Mumbai: Indian rupee slipped further to 20.25 to a UAE dirham this morning.
Against the dollar the Indina currency depreciated 5 paise to 74.28 in opening trade on Wednesday as firm American currency and rising crude oil prices weighed on investor sentiment.
At the interbank foreign exchange, the rupee opened at 74.23 against the dollar, then fell further to 74.28, registering a fall of 5 paise over its previous close.

"The obvious risk for the rupee is increasing COVID-19 delta variant cases, which continues to lend support to the greenback and could weigh on sentiments back home," Reliance Securities said in a research note.
Moreover, Asian currencies have started flat to marginally weaker against the greenback this Wednesday morning and could also weigh on the local unit, the note added.
Global oil benchmark Brent crude futures rose 0.41 per cent to USD 75.07 per barrel.
Meanwhile, the dollar index, which gauges the greenback's strength against a basket of six currencies, was unchanged at 92.05.
