Why did Naoero face economic trouble when phosphate deposits declined?

Naoero faced severe economic trouble as its phosphate deposits—the island's primary resource and sole export—approached exhaustion by the late 20th century. This decline triggered a significant drop in national earnings, pushing the country toward bankruptcy by the early 21st century.12

The economic crisis was exacerbated by several factors:

• Loss of Investment Value: While the government had invested a major portion of its phosphate earnings abroad to prepare for the post-mining era, these funds lost much of their value due to fraud and risky investments.2
• Lack of Economic Diversification: The island struggled to develop alternative resources or income streams, as agriculture, fishing, and tourism remained of minor value to the economy.1
• High Dependency: Because the phosphate industry and government services provided nearly all salaried employment, the collapse of the industry left the nation with few domestic economic pillars.1

To manage the resulting financial instability, the government was forced to implement austerity measures, including cuts to public services.2
