The Rupee opened weak on Tuesday, with oil prices near a three-week high and a ?weaker tone across Asian currencies. The currency has steadily weakened from the high of around 92.70 hit ?10 days ago, with oil-linked flows and hedging-related dollar demand ?chipping away at the positive sentiment created by the Reserve ?Bank of India's measures to support the rupee. Oil appears to have ?settled at a higher level, leaving limited scope for sustained relief ?for the rupee, a currency trader at a private-sector bank said. On a day-to-day basis, there is heavy dollar buying by oil refiners, with little offsetting supply expected ?and limited RBI intervention anticipated. The RBI has been intervening to alleviate ?pressure on the rupee, traders said. However, the support has largely been selective, with the ?central ?bank supplying dollars up to specific levels before stepping back, rather than defending the currency aggressively, they said. Brent crude for June climbed more than 1% to $109.40 a barrel on Tuesday, potentially extending its winning streak ?to ?seven sessions. Faltering efforts to halt the U.S.–Iran ?conflict underpinned prices. Most Asian currencies weakened, compounding the pressure from oil prices on the rupee. ?The dollar index inched up. The Japanese yen steadied in the Asian morning on Tuesday ahead of ?the Bank of Japan's latest policy decision, the first in a busy week for major central banks including ?the Federal Reserve as the Iran war loomed large over policymakers and markets. The yen was flat against the dollar at 159.49 yen, with the BOJ widely expected to keep interest rates on hold at 0.75% later in the day. Central banks in the U.S., the euro zone, the UK and Canada ?are among the others that will deliver rate decisions later this week. The U.S. dollar index , which measures the greenback's strength against a basket of six ?currencies, snapped a ?two-day losing streak with a 0.1% rise on Tuesday to 98.448. Most other currencies were unchanged as markets looked for any signs of progress to end the Iran war. U.S. President Donald Trump discussed a new Iranian proposal on resolving the war with his top national security aides ?on Monday. ?But a U.S. official said later that Trump is unhappy with the proposal ?because it did not address Iran's nuclear program. The euro was down 0.1% at $1.1715, while the British pound was trading at $1.3527. The Australian dollar was flat at $0.7187 and ?its New Zealand counterpart was fetching $0.5908.......
