Welcome to the Everything Boom, or Maybe the Everything Bubble

In Spain, where there was a debt crisis just two years ago, investors are so eager to buy the government’s bonds that they recently accepted the lowest interest rates since 1789.

In New York, the Art Deco office tower at One Wall Street sold in May for $585 million, only three months after the going wisdom in the real estate industry was that it would sell for more like $466 million, the estimate in one industry tip sheet.

In France, a cable-television company called Numericable was recently able to borrow $11 billion, the largest junk bond deal on record — and despite the risk usually associated with junk bonds, the interest rate was a low 4.875 percent.

Welcome to the Everything Boom — and, quite possibly, the Everything Bubble. Around the world, nearly every asset class is expensive by historical standards. Stocks and bonds; emerging markets and advanced economies; urban office towers and Iowa farmland; you name it, and it is trading at prices that are high by historical standards relative to fundamentals. The inverse of that is relatively low returns for investors.

The phenomenon is rooted in two interrelated forces. Worldwide, more money is piling into savings than businesses believe they can use to make productive investments. At the same time, the world’s major central banks have been on a six-year campaign of holding down interest rates and creating more money from thin air to try to stimulate stronger growth in the wake of the financial crisis.

“We’re in a world where there are very few unambiguously cheap assets,” said Russ Koesterich, chief investment strategist at BlackRock, one of the world’s biggest asset managers, who spends his days scouring the earth for potential opportunities for investors to get a better return relative to the risks they are taking on. “If you ask me to give you the one big bargain out there, I’m not sure there is one.”
