The rupee breached the 90-a-dollar level for the first time to settle at a fresh all-time low of 90.21 (provisional) on Wednesday, down 25 paise from its previous close, amid sustained foreign fund outflows and higher crude oil prices.

Uncertainty over the India-US trade deal, along with the lack of Reserve Bank of India (RBI) effort to stop the slide in the local unit, put further pressure on the rupee, according to forex traders.
