What quantitative easing is
Quantitative easing (QE) is a policy in which a central bank creates new reserves and uses them to buy financial assets, mostly government bonds, from the market. Some central banks also buy mortgage bonds, corporate bonds or exchange-traded funds.
Central banks usually turn to QE when their main tool, the short-term policy rate, is already very low and the economy still needs support. QE works on longer-term interest rates, which the policy rate does not control directly.
For a quick refresher on how rates and currencies link, see Interest rates.
- The central bank buys government bonds with newly created money (QE).
- Bond yields fall and there is more money in the system.
- Holding the currency pays less than before.
- The currency tends to weaken; ending QE (tapering) usually works the other way.

What quantitative tightening is
Quantitative tightening (QT) is the reverse. The central bank shrinks the stock of assets it holds, which takes reserves out of the banking system. It can do this in two ways:
- Passive run-off: bonds mature and the central bank does not reinvest the money it receives.
- Active sales: the central bank sells bonds into the market before they mature.
Passive run-off is the more common approach because it is slower and easier for markets to absorb.
How QE and QT change the balance sheet
A central bank balance sheet has assets (what it owns) and liabilities (what it owes).
| Step | QE | QT |
|---|---|---|
| Assets | Bond holdings rise | Bond holdings fall |
| Liabilities | Bank reserves rise | Bank reserves fall |
| Bond supply left for investors | Smaller | Larger |
| Pressure on long-term yields | Downward | Upward |
| Typical policy stance | Easing (dovish) | Tightening (hawkish) |
When the central bank buys bonds, it pays sellers by crediting their banks' reserve accounts. This is why people say QE "prints money", although the new money sits mainly as bank reserves rather than cash in the street. The wider effect on deposits and lending shows up in money supply data.
The transmission channels
QE and QT reach the economy and markets through several routes:
- Yield channel: large purchases push bond prices up and bond yields down. QT does the opposite.
- Portfolio rebalancing: investors who sold bonds to the central bank look for other assets, such as equities, corporate debt or foreign bonds. This tends to support riskier assets during QE.
- Signalling: a QE programme tells markets the policy rate is likely to stay low for a long time. This links QE closely to forward guidance.
- Term premium: the extra return investors demand to hold long bonds tends to shrink under QE and widen under QT, which can change the shape of the yield curve.
QE, QT and forex: how currencies often react
The usual pattern is:
- QE lowers yields on a currency's bonds and makes holding that currency less attractive. The currency often weakens against currencies with higher or rising yields.
- QT removes that pressure and can support the currency, especially if other central banks are still easing.
This is not a fixed rule. Several things can change the reaction:
- Expectations: markets price announcements before they happen. If a QE programme is smaller than traders expected, the currency can rise on the news.
- Relative policy: forex is always a pair. What matters is how one central bank's balance sheet policy compares with the other's. If both are easing, the effect on the pair can be muted.
- Risk mood: QE can lift global risk appetite, which can weaken safe-haven currencies and support commodity currencies. See Risk-on, risk-off.
- Real yields: if QE raises inflation expectations while nominal yields fall, real interest rates drop further. This often matters for gold and the US dollar.
The US dollar has a special role because many assets worldwide are priced in it. Changes in the Federal Reserve's balance sheet can affect the US Dollar Index and funding conditions in emerging markets.
Which central banks use QE and QT
Large asset purchase programmes are mainly associated with:
Each publishes its decisions, balance sheet data and meeting schedule on its official website. For the Fed, the FOMC meetings page explains how statements and minutes are released. Dates for future meetings should be taken from each central bank's official calendar, not from secondary sources.
The State Bank of Pakistan works mainly through its policy rate and interest rate corridor rather than large-scale QE. The SBP rates and economy page covers that framework.
What to watch around QE and QT news
Traders who follow balance sheet policy usually track:
- Policy statements: changes to purchase pace, reinvestment rules or run-off caps.
- Press conferences and minutes: hints about when tapering (slowing purchases) or QT might start or end. The tone is often described as hawkish or dovish.
- Weekly or monthly balance sheet releases: published by central banks on their official sites.
- Bond auctions and yields: how easily the market absorbs extra supply during QT.
- Money market stress: signs that reserves are becoming scarce can lead a central bank to slow or stop QT.
The Economic calendar guide explains how to read release times and consensus figures. Only use data from official central bank feeds or statistics agencies, because figures quoted elsewhere can be outdated or rounded.
Risk note
Balance sheet announcements can move currencies, bonds and gold sharply in a short time, and spreads can widen around the release. Leveraged forex and CFD trading can lose money fast, and a well-understood policy mechanism does not tell you where prices will go. Read Risk management before trading around central bank events.
Pakistani readers should also know the local legal position. Per the SBP, remitting foreign exchange to overseas forex/margin/CFD platforms is not allowed through any payment channel (FERA s.5(1)). See Law and regulators for details.
Frequent questions
Is QE the same as printing money?
Not exactly. The central bank creates new reserves to buy assets. These reserves stay inside the banking system. Whether broader money and lending grow depends on how banks and borrowers respond.
Does QE always weaken a currency?
No. The effect depends on what markets already expected and what other central banks are doing. A smaller-than-expected programme can even strengthen the currency.
What is tapering?
Tapering means slowing the pace of new asset purchases. It is still QE, just at a lower speed. It often comes before purchases stop and QT begins.
Why do central banks prefer passive run-off for QT?
Letting bonds mature without reinvesting is gradual and predictable. Selling bonds outright adds supply quickly and can push yields up more sharply.
How is QE different from cutting interest rates?
A rate cut changes the short-term policy rate. QE targets longer-term yields and financial conditions through asset purchases. Central banks often use QE when the policy rate is already very low.
Where can I find official QE and QT data?
Each central bank publishes balance sheet data and meeting calendars on its official website. Use those primary sources rather than figures repeated in news or on social media.
