The rupee declined 28 paise to 76.46 against the US dollar in opening trade on Tuesday, following a negative trend in domestic equities amid heightened concerns over global oil supplies.

Meanwhile, the dollar index, which gauges the greenback's strength against a basket of six currencies, rose 0.17 per cent to 98.66.

The rupee opened weak against the dollar this Tuesday as Treasury yields surged after the US Federal Reserve Chair Jerome Powell signalled a willingness to raise rates more aggressively to combat inflation, said Sriram Iyer, senior research analyst at Reliance Securities.

Moreover, most Asian and emerging market peers were also weak this Tuesday morning and a continued rise in crude oil prices will also weigh on domestic sentiments.
