Aaron-Micael Beydoun has estimated the depletion of Abu Dhabi's oil reserves in 93 years in a course on investment management at Harvard University. Managing the USD 620 Billion of the Emirate's sovereign wealth vis-à-vis the Abu Dhabi Investment Authority, ADIA, he has proposed the following: Although an optimization of financial assets has established the portfolio strategic asset allocation, this ignores that underlying commodity asset i.e. oil, that forms the majority of client’s implied existing portfolio. Since the oil that forms the bulk of implied national wealth is highly volatile, then traditional portfolio investment risk management that only includes invested financial assets may not properly account for total wealth risk. Therefore, so as to properly account for national wealth risk, we recommend a strategic asset allocation that broadens the asset base to include the non-monetized commodity asset i.e. oil so as to properly account for national wealth risk.
