The bankers have shown their hand - they fear deflation more than inflation. Pumping-in cash and cutting rates will keep us going through the economic squalls that they created by the same lax monetary policy. If you believe the monetarists, there will be a price to pay, but as long as this crisis management succeeds, the damage will be insidious rather than cataclysmic: money will slowly rot.
Now that we know the opposition's strategy, what do we do? My guess is, hold cash, wait for further crises of confidence, and buy tangible assets, or assets backed by tangibles, at bargain prices.
That's why I think Buffett and Soros have been so clever in acquiring more rail stock in recent months. Railways are a natural Benjamin Graham choice: mature, income-producing investments. There are big barriers to entry - think of nineteenth-century land speculation and skulduggery, and add-in eco protests, modern politics and the unavailability of coolie labour. Rail has advantages over road, especially as so much freight now is containerised and port-to-city; but from an investor's perspective it is also solidly thing-based.
Other experts are into tangibles also. For example, Marc Faber likes real estate in emerging economies - and possibly in depressed areas of developed countries, and Bill Bonner has farmland in Argentina (the Chinese love beef). And then there's various types of commodity.
I think we'll be back to putting money into things we can understand.
