Non-deliverable forwards indicate the rupee will open at around 83.20-83.22 to the U.S. dollar compared with 82.95 in the previous session. The rupee's record low is 83.29, reached in October 2022.

India forex and money markets were off on Tuesday and Wednesday. On both these days, the 1-month USD/INR NDF had climbed above 82.50, implying a spot rate that was higher than 83.29.

The Reserve Bank of India possibly intervened in offshore NDF to defend the rupee.

There was "a very high probability" that RBI would "make itself known" at open to keep rupee from making a lifetime low, a forex trader at a bank said.

A decline below 83.30 for the rupee "would trigger a new round" of dollar buying and "you can expect a sizeable move", he said.

The 10-year U.S. yield on Wednesday closed at the highest level since 2008, lifting the dollar index to near 103.50. Resilient U.S. economic data and worries over supply have been among the reasons cited by analysts for the jump in U.S. yields.

The minutes of the U.S. Federal Reserve July meeting out Wednesday showed that policymakers remain highly attentive to inflation risk, providing another reason to investors to avoid U.S. bonds.

Most Fed officials "continued to see significant upside risks to inflation which could require further tightening of monetary policy", the minutes showed.

"The Fed kept the door open for the second hike it pencilled in June at the remaining three meetings of 2023," DBS Research said in a note.

Asian currencies extended losses. The offshore Chinese yuan dropped to almost 7.35 in Asia trading, the lowest since November 2022.
