Why Monetary Policy Independence Is Vital for Sustainable Growth

Monetary policy independence can be described as the freedom to set interest rates and regulate liquidity conditions independently of the fiscal stance, with a focus on ensuring price stability. After a long period of fiscal dominance in India, monetary policy has enjoyed greater independence, particularly since the establishment of the Monetary Policy Committee.

Recent pressures on the rupee have prompted calls for the MPC to support the currency by raising the repo rate. However, under the statutory flexible inflation targeting (FIT) framework, the MPC's mandate is to maintain price stability while keeping growth in view. It cannot raise the repo rate solely to support the rupee unless currency weakness poses a serious inflationary risk. The MPC's recent decision to hold rates reflects this mandate.

Contrarians, citing the impossible trinity, argue that the MPC should prioritise the rupee and capital flows even at the cost of policy independence. Others favour allowing the rupee to weaken while preserving monetary autonomy. The MPC has instead stayed aligned with its statutory objective of price stability.

In her recent piece, Ashima Goyal argued that the FIT regime provides flexibility to combine policy tools, allowing policymakers to move beyond the binary choice between defending the rupee and preserving monetary independence. By combining macroprudential measures with a managed float, policymakers can limit exchange rate volatility, keep the capital account broadly open and still retain substantial monetary policy independence. Rather than eliminating the trilemma, this approach allows policy to operate at an interior point. 

Monetary policy independence matters not only because of the MPC's statutory mandate but also because it enables better policy coordination, which is essential for macroeconomic stability and sustained economic growth.

Policy Coordination
Greater alignment between fiscal and monetary policy is essential to achieve optimal macroeconomic outcomes, with output close to potential and inflation within the MPC's tolerance band. Without coordination, one policy can offset the other, reducing overall effectiveness. For instance, expansionary fiscal policy without monetary accommodation can crowd out private investment. Likewise, contractionary monetary policy without fiscal restraint pushes up interest rates further, weighing on growth.

To prevent interest rates from settling at undesirable levels, a shift in one policy stance should be matched by an appropriate adjustment in the other. For stable and predictable outcomes, the conventional view, reflected in Leeper's active-passive taxonomy, is that when monetary policy is active, fiscal policy should be passive, and vice versa. An active policy determines the price level, while a passive policy focuses on maintaining fiscal sustainability.

Following the adoption of the FIT regime, interest rates have become more responsive to inflation (Alex, 2025). In this framework, an active monetary policy generally delivers better coordination outcomes than an active fiscal policy. Put simply, independent monetary policy makes effective policy coordination easier.

An expansionary fiscal policy boosts output but also creates demand-driven inflationary pressures. The MPC responds by tightening monetary conditions to keep inflation expectations anchored. In a developing economy such as India, where backward-looking expectations remain significant, a more than proportionate tightening may be required because of the greater sensitivity of interest rates to inflation.

With an active and independent monetary policy, fiscal authorities need only make modest adjustments to spending and taxation in response to changes in monetary conditions. This avoids the amplification that occurs when an active fiscal shock requires an even stronger monetary response, making policy coordination easier to sustain.

Fiscal Discipline
Monetary policy independence also depends on the fiscal stance. In the decades after Independence, the government prioritised economic growth, with price stability taking a back seat. The RBI financed government deficits, leading to rapid expansion in reserve money and higher inflation. Following the Liberalisation, Privatisation and Globalisation reforms in 1991, the RBI and the Government of India ended ad hoc deficit monetisation in 1997, while the Fiscal Responsibility and Budget Management (FRBM) Act strengthened fiscal discipline.

The establishment of the MPC and the adoption of the FIT regime, however, marked the decisive shift towards greater monetary policy independence. After COVID, the Union government's deficit gradually narrowed while the quality of expenditure improved. This can be measured through the RECO ratio, revenue expenditure for every rupee of capital outlay. Between 2022 and 2025, the RECO ratio improved from 5.9 to 4.3, based on RBI data. Over the same period, capital outlay as a share of the fiscal deficit increased from around 17% to more than half.

This suggests that in the post-COVID period, monetary policy increasingly assumed an active role by setting interest rates independently, while fiscal policy remained relatively passive. Fiscal consolidation, alongside post-COVID monetary tightening, did not necessarily weaken growth because expenditure became more growth-oriented, with greater emphasis on capital spending, which has roughly three times the cumulative multiplier effect of revenue expenditure (Goyal & Sharma, 2018). 

The key to sustaining this combination of fiscal consolidation, better expenditure quality and effective policy coordination is monetary policy independence. Externally, that independence is reinforced by macroprudential measures and timely management of the rupee, helping reduce exchange rate volatility, lower hedging costs and support the smooth flow of goods and capital. Together, this policy framework promotes stronger macroeconomic outcomes while preserving financial and price stability.
