“The least thing upset him on the links. He missed short putts because of the uproar of the butterflies in the adjoining meadows. ” PG Wodehouse Financial contagion is a phrase employed by those who try to explain a fall in an asset price that they didn’t see coming. If it means anything, which is not certain, it describes the fallout from the volatility that results when any market falls because people are forced sellers. This is prone to cause panic which in turn means that the attraction of holding cash rises. Given that no one likes to sell a falling asset (a psychologically taxing experience) people prefer to raise money by selling things that haven’t fallen in price but look potentially vulnerable (especially if viewed with a newly sceptical eye). As the quote from PG Wodehouse shows, when things go wrong we tend to cast around for something to blame. Bad things happen to relatively overpriced assets and the nature of the event that triggers their decline is really of no consequence. The need to explain what happened is driven by a reluctance to take responsibility for a poor investment decision. Hence we are allegedly the victim of the devaluation of a currency, the collapse of an obscure foreign bank, the failure of a harvest or the uproar of beating butterflies’ wings. In reality, contagion is not a hidden threat but a constant reality that we should never forget. All assets are in competition all the time, subject to perceived risk and liquidity. All asset values are relative to each other. The most crass mistake that financial analysts make (and I certainly write from experience) is to compare the price of an asset with its own history and to declare that this proves it to be cheap or expensive. Here are ten assets in which you, if your assets and liabilities are UK based, might conceivably invest, ranging from cash (the most liquid) to commercial property arguably the least liquid).
