HB did indeed point out that the times that gold would be needed most are precisely those times with significant political, financial or social upheaval. It isn't only about "Mad Max" scenarios, though. Counterparty risk can occur on much smaller scales. Take MF Global for example. I still worry that there are bad precedents being set in the lack of legal consequences for clearly illegal financial maneuvers.Ad Orientem wrote: Setting aside the arguments for gold as an inflation hedge the question seems to be why physical? Physical gold is the financial equivalent to catastrophic health insurance...
There's also the expense ratios of ETFs. Aside from the safe deposit box rental, physical gold incurs no expenses. Over long periods of time, expense ratios will make a gold investment wither away, as it (uniquely) does not pay interest or dividends. Inevitably, this must produce a gradually increasing tracking error. I wonder if it hasn't shown up yet only because the ETFs haven't been around long enough, and have yet to experience a serious downturn in gold prices.
Of course, this comparison only applies to taxable accounts. Despite the drawbacks, ETFs make perfect sense in a tax-advantaged account where physical gold isn't really an option.
