Probably not. A competent government could install temporary rationing for the most essential goods such as food. It happened through the the whole of the 1917—1920 Russian revolution, with four or five kinds of paper money being circulated around, and the urban population managed through it only if barely. That government was much less competent than the US government is today.
In the rural areas, mind you. That's one of the most appalling thing about famines in the XIX-XX, that they hit the countryside heavier than they hit the cities.
