Review Questions

• How does a central bank's monetary policy impact inflation and interest rates?
  • A central bank's monetary policy directly affects inflation and interest rates through tools like interest rate adjustments and open market operations. When a central bank raises interest rates, it typically reduces the money supply, which can help lower inflation. Conversely, lowering interest rates encourages borrowing and spending, potentially increasing inflation. Thus, the central bank plays a critical role in maintaining price stability and guiding economic activity.
• Discuss the role of a central bank during economic downturns or financial crises.
  • During economic downturns or financial crises, a central bank takes on a vital role by implementing expansionary monetary policy to stimulate the economy. This may involve lowering interest rates and increasing the money supply to encourage lending and investment. Additionally, central banks provide liquidity to struggling financial institutions as lenders of last resort, preventing widespread failures that could exacerbate economic problems. This intervention helps stabilize financial markets and restore confidence in the economy.
• Evaluate how changes in central bank policies can affect foreign exchange markets and global trade.
  • Changes in central bank policies can have significant ripple effects on foreign exchange markets and global trade. For instance, when a central bank lowers interest rates, it may lead to depreciation of its currency as investors seek higher returns elsewhere. A weaker currency can make exports cheaper and imports more expensive, potentially boosting domestic producers but increasing costs for consumers. Conversely, tightening monetary policy can strengthen a currency, affecting trade balances and international competitiveness. Understanding these connections helps illustrate the broader implications of monetary policy on global economic interactions.
