Background to Global Monetary Policy Shifts A new trend is emerging in global financial markets. A transition is underway from the era of ultra-low interest rates and low inflation, the so-called 'easy money' period, which persisted for several years after the COVID-19 pandemic. This shift is not merely a temporary phenomenon but is establishing itself as a structural and long-term trend. With the full onset of a high-inflation era, central banks are being challenged with new policy tasks and choices in this evolving environment. Discussions are actively underway regarding what strategies central banks will adopt in this situation and what consequences these will have for national economies. Martin Wolf, chief economics commentator at the Financial Times and a leading figure in global economic analysis, recently stated in an editorial that "the global economy is being reshaped into a new order, triggered by the pandemic." He cited the structural weakening of supply chains, the rise of protectionism due to intensifying geopolitical tensions, and the need for large-scale investment to combat climate change as key factors in this transformation. According to Wolf, prior to the pandemic, trade flows were free and prices tended to be stable, benefiting from globalization. However, after the pandemic, logistics bottlenecks and political conflicts led to rising production costs and supply shortages, driving up global prices. The Russia-Ukraine war, in particular, delivered a significant shock to energy and food prices, becoming a major factor exacerbating inflationary pressures. These complex factors are significant because they represent not temporary shocks but structural changes that will persist for several years. Martin Wolf emphasizes that it has become difficult for central banks to conduct monetary policy in the traditional manner. Central banks, which have historically performed the fundamental roles of stimulating the economy and stabilizing prices through interest rate adjustments, now face an even more complex dilemma between controlling inflation and fostering economic growth. Major central banks, including the U.S. Federal Reserve (Fed), have attempted to curb inflation through continuous interest rate hikes in recent years. However, these tightening policies have been accompanied by side effects such as a stagnant real estate market, weakened consumer sentiment, and sluggish corporate investment. The European Central Bank (ECB) had to respond to external shocks like the energy crisis, while emerging economies bore the burden of capital outflows due to a strong dollar. The global economy remains without a clear direction, caught in a tug-of-war between tightening policies and economic slowdown. What Wolf particularly highlights is a fundamental question about the independence and role of central banks. For decades, central bank independence has been considered a key element for effective price stability. However, in a situation dominated by supply-side shocks, as is currently the case, it is difficult to solve problems solely through interest rate policies. Areas requiring active government intervention are expanding, including industrial policies for supply chain restructuring, green investments to combat climate change, and fiscal spending to strengthen social safety nets. Consequently, the interaction between government fiscal policy and central bank monetary policy is becoming more crucial, demanding close coordination and cooperation between the two. This not only poses a new challenge to the traditional concept of central bank independence but also raises the need to explore new models of cooperation among policymakers. These international economic trends are also significantly impacting the South Korean economy. The Bank of Korea has progressively raised its benchmark interest rate in recent years to curb rapidly soaring prices. This tightening policy has contributed to an increased burden of household debt. South Korea's household debt level is relatively high compared to major developed countries, and interest rate hikes increase households' interest burdens, acting as a drag on consumption and investment. The real estate market, in particular, continues to undergo adjustments, making housing stability and asset formation more challenging for the younger generation. This requires careful attention from policymakers, as it can exacerbate social inequality and intergenerational gaps, extending beyond mere economic issues. The Impact of the Inflationary Era on South Korea Furthermore, due to its highly export-dependent economic structure, South Korea is sensitive to changes in the global economic environment. The strengthening of protectionism and the restructuring of supply chains, as pointed out by Martin Wolf, directly impact South Korean companies. With rising global prices and the spread of protectionism, South Korean firms are simultaneously facing high raw material costs and restricted a
