Moody’s blow to the US credit rating offers a wake-up call for South Korea’s next president
Moody’s Investors Service downgraded the United States’ sovereign credit rating from Aaa to Aa1 on Friday — the first time in more than a century that it had done so. With US debt now surpassing $36 trillion and political dysfunction entrenched in Washington, even the world’s most trusted reserve currency is not immune to market skepticism.
The downgrade is more than a symbolic setback for the US; it serves as a cautionary tale for countries like South Korea, where the warning signs are increasingly hard to ignore.
Moody’s cited years of mounting fiscal deficits, escalating interest payments and the political paralysis in the US that has made both tax increases and meaningful spending cuts virtually impossible.
Moody’s projection is sobering: Without a credible course correction, the US debt-to-GDP ratio could climb from 98 percent last year to 134 percent by 2035. But this trajectory is no longer uniquely American. South Korea, too, is drifting toward fiscal peril — without the benefit of a global reserve currency to cushion the blow.
South Korea’s public finances have deteriorated sharply in recent years. Since the onset of the COVID-19 pandemic, annual budget deficits have hovered near 100 trillion won ($71.7 billion), and tax revenue shortfalls over the past two years have totaled 87.2 trillion won. An anemic economy offers little hope of a natural rebound.
In just the first quarter of this year, the government recorded a 61.3 trillion won deficit — a figure that suggests the red ink will continue to flow. National debt now exceeds 1,175.9 trillion won, up 35 trillion in just three months. According to the International Monetary Fund, South Korea’s debt-to-GDP ratio is projected to reach 54.5 percent this year — slightly above the 54.3 percent average among non-reserve currency economies.
These fiscal pressures are being exacerbated by political short-sightedness. With the June 3 presidential election fast approaching, both leading candidates — Lee Jae-myung of the liberal Democratic Party of Korea and Kim Moon-soo of the conservative People Power Party — are campaigning on expansive populist platforms that largely sidestep the question of how their programs will be paid for.
From expanded child allowances and debt relief for small businesses to increased basic income for rural communities, their proposals would demand tens of trillions of won in new spending each year. Estimates suggest Lee’s pledges could cost over 100 trillion won annually, while estimates for Kim’s exceed 70 trillion. Both camps offer vague promises to “restructure government spending,” but credible funding mechanisms remain elusive.
Such fiscal evasions may prove politically expedient, but they come at a high economic cost. If South Korea’s debt continues to grow unchecked, the consequences will be tangible. Credit agencies such as Moody’s and Fitch have already flagged concerns about the country’s rising deficits and political uncertainty. A downgrade of its sovereign rating would raise borrowing costs across the board, sap investor confidence and put downward pressure on the won — all while the nation faces slowing growth and demographic headwinds.
Unlike the US, South Korea cannot rely on the global demand for its currency or the depth of its financial markets. If the US — with all its institutional and monetary advantages — can lose its top-tier rating, then South Korea is even more vulnerable to market discipline.
The deeper lesson from Moody’s downgrade is not just about debt — it is about denial in the face of a deteriorating reality. South Korea’s next administration will inherit more than a fiscal imbalance; it will confront a defining economic crossroads. The time has come to dispel campaign-season illusions. Candidates must present a coherent, credible path to fiscal stability. Without it, they risk presiding not over a political mandate, but over a crisis of national credibility — one whose consequences may take years, if not decades, to repair.
