I think investors are worried about the wrong kind of crisis in China.

Worry seems to focus on the possibility of an asset bubble and the chance that it will burst sometime in the next two to three months.

I’m more concerned about a slide into a crisis that will be an extension of the Great Recession. That slide could begin, I estimate, sometime in the next 12 to 18 months.

I understand the worry about the possibility of an asset bubble in China. After all, we’ve just been through two horrible asset bubbles — and busts — in the U.S. and global financial markets. And a Chinese bubble is a distinct possibility, one that should certainly figure into your investing strategy.

But China’s economy and political system are so different from ours in the U.S. and those in the rest of the developed world — and its relationship to the global financial market so unique — that I don’t think we’re headed toward any kind of replay of March 2000 or October 2007.

A bigger worry is a long-term slide into a lower-growth or no-growth world in which nations strive to beggar their neighbors and all portfolios slump. As crises go, it’s very different but ultimately just as painful for investors as the asset bubbles that draw all our attention now.

To paraphrase Leo Tolstoy in “Anna Karenina“: Happy bull markets are all alike; every unhappy bear market is unhappy in its own way.
