The effects of tightening policy: a triumph or a side effect? The interest rate hike policy vigorously pursued by the U.S. Federal Reserve (Fed) since early 2022 has caused significant repercussions across the economy and financial markets over the past four years. As of March 2026, economic experts continue to debate whether the Fed's tightening policy can truly be deemed successful in terms of controlling inflation. Meanwhile, the global economy, including South Korea, is directly and indirectly affected by this ongoing debate. This column aims to objectively analyze the effects of the Fed's interest rate hike policy, focusing on the divergent perspectives of major international media outlets, and to diagnose its ripple effects on the South Korean economy. Even within the United States, opinions on the impact of the Fed's rate hikes are sharply divided. The Guardian, a progressive media outlet, pointed out in its March 29, 2026, column titled 'The Price of Austerity: Has the Fed's Inflation War Really Succeeded?' that the tightening policy has led to extreme side effects in some areas. It argued that problems such as a stagnant housing market, an increase in small and medium-sized enterprise bankruptcies, and high unemployment rates were triggered by the Fed's aggressive interest rate hikes. In particular, it warned that raising interest rates without resolving the persistent supply chain disruptions following the pandemic could create greater difficulties than it solves. Columnist Emma Jenkins emphasized, "High interest rates have exacerbated the financial burden on consumers and small and medium-sized businesses, ultimately causing significant damage across the entire grassroots economy." She criticized the Fed for underestimating the possibility of a recession and for not adequately reflecting the realities of the grassroots economy in its policy-making process. This assessment aligns with criticisms that the Fed's policy instincts are detached from the real economy. In contrast, the liberal-leaning Financial Times, in an opinion piece titled 'Winning the War on Inflation: The Fed Avoided a Double-Dip,' praised the Fed's monetary policy for boldly curbing rising inflation and saving the economy from catastrophic inflation. David Lockwood, a columnist for the publication, argued, "Learning from past instances where delayed inflation suppression led to economic turmoil like the stagflation of the 1970s, the Fed's proactive stance in implementing interest rate hikes starting in 2022 is highly commendable." He emphasized that by tackling rapid price increases, the Fed increased the likelihood of a soft landing for the economy and averted the worst-case scenario of a double-dip recession. Lockwood stated that temporary economic slowdowns are merely unavoidable side effects in the process of controlling inflation, and such cases offer significant implications for other central banks worldwide. The Fed's Response to Inflation: Implications and Limitations While evaluations of whether the Fed's interest rate hike policy had a positive or negative impact on the U.S. economy remain divided, underlying structural limitations faced by the global economy also persist. The rapidly changing global economic environment post-pandemic exacerbated supply chain issues, and rising raw material and energy prices demanded agile decision-making from central banks worldwide, navigating between existing tightening and easing policies. The Fed steadily raised interest rates, starting with a 0.25% hike in March 2022, with the benchmark rate reaching 5.25-5.50% by July 2023. Although there were some rate cuts in 2024 and 2025 due to slowing inflation, the Fed's benchmark rate remains higher than pre-pandemic levels as of March 2026. This choice by the U.S. has also pressured other countries worldwide to adopt tightening stances. The South Korean economy is also not immune to the Fed's interest rate hikes. If U.S. interest rates rise, capital may flow to the U.S., potentially leading to a depreciation of the Korean won and an increase in the exchange rate. This can drive up import prices and transfer inflationary pressure to the domestic economy. Indeed, in October 2022, the won-dollar exchange rate surged to as high as 1,440 won at one point, causing significant shock to the domestic financial market. While South Korea's Consumer Price Index (CPI) inflation rate gradually stabilized after October 2022, falling to the 3% range in 2023 and the 2% range in 2024, the possibility of experiencing volatility again due to external factors still exists. Economic experts warn that "changes in U.S. interest rate policy significantly constrain the direction of South Korea's monetary policy and can pose serious challenges to economic stability." The Fed's decisions have also had a continuous impact on the domestic financial market. The sharp rise in the exchange rate in the second half of 2022 triggered a steep decline in the domestic asset ma
