Unlike in the past, this comes at a time when markets are at their peak.
Tightening has tamed inflation by the Fed selling the Treasury bonds it bought, driving down their price. Lower bond prices automatically mean higher yields, making it more expensive for companies and households to invest and borrow. This is the opposite of the quantitative easing that central banks have turned on in crises when they wanted, on the contrary, to kick-start investment activity and household consumption.
When the US Fed's entire balance sheet grew to nine trillion dollars, the central bank slowly began to tighten it. Eventually, it was able to reduce it significantly to around USD 6.5 trillion. That is a noticeable reduction, but we are still at twice where we were before the covid pandemic broke out.
Already on 29 October, the Fed announced that it was ending the tightening and turning the rudder. Technically, it says it will not ease, but bond purchases will still occur. In fact, it will be sending the proceeds of the mortgage bonds that it has also been buying and also owns into US bonds. And that must necessarily have an effect on their price and therefore on their yield. That, in turn, is what the markets like.
