In The Spanish Empire, Silver, & Runaway Inflation: Crash Course World History #25, it is claimed that
"In ..., the silver was pouring into Spain, and because they were collecting same taxes as 60 years before, that lead to inflation..."
If you watch the video, a similar situation happens in China; the government forces people to produce silk, and that lead the price drop, but that somehow also leads to inflation even though now the government has lots of silk which is quite valuable.
So, what is the reason for the inflation in both cases ? and how taxes related to the inflation in the Spanish case ?
