The global COVID-19 pandemic has had a significant impact on various aspects of life throughout the world, especially in developing countries. The economic sectors hardest hit include trade, foreign investment and the tourism sector. The closure of borders and the implementation of social restrictions led to a sharp decline in economic activity. The trade sector experienced major disruption due to broken supply chains. Many developing countries depend on exports of manufactured goods and raw commodities. A decrease in global demand causes a decrease in the prices of these goods, which directly affects the country’s income. For example, oil producing countries experienced a crisis when world oil prices fell. Foreign direct investment (FDI) also experienced a drastic decline. Economic uncertainty and health concerns are forcing investors to hold back their investments. Developing countries, which often lack strong infrastructure and depend on foreign investment for economic growth, face serious sustainability risks. For example, many planned infrastructure projects were postponed or cancelled. Tourism, which is one of the main sources of income for developing countries, has also taken a heavy hit. With restrictions on international travel, many destinations dependent on the tourism sector have seen a drastic decline in visits. Countries such as Thailand and Indonesia, which rely on income from foreign tourists, have had to face long-term consequences in terms of lost jobs and tax revenues. The informal sector, which is a source of livelihood for many people in developing countries, is particularly vulnerable to the impact of the pandemic. Many workers in this sector have lost their livelihoods due to business closures and mobility restrictions. Not having strong social security makes them sink deeper into poverty. One of the less visible but significant economic impacts is an increase in national debt. To overcome this crisis, many governments in developing countries were forced to borrow funds, both from international institutions and bilaterally. A rising debt burden could limit the country’s capacity to invest in important sectors such as education and health in the future. On the other hand, this pandemic also brings opportunities for developing countries to modernize and diversify their economies. With increasing technology adoption, many countries are starting to shift towards digitalization, which could provide a new foundation for economic growth in the post-pandemic era. Innovations in the health and agriculture sectors also show that developing countries can use this crisis as an opportunity to improve existing systems and practices. However, to benefit from these opportunities, proactive policies and international support are needed. Global cooperation on vaccine access and development assistance is critical to ensuring developing countries can bounce back and build greater economic resilience. The success of countries in dealing with the economic impact of the pandemic depends largely on their ability to adapt to new conditions and capitalize on emerging trends in the post-pandemic global economy.
