Looks like the SNB has been at it again:
The Swiss franc weakened as much as 0.4 per cent on Tuesday, the most since February 5, according to Bloomberg. There was no comment from the SNB on whether it was down to central bank intervention, but the move seemed in keeping with previous spontaneous moves of the euro versus the franc, which were put down to official intervention.
