Thanks, Madam May. That's a very interesting question, and the answer is not straightforward.
The impact of stopping the stimulus will depend on the strength of the recovery and the speed of the recovery. If the recovery is strong and the engine is full speed ahead, then the impact of withdrawing economic support or stimulus would probably be minimal. In fact, it would be beneficial. It would avoid crowding out private sector investment and economic activity.
On the other hand, if the economic recovery does not materialize, then one could envisage economic support by the government to be needed. It may be at a lower level, because the economy will be reopened, but there might be scope or need for some level of support for more than right after the pandemic is over.
