On November 28, 2024, the Bank of Korea surprised the markets by cutting its benchmark interest rate by 25 basis points to 3.00%. This move, which diverged from market expectations that the central bank would maintain its rate at 3.25%, reflects a broader global trend that is raising important questions about the health of the global economySouth Korea, with its heavy reliance on international trade, has long been regarded as a bellwether for global economic trendsDue to its position as an export-driven economy, any shifts in its policy or economic performance are often viewed as indicators of the global economic pulseThis makes South Korea a “canary in the coal mine,” a term that alludes to how its economic fluctuations can often presage broader shifts in the global market.
The move by the Bank of Korea is part of a much larger trend that is unfolding across the world—central banks, from developed economies to emerging markets, are loosening monetary policy
The Federal Reserve, the European Central Bank (ECB), and numerous other central banks have made similar cuts in recent monthsThis global trend of rate reductions has sparked intense debate among economists and investors alike: What lies behind this wave of rate cuts, and what implications might it have for the global economy?
The Pressure of Slowing Economic Growth
The most immediate driver behind this widespread trend is the pressure of slowing economic growthBy the third quarter of 2024, the Federal Reserve had already reduced its key interest rate by 25 basis points, bringing it to the range of 4.50% to 4.75%. This decision came in response to a growing sense that economic activity was faltering, not just in the U.Sbut across the globeGeopolitical tensions, escalating trade wars, and an overall rise in global economic uncertainty have taken their toll on investment sentiment

In many regions, businesses are showing reluctance to expand, and consumer confidence is low, leaving a vacuum in both consumption and investment.
In this context, central banks have turned to rate cuts as an important tool for stimulating economic activityLower interest rates encourage borrowing by both consumers and businesses, which can spur spending, investment, and ultimately job creationFor example, with more affordable loans, companies may expand their operations, purchase new machinery, or hire additional employees, all of which have a stimulative effect on the broader economy.
The Inflation Target Dilemma
Another crucial factor driving the global trend of rate cuts is the persistent underachievement of inflation targetsCentral banks, especially in developed economies, often set a 2% inflation target as an ideal goal for price stabilityHowever, a combination of factors—including weak demand, overproduction, and other structural challenges—has made it difficult for inflation to reach this target
In many cases, inflation has remained stubbornly below target, and central banks have lowered interest rates as a way of stimulating demand and nudging inflation upward.
For example, despite years of accommodative monetary policies, the ECB has struggled to meet its 2% inflation targetBy lowering interest rates further, it hopes to prompt borrowing and spending, which would, in theory, push prices higherHowever, the challenge is that these low rates can only do so much when broader structural issues—such as demographic shifts, global overcapacity, and technological deflation—are keeping prices suppressed.
Currency Wars and International Competitiveness
Beyond these economic factors, international competition and the so-called “currency wars” play a significant role in the global rate-cutting spreeWhen one country’s central bank cuts interest rates, it often triggers a chain reaction as other central banks feel the pressure to follow suit
This is particularly true in economies with significant export sectorsA lower interest rate can cause a nation’s currency to depreciate, which makes its goods and services more competitive in international markets.
Take Australia, for instanceThe Reserve Bank of Australia (RBA) recently lowered its rates, which resulted in a sharp depreciation of the Australian dollarThis made Australian exports more attractive, especially to key trading partners like China and the U.SAs a result, other central banks have been under pressure to follow suit in order to maintain their export competitivenessThis phenomenon, while not officially recognized as a "currency war," is a common occurrence in a world where many countries are vying for a larger slice of the global trade pie.
Mitigating Financial Risk
Rate cuts also serve as a tool for mitigating financial risk, especially in times of global uncertainty
By lowering borrowing costs, central banks aim to reduce the debt burdens on both individuals and corporationsIn environments where credit tightening can lead to financial stress, reducing interest rates helps prevent credit defaults, bankruptcies, and potentially broader financial crisesThis is particularly important in times of economic and geopolitical volatility, where the risk of financial instability is heightened.
The European Central Bank, the Bank of Japan, and the Bank of England have all taken similar actions, with a focus on ensuring financial stability amid heightened global risksIn a world where debt levels are already high, especially in developed markets, it is seen as prudent to keep interest rates low in order to avoid triggering a financial crisisA sharp spike in borrowing costs could set off a chain reaction of defaults, particularly in highly leveraged sectors like real estate and corporate debt markets.
The Long-Term Implications
While interest rate cuts can provide a short-term economic boost by lowering borrowing costs and encouraging spending and investment, there are risks associated with prolonged reliance on monetary policy
One key concern is the potential for asset bubblesWhen borrowing becomes cheap and abundant, there is a tendency for excessive amounts of capital to flood into asset markets, inflating prices beyond sustainable levelsThis can lead to overvaluation in housing, stock markets, and other investment sectors, creating the conditions for an eventual correction.
Furthermore, sustained low rates can exacerbate debt problems, as companies and households take on more debt in order to take advantage of cheaper financingIf the global economy turns sour, or if interest rates are eventually raised again, these heavily indebted entities may find themselves unable to meet their obligations, leading to defaults and financial instability.
Moreover, the long-term reliance on low interest rates can lead to a distortion in the natural functioning of markets, where credit is allocated not based on genuine demand for investment but on the availability of cheap money
Over time, this can misallocate resources, leading to inefficiency in the economy.
The Road Ahead
In the end, the global trend of rate cuts is not simply a response to current economic conditions but also a strategy to prepare for future uncertaintiesAs the world navigates a complex and unpredictable economic landscape, the key challenge for central banks will be to strike the right balance between stimulating growth and avoiding the creation of new financial risks.
The decision to cut rates is ultimately a delicate balancing actCentral banks must carefully monitor the evolving economic landscape and ensure that their actions do not inadvertently sow the seeds of future crisesIn this environment, the wisdom of policymakers will be tested as they try to stimulate growth without over-relying on monetary policy to the point of creating long-term risksFor now, the global wave of rate cuts continues, and the world waits to see how these moves will shape the future of the global economy.
