I want to know the answer to the following question:
How long did the inflationary pressure continue?
All the background I'm provided with is that "At those times when John was preparing for campaigns in Normandy, for example, huge quantities of silver had to be withdrawn from the economy and stored for months, which unintentionally resulted in periods during which silver coins were simply hard to come by, commercial credit difficult to acquire and deflationary pressure placed on the economy.". Is that enough to answer the question?
Answer: no
