India’s rupee may weaken to a record 100 per dollar or beyond if the Iran war drags on, with strategists warning that authorities’ efforts to slow its roughly 10% drop over the past year may only provide temporary relief. Analysts at Wells Fargo and Van Eck Associates Corp. say elevated oil prices will accelerate the rupee’s decline by worsening inflation and the current-account deficit. Options markets echo that view, with pricing suggesting further losses and signaling expectations of a move toward 100.
