<h1>Rupee-dollar exchange rate falls for fourth session to 90.28, despite higher forex reserves and lower oil prices</h1> The rupee depreciated for a fourth consecutive session, closing 8 paise weaker at 90.28 per US dollar in interbank foreign exchange trading after touching an intraday low of 90.50. The reported movement reflects market-driven exchange-rate adjustment under the foreign exchange regulatory framework, attributed to heightened global dollar demand amid geopolitical developments, with partial offset from lower crude oil prices and recent foreign portfolio inflows. RBI foreign exchange reserve data released earlier indicated an increase in reserves to USD 696.61 billion for the week ended December 26, which may support market confidence and liquidity conditions but did not prevent the reported depreciation in the session.
