Indianomics: With the lockdown extended, should we prepare for even slower economic growth?

Should we prepare for an even slower economic growth this year due to the further extension of the lockdown in the red zones, which include many of the large cities like Mumbai, Bengaluru and Delhi? What options does the government have as tax collections fall? With deficits rising, is rating downgrade a real fear or is it exaggerated? As the economy contracts, can there be large scale loan defaults and will that slow the economy even more or does the Reserve Bank of India (RBI) have enough tools in its arsenal?
