These risks, believes Nouriel Roubini, are already exacerbating the economic slowdown: equity markets are falling everywhere, leading to negative wealth effects on consumption and capital spending. Roubini explained that the borrowing costs are rising for highly indebted sovereigns, credit rationing is undermining small and medium-size companies, and falling commodity prices are reducing exporting countries’ income. Increasing risk aversion is leading economic agents to adopt a wait-and-see stance that makes the slowdown partly self-fulfilling.
According to Roubini, the situation now is more complicated collated to some crisis in the past. He thinks that, compared to 2008-2009, when policymakers had ample space to act, now monetary and fiscal authorities are running out of policy rabbits to pull out of their hats. Monetary policy is constrained by the proximity to zero interest rates and repeated rounds of quantitative easing. Indeed, economies and markets no longer face liquidity problems, but rather credit and insolvency crises. Meanwhile, unsustainable budget deficits and public debt in most advanced economies have severely limited the scope for further fiscal stimulus.
Nouriel Roubini thinks that using exchange rates to boost net exports is a zero-sum game at a time when private and public deleveraging is suppressing domestic demand in countries that are running current-account deficits and structural issues are having the same effect in surplus countries. After all, a weaker currency and better trade balance in some countries necessarily implies a stronger currency and a weaker trade balance in others.
