Let's analyze the given statements regarding central banks, interest rates, and monetary policy, especially in the context of the recent post-pandemic period.

Analyzing Statement I: Post-Pandemic Interest Rate Hikes

Statement-I says: "In the post-pandemic recent past, many Central Banks worldwide had carried out interest rate hikes."

During and after the COVID-19 pandemic, governments and central banks implemented various measures to support economies. These included fiscal stimulus and very low interest rates (even zero or negative in some cases) to encourage borrowing and spending. However, these measures, combined with supply chain disruptions and pent-up demand, led to a significant rise in inflation across many countries.

In response to this rising inflation, central banks around the world, such as the US Federal Reserve, the European Central Bank, the Bank of England, and many others, began to increase their policy interest rates. The goal was to curb inflation by making borrowing more expensive, thereby reducing spending and cooling down the economy.

Therefore, Statement-I accurately reflects the actions taken by many Central Banks worldwide in the post-pandemic recent past to combat rising prices through interest rate hikes.

Based on this analysis, Statement-I is correct.

Examining Statement II: Central Banks and Monetary Policy

Statement-II says: "Central Banks generally assume that they have the ability to counteract the rising consumer prices via monetary policy means."

One of the primary mandates of most Central Banks is price stability, which means keeping inflation under control. They use various tools as part of their monetary policy to achieve this goal. The main tool is typically adjusting the policy interest rate.

Here's how monetary policy tools are generally assumed to work against rising consumer prices (inflation):

• Interest Rate Adjustments: Raising interest rates makes borrowing more expensive for businesses and consumers. This can lead to reduced investment by businesses and less spending by consumers.
• Reduced Money Supply: Higher interest rates can also discourage lending by commercial banks, which can slow down the growth of the money supply in the economy.
• Impact on Demand: Lower borrowing and spending activity reduces the overall demand for goods and services. When demand falls relative to supply, the pressure on prices tends to decrease.

Central banks operate on the assumption that these actions, through their impact on borrowing costs, credit availability, and aggregate demand, can influence the rate of inflation. While the effectiveness can vary depending on economic conditions and other factors, the fundamental belief that monetary policy can counteract rising consumer prices is central to how Central Banks operate.

Based on this analysis, Statement-II is correct.

Linking Statement I and Statement II: Explanation

Now let's consider if Statement-II is the correct explanation for Statement-I.

Statement-I describes the action: Central Banks carried out interest rate hikes post-pandemic.

Statement-II describes the rationale or belief behind such actions: Central Banks believe their monetary policy tools, like adjusting interest rates, can counteract rising consumer prices (inflation).

In the post-pandemic period, the problem faced was rising consumer prices (high inflation). As explained in Statement-II, Central Banks believe that raising interest rates (a monetary policy tool) is a way to counteract this problem. Therefore, the actions described in Statement-I (interest rate hikes) were a direct consequence of the belief described in Statement-II (that monetary policy can fight inflation) in the face of rising consumer prices post-pandemic.

Thus, Statement-II provides the fundamental reason or assumption that drives the actions mentioned in Statement-I. Statement-II explains *why* Central Banks would choose to hike interest rates when faced with rising prices.

Therefore, Statement-II is the correct explanation for Statement-I.

Conclusion

Both Statement-I and Statement-II are correct, and Statement-II correctly explains Statement-I.

Revision Table: Key Concepts

Additional Information: Monetary Policy Tools

Besides adjusting the policy interest rate, Central Banks have other tools at their disposal as part of their monetary policy to manage the economy and influence inflation:

• Open Market Operations: Buying or selling government securities in the open market. Buying securities injects money into the banking system, potentially lowering interest rates; selling securities withdraws money, potentially raising interest rates.
• Reserve Requirements: The amount of funds that banks must hold in reserve against deposits. Changing this requirement can affect the amount of money banks have available to lend.
• Discount Rate: The interest rate at which commercial banks can borrow money directly from the Central Bank.
• Forward Guidance: Communication about the Central Bank's future intentions regarding monetary policy.
• Quantitative Easing (QE) / Quantitative Tightening (QT): Large-scale asset purchases (QE) or sales (QT) to inject or withdraw liquidity from the financial system, often used when interest rates are already very low.

The assumption that these tools can influence economic variables, including rising consumer prices, is fundamental to how Central Banks operate to achieve their mandates, which typically include price stability, maximum employment, and moderate long-term interest rates.
