What will gold be worth if the economy collapses? Nobody can reliably predict what gold would be worth if the economy collapsed. Its price would depend on the type of crisis, confidence in currencies, and whether markets continued functioning.
If a currency lost much of its value, gold could become far more expensive in that currency. However, a higher price would not necessarily mean greater purchasing power if food, housing, and other essentials also became much more expensive.
During a financial panic, gold can initially fall as investors sell assets to raise cash. In a broader breakdown, exchanging gold for necessities could depend on finding willing buyers and verifying its purity.
Gold may help preserve wealth through a crisis, but there are no guarantees of a specific price or level of protection.
