WTO projections for global merchandise trade by volume:
Let's take a closer look. Optimistic scenario is for a 13% y/y drop in merchandise trade flows. Pessimistic one is for a 30% drop. Swing is 17 percentage points. These are not forecasts, but are uncertain guesses. We are in a VUCA world, folks.
Let's take a second look: COVID19 shock will be permanent (new trend line post-recovery is permanently below old trendline and flatter) with a minor impact post-2022 that will compound over longer period of time. In pessimistic scenario, the impact appears to be also permanent, but seriously severe.
On a linear trend projection, pre-2008 consistent trend would have left us at around 155 index reading in 2022. 2009-2019 trend would have gotten us to around 122 index reading. Optimistic scenario would leave us around 119 in 2022; pessimistic - at around 95. Wait... optimistic gap for COVID19 and GFC impacts to no GFC and no COVID19 impact is... 33 points! One third of 2015 annual level of trade activity. GFC but no-COVID19 gap to pre-2008 is between 36 points and 60 points.
And the final look: notice 2019 line... it is virtually flat. As WTO notes (see Chart 4 here: https://www.wto.org/english/news_e/pres20_e/pr855_e.htm) there was, basically, no growth in trade in 2019, before the COVID19 hit.
We are in a VUCA world, folks.
