What happens if the dollar undergoes hyperinflation? Does deposit APY go up to compensate?

What happens if the dollar undergoes hyperinflation? Does deposit APY go up to compensate? Also will I get better APY depositing USD or holding LUNA or ANC?

If hyperinflation happens the earth is going to 0. Every financial hub in the world is tied to the USD. There are more pressing things to worry about lol
