When you think about it, a bet on gold is really a bet that the people in charge don't know what they're doing. Policymakers missed yesterday's financial crisis, so maybe they're missing tomorrow's inflation, too. That, at least, is what a cavalcade of charlatans, cranks, and armchair economists have been shouting for years now, from the penny ads that run on the bottom of websites — did you know that the $5 bill proves the stock market is on the cusp of crashing? — to Glenn Beck infomercials and even hedge fund conferences. Indeed, John Paulson, who made more fortunes than you can count betting against subprime, has been piling into gold for six years now, because he thinks "the consequences of printing money over time will be inflation." They all do. Goldbugs act like the Federal Reserve's public balance sheet is a secret only they have discovered, and that it's only a matter of time until prices explode like they did in the 1970s United States, if not 1920s Germany.
But economists do, for the most part, know what they're doing. Sure, they missed the crash coming in 2008, but that wasn't because they didn't understand how bank runs work. It was because they didn't understand that unregulated lenders had become vulnerable to runs. And the economists who haven't forgotten their history knew that this inflation fear mongering was all wrong too. Specifically, there's a difference between the central bank buying bonds, a.k.a. printing money, when interest rates are zero and when they're not. In the first case, money and short-term bonds both pay the same amount of interest — none — so, as Paul Krugman has explained over and over again, printing one to buy the other won't change anything. Banks won't lend out any new money, and will just sit on it as a store of value instead. That's what happened when interest rates fell to zero in 2000s Japan, and it's what is happening now in the U.S., U.K., Japan, and Europe.
That didn't mean, though, that gold wasn't a good short-term investment. It was. Just not for the reason goldbugs thought. Now, the problem with gold is it doesn't pay any interest or dividends, but it does cost money to store. So you have to pay up in the hope that it will pay off by going up in price. That usually makes it a pretty lousy investment. That calculus changes, though, when you're being paid to borrow—that is, when you're paying a negative real interest rate. But when does that happen? Well, when inflation is high but interest rates aren't quite as high, like in the 1970s, or when inflation is low but interest rates are lower still, like today. And that, as Paul Krugman and Larry Summers argued, is why gold prices were going up so much even though inflation wasn't.
It almost makes you feel bad for the goldbugs, until you remember that some substantial number of them are just trying to scare seniors out of their money. But the ones who aren't really thought the 1970s showed that gold went up when inflation did, so the fact that gold was going up now meant inflation couldn't be far behind. They didn't understand that the price of gold doesn't depend on how much inflation there is, but rather on how much inflation there is relative to interest rates. So now that rates are rising, gold, as you can see below, is falling. Wait a minute, rates are rising? Well, yes. The Federal Reserve hasn't actually raised rates yet, but it has talked about it enough that markets have reacted as if it already did. That's been enough to make real rates positive again.
That sound you hear is goldbugs insisting that this is just a flesh wound. Sure, gold is down a lot, but that makes this is a buying opportunity! Just wait until China starts snatching up gold as an alternative to the dollar. Then prices will shoot back up. That, at least, was the story they told themselves until earlier this week, when China revealed that it hasn't been purchasing nearly as much gold as people had assumed. Not only that, but a big fund dumped its gold in the middle of the night, driving the price down to a 5-year low. That's left the goldbugs most impervious to empirical reality with nothing to say other than that "gold hasn't lost any value, the dollar has just strengthened." Right, and my stocks aren't worth any less, I'd just get less money for them if I sold them.
But don't feel too bad for the goldbugs. The best thing about predicting the apocalypse is you get to try again and again and again.
