Drug addicts and alcoholics can appear normal, even when drugged and boozed to the eyeballs. They can even go to work as long as they are "medicated". Only when drugs and the booze are withdrawn do we see their real state.
We saw this week what happens when financial markets and investors addicted to freshly printed money find out the "drug" may be withdrawn soon.
Stock markets around the globe slumped when US Federal Reserve chairman Ben Bernanke threatened to turn off the money-printing drip by mid-next year. Long-term interest rates rose sharply. Most importantly for New Zealand, even China's new leadership got in on the act, forcing up interest rates to their highest point in a decade. The NZ dollar fell three US cents to its lowest point in a year. Banks started raising fixed mortgage rates. Now we'll see just how sustainable the economic recoveries in the US, China and NZ are.
Will we see yet another false start before a relapse to medicated remission? It depends on just how addicted a swathe of developed economies are to low interest rates. That means consumers and households, which constitute more than 60 per cent of spending in these economies.
That in turn depends on how indebted they are and what is happening to their real incomes. That is the truest measure of their economic health.
