Minerva and Griphook weren't surprised by the idea of taking raw gold and turning into coins. Presumably this happens sometimes; it's not the case that all the Galleons in the world were first minted thousands of years ago. So how did the gold in the wizard economy get there in the first place? And what is the mechanism that prevents it now but didn't prevent it then?

Are all wizards in the world unaware that Muggles possess gold at all? Surely not; Muggles probably own much more gold, and operate many more gold mines, than wizards do. If wizards ever went looking for un-mined gold, they'd encounter Muggle competition.

Wizards have an apparently trivial method of acquiring gold: Apparate into a bank vault, fill your Bag of Holding, Apparate away to Gringotts. It's doable by most wizards, carries no real risk, is unnoticeable by the bank, untraceable when they do notice the gold is missing, and the other wizards and goblins probably don't care if some Muggles were robbed by an unknown wizard.

Serious problem: http://en.wikipedia.org/wiki/List_of_countries_by_gold_production = 2700 metric tons annually produced today. If there are one million wizards in the world, it takes 1000 tons of gold to have one kilogram of gold / 200 Galleons per person (~$50K at today's prices). Or they have to produce a ton a year for a thousand years. How much gold was in pre-industrial e.g. Aztec civilization?

That's a good point. I also add that Wikipedia says that:

A total of 174,100 tonnes of gold have been mined in human history, according to GFMS as of 2012.

But still, if just a few wizards stole appreciable fractions of the Muggle gold vaults, they would be individually very rich. The same 1000 tons of gold would be a (ETA fixed calculation) 200 million Galleon fortune if owned by one wizard. Therefore, the question is how much gold is concentrated in one place (already mined) and available for stealing.

Wikipedia provides a list of officially reported gold holdings by country. The top few are: US, 8133 tons; Germany, 3391 tons; IMF, 2814 tons; Italy, 2451 tons; France, 2435 tons.

But where is the gold physically kept? Well, Wikipedia says that Fort Knox holds 4578 tons of gold. In any case, a wizard could Apparate to people, ask them where most of the gold is (Legilimency/Veritaserum/Imperius), Memory-Charm to erase the few minutes of the encounter, and Apparate away. If the person doesn't know where the gold is, they can tell you who does know. Start with someone like a bank CEO, unlikely to have magical protection (unlike heads of state), and work your way on - in a day or two you'll find the gold.

How do we know this hasn't actually happened? The gold in the bank vaults may not be actually there. But the wizarding economy doesn't have a known history of occasional sudden billionaires. Lucius probably never even heard about fortunes of more than a few million Galleons.

There's another big pile of gold, about 7,000 tonnes, in the New York Fed--that's actually where a lot of foreign countries keep a large fraction of their gold supply. It's open to tourists and you can walk in and look at the big stacks of gold bars. It does have fairly impressive security, but that security could plausibly be defeated by a reasonably competent wizard.

More to the point, whatever security Muggle vaults had 100 or 200 years ago definitely wouldn't have stood up to wizards. (Their powers wane by the year, while ours wax.) Since all the Muggle gold didn't vanish long ago, there must be a different explanation than Muggle vault security.

I think that a lot of the Hogwarts Founders and Merlin stuff was actually setting things up so stuff like this wouldn't happen.

Comment author: Alsadius 17 August 2013 09:47:20PM 1 point [-]

Possibly, but why couldn't it have happened prior? There was plenty of gold around in the ancient world, and not enough of it got stolen. Nor is enough sitting in the wizarding economy.

The statute of secrecy also didn't exist back then.

What are the relevant implications of that? I'm not coming up with any.

  • Muggle society could hire wizards to punish thieves.

  • Wizards would know more muggles personally.

  • Maybe there really were fortunes made in those days, and it was covered up on our end. (Small fortunes, because muggles hadn't had time to mine as much gold?)

Hypothesis: Aurors simply put alarm spells in large repositories of gold.

(This may not be widely known, because everyone who realises that muggles can be stolen from does so and is jailed.)

Comment author: DanArmak 21 August 2013 08:55:19PM 1 point [-]

It doesn't matter that much if some wannabe thieves get caught. Only one thief needs to succeed per vault per century to make all the Muggle gold disappear. An alarm isn't enough against several wizards who take the time to prepare a raid. Only a round the clock guard would be enough. If Aurors guard all the big Muggle gold vaults (or that the goblins or their dragons do), that might be a sufficient deterrent.

What isn't clear is why they would install alarms or provide guards, instead of just taking the gold themselves.

Well, if it's an unusual idea to start with, and hard to hide - I mean, if you don't get suddenly and suspiciously rich, what's the point? - and most people get filtered out because their brilliant and original plan was actually anticipated (remember, the whole point of stealing from muggles is that they wont have magical protections) ... I can see it being pretty much a non-starter.

Also, is that actually true? I mean, there's only so much gold per vault, only so much time for this to have happened in, and so on. Heck, would we even still use vaults if "police baffled by fort knox raid" showed up on the news every so often, to the point that the majority of Earth's gold was lost that way?

There's enough gold per value to make a successful thief the richest wizard in the world. And there have been big gold vaults for many centuries, with royal treasuries preceding them. And yet there hasn't been even one case in Muggle history of all the gold disappearing from a vault without explanation.

A thief could still succeed once. That we still use vaults indicates a thief has never succeeded. There's still something to explain.

Funnily enough, it occurred to me that I have no idea if any such cases* have* occurred. I still don't, because all the top Google hits seem to be conspiracy theories or something about how various gold reserves are totally empty. (Maybe a coverup would actually be possible with magic? Hmm ... Fort Knox hasn't been audited in 60 years, supposedly, so who knows?)

But honestly, who cares if you're the "richest wizard in the world" if you're in jail and your "wealth" is an unspendable stolen asset (remember, raw gold needs to be converted into coins)?

A thief could still succeed once.

Yeah, I just meant that muggles wouldn't actually lose all the gold. It's a moot point, since clearly this hasn't happened either way.

A little digging suggests less than a thousand tons. Most of the metal wealth extracted by the Spanish empire was in the form of silver, not gold. The spanish were able to mine about a ton a year from hispanola for some unknown period, and the inca paid a ransom of 24 tons for their king.
