True, if there is inflation, it is easier to do the budgeting, to plan, to breathe, etc. because if your prices are changing all the time and your exchange rate is unstable, you will never really be comparable with the rest of the world, as today’s calculation will simply not apply tomorrow, let alone the day after.
This is what the ECB has done in the past when it took “nonstandard” measures. Put differently, I do not see a dependence, or necessary sequence, between the level or path of policy rates and the possible adoption of “non-standard” measures aimed at improving the functioning of markets and preserving the stability of the banking system.
