Here's a table of the financial situation of major countries.
The current account balance is the measurement of a country's export and import. If the country has a positive current account balance, it means the country export more than what it imports, earning money from other countries. If the country imports more, its foreign currency reserve is flowing out.
The budget balance is a measurement of government spending. If the figure is a positive one, it means the government collects more taxes than it spends. A positive budget balance enhances the credibility of the nation to pay off its debt.
Interest rate is the cost of capital, the higher the interest rate, the more it costs for a country to borrow.
If the currency you are holding is depreciating very fast, this table serves as a guide for you to pick which currency to invest in. (the US dollar is an exception as the US also profits from seigniorage)
