The European Central Bank (ECB) has reportedly begun to consider evening out the "corridor" between the ECB's three interest rates, as the bank moves away from its policy of cheap money and towards a situation where banks must borrow from the central bank. The move, which was discussed at length during a policy meeting last week, would be achieved by making the spreads between the rates more equal. However, the policy was parked for now to avoid blurring the ECB's policy message.
