I am broadly in agreement with this explanation. However, Wolf goes further, suggesting that the savers need to reduce their ‘chronically high’ savings rates so that they no longer run large current account surpluses. The recent research completed under the IEA Empowerment Through Savings programme provides an alternative view.
Germany and Japan are both characterised by old and ageing populations. China has a young but rapidly ageing population (see my previous blog post). It therefore seems highly appropriate for these countries to have high savings rates.
It is true that the UK and USA, for example, have younger populations than Germany and Japan. However, they still have ageing populations. Yet gross national savings rates in both countries are approximately 13% of GDP (compared with 27% and 25% in Japan and Germany respectively (IMF data)). The demographics therefore suggest that it is the USA and UK that have the serious problem – chronically low savings rates.
What might happen if the spenders’ savings were in line with their demographic situation? They would have a lower propensity to borrow and spend, so would have a lower demand for the savers’ capital. The savers would still export capital to the spenders, due to the age differential between the populations, but in far smaller quantities. Saving countries would therefore export more capital to younger countries, in regions such as South Asia, the Middle East and South America. Local investments would also be relatively more attractive, as would increased consumption.
Faced with the ‘credit crunch’, the mantra of most economists and politicians has been to encourage consumers and companies to borrow and spend. And if they stop spending, governments are acting as spenders of last resort.
This is akin to giving a heroin addict more heroin to stop the pain of withdrawal – it might stop the immediate pain but as a treatment it’s totally self defeating. The real problem is that certain economies, notably the UK and USA, are structured in such a way that they are heavily reliant on ever increasing borrowing backed by over-inflated asset values – when this stops, growth and employment collapse. It is this that has to change.
