India is likely to post its first current account surplus in nine years in the latest quarter, which should bolster the rupee though it is not a good sign for the economy as it reflects weak investment demand at home and subdued exports, analysts said. Forecasts call for a surplus of US$4 billion, or 0.8% of GDP, in the April-June quarter. That compared with a deficit of $6.2 billion, equivalent to 1.2% of GDP, in the same quarter a year ago.
