The rupee sank 30 paise to close below the 70-mark against the US currency due to renewed worries about a hike in US interest rates amid global trade war jitters.

The domestic currency ended at 70.11 a dollar, a loss of 30 paise or 0.43 per cent over the previous close. In day trade, the rupee had crumbled to a session-low of 70.17 per dollar.

The rupee suffered its the biggest single-day drop in the past one week, snapping a two session recovery. Forex sentiment wobbled with a resurgent dollar as currency traders increased their expectations for a fourth interest rate hike this year after the Fed released its meeting minutes overnight.
