Gold is the ultimate antifragile asset. Unlike fragile assets such as equity indices, antifragile assets react positively to stress. Does it make sense to constantly hold gold in a diversified investment portfolio? ‘No’, is the answer. 50% of the time, when currencies act as stores of value, gold is a useless asset. However, the other 50% of the time, when currencies are debased, gold is a vital asset, insofar as it is the centre of pricing of all other financial assets. This paper will take the former 50% of the time to be ‘Wicksellian times’, while the latter 50% to be ‘Keynesian times’. World economies re-entered ‘Keynesian times’ on January 31st, 2019, following the monetary policy reversal of the FED. Statistics on portfolio allocation advocate a switch in these periods: from bonds to gold, from developed economy equities to emerging equities, and from cash to real estate. Gold, however, is not antifragile by nature; it has only turned antifragile since the end of the Gold Standard in 1971 because of its pricing in currencies. And currencies are fragile assets
