Quantitative Easing / Tapering (QE)

Quantitative Easing

A policy where the central bank buys government bonds and other assets in bulk to release money into the market (QE), and gradually reducing those purchases (tapering).

In plain terms

When cutting rates to 0% does not revive the economy, the central bank directly buys assets like government bonds in bulk to release money — that is quantitative easing. It is like turning the tap on wider.

Tapering is not closing the tap but "gradually reducing how much it is turned on." It is not recalling money but slowing the pace of releasing it.

What it tells you

It shows how actively the central bank is trying to prop up the economy (QE) or starting to withdraw support (tapering).

As a big flow of market liquidity (the amount of money) rising and falling, it sways the environment for asset prices broadly — stocks, bonds, and more.

Formula

no set formula — when the central bank buys government bonds and other assets in the market (QE), money is released in the amount of those purchases.
gradually reducing the purchase size = tapering (slowing the pace of easing).

What high or low means

When QE releases money, rates tend to stay low and the environment tends to favor risk assets (stocks).

When a tapering signal comes, it is taken to mean "the money supply will soon tighten," and the market sometimes swings in advance (the past "taper tantrum").

Caution

QE is not all-powerful. Released money may not flow into the real economy and only lift asset prices, or come back later as a price (inflation) burden.

Tapering differs from "recalling money (tightening)." It is only the stage of slowing the pace of release, but it is easily mistaken for tightening.

Being a macro environment, it affects individual companies with a lag. Read the big flow rather than reacting to a single release.

Story

After the 2008 global financial crisis, having cut rates near 0% and still finding it insufficient, the Fed deployed quantitative easing in earnest, buying government bonds and mortgage-backed securities on a large scale. It did so again on a large scale during the 2020 COVID crisis.

In 2013, when the Fed signaled it would reduce the size of QE (tapering), emerging markets swung sharply — this is called the "taper tantrum." It is a case showing that even just slowing the pace of releasing money makes markets react sensitively.
