But company says third-quarter operating income up from year-ago period, boosted by revenue growth.
HSBC Holdings PLC said Wednesday it was taking a $3.4 billion charge against third-quarter profits because of accelerating losses in its HSBC Finance Corp. mortgage business in the United States.
However, in a trading update the company said that those losses were "more than offset by revenue growth in the group" as a whole and that third-quarter operating income was up compared with a year ago.
There is the probability of further deterioration if the current housing market distress continues and further impacts the broader economy, the company said.
Shares in HSBC gained 4 percent to 877 pence ($18.11) on the London Stock Exchange.

UK banking giant HSBC has declined to comment on speculation its US unit will this week reveal a further $1bn (£478m) exposure to bad American housing debt.
HSBC Finance will show the losses when it releases results on Wednesday for the three months to the end of September, said the Sunday Telegraph.
The unit has already cut 750 jobs at a cost of $945m (£452m) due to the crisis in the US sub-prime mortgage sector.
The job losses came as it shut down one of its sub-prime mortgage subsidiaries.
That announcement was made back in September.
Barclays denial
Sub-prime mortgages are higher risk home loans to people with poor credit histories, or those on low incomes.
The sector has experienced record loan defaults against a backdrop of higher US mortgage rates over the past year.
The knock-on effect has been large losses for many of Americas biggest banks, who found themselves heavily exposed to the industry.
Two of the largest - Citigroup and Merrill Lynch - have both seen their former bosses resign as a result.
HSBCs fellow UK bank Barclays denied on Friday that it was about to reveal a $10bn exposure to US mortgage bad debt.
Last Week, Fourth largest lender Wachovia sparked the latest share falls after it said its losses on bad mortgage debt would total $1.1bn (£525m) for October alone.
