The Singapore economy experienced continuous real GDP growth from 2001 to 2007, suffered a downturn in 2008, but rebounded strongly in 2010 due to manufacturing and tourism growth. Government borrowing in Singapore is fiscally sustainable, serving mainly for investment, and the country has maintained current account surpluses since the late 1980s. In contrast, Nigeria's economy, while growing, remains smaller and more volatile compared to the U.S., with significant fluctuations influenced by global economic conditions and oil price dependence.
