Official measures of inflation are widely used by inflation targeting central banks to determine monetary policies. Inflation measurements therefore dictate these policies.

When inflation is not measured right, for example if it is under estimated, this may prompt central bank to lower interest rates and pump up money supply ! Such action can lead to a failure of the banker function damaging the structural core of the economy.

Yes ! Inflation measurement is policy itself. Dark inflation makes GDP appear larger, disrupts money supply and leads to the failure of banker function.
