"Gemflation" on Roshar

On Roshar, gems are used for a myriad of purposes; currency, fabrials, investure transport, information storage, Soulcasting. Despite the many purposes, gems (or Spheres when encased) have a primary use as a storage of value.

With that said, are gems inflationary or deflationary?

The current influx of gems primarily comes from the local fauna, and the outflux of gems only occurs when they are destroyed (otherwise it is simply a transfer of value). From memory, gems are 'destroyed' in Soulcating and information storage. There are likely others I am not thinking of right now.

So what do you think, has there been any WoBs on this topic? Does Roshar see more gems created than destroyed - are gems inflationary or deflationary?
