Global Monetary Tightening: Why Central Banks Have Limited Options?

Context

1. The global economy is facing a difficult combination of persistent inflation, elevated crude oil prices, geopolitical tensions in West Asia and rising US Treasury yields.
2. These developments are creating a dilemma for central banks. Cutting interest rates too early may allow inflation to rise again, while keeping rates high for too long may slow economic growth, investment and employment.
3. For India, this situation is particularly important because higher global oil prices and a weaker rupee can increase imported inflation and make it difficult for the Reserve Bank of India (RBI) to reduce interest rates.

Understanding monetary policy

1. Monetary policy refers to the actions taken by a country’s central bank to regulate the availability and cost of money and credit in the economy.
2. Its broad objectives include maintaining price stability, controlling inflation, supporting sustainable economic growth and maintaining financial and monetary stability.
3. Central banks generally use two broad approaches:
   1. Monetary tightening: It refers to measures taken by a central bank to reduce excess money and credit in the economy. Common measures include increasing policy interest rates, making borrowing more expensive, reducing liquidity in the banking system and tightening credit conditions.
      1. Effect: Borrowing and spending may decline, helping reduce demand-side inflation. However, excessive tightening can also slow economic activity.
   2. Monetary easing: It refers to measures taken to make money and credit more readily available. Common measures include reducing policy interest rates, injecting liquidity into the banking system, purchasing financial assets, where appropriate and making borrowing cheaper.
      1. Effect: Consumption and investment may increase, supporting economic growth. However, excessive easing can create inflationary pressure.

Why are central banks facing a dilemma now?

1. The current situation is different from a conventional economic slowdown.
2. Normally, when growth weakens and inflation declines, central banks can reduce interest rates to support the economy. But when inflation remains high even as growth slows, policymakers have fewer options.
3. This is because two important objectives are pulling monetary policy in opposite directions:
   1. Inflation control: Central banks may need to maintain high interest rates to prevent prices from rising further.
   2. Economic growth: Businesses and households need lower borrowing costs to support investment, consumption and employment.
4. This creates a policy trade-off between controlling inflation and supporting growth.

How is the current cycle different from 2022?

The biggest difference is the starting level of interest rates.

1. Monetary Tightening in 2022
   19. Low Interest Rates: During 2020–21, central banks reduced interest rates to support economies affected by COVID-19.
   20. Rising Inflation: As economies reopened, demand increased, while supply-chain disruptions continued, pushing up inflation.
   21. War Impact: Russia’s invasion of Ukraine in February 2022 increased global food and energy prices.
   22. Rate Hikes: Central banks increased interest rates to control inflation.
       2022. US Federal Reserve: Started raising rates in March 2022.
       2023. European Central Bank: Started raising rates in July 2022.

• RBI: Increased the repo rate from 4% in May 2022.

2. The Current Situation
   22. Higher Starting Rates: Interest rates are already higher than the exceptionally low levels of 2020–22.
   23. High Borrowing Costs: Loans are already relatively expensive in several economies.
   24. Fresh Inflation Pressure: New geopolitical tensions and energy-price shocks are creating inflationary pressure.
   25. Growth Concerns: Further rate hikes could slow economic growth, while early rate cuts could increase inflation again.
   26. Policy Dilemma: Central banks must balance inflation control with the need to support economic growth.

Why are central banks finding it difficult to cut interest rates?

There are four major reasons:

1. Persistent Inflation: Inflation is a sustained rise in the general prices of goods and services. Even when inflation falls, the overall price level may remain high. Lower interest rates make borrowing cheaper, increasing consumption and investment. Higher demand can push prices up again if supply cannot keep pace.
2. High Crude Oil Prices: Expensive oil increases transportation and logistics costs. Manufacturing, electricity and fertiliser costs may also rise. It can lead to cost-push inflation as businesses may pass these additional costs on to consumers, increasing prices.
3. Rising Government Borrowing and Bond Yields: Governments raise money by issuing bonds. Investors demand higher returns (higher yield) to lend money to governments. Higher yields can increase borrowing costs for businesses, households and governments. This can discourage investment and increase the government’s debt burden.
4. Global Financial Uncertainty: Wars and international tensions create uncertainty in global markets. Tariffs and trade barriers can increase production and import costs. Also, capital flow volatility can affect currencies and financial stability.

So, central banks prefer to avoid premature interest-rate cuts until inflation and economic conditions become clearer.

Crude oil: The central constraint for monetary policy

Crude oil is particularly important because it affects both inflation and a country’s external balance.

Why is India particularly vulnerable to rising crude oil prices?

India imports a large share of the crude oil it consumes. Therefore, rising international oil prices affect the economy in several ways.

1. Higher import bill: India spends more foreign exchange to import crude oil, increasing the merchandise trade deficit.
2. Pressure on current account: A higher oil import bill can widen the current account deficit, other things remaining unchanged.
3. Rupee depreciation: Higher demand for foreign currency to pay for imports can put pressure on the rupee. Capital flows and RBI intervention also influence the exchange rate.
4. Imported inflation: A weaker rupee makes dollar-priced crude oil and other imports more expensive, increasing domestic production costs and prices.
5. Pressure on monetary policy: The RBI may find it difficult to cut interest rates if rising oil prices and rupee depreciation increase inflationary pressure.

