The dollar ended the year on a strong note, adding three quarters of a cent against sterling and losing only a dozen or so ticks to the euro. With only three working days to separate Christmas and New Year, and with the usual shortage of tradable economic data at this time of year, investors found little to inspire them. Their decisions were driven more by the desire to tidy up positions for year-end, and to realise profits (or losses), than they were by underlying sentiment. 

It has been a good year for the dollar, which has been 2015's joint top performer among the major currencies with gains of 5% against sterling and 10% against the euro. (The Swiss franc shared the honours.) In the last month it has gone off the boil following the Fed's anticlimactic rate increase but more than one analyst is looking for parity with the euro in the coming year.
