Can governments buy current account surpluses with fiscal and currency policy?
Core argument: Regression results suggest that raising the fiscal balance by $1 tends to raise the current account by about $0.30.
Table 1 presents regression results. The evidence strongly suggests that governments can buy current account surpluses. Raising the fiscal balance by $1 tends to raise the current account by $0.30 [Table 1, first row]. Issuing $1 of domestic currency debt to buy foreign-currency assets (foreign exchange intervention) raises the current account anywhere from $0.20 to $1.00, with a value around $0.50 to $0.60 most plausible [Rows 2 though 5]. NOF is Net Official Flows, and NOS is the stock of net official foreign assets. The most powerful policy, as exemplified by Norway and Singapore, is to run a fiscal surplus and invest the proceeds in foreign-currency assets. In that case, $1 buys a current account surplus of around $0.80 or so. The results are supported by annual panel regressions of current accounts and cross-country stock regressions of cumulated current accounts or stocks of net foreign assets. The estimated effects in the panel regressions may be biased down slightly by incomplete modeling of lagged effects.
