I wrote a couple of posts on this topic. Warren Buffet says there is "potential" for high inflation in the future. Past experience indicates that gold and commodities are a hit-or-miss in terms of an inflation hedge. Equities are an effective long-term hedge. Real estate & commodities might perform well. The only clear loser will be traditional government bonds that currently yield less than 4%. Real return bonds are the almost perfect hedge against inflation but the real yields are typically low.
