Statement: After the Reserve Bank of India’s adoption of a flexible inflation-targeting framework from August 2016, the rules of monetary policy have changed in India, with the central bank becoming even more focused on anchoring inflation and inflation expectations than ever before.

Assumptions:

I. There was a perceived need or rationale for the RBI to shift its monetary policy framework in 2016, suggesting that the previous rules may have been inadequate.

II. Monetary policy can be adjusted and adapted to changing economic conditions and goals, such as inflation targeting.

Both of the assumptions are necessary for the statement to make sense:

Assumption I talks about the RBI's adoption of a flexible inflation-targeting framework in 2016 - the implication here is that there was a reason or need for this shift, indicating that the previous rules or framework may not have been sufficient in achieving the central bank's objectives.

Assumption II is also necessary because the statement discusses how the rules of monetary policy have changed, indicating that monetary policy can indeed be adjusted and adapted to meet different economic conditions and goals. Without this assumption, the idea of a shift in monetary policy would not be meaningful, as it would imply that policy cannot change to respond to evolving circumstances.
