Generally speaking, when oil prices fall it is considered good for the economy as it unleashes excess consumer spending. This is what happened in the last big drop in 2014-2015. However, this time around, there are likely to be no winners from the drop. Because the huge fall in prices is coming at a time of significantly reduced economic demand because of the coronavirus, it is hard to imagine that much excess economic activity will be created to account for the drop in oil-related industries.
FINSUM: Supply and demand are tumbling simultaneously across the economy (not just in oil), so it does not seem this will be a net positive like it has been in the past.
