You have just trimmed the Spanish income in the decades before terrible crisis. In this ATL, Eighty Years War ends faster but still catastrophically to Spain. In later stages of war, Spain strongly relied on mercenaries, and lack of gold therefore directly translates to military defeats. Stronger Dutch East Indies and may be formation of Belgium is averted, OTL Belgium being instead firmly part of Netherlands?? Colonial empires balance is not much disrupted though, and no Belgium mean the Congo area in Africa remain not colonised for longer, may be taken by some other marginal colonial power like Germany, Russia or even Poland.