US Treasury Yields: Why Do They Matter to the World?

1. US Treasury bond: It is a debt instrument issued by the US government to borrow money. Investors lend money to the US government by purchasing these securities. In return, they receive interest and repayment according to the bond’s terms. They are considered major safe-haven assets because they are backed by the US government.
2. Treasury yield: It is the return an investor earns on a bond based on its purchase price and future payments. There is an inverse relationship between bond prices and yields (when bond prices rise, yields generally fall and vice-versa).
3. Why are US Treasury yields rising?
   1. US Treasury yields are rising due to persistent inflation concerns, high crude oil prices, increased US government borrowing, expectations of higher-for-longer Federal Reserve interest rates, and growing demand for capital to finance AI infrastructure investments.
4. How do higher US Treasury yields affect India?
   1. Higher US Treasury yields means that US dollar assets become more attractive to global investors. This leads to possible movement of capital away from emerging markets like India. This may put possible pressure on the Indian rupee leading to higher import costs and additional inflationary

Developed vs developing economies: Who faces what challenges?

Both developed and developing economies face the challenge of controlling inflation without damaging economic growth. However, emerging economies such as India can be more vulnerable to external shocks.

Developed economies	Developing economies
Generally have deeper and more developed financial markets.	May have less depth in financial markets and greater dependence on foreign capital.
Often have stronger domestic currencies and greater international borrowing capacity.	Currency depreciation can increase the cost of foreign-currency borrowing and imports.
Some are less dependent on imported energy, although this varies by country.	Energy-importing countries are particularly exposed to oil-price shocks.
Can have more established social-security systems to support vulnerable groups.	Higher food and fuel expenditure can disproportionately affect lower-income households.
Face risks from public debt and inflation.	Face these risks along with volatile capital flows and external financing pressures.

Overall Impact on the Indian Economy

1. Inflation: Higher oil and transport costs increase prices of goods and services.
2. Current Account Deficit (CAD): Higher oil imports can widen the current account deficit.
3. Exchange Rate: Higher US yields may trigger capital outflows and weaken the rupee.
4. Fiscal Burden: Fuel tax cuts and subsidies can reduce revenue or increase expenditure.
5. Economic Growth: Higher costs reduce household spending and business investment.
6. RBI Policy: The RBI must balance inflation control, growth and financial stability.

What options do central banks have?

Central banks are not completely powerless. However, each available option involves trade-offs.

Policy option	Purpose	Limitation
Maintain high interest rates	Prevent inflation expectations from rising	Can weaken consumption and investment
Increase interest rates further	Control persistent inflationary pressure	May slow growth and increase borrowing costs
Reduce interest rates	Support borrowing, consumption and investment	May worsen inflation if price pressures remain high
Manage liquidity	Maintain orderly money-market conditions	Cannot directly resolve a global oil supply shock
Foreign-exchange intervention	Reduce excessive exchange-rate volatility	Cannot permanently defend a currency against fundamental pressures
Clear communication and forward guidance	Influence expectations and reduce uncertainty	Effectiveness depends on credibility and market confidence

Why can’t monetary policy alone solve an oil-price shock?

1. Suppose international crude oil prices rise because of a disruption in supply.
2. The RBI cannot produce more crude oil or restore disrupted shipping routes by increasing interest rates.
3. However, it can try to prevent the initial increase in energy prices from spreading into general inflation through higher wages, prices and inflation expectations.
4. This is why central banks must distinguish between:
   1. First-round effects: The direct impact of higher oil prices on fuel and related costs.
   2. Second-round effects: When the initial price increase spreads into wages, transport charges, production costs and prices of other goods and services.
5. Monetary policy is particularly important in preventing second-round effects from becoming persistent.

What should India prioritise?

1. For India, the long-term response should focus on reducing structural vulnerabilities rather than depending entirely on short-term monetary measures.
2. Some important priorities are:
   1. Energy diversification: Expand solar, wind, nuclear power and other domestic energy sources.
   2. Strategic petroleum reserves: Strengthen the ability to manage temporary disruptions in crude oil supply.
   3. Domestic manufacturing: Reduce excessive dependence on imported critical inputs.
   4. Fiscal discipline: Maintain sufficient fiscal space to respond to external shocks.
   5. Export competitiveness: Strengthen exports to support foreign-exchange earnings.
   6. Financial market development: Deepen domestic capital markets and broaden the investor base.

Conclusion

The current global monetary environment is difficult because inflationary pressures are returning even when interest rates are already relatively high. Central banks must carefully balance price stability with economic growth.

Frequently Asked Questions (FAQs)

Q1: What is the main dilemma central banks face in the current economic landscape?

Central banks must balance controlling persistent inflation with preventing a major slowdown in economic growth and employment.

Q2: How does the current monetary cycle differ from the tightening phase of 2022?

The current cycle starts with already elevated interest rates, making any further hikes far more dangerous for economic growth.

Q3: Why are high crude oil prices a major constraint for central banks?

Expensive oil increases production and transport costs, triggering cost-push inflation that prevents central banks from safely lowering interest rates.

Q4: Why does rising global oil prices make India particularly vulnerable?

High oil prices widen India’s current account deficit and weaken the rupee, leading to a surge in imported inflation.
