I should emphasize that the uncertainty I'll be speaking about relates to the models, indicators, and data we use to conduct monetary policy, not to what we call "risks" to the economic outlook – that is, possible outcomes around our "base-case" projection. To make my remarks concrete, I'll refer to how we estimate the potential output of the economy.
Even if, for instance, IT services and servers are outsourced, the bank still needs to bear responsibility, in the form of an audit trail for supervisors, for the security and availability of data.
