IMF forecasts
UK GDP fall will be 9.8% by EOY
Italy & Spain even worse, India too
For 2021, UK forecast is only a partial recovery of 5.9%, so the economy would still be smaller than 2019
However, I don't see if they included the likely effect of v hard Brexit / No Deal on top of Covid 
Global economy predicted to contract by 4.4%, followed by rebound of 5.2% in 2021,
so a deep but short V-shaped ~3 year recession remains likely globally and in many Western countries

The IMF warns that the global recovery is not assured while the pandemic continues to spread.
Research the agency published last week suggested that the downturn was only partly attributable to lockdown restrictions on activity imposed by governments.
Much of it reflected voluntary social distancing by people reluctant to do things that expose them to increased risk of infection.
The implication of that is that a complete recovery needs more decisive progress in tackling the virus, such as a vaccine.
The report says that most economies will suffer lasting damage.
There is likely to be what it calls "a major setback to living standards relative to what was expected before the pandemic".
The IMF warns that extreme poverty is likely to rise for the first time in more than twenty years.
Inequality is also likely to increase, the report says.
The crisis has particularly affected women, people with precarious employment, and those with relatively lower educational attainment.
