This article represents the global economic impact of pandemics as about 6 trillion in losses over the course of the 21st century. But it is evidently a study of economic losses caused by the pandemics themselves, not lockdowns.
The global economic losses because of the pandemic LOCKDOWN is probably already 6 trillion.

We can see that our model estimates an average loss to the global economy of more than $60 billion per year—or more than $6 trillion per century. Again, an important feature of the distribution of expected economic losses is that they exhibit a long right tail; that is to say, there is a nontrivial chance of seeing much more extreme losses. For example, the model predicts a 10 percent chance that average losses this century will be more than $120 billion per year. Indeed, it is because our model accommodates for the possibility of these rarer but more extreme outcomes that our estimate of average losses is higher than the $30 billion calculated by the World Bank.
No model can perfectly predict the economic losses that will arise from future pandemics, and all models have their limitations.
