Evaluate the role of inflation expectations and central bank signalling in price stability. How effective has the MPC been since 2016?

Inflation expectations are what households and firms believe prices will do next. They shape wage demands and pricing, so they can become a self-fulfilling prophecy. The Finance Act, 2016 set up a statutory Monetary Policy Committee (MPC) focused on price stability [1]. Since then, the RBI's credibility and signals have mattered as much as the repo rate itself.

Role of Expectations and Signalling

• Nominal anchor: People trust the 4% CPI target with a 2–6% band [2]. Because of that trust, short supply shocks fade instead of setting off wage-price spirals.
• Spillover risk: The RBI warns that persistent food inflation and unanchored expectations can spill into core inflation through wages [3].
• Signal, not bludgeon: Monetary policy has limited traction on supply shocks [3], so its real value is as a signal. In October 2026, a deficient monsoon and costly oil pushed the projected Q3 inflation to 6%, the band's upper edge. The MPC responded with a 25 bps hike and a "calibrated tightening" stance [4].
• Limits: Signals cannot make onions or diesel cheaper. They work best alongside fiscal and supply-side measures [5].

Effectiveness of the MPC since 2016

Strengths

• Institutional credibility: Rate decisions moved from the Governor alone to a six-member committee (3 RBI + 3 Centre nominees) [1]. Missing the band for three consecutive quarters counts as a defined failure, which builds in accountability [2].
• Lower, steadier inflation: Average inflation fell to 4.9% under FIT, against 6.8% before it [3]. Expectations became better anchored, and surprises in inflation proved mostly temporary [3].

Weaknesses

• Vulnerable to shocks: The pandemic and war years (2020–23) strained the framework. In 2022-23, food, fuel and core inflation were all above target at the same time [3].
• Headline-target dilemma: Food and fuel make up over 50% of the CPI basket [3]. So supply shocks hit the MPC's mandate directly, even though rates do little about them.

Verdict: On balance the MPC has been effective. It has made real gains in credibility, but it is not shock-proof.

Anchoring expectations is the MPC's strongest tool, and its record since 2016 shows that flexible inflation targeting has largely delivered. Going forward, timely and clearly communicated signals, backed by coordinated fiscal support, can keep the 4% target a credible anchor. That protects poor households and supports stable, inclusive growth (SDG 8).
