Over the past few decades, global government debt has continued to grow, a trend that has attracted widespread attention, especially during economic crises. Facing new economic challenges, governments around the world have to rely on borrowing to adjust their economies, maintain social stability, and reduce unemployment. Government debt is not only a tool for fiscal operations, it also carries a country's resilience and resilience in the face of crises.
Government borrowing can be seen as a "buffer" for the economy. During an economic recession, the government can use deficit finance to maintain public services.
The source of government debt is usually past budget deficits, when government spending exceeded revenue and it had to rely on borrowing to fill the gap. Taking 2020 data as an example, global government debt reached 87.4 trillion US dollars, accounting for 99% of global GDP. Behind the figure of government debt reflects society's need for funds required for crisis management, especially in major events such as large-scale epidemics or economic depression.
According to the Organization for Economic Cooperation and Development, the ratio of government debt to GDP is an important indicator for assessing government fiscal sustainability.
From a historical perspective, the evolution of government debt also reflects the process of a country's political and economic development. As early as the 17th and 18th centuries, Britain established a parliamentary system that included creditors, so that government borrowings could be guaranteed. The establishment of this system not only enhanced the country's credit, but also opened up a way for the government's financial operations.
The recent COVID-19 epidemic has contributed to the rise in government debt. In order to cope with the economic impact of the epidemic, various countries have implemented large-scale fiscal stimulus measures. Although these measures have effectively slowed the economic downturn in the short term, they pose a challenge to the government's long-term fiscal sustainability.
Fiscal stimulus measures, while keeping the economy running, may also create future debt pressure.
Excessively high government debt levels may cause interest rates to rise, thereby crowding out private investment funds. According to World Bank research, government debt exceeding levels will have a negative impact on economic growth. For example, if the ratio of government debt to GDP in developed countries exceeds 77%, future annual economic growth will decline.
In order to avoid debt crises, many countries have established rules and limits on budget balance. For example, policies such as Sweden's "debt anchor" and Germany's "debt brake" are designed to control the growth of government debt. In addition, the EU also requires member states to comply with the Stability and Growth Pact and limit government debt to less than 60%.
Generally speaking, government debt, as an important tool to deal with economic shocks, has both its advantages and challenges. In the future, how countries can effectively use debt to balance current economic needs and long-term fiscal health will be a question worthy of in-depth discussion.
