Mild dollar selling by banks and exporters in the face of subdued overseas sentiment alongside a smart recovery in equities largely supported the domestic currency, which struggled to stay positive.
Meanwhile, domestic equities snapped a two-day losing streak and staged a smart rebound on value-buying alongside some short-covering despite lacklustre Asian cues.
The domestic unit opened on a strong footing at 68.08 from Monday's closing value of 68.21 at the Interbank Foreign Exchange (Forex) market on fresh bouts of dollar selling and gained further ground to touch an intra-day high of 67.98 in late morning deals.
It had tumbled by 25 paise yesterday.
