The Riksbank is now fully aligned with the Yellen Fed in Washington, which argues that raising rates to stop asset bubbles merely destroys jobs for little useful purpose. Both are pitted against the Bank for International Settlements. The BIS says radical monetary stimulus may help invidual countries but only by displacing the problem onto others, leading to a “Pareto sub-optimal” for the world as a whole. It warns that speculative excess is reaching pre-Lehman levels, and calls on global central banks to take pre-emptive action before the bubbles becomes unmanageable.
