I was surprised to see this headline at mises.org, but this is a rare departure from rhetorical convention. When a question is used as the title of an article, the answer is virtually always "Yes".

In this case, it's, "No, increases in the supply of gold cannot lead to boom-bust cycles":

The increase in the supply of gold has nothing to do with business cycles, as an increase in the supply of gold is an increase of wealth. This wealth increase does not result in an exchange of nothing for something.
