Financial crises average once every 7 years: one due therefore?

Guardian: “Financial crises come round every seven years on average. There was the stock market crash of 1987, the emerging market meltdown in the mid-1990s, the popping of the dotcom bubble in 2001 and the collapse of Lehman Brothers in 2008. If history is any guide, the next crisis should be coming along some time soon.”
“The fact that the financial markets are betting on global recovery becoming more firmly established over the next two years doesn’t really signify much. Investors refused to heed warnings that tech stocks were wildly over-valued around the turn of the millennium. Ben Bernanke rubbished the idea that the US sub-prime mortgage market was an accident waiting to happen, and refused to countenance the idea that a problem in American real estate might have global ramifications.
So let’s conduct a thought experiment. Assume that the IMF, the World Bank and the financial markets are all wrong when they say the US is now set for a period of robust growth, that Europe is on the mend and that China can make the transition to a less centrally planned economy without a hard landing.
….In those circumstances, three questions need to be asked. The first is where the crisis is likely to originate, and here the smart money is on the emerging markets.
….A renewed bout of turbulence would start with interest rates already at historically low levels, budget deficits high and central banks stuffed full of the bonds they have bought in their quantitative easing programmes. Conventional monetary policy is pretty much maxed out, and there seems little appetite for a co-ordinated fiscal expansion, so the choice would be unconventional monetary policy in the form either of more QE or helicopter drops of cash.
….All the ingredients are there for social unrest, which is why the ILO’s Guy Ryder is right to call on businesses to use rising profits for productive investment rather than share buy-backs.”
