4.6.8 (HL)—Persistent current account surplus

A surplus can reflect strong export competitiveness, high saving, weak domestic demand or an exchange rate that keeps exports relatively cheap. It may build foreign assets, but it can also signal under-consumption at home and place adjustment pressure on trading partners.

Judge the surplus by productivity, distribution, domestic investment and how long it can persist—not by treating a positive balance as automatically healthy.

A persistent surplus can suppress domestic consumption or investment when saving is high, create appreciation pressure, and restrain imported inflation while export-led demand supports employment. If authorities resist appreciation, reserve accumulation and stronger domestic liquidity may add inflation. Appreciation can eventually weaken export competitiveness and employment in traded sectors; continued undervaluation can shift adjustment pressure onto deficit partners. Evaluate whether the surplus reflects productivity and sustainable saving or weak domestic demand and underinvestment, plus distributional and international consequences.
