Here's what is weighing on the market:
Banking, financial stocks tumble on Irdai's proposed norms
JM Financial has flagged potential implications for select banks and non-banking financial companies (NBFCs) from Irdai's proposed distribution reforms.
The insurance regulator's consultation paper proposes lower Expenses of Management (EOM) caps for life and general insurers, along with segment-level commission caps that were eliminated from FY24. The draft also includes specific observations on the bancassurance channel.
Among banks, JM Financial's assessment of disclosures shows that Ujjivan Small Finance Bank Ltd, AU Small Finance Bank Ltd, IDFC First Bank Ltd, Bandhan Bank Ltd, DCB Bank Ltd and Axis Bank Ltd have a relatively higher contribution from insurance fee income.
In the NBFC segment, L&T Finance Ltd, Home First Finance Company India Ltd, Cholamandalam Investment and Finance Company Ltd, Bajaj Finance Ltd, Aadhar Housing Finance Ltd, Mahindra & Mahindra Financial Services Ltd and HDB Financial Services Ltd have a higher contribution from insurance fee income, JM Financial said.
Rising crude oil prices, US yields
VK Vijayakumar, Chief Investment Strategist at Geojit Investments, said the sharp rise in Brent crude oil prices towards $106 a barrel and the increase in the US 10-year bond yield were weighing on the market.
"As long as these two global headwinds remain, the prospects of a smart recovery in the market appear remote," Vijayakumar said.
Global market cues
Devarsh Vakil, Head of Prime Research at HDFC Securities, said the US 10-year Treasury yield has risen to its highest level since 2007. "US equities fell sharply, snapping record runs, as the 10-year Treasury yield broke above 5 per cent," he also said.
At last check, the US 10-year Treasury yield was around 5.13 per cent, while the two-year yield stood at around 4.89 per cent.
Vakil added that global sentiment had weakened after Wall Street ended lower amid rising US Treasury yields and an increase in the Dollar Index, putting pressure on emerging-market sentiment.
"Renewed uncertainty surrounding the US-Iran conflict has also contributed to risk aversion," he further said.
