity from the financial system, which can put upward pressure on longer-term yields and tighten conditions, the exact opposite of what QE was designed to do. The tricky part is that nobody fully knows how much liquidity can be pulled out before something in the plumbing breaks.
Example: The US Federal Reserve began quantitative tightening in 2022, allowing hundreds of billions of dollars of Treasuries and mortgage-backed securities to roll off its balance sheet each year as part of its broader fight against high inflation.
