Indonesia's persistent current account deficits and reliance on foreign portfolio inflows to fund them were among the main contributors to the volatility of the rupiah currency in the past.
Economists have said last year's current account surplus should help anchor the currency this year as major economies prepare to tighten global liquidity amid high inflation.
However, signs of an acceleration in the U.S. Federal Reserve's monetary tightening plans had already spurred outflows from the bond market, Bank Indonesia's data showed, squeezing the capital and financial accounts in the fourth quarter.
The current account surplus also narrowed to $1.42 billion, or 0.4% of GDP, in the fourth quarter, from a $4.97 billion surplus, or 1.7% of GDP, in the previous three months, on rising imports and freight costs.
