Anchoring of Inflation Expectations

Anchoring of inflation expectations refers to the degree to which households, businesses and financial markets believe that a central bank will succeed in keeping inflation close to its announced target over the medium term, even when current inflation temporarily deviates from that target due to a specific shock. When expectations are well 'anchored,' a temporary price shock, such as a spike in food or fuel prices driven by a poor monsoon or a global crude-oil disruption, is generally expected to fade rather than persist, so wage negotiations, price-setting decisions and long-term contracts continue to be made as though the announced target will hold, which helps the shock actually fade as expected, a self-reinforcing property. The danger of 'de-anchoring' arises when a central bank repeatedly tolerates above-target inflation, for instance by consistently 'looking through' food and fuel price pressures on the reasoning that they are supply-side and beyond monetary policy's reach, without ever demonstrating that it will act if the pattern persists. If households and firms come to expect that above-target inflation will not be resisted, they begin building that expectation into wage demands, price increases and contract terms, and the originally temporary supply shock can become embedded as a permanent, self-fulfilling shift in the price level, a process that is difficult and costly to reverse once expectations have moved. This tension is central to debates about flexible inflation targeting, the framework under which India's Reserve Bank of India operates a statutory target of 4 per cent CPI inflation with a tolerance band of plus or minus 2 percentage points, set by the Central Government under Section 45ZA of the RBI Act, 1934. The RBI's Monetary Policy Committee is legally bound to the headline CPI target rather than to core inflation (which excludes volatile food and fuel components), which is precisely why a decision to hold rates steady despite above-target headline CPI, reasoning that the pressure is concentrated in food and fuel and that core inflation is well contained, carries a real risk of de-anchoring if repeated too often or for too long without clear justification.

• 1 Anchored expectations: households/firms believe the central bank will keep inflation near target over the medium term, even amid temporary shocks.
• 2 Well-anchored expectations are self-reinforcing: they help a temporary shock actually fade, since wage/price-setting isn't adjusted upward in anticipation of persistence.
• 3 'De-anchoring' risk arises when a central bank repeatedly tolerates above-target inflation without demonstrating it will act if the pattern persists.
• 4 If expectations de-anchor, a temporary supply shock (e.g. food/fuel) can become embedded as a permanent price-level shift.
• 5 India's RBI statutory target is headline CPI at 4 per cent (plus/minus 2 percentage points), set under Section 45ZA of the RBI Act, 1934, not core inflation.
• 6 The Monetary Policy Committee (Section 45ZB) is legally accountable to the headline target, making repeated 'looking through' of food/fuel inflation a contested but examinable practice.
• 7 Central to the debate over whether flexible inflation targeting is being applied correctly or the mandate is being redefined by practice.

The RBI's August 2026 decision to hold rates despite headline CPI above target, reasoning that pressure was concentrated in food and fuel while core inflation stayed near 2.3-2.5 per cent, was framed as a test of whether inflation expectations remain anchored enough to permit repeatedly looking through such shocks.
