Q.Read the following news published on September 26, 2022 : “The central bank has increased the benchmark lending rate by 140 basis points.” Identify the likely cause and consequences behind this action taken by the Reserve Bank of India.

The Reserve Bank of India raised the repo rate (benchmark lending rate) by 140 basis points in response to rising inflation. When inflation accelerates beyond the RBI's target range of 2–6%, the central bank tightens monetary policy to cool demand and stabilize prices.

By increasing the repo rate, the RBI makes borrowing costlier for commercial banks, which in turn raise lending rates for households and firms. Higher interest rates discourage consumption and investment spending, reducing aggregate demand in the economy. Lower demand eases upward pressure on prices, helping bring inflation back toward the target. …

The Economic Context: Why Central Banks Raise Interest Rates

A central bank's benchmark lending rate—in India, the repo rate—is the rate at which commercial banks borrow short-term funds from the RBI. When the RBI announces a 140 basis point hike (1 basis point = 0.01%, so 140 bp = 1.4%), it signals a deliberate tightening of monetary policy. The question is: what compels such a move?

The likely cause in September 2022 was elevated and persistent inflation. India, like much of the world in 2022, faced inflationary pressures from multiple sources: supply-chain disruptions lingering from the pandemic, surging global commodity prices (especially crude oil and food grains), and the spillover effects of geopolitical tensions (the Russia-Ukraine conflict pushed up energy and fertilizer costs). When actual inflation overshoots the RBI's target band—typically 4% ± 2%—the central bank is mandated to act. Raising the repo rate is the primary tool to rein in demand-driven inflation.

The mechanism works through the cost of credit. A higher repo rate makes it more expensive for commercial banks to borrow from the RBI, and they pass this cost on to households and firms in the form of higher lending rates on loans—home loans, car loans, business credit. Costlier borrowing discourages consumption (fewer big-ticket purchases) and investment (firms postpone expansion plans). Aggregate demand in the economy contracts, reducing upward pressure on prices.

Consequences of the Rate Hike

The effects ripple through multiple channels, some intended and some unavoidable trade-offs.

On Inflation (the intended target):

Higher interest rates cool demand, especially for interest-sensitive goods like housing and durables. As consumption and investment slow, firms face weaker pricing power, and inflation moderates over the medium term (6–12 months, given the lags in monetary transmission). This is the RBI's primary objective.

On Growth and Output:

Tighter credit conditions mean lower investment spending by firms and reduced consumer spending on durables. Aggregate demand falls, and so does GDP growth. The economy may slow noticeably—this is the policy trade-off. The RBI accepts a growth sacrifice to stabilize prices, especially when inflation threatens to become entrenched in expectations.

On Borrowers:

Existing borrowers with floating-rate loans (most home loans in India are linked to the repo rate via the external benchmark system) see their EMIs rise immediately. New borrowers face higher loan costs, dampening demand for credit. This is contractionary by design.

On Savers and Depositors:

Higher policy rates eventually translate into better returns on fixed deposits and savings instruments. Real returns (nominal rate minus inflation) improve if inflation falls faster than deposit rates adjust. This redistributes income toward savers, though the effect is gradual.

On the Exchange Rate:

Higher domestic interest rates attract foreign portfolio investment (FPI) seeking better returns, increasing demand for the rupee. This can lead to rupee appreciation, which helps contain imported inflation (cheaper imports) but hurts export competitiveness. In 2022, however, the rupee was under depreciation pressure from global dollar strength and capital outflows, so the rate hike also served to stem rupee depreciation and prevent imported inflation from worsening.
