Yet another reason to avoid DCM : http://www.theregister.co.uk/2012/06/26/techradar_data_breach/If you use the same password on other sites as you do on DCM, better change it/them just to err on the side of caution.
Here's what puzzles me: interbank rates are just that, they are rates agreed between the banks themselves. No-one else is involved or has any influence on these rates other than the participating banks.
