@johnefrancis In the past, currencies were fixed and interest rates influenced by government. Failure to act to curb inflation lead to runaway inflation such as in the 1970s. In 1980, Bank of Canada got totally independent setting of rates. (so politicians could no longer be blamed for high interest rates).
Currencies were also made free floating to adapt to balance of payments.
Bank of .CA doesn't just look at inflation sats. They also look at value of CAD and many other metrics.
