With this general framework in mind, here’s how I’ve been thinking about the global macro outlook for a while: It is driven by the interaction among what I call the “three gluts”: the savings glut, the oil glut and the money glut. While the global savings glut is likely the main secular force behind the global environment of low growth, lowflation and low interest rates, both the oil and the money glut should help lift demand growth, inflation and thus interest rates from their current depressed levels over the cyclical horizon. ... Why is it, to simplify further, that everybody wants to save more but nobody wants to invest? ... The oil glut helps to mitigate the depressing impact of the savings glut on consumer demand by shifting income from oil producers, who have a high propensity to save, to consumers, who typically spend most of their income. ... We expect more monetary easing to come, particularly in China and in many commodity-producing countries, so the global money glut, which is already increasing due to heavyweights like the European Central Bank and the Bank of Japan executing their asset purchase programs, will swell further.
Famous German soccer coach Sepp Herberger once said, “After the match is before the match.” The same can be said for financial markets: After the crisis is before the crisis. The complication, of course, is that while soccer players usually know exactly when the next match will kick off, the timing of the next crisis is always uncertain for financial players. All we know is that, eventually, there will be another one. ... What’s perhaps less obvious is that the global savings glut also helps to explain the occurrence of financial bubbles and subsequent crises of the past few decades. ... the global savings glut plays an important role in explaining this evidence. How? Excess savings not only pushed down r* and actual interest rates but also drove up asset prices and caused serial asset bubbles in equities, emerging markets, housing, credit, eurozone peripheral bonds and commodities. Whenever a bubble burst, it sparked financial distress and crisis. ... there is a feedback loop between financial crises and the savings glut. This is because a financial crisis and the related destruction of wealth leads to even higher desired saving (or deleveraging), and because the depressing impact on growth reduces investment and thus the demand for savings. ... now that exhaustion has set in almost everywhere for many unconventional policy tools, such as quantitative easing, there is a significant risk that central banks may not be able to deal effectively with the next crisis. ... It’s likely the only viable way out would be a joint effort by the major countries to raise public spending on infrastructure, education, and more in order to absorb excess savings and raise r*.
