Today will see the release of economic data that includes the Eurozone unemployment rate, German factory orders, US mortgage applications and US employment data. The Eurozone unemployment rate is expected to remain below record high levels, while retail sales for the region are predicted to register a rise. Craig Erlam, Alpari Market Analyst, said: "Things have improved significantly in the Eurozone in the last six months, with a number of countries, and the region as a whole climbing out of recession, confidence in the region growing as seen by the substantial improvement in the PMI readings, and two countries, Ireland and Spain, exiting their respective bailout programs. "I wouldn't say things are looking rosy for the currency block, by any stretch of the imagination, but compared to this time last year, they're looking much better [...] The [unemployment] rate is expected to remain at 12.1% in November, but as long as we don't see a return to record high levels, I think this will be viewed as a positive result." Over in the US later today, the ADP employment change figure will be released, which Erlam explained "should give us some insight into whether the improvement in the labour market seen in October and November continued into the end of the year, and whether the Fed was therefore right to reduce its bond buying programme in December".In other news, a top City regulator has insisted that the appointment of Paul Flowers was not a mistake after facing tough questioning over his approval of the appointment of the now disgraced former Co-operative Bank Chairman.
