People see bubbles everywhere now, partly because we've seen some whoppers over the past 15 years, and partly because we now expect to see them caused by quantitative easing. You know, the quantitative easing that created trillions of dollars of inflationary money, even though no one we know has ever seen a penny of it. The term 'bubble' used to mean that an increasing number of investors purchased an asset in anticipation of a short-term increase in price. But now 'bubble' just means that an asset price has gone up, and you think it will soon decline.
Not many people are saying there is a housing bubble right now. That includes the so called experts who didn't foresee the last housing bubble, and didn't foresee the housing recovery that started last year (I called it.). It was all obvious if you were looking at the data. Oddly, most experts in the media don't look at data, instead they just spew ideology.
But over the next 6 months it will become inescapable, even to the 'experts', that house prices are skyrocketing in much of the nation. Since most 'experts' have as little understanding of the US monetary system as they do of data analysis, they will immediately shriek that the Bernanke has created another housing bubble. It fits their habit of blaming the government for everything, and glossing over their inability to accurately predict anything. The experts will demand an end of QE to stop the housing bubble, and their fear mongering will probably be enough to get it - which may be just as well if economic growth and inflation expectations are high by then. They will also demand that the Fed raise short interest rates immediately, but they probably won't get that anytime soon.
But why are house prices going up? First, house prices fell too much during the crash in many places. Second, we pretty much stopped building new houses since 2008 and have since consumed whatever excess there was. Third, employment is slowly recovering and families are still being created in the US, so that creates natural demand for more housing. And finally, large institutional investors have recognized the three preceding reasons and are buying up large numbers of houses in order to rent them out.
But nowhere in my description, or I think in any quantifiable account, or even in anecdotal accounts, are people buying houses for the purpose of re-selling them in the not too distant future. People are actually buying houses to either live in them, or because they want to rent them out for someone else to live in. What a great idea, we use houses as shelter! That doesn't sound like a bubble.
Now it may be that some investors enter the housing recovery too late and pay too much. And it may be that investors create too many rentals and drive the rental rates down to unprofitable levels. And some investors may discover that it is hard to get a good property manager, keep the property maintained affordably, and find good tenants that pay on time and don't rip up the house. But that's just describing the investment and management difficulties of any business. Rental houses aren't the lazy man's way to riches, and some will lose money. But that is a very different proposition than 'flipping' houses.
Likewise, there is no bubble in bonds. A 5-year Treasury yields 0.69%. The only way the bond's value can go up much is if market interest rates fall a lot. But they can't fall far from their very low current rate, unless you think Treasury rates will go negative, or unless you expect severe deflation. But the very people who say that there is a bond bubble are the ones also predicting rampant inflation rather than deflation. Of course you can lose lots of money on bonds if interest rates go up, which isn't unlikely someday since current interest rates can rise much more than they can fall. But that's not the same as a bubble, that's just a natural change in the economy.
So here's what's really amazing to me. The people that see bubbles in bonds and housing rarely see one in gold or bitcoins. But gold and bitcoins have all the obvious characteristics of a bubble: their value is based solely on scarcity rather than operating income, they are purchased for appreciation rather than utilization, and many of the buyers knew nothing about the assets a few years ago (aka 'suckers').
Which brings me to the underlying problem of bubbles. We have seen more bubbles than usual in the past 15 years, but they are correlated rather than caused by low interest rates and lose monetary policy. We have low interest rates mostly because we have more savings than we have investment demand for the savings. The Fed has brought down rates somewhat - BlackRock's fixed income head estimated the Fed lowered the long bond yield by 100 bps with QE, which sounds reasonable to me, but even +100 bps is a low interest rate by historical standards.
Bubbles regularly occurred when economies operated on the gold standard (Tulip mania, South Sea bubble, etc.), so monetary policy isn't what causes a bubble. Though debt financing of a bubble can make the downside much worse. No, a bubble is created by a confluence of excited suckers who think they can make large amounts of money without either working themselves or putting their money to work over the long run. We can always find people like that.
We have seen more large bubbles in the past 15 years because we don't know where to invest our money in a productive enterprise. We have an enormous amount of savings looking for an investment: sovereign wealth funds investing their trade surplus in the US, pensions and retirement funds, massive corporate retained earnings, and the fortunes of very wealthy individuals. Even if our consumer demand were stronger, I'm dubious that our service based domestic economy has a use for that much in savings. All those savings result in low real interest rates, regardless of what the Fed does.
When someone does find a good investment opportunity, a huge pool of savings moves in and provides all the capital that was needed. So the asset price jumps, and that appreciation attracts even more investors who can turn a legitimate investment into a bubble. With the big housing bubble so fresh in investors minds, I really doubt we will see another one so soon (give it another decade). Regardless of the asset class, as investors get more used to bubble behavior, they get ever faster at jumping in and out of bubbles and shorten their cycle.
We either need more legitimate investment opportunities (including possibly infrastructure and education), or we need to turn a lot of the savings into consumption. Significantly increasing bank capital ratios is one way to put idle savings to work, and in return for that investment we get an environment with fewer government bailouts, and the reduced leverage wouldn't fuel future bubbles. Besides, we don't need additional leverage in a savings glut.
Counter intuitively, something else that I think would increase our productive investment is if inflation were quite a bit higher than the Fed's 2% target. When business people are considering investment decisions, they don't really think about it in terms of the inflation adjusted real return (business schools be damned). Right now many safe investments may reasonably yield 3%, But absolutely no one wants to pitch a business investment at a 3% return. It just sounds pathetic. So to hit higher returns investors turn to leverage or bubbles, and sometimes frighteningly both.
But if the underlying inflation rate were 5% and the nominal return was 8%, then that's quite acceptable for an un-leveraged, safe investment. I know the real investment return hasn't changed in these scenarios, and business people should know better - but optics are important, particularly to executives, committees, and shareholders. Note that this increase must be done with inflation, because if the Fed merely raised real interest rates to 5% then the higher cost would crush the amount of credit that borrowers could profitably bear, and cause investment and consumption to plummet.
As long as we trade with nations that buy their currency down in order to export goods to us, the US will tend to have a surplus of savings and a deficit of jobs, no matter how we manage monetary policy and bank leverage. Meanwhile the looming threat of a fractured Euro and floundering China could cause even more capital to flee to the US for safety. So we had better figure out how to put the savings to good use rather than embracing existing bubbles, running from imaginary bubbles, and living in the absurd terror of 3-5% inflation.
