I just finished reading
The Oil Factor by Stephen and Donna Leeb, an investing book centered around peak oil. Let me sum up their take:
-High oil prices are by nature inflationary
-During the last oil crisis, eventually, the US gov't decided to curb inflation by raising interest rates. That worked
-In this case, they can't do that because of the massive US debt. Raising rates too quickly could send the economy into a tail spin. The Fed will at most gingerly, slowly raise rates, backing off at any sign of trouble. Not enough to stop inflation
-Productivity gains have been historically overrated and likely can't reverse inflation in the years ahead
-In fact, because so much debt is leveraged directly to housing prices, the Fed may use negative real rates to keep housing prices up. Negative real rates mean that interest is so low, that you make money by buying real assets (like homes and gold) and holding onto them. Ex: you take a $100,000 loan and by a home. In 20 years you have to pay $110,000 back, but the home has become $130,000 by inflation alone! (**I was suprised the authors didn't consider that oil highs may make suburbia worthless...)
-So, inflation will probably be high, maybe even ridiculously high because the governemnt will use negative real rates in a desperate ploy to keep home prices from falling and ruining consumers
-HOWEVER, if oil prices rise very fast, that could criple the economy, which would cause deflation
-Therefore, for now start with an inflationary holdings (e.g. stocks that bet on gold/energy/defence) and hold a few deflation plays (bonds, zero coupon bond funds, etc.) as a back-up. If oil rises 80% in price over a year, switch almost entirely into deflation plays because the economy will probably tank. Wait until the year-over-year rise in oil prices drops to 20%, and then it's safe to go back into inflation mode
-Inflationary times are very unforgiving investment climates (for reasons I won't summarize - takes awhile), and will require skilled investing. Especially since the economy could go deflationary at any time
So that was the take of the only peak-oil-specific investing book I know of. Probably riotous inflation, with sharp deflationary periods when the economy tanks or the Fed mis-steps.
Of course, the Fed could raise rates too high, crash the housing market and tons of debt, and criple the economy. They could do that by accident, or (Machivelian/conspiracy version) intentionally bankrupt people to make everyone reduce their energy use, or become poor and therefore desparete slave labour
