Mumbai, Sep 22 (IANS): The Indian rupee has depreciated to the record low since the morning trade after the dollar index surged to 20-year high and 75 basis points rate hike by the US Fed, and hint at more rate hikes in the future.

Rupee's previous record low against the greenback was 80.12 reached late in August.

At the interbank foreign exchange market at 12.30 p.m., rupee was trading at 80.71 against the dollar, which was sharply lower than its previous close.

"With the US Fed increasing rates by 75 bps and hinting at more rate hikes in the future, we believe the dollar index can see a significant increase, implying that most major market currencies, including INR should be under pressure. If we start seeing INR depreciating, then from a USD returns perspective for FPIs, India becomes unattractive," said Naveen Kulkarni, Chief Investment Officer, Axis Securities PMS.

The US dollar index hit a fresh 20-year high on Thursday after the US Fed warned about aggressive rate hikes in the future. The dollar index jumped to 111.530 on Thursday during the afternoon trade.

The local currency as well as dollar index also got hurt due to escalating geopolitical tensions after Russia ordered a partial mobilisation of military forces in Ukraine.

Kulkarni also added that we could also witness a reversal of FPI flows in the near to medium term, which will increase market volatility. Higher interest rates in the US will force major central banks, including India, to increase interest rates to stem the pressure on their domestic currencies and with increased interest rates and cost of capital, market multiples can contract. We believe in the near term, Indian equity markets can witness increased volatility.

Kunal Sodhani, Vice President, Global Trading Center, Shinhan Bank in a note said that considering the technical charts DXY can test 112.50, EURUSD can test 0.9720/50 levels, GBPUSD can test 1.1180 levels, USDJPY can test 145.20 levels.

"For USDINR, 79.60 acts as a good base while a break of all-time high of 80.13 on a closing basis, can open doors for 80.50 levels as a lot of option sellers may trigger stop losses," Sodhani added.

After the rate hike by the US Fed, overseas stocks tumbled which was followed by domestic equities. At 12.30 p.m., Sensex was down 608.78 points or 1.02 per cent at 58,848.00 and Nifty was 165.75 points or 0.94 per cent at 17,532.95.
