NEW DELHI: Both houses of India`s parliament were adjourned on Friday amid chaotic scenes as some lawmakers demanded an inquiry following the meltdown of shares in billionaire Gautam Adani`s group companies, which some fear could spark wider financial turmoil.

Shares in Adani companies recovered after sharp falls earlier in the day, but the seven listed firms have still lost about half their market value or more than $100 billion combined since US short-seller Hindenburg Research last week accused the group of stock manipulation and unsustainable debt.

Adani Group, one of India`s top conglomerates, has rejected the criticism and denied wrongdoing in detailed rebuttals, but that has failed to arrest the unabated fall in its shares.

For Adani, a former school drop-outfrom Gujarat, the western home state of Indian Prime Minister Narendra Modi, the crisis presents the biggest reputational and business challenge of his life, as his firm struggles to assuage investor concerns.

Credit ratings agency Moody`s warned on Friday the share plunge could hit the group`s ability to raise capital, although peer Fitch saw no immediate impact on its ratings.

`These adverse developments are likely to reduce the groups ability to raise capital to fund committed capex or refinance maturing debt over the next 1-2 years. We recognise that a portion of the capex is deferrable,` Moody`s said.

Amid fears the turmoil could spill over into the broader financial system, some Indian politicians have called for a wider investigation into the matter, and sources said the centralbankhasaskedlendersfordetailsofexposuretothegroup.

The speakers of both houses of parliament adjourned proceedings on Friday as some lawmakers disrupted business by shouting slogans such as: `We want a joint parliamentary committee (to investigate)` and `Stop looting the poor!` On Thursday, S&P Dow Jones Indices said it would drop the conglomerate`s flagship Adani Enterprises from widely used sustainability indexes on Feb 7, which would blunt their appeal for environment-conscious investors.

`Contagion concerns are widening, but still limited to the banl(ing sector,` said Charu Chanana, a market strategist with Saxo Markets in Singapore. `One of the big risk factors to watch for now is if more indices remove Adani stocks ... This can result in foreign outfiows as funds sell Adani stocks, further aggravat-ing confidence issues,` Chanana said.

Adani Enterprises shares closed 1.4pc higher, after earlier slumping 35pc to hit their lowest since March 2021 during trade. That low took its losses to nearly $33.6 billion since last week, for a decline of 70pc.

Adani Ports and Special Economic Zone Ltd was up 8pc, while Adani Transmission Ltd and Adani Green Energy Ltd were both down 10pc.

Adani Total Gas Ltd , a joint venture with France`s TotalEnergies SE, fell5%. In a statement, TotalEnergies said it had limited exposure to stakes in Adani companies and had not re-evaluated them.

India`s divestment secretary Tuhin Kanta Pandey said that shareholders and customers of state-run Life Insurance Corp (LIC) should not be concerned about its exposure to Adani group. LIC holds a 4.23pcstake in the flagship Adani firm, while its other exposures include a 9.14pc stake in Adani Ports and 5.96pc in Adani Total Gas.

Adani, 60, has in recent years forged partnerships with, and attracted investment from, foreign giants as he pursued global expansion in industries from ports to power.

The market and financial crisis means foreign investors, many already underweight on India as they consider its stock marl(et overpriced, are reducing exposure.

Asl(ed about recent stock market weal(ness, India`s finance minister Nirmala Sitharaman told Network18 that `one instance, however much talked about globally it may be, I would think is not going to be indicative of how well Indian financial markets are governed.

In its report, Hindenburg said keylisted Adani companies had `substantial debt` and shares in the seven listed firms had a downside of 85pc due to what it called sky-high valuations. It also alleged stock manipulation.

The Adani group said the allegation of stock manipulation had `no basis` and stemmed fromignorance of Indian law. It added that over the past decade, group companies have `consistently de-levered`.

The listed Adani firms now have a combined marlcet value of $107.5 billion, versus $218 billion before Hindenburg`s report. The plunge has forced Adani to cede the crown of Asia`s richest person to Indian rival Mukesh Ambani of Reliance Industries Ltd, as he has slid to 17th in Forbes` ranking of the world`s wealthiest people.
