The Rupee opened largely unchanged on Tuesday, with traders assessing the impact of the central ?bank’s partial rollback of FX curbs alongside looming U.S.-Iran ?risks.The Reserve Bank of India, after ?market hours on Monday, partially rolled back restrictions it had imposed ?on corporates and other users and on certain related-party ?transactions undertaken by banks. The RBI withdrew directions barring banks from offering non-deliverable forwards ?to resident and non-resident users and dropped curbs that prevented users from rebooking foreign ?exchange derivative contracts. The restrictions were introduced about three weeks ago, primarily to prevent corporates from engaging in arbitrage between onshore and offshore markets. That move, coupled with prior measures to cap the onshore ?position size of banks, helped the rupee recover from a all-time ?low of 95.21 hit in late March. On balance, the RBI's rollback is likely to ?put ?a bit of pressure on the rupee and push premiums higher at the margin, a treasury official at a foreign bank said. The rupee and other Asian currencies will have to contend ?with uncertainty over whether a second round of U.S.-Iran ?talks ?will take place, with the deadline for the two-week ceasefire set to lapse this week.

The dollar ?index , which measures the greenback against a basket of currencies including the yen and the euro, was steady at 98.087 after a 0.2% decline on Monday. The yen was steady at 158.955 per dollar, continuing to hover near the crucial 160 level that traders see as the line in the sand for intervention. The kiwi traded at $0.59085 , up 0.3%. New Zealand's annual inflation ?rate was unchanged ?at 3.1% in the first quarter, above the central bank's target range, increasing the likelihood of further rate hikes this year. Oil prices fell on Tuesday, reversing gains in the previous session, on ?expectations peace talks between the U.S. and Iran will take place this week and allow more supply to flow from the key Middle East producing region. Brent crude futures declined 54 cents, or 0.6%, at $94.94 a barrel at 0300 GMT. U.S. West Texas Intermediate (WTI) for May fell $1.11, or 1.2%, to $88.50.
