What is “yield curve control” and why is it coming to a central bank near you?

Central banks around the world are determined not to let interest rates go up too quickly or by too much – a practice known as “yield curve control”. John Stepek explains why it’s happening, and what it means for you.

On Saturday, Joe Biden’s big stimulus package cleared its first major political hurdle. The US House of Representatives gave the go-ahead to the $1.9trn coronavirus relief package. It now needs to get passed the Senate. The US has already spent 16.7% of GDP on measures to help the economy, notes Capital Economics. This would push it up to as much as 25%. That’s way bigger than in the eurozone, for example. It’s small wonder that investors are starting to worry about inflation.

As Neil Shearing of Capital Economics points out, not only is fiscal stimulus bigger in the US, the “degree of economic slack” is probably smaller than in the eurozone too. So you’ve got a big demand hit coming, and supply isn’t necessarily there to handle it. So you can see why bond investors are a bit rattled.
