Data released by the European Central Bank show that real M1 deposits in Portugal have fallen at an annualised rate of 21pc over the past six months, buckling violently in September.
"Portugal appears to have entered a Grecian vortex and monetary trends have deteriorated sharply in Spain, with a decline of 8.4pc," said Simon Ward, from Henderson Global Investors. Mr Ward said the ECB must cut interest rates "immediately" and launch a full-scale blitz of quantitative easing of up to 10pc of eurozone GDP.
