Save Us, Ben Bernanke, You're Our Only Hope

How Star Wars tells you everything you need to know about the miserable U.S. recovery and the Federal Reserve that has failed to improve it.
This may not be our darkest hour, but the disappointing May jobs report showed the U.S. economy once again slowing towards stall speed. It's not just the anemic 69,000 jobs the economy added last month. More disconcerting were the sharp downward revisions to previous months. It looks like we could be in for an unwelcome rerun of the summer doldrums we have gotten to know all too well in 2010 and 2011.
Markets have a bad feeling about this. It isn't just about the deteriorating U.S. outlook. Europe and China are turning to the dark side of growth too. The euro is continuing its game of SchrÃ¶dinger's currency: At any moment it is both saved and doomed. Right now, it's looking more and more doomed. Then there's the slowdown in China -- along with India and Brazil. These economies powered global growth during the dark days of 2008 and 2009, but seem certifiably wobbly now.
The Fed is our last hope -- and there isn't another. Republicans in Congress continue to block further fiscal stimulus, despite historically low borrowing costs and a clear need for better infrastructure. So that leaves Ben Bernanke & Co. as the last and only line of defense. But with short-term interest rates at zero, how much more can the Fed do? What would more quantitative easing accomplish -- and what does that even mean?
In a galaxy far, far away, there wouldn't be any question about whether the Fed could kickstart more growth. That galaxy is called Israel, or Sweden, or Switzerland. Even with zero interest rates, a central bank can increase growth thanks to three things: expectations, expectations, and expectations. Oh, and expectations. But we're getting ahead of ourselves. Let's step back and first consider why critics say the Fed is "out of ammo". Then, we'll explain why that's wrong -- by referring to the ur-text of monetary policy: the script of Star Wars. Really.
IT'S A (LIQUIDITY) TRAP!
A long time ago -- in 2008, to be exact -- monetary policy seemed simple. Central banks raised short-term interest rates when the economy got too hot, and lowered them when it got too cool. The way they did this was simple too. They sold short-term bonds to banks when they wanted to raise rates, and bought short-term bonds from banks when they wanted to lower rates. Central banks got so good at this that the business cycle seemed tamed. Unemployment was low, inflation was lower, and recessions were rare. Economists gave themselves a pat on the back for this self-proclaimed Great Moderation.
That was before the dark times. Before Lehman. Then this tidy little world came crashing down. The shock from the financial crisis was so big that even a zero percent interest rate wasn't enough to turn the economy around. It still isn't. The Fed looks stuck. It can't push nominal rates below zero. What more can it do?
The Fed has tried a new strategy. It has bought long-term bonds. In other words, bonds that still have nonzero interest rates. The idea behind this unconventional easing is the same as for conventional easing: To push up growth by pushing down interest rates -- just on different bonds. These different bonds have mostly been longer-dated Treasures, as well as mortgage-backed securities and agency debt from Fannie Mae and Freddie Mac. Taken together, this rather misunderstood bond-buying goes by the rather unfortunate name of "quantitative easing".
From a certain point of view, quantitative easing is money-printing. From another, it's just an asset swap. Let's think about what this means. Or rather, let's think about where the money for quantitative easing comes from. The magic of central of banking is that the money comes from nowhere. Or whatever the digital equivalent of nowhere is. Remember: Each bank holds a reserve account with the Fed that must meet a certain minimum balance. When the Fed buys longer-dated Treasuries from a bank, it simply creates money and credits the bank's reserve account with this newly-created money. Banks usually only keep the minimum amount in their reserve accounts -- until now, that is. The chart below shows how so-called excess reserves have grown since 2008.
Lots of people don't like this. They worry that this increasing pile of reserves will mean increasing inflation when banks eventually lend them out. Or that this is really just another backdoor bank bailout. Or that this shows that quantitative easing doesn't work.
Let's consider these in turn. First, the Fed has a number of tools to prevent excess reserves from being lent out too quickly. It's actually using one right now, although it really shouldn't be. It pays interest on these reserves. That's right: It pays banks not to lend. So relax, Zimbabwe is not in our future. Second, the Fed doesn't give banks this money for free. The banks give up bonds in return. It's swapping one asset for another. And third, just because so many reserves aren't lent out doesn't mean that quantitative easing accomplishes nothing. If nothing else, it signals that the Fed will not passively watch inflation fall too low. That message matters.
