I would like to know the answer to the question "Did colonial power Spain benefit from S-America".
I think they didn't. The gold they took away from America only resulted in inflation & the armies to send to America costed them a lot of money.

Moved to History.

AFAIK, the gold they imported into Spain destroyed the home economy, since there's now so much cash going around. In the long run, it was ruinous for the country.

Spain experienced some short term benefit from the silver mines. However their colonial policy was heavily focussed on the exploitation of treasure and not on the devlopment of new cities and trading opportunities. The reliance on the price of silver was dangerous because the more silver they mined the more the prices for it fell, and they needed to mine more and more to keep up their profits in real terms.

In the short term they surely benefitted greatly from their SA colonies. The riches they plundered there made them the most powerful nation in Europe for quite some time.
OTOH, they made their economy dependant on their colonies instead of developing their own infrastructure, which caused them to fall way behind when they lost those colonies; so, in the long run, they perhaps lost more than they gained.

Silver was the currency metal of choice in that empire.

Every year, a Spanish fleet would set off across the Pacific, hanged around in Luzon (the Philippines), bought Chinese goods, and sailed back.

I think they could have done it but they spent too much of the money they "earned" in SA to fight the wars in Europe instead of making infrasturtural investions. That´s why they did not have the boost they could have had.

Well, we are benefitting now at least.

At first yes, it made them even morte powerful. You can see the proof of that on the building of severall spanish cities of the early colonial period(very opulent buildings).

However on the long run they became to dependent on the influx of gold and silver, so they did not develop manufactories and basically imported all goods they needed from France and England, which eventually surpassed Spain (and Portugal) as the leading european powers.

I think Spain didn't benefit too much.

It's like a 19 years old guy wining the lottery. He drops the university and starts having a great life. Very good for some years, but at 30 all the money is gone, he has no job nor the hability to get one.

That's what happened to Spain. The money coming from America destroyed the industry in Spain. No one were producing anything in Spain. They just bought everything to other countries with the gold coming from America. In the XVI and XVII century, being susscesfull in Spain meant being able to life without work. Workers were second class people.

Also, the money was spent in a very unwise manner. It was devoted to fight against non christians all over Europe. Both Charles V and Philippe II were christian fanatics.

Don't you mean non catholics?
