Tata Consultancy Services (TCS) and Infosys have the highest exposure to regional banks in the US that are gripped by a financial turmoil, analysts at JP Morgan said on Friday.

Regional banks in the US account for 2-3 per cent of their revenue, JP Morgan said in a note, adding that the exposure to the recently collapsed Silicon Valley Bank could be 10-20 basis points for TCS, Infosys and smaller rival LTIMindtree, with the Tata group company in the lead.

All three companies might need to set aside provisions in the fourth quarter due to their exposure to SVB, JP Morgan said in a note.

"The collapse of SVB, Signature Bank and concerns of liquidity across US and the European Union can further soften tech spends by banks over the short term in a year with slowing growth in bank tech budgets," JP Morgan, which has an "underweight" rating on the sector, said.

India's IT industry is already facing a challenging macroeconomic environment in its key markets of Europe and the US, where technology spending is contracting amid delays in decision-making on long-term deals as the pandemic-led surge in demand faded.

The banking crisis could delay deal ramp-ups, impacting revenue conversions over the next two quarters, and push back new order closures that could hurt revenue over the next four quarters, JP Morgan said.

Indian IT firms draw the bulk of their revenue from the banking, financial services and insurance (BFSI) sector.

Within BFSI, their exposure to the US banks is on average 62 per cent and Europe 23 per cent, JP Morgan said.

LTIMindtree this week said it had negligible exposure to US regional banks, including SVB.