THESE AREN'T THE RATES YOU'RE LOOKING FOR
"These aren't the droids you're looking for." That's what Obi-Wan Kenobi famously tells a trio of less-than-with-it baddies in Star Wars when -- spoiler alert! -- they actually were the droids they were looking for. But thanks to the Force, Kenobi convinces them otherwise. That's a Jedi mind trick -- and it's a pretty decent model for how central banks can manipulate expectations. Thanks to the printing press, the Fed can create a self-fulfilling reality. Even with interest rates at zero.
Central banks have a strong influence on market expectations. Actually, they have as strong an influence as they want to have. Sometimes they use quantitative easing to communicate what they want. Sometimes they use their words. And that's where monetary policy basically becomes a Jedi mind trick.
The true nature of central banking isn't about interest rates. It's about making and keeping promises. And that brings me to a confession. I lied earlier. Central banks don't really buy or sell short-term bonds when they lower or raise short-term interest rates. They don't need to. The market takes care of it. If the Fed announces a target and markets believe the Fed is serious about hitting that target, the Fed doesn't need to do much else. Markets don't want to bet against someone who can conjure up an infinite amount of money -- so they go along with the Fed.
Don't underestimate the power of expectations. It might sound a like a hokey religion, but it's not. Consider Switzerland. Thanks to the euro's endless flirtation with financial oblivion, investors have piled into the Swiss franc as a safe haven. That sounds good, but a massively overvalued currency is not good. It pushes inflation down to dangerously low levels, and makes exports uncompetitive. So the Swiss National Bank (SNB) has responded by devaluing its currency -- setting a ceiling on its value at 1.2 Swiss francs to 1 euro. In other words, the SNB has promised to print money until its money is worth what it wants it to be worth. It's quantitative easing with a target. And, as Evan Soltas pointed out, the beauty of this target is that the SNB hasn't even had to print money lately, because markets believe it now. Markets have moved the exchange rate to where the SNB wants it.
I FIND YOUR LACK OF A TARGET DISTURBING
I've seen a lot of strange stuff, but nothing quite as strange as the Fed's reluctance to declare a target recently. Rather than announce a target, the Fed announces how much quantitative easing it will do. This is planning for failure. Quantitative easing without a target is more quantitative and less easing. Without an open-ended commitment that shocks expectations, the Fed has to buy more bonds to get less of a result. It's the opposite of what the SNB has done.
Many economists have labored to bring us this knowledge -- including a professor named Ben Bernanke -- and yet the Fed mostly ignores it. I say mostly, because the Fed has said that it expects to keep short-term interest rates near zero through late 2014. But this sounds more radical than it is in reality. It's not a credible promise because it's not even a promise. It's what the Fed expects will happen. So what would be a good way to shift expectations? Let's start with what isn't a good way.
Interest rates can deceive you. Don't trust them. Because most people think the point of quantitative easing is to push down long-term interest rates, they think that any time long-term interest rates fall that it's a form of "stealth quantitative easing". Not so. Consider the chart below from Bloomberg that shows one-year inflation expectations.
Inflation expectations have jumped whenever the Fed has eased. That's not surprising. That's the point of Fed easing. What might be surprising is that sometimes long-term interest rates have fallen when inflation expectations have fallen. In other words, targeting interest rates alone can be misleading. A far better target would be the variable that the Fed ultimately cares about: the total size of the economy. Unfortunately, that kind of regime change is too radical for the Fed now. A second-best policy would be targeting the second-best variables: inflation and unemployment. Chicago Fed president Charles Evans has proposed such a rule, saying the Fed should commit to keeping rates at zero as long as core inflation is below 3 percent or unemployment is above 7 percent. Even better would be to promise to keep doing quantitative easing until the economy hits one of those targets.
EASE OR EASE NOT: THERE IS NO TRY.
The ability to manipulate interest rates is insignificant next to the power of expectations. The latter is never out of ammo, because the Fed can always promise to turn on the printing press and buy stuff until people get the message. It's not magic, but it's the closet thing we have to it. The only reason the Fed has failed so far is that it hasn't been determined to succeed. It's tentatively tried things instead. Switzerland shows that there is another path.
Use the force, Ben. Use the force of inflation expectations.
