After hitting a record high of 6.7 per cent of GDP in Q4 2012, the current account deficit is likely to narrow to 4-4.5 per cent of the GDP in the first quarter of this year, owing to some improvement in trade deficit, the Japanese firm said in a research note.
Current account deficit represents the difference between inflows and outflows of foreign currency.
It is likely to worsen in the April-June quarter as the country's trade deficit has worsened again to $17.8 billion in April and Nomura said it expects current account deficit to deteriorate further to $20.8 billion in May.
"The current account deficit remains elevated and we expect it to worsen to 5.5-6 per cent of GDP in Q2 2013, after the expected improvement in Q1," Nomura said, adding, "This suggests that financing the deficit still remains a concern."
It said the sharp deterioration in current account deficit in the April-June quarter is partly due to seasonal factors and also reflects sluggish exports and the front-loading of gold demand in response to falling prices.
On rising gold demand the Japanese brokerage firm said the recent fall in gold prices, if sustained, a moderation in CPI inflation and the RBI restriction on gold imports should taper investment demand for gold, but added that the immediate reaction to lower gold prices has been "higher demand".
Gold prices had fallen to 21-month low at Rs 26,440 per 10 grams in the domestic markets on April 16 due to continued sell-off in the global markets.
