HSBC, Europe's largest bank, said on Monday its its third-quarter reported pre-tax profit jumped 28 percent from a year ago to $5.922 billion.

The bank's revenue for the July-to-September quarter was $13.798 billion, 6.32 percent higher than the same period a year ago.

Despite those improvements, the bank's reported pre-tax profit and revenue for the quarter slightly missed expectations, according to analyst forecasts compiled by data firm Refinitiv.

Other key financial metrics that analysts were watching:

Adjusted profit before tax was $6.193 billion in the third quarter, 16 percent higher than the same period a year ago.

Net interest margin, a measure of lending profitability, was at 1.67 percent as of Sept. 30, HSBC said. That's higher than the 1.63 percent seen a year ago.

Operating expenses for the quarter were $7.966 billion, down from $8.546 billion in the period from July to September in 2017.

"These are encouraging results that demonstrate the revenue potential of HSBC," the bank's group chief executive, John Flint, said in a statement accompanying the earnings release.

HSBC's Hong Kong-listed shares jumped 5 percent after the lunch break. Its shares in both London and Hong Kong have fallen by more than 20 percent since the start of the year as global growth prospects are increasingly threatened by uncertainties surrounding trade.
