Growing evidence of a severe global recession is sure to provoke more aggressive monetary policies from central banks. They had hoped to have the leeway to cut interest rates significantly after normalising them. That hasn’t happened. Consequently, as the recession intensifies central banks will see no alternative to deeper negative nominal rates to keep their governments and banks afloat through a combination of eliminating borrowing costs and inflating bond prices. It will be the last throw of the fiat-money dice and, if pursued, will ultimately end in the death of them. Gold and bitcoin prices are now beginning to detect deeper negative rates and the adverse consequences for fiat currencies.
