I mention this because between lunchtime on Wednesday January 24 and this past Wednesday, there was a distinct feeling of 'we made it'. Yes, inflation has surprised to the upside. Yes, key data were weak. Yes, central banks are pivoting more hawkishly. Yes, yields are rising. Yet, thanks to good earnings and fund inflows, global equities are only down 3%. Well done.

It's tempting to think that this is the end of the story: the test arrived early this year,and the markets passed. But the reality is likely to be more complicated. This is just the start of the game. A record amount of stimulus is about to be withdrawn from the global economy. It begins.

Part of the withdrawal will come through monetary policy. That shift has two parts: reversing the lowest policy rates in history, and reversing the largest central bank bond purchases in history. You know, simple stuff. From May 2022 to May 2023, Morgan Stanley economists expect G4 central bank balance sheets to shrink by US$2 trillion, four times the largest 12-month decline ever, from 2018-19.
