European Central Bank (ECB) president Mario Draghi has said that it's hard to disagree that low interest rates pose risks in the long term.
ECB rates are currently at historic lows, and Draghi has previously said that negative rates were a tool that are ready to go. He followed up by saying that higher rates aren't currently warranted.
Speaking on the Financial Transaction Tax Draghi said that the ECB shares the objectives of the measure, but questioned the operational feasibility of such a tax, and said that the policy could have several undesirable implications for monetary policy.
However, Draghi noted that the ECB is not the fiscal authority, and as such is only concerned with how the measure would impact monetary policy decisions.
