“Act as appropriate to sustain the expansion🕺🏻”
Well, that's what we call the BOP = CA + KA +others
GDP (output) = Consumption +Gov + Investment + Net trade (services + goods) or Y = C + G + I + (X-M)
Current account (CA)=(X-M) + Net income from abroad + Net current transfers
CA = Savings - Investment
So CA surplus is net savings
CA = (X-M) + Primary + Secondary
-665 = (net goods 5,668 + net services -1,432) + -4330 + -571
Korea had a net negative savings but that was just April. Ytd, it's positive. Notice that the net trade is the same one for GDP. A CA surplus country is a net saver 🐜
