Current Account

Among the 3 countries Malaysia has the lowest ratio but since 2018 ringgit performance of better than S Korea. This could be that S Korea and Thailand historically maintain a ratio of 7, while Malaysia is half of that. For the last two years, S Korea rstio has fallen to an average of 4.

A h8gh current ratio for both countries indicate that both countries export morevthan import while local consumption is relatively low. 

Let see the equation. 

Nation Income Y

is Y=C+I+G+(X-M) which is equivalent to

Y-C-G-I=X-M

Consolidating C and G, therefore Income(Y) less Consumption and G is equal Saving (S) 

S-I = X-M, X-M is the current account ignoring the less significant interest factor and transfer factor. 

Note : Current Account is the sum of the balance of trade (exports minus imports of goods and services), net factor income (such as interest and dividends) and net transfer payments (such as foreign aid)
