As I understand it, some of the silver was siphoned off in trade with China (via the trans-Pacific route to Manila). China needed continuing silver imports because silver was not used there in the form of standardized coinage, but rather in ingots that were weighed and subdivided, with inevitable continuing loss.

It was very surprising to see zero mention of the Manila galleon[0] trade route in the linked article, even if technically the question was about gold rather than silver.

Southern Chinese traders migrated in greater numbers throughout the region, new world fruits and vegetables such as sweet potato and pineapple are introduced. Chinese merchants in the region are producing Christian religious art for export back to the old world, giving rise to a unique hybrid artistic style.[0] The region as a whole becomes more attractive for the Dutch and the British, which had its own set of downstream consequences …

I’m sorry I don’t have a single source that pulls this all together, you would probably need to pick an area and start reading!
