As textbook macroeconomics tells us, the current account is equivalent to the domestic saving-investment balance. It is not appropriate to judge whether it is in a good situation or not merely by seeing if there is a deficit or surplus. For example, it is better for emerging economies with high growth potential to borrow abroad, invest at home, and realize higher economic growth.
On the other hand, for countries with limited growth opportunities, it is better to invest abroad and earn higher returns. In these circumstances, countries with abundant investment opportunities are more likely to see investment exceed savings, resulting in a current account deficit. Meanwhile, countries with limited growth opportunities see savings exceed investment, hence a current account surplus.
