TORONTO, Aug 27 (Reuters) - Bank of Montreal ( BERZ ) on

Tuesday warned it would need to continue to set aside money for

loans that are unlikely to be repaid, after the Canadian lender

reported lower-than-expected profit for the sixth time in a row.

The lender however said it would start to see a recovery in

2025 as central banks cut interest rates and unemployment

stabilizes which would ease some pressure for consumers and

businesses falling behind on their loan repayments.

Third-quarter loan loss provisions were higher than analysts

had forecast, in part due to impaired provisions for two

customers, one in the U.S. and one recorded under its Capital

Markets business.

"We've investigated the circumstances that led to recent

impairments, and the conclusion is, for some customers, the

combination of prolonged high interest rates, economic

uncertainty and changing consumer preferences had an acute

impact," BMO's CEO Darryl White told analysts.

Fifteen accounts drove about half of the year to date

impaired provisions in its wholesale portfolio, White said.

Chief Risk Officer Piyush Agrawal said the increase in loss

provisions in the retail sector was "systemic" and in wholesale,

he said it was not "thematic to a sector".

"I'm confident we've looked through our files," he said

about the bank's loans to larger clients or companies.

Meanwhile, peer Bank of Nova Scotia,, Canada's

fourth largest bank by market capitalization, reported better

than expected profit powered by strong growth at its businesses

at home and overseas, which spans across North America, Latin

America and the Caribbean.

BMO's shares sank 6% in early trading in Toronto, while

those of Scotiabank rose about 2.5%.

Canadian banks have sought growth south of the border

expanding through acquisitions or brick by brick as

opportunities in a saturated an highly regulated market at home

were limited.

BMO purchased U.S. regional lender Bank of the West for

$16.3 billion last year, while Scotiabank looked further down,

expanding in largely underbanked areas in South America and

Latin America, focusing on the Pacific Alliance trade bloc.

Scotiabank is now betting on the $1.6 trillion North

American trade, concentrating on Mexico, and U.S. Most recently,

Scotiabank invested $2.8 billion in U.S. regional bank KeyCorp ( KEY ),

its first exposure to the region.

But BMO and other Canadian banks that have a U.S. presence

have faced many challenges in a competitive U.S. banking market,

forcing them to spend more to retain deposits and boost loan

growth.

BMO, Canada's third-largest lender, said provision for

credit losses jumped to C$906 million ($672.8 million) in the

third quarter, from C$492 million a year earlier. Analysts were

expecting C$734 million, according to LSEG data.

"The weakness was widespread with all segments showing some

deterioration," TD Securities analyst Mario Mendonca wrote in a

note.

Adjusted net income at its U.S. personal and commercial

banking segment fell 7%. Overall, adjusted net income fell to

C$1.98 billion, a 7.8% decline from a year earlier.

BMO earned C$2.64 per share, compared with analysts'

expectations of C$2.76.

Scotiabank booked a 0.7% fall in adjusted income to C$2.19

billion and earned C$1.63 per share, 1 Canadian cent more than

estimates.

"The stability in earnings shown in its International

operations should generate some support," Jefferies analyst

John Aiken said.
