NX <0.
NX
<0. The BOP equation can be given as NX + K = 0 where K
indicates the capital account. As NX falls, K has to rise. This
means there has to be a capital inflow from abroad. As capital
flows to the US from abroad, foreign savings fall.
NX >0. From
the BOP equilibrium equation, K has to fall which means there has
to be a capital outflow from the domestic country to the foreign
country. Consequently, foreign savings increase.
