Effects on Spain Without Inca Conquest

I'm writing a TL right now where the Incas are not conquered by the Spaniards (at least not right away). I'm about 60% sure what's going to happen within Tawantinsuyu, but I'm not sure what the effects will be on Spain. So I'm asking you at AH.com.

If I understand correctly, the majority of gold and silver from the Spanish colonies in the Americas came from Peru.
