Quantitative easing
Monetary policy instrument in which central banks purchase bonds on a large scale.
In brief: Monetary policy instrument in which central banks purchase bonds on a large scale.
Meaning in practice
QE depresses long-term interest rates, expands the central bank balance sheet and supplies the banking system with liquidity. It was the central response to the crisis after 2008 and during the pandemic – with far-reaching consequences for stocks, real estate and inflation.
Context for investors and traders
For traders, this term is most useful when preparing and executing an order. Its meaning depends on the venue, liquidity, time frame and order type. A single reading is not a reliable buy or sell decision.
How to use this in practice
In practice, the term should be linked to a specific trading plan: entry, exit, position size and costs belong together. In short time frames, spread, slippage and delayed execution can quickly outweigh the theoretical benefit of an observation.
What to keep in mind
Write down which observation confirms or invalidates your assumption before trading. This keeps the term a decision-making tool rather than a retrospective justification for risk already taken.
