__________________________________________________________________________



*    HSBC USA Inc.'s primary subsidiary is HSBC Bank USA, National Association
(the Bank), which is subject to supervision and examination by various U.S.
regulators.  The Bank was required to file periodic financial information (Call
Report) for the year ending 31 December 2005 and this information is publicly
available through U.S. government information resources.  Given that this
information is available in the public domain, HSBC USA Inc has elected to file
this release.



**   Results are prepared in accordance with U.S. GAAP (generally accepted
accounting principles). HSBC USA Inc. is an indirect wholly-owned subsidiary of
HSBC Holdings plc (HSBC). HSBC's 2005 results are scheduled for release on 6
March 2006. Those results will be released under International Financial
Reporting Standards (IFRS) and will describe HSBC's North American results,
including HSBC USA Inc. and HSBC Finance Corporation, as well as HSBC's fully
consolidated figures. Certain revenues and expenses related to inter-HSBC
transactions are eliminated upon consolidation. See *** below.



***  The purchase of consumer finance assets, principally credit card
receivables from prime customers, included an initial purchase premium of US$639
million. US$451 million of this initial purchase premium was amortized as a
reduction to revenues in 2005. In addition, 2004 results included gains from the
sale of credit card relationships to HSBC Finance Corporation of approximately
US$99 million. As part of the HSBC consolidation process, the amortization of
US$451 million and the US$99 million gain are eliminated.








HSBC USA Inc. reported net income of US$976 million for the year ended 31
December 2005, compared to US$1,258 million for the year ended 31 December 2004.
The reduction in pre-tax income from 2004 to 2005 of US$434 million includes two
meaningful inter-HSBC accounting events, both of which are eliminated upon
consolidation.  US$451 million of pre-tax premium amortization costs were
recorded in 2005 on the private label credit card portfolio purchased from HSBC
Finance Corporation at year-end 2004. Also, 2004 results included gains from the
sale of credit card relationships to HSBC Finance Corporation of approximately
US$99 million. These transactions comprise the most significant factors in the
year-to-year reduction in pre-tax income.  The addition of the private label
credit card portfolio significantly increased year-over-year revenues,
provisions for credit losses, and operating expenses.



Commenting on the results, Martin Glynn, President and Chief Executive Officer
of HSBC USA Inc. said: "Results in 2005 were generally strong and surpassed
expectations, due in part to a sound economy which led to very strong credit
quality, particularly within our commercial lending portfolios. Strong revenue,
loan, and deposit growth were also recorded within our core banking businesses,
including Personal Financial Services, Commercial Banking and Private Banking.
We were especially proud of the growth achieved with our small business
customers as we were named the No. 1 Small Business Administration lender in New
York State.



"Within North America, numerous initiatives are underway amongst the various
HSBC affiliates. One of these involved the transfer of consumer finance assets,
principally credit cards, from HSBC Finance Corporation to HSBC USA Inc. in late
2004 in order to realize funding benefits. The non-cash accounting amortization
of the associated purchase premiums reduced reported results in HSBC USA Inc. in
2005. Looking forward, this amortization reduces significantly in 2006 and I
anticipate this portfolio will contribute positively in the years ahead.



"We invested in our Corporate Investment Banking and Markets (CIBM) capabilities
over the past two years as part of HSBC's strategic initiative to build this
business. While this increased our expense base in 2005, it was gratifying to
see a commensurate increase in trading revenues, which were up 37 per cent year
over year. However, the flat yield curve did significantly constrain our growth
in net interest income, particularly in the second half of the year.



"Our focus for 2006 will be to maintain strong revenue growth and increasingly
leverage marketing initiatives to heighten awareness of the HSBC brand in the
U.S. The national rollout of our Online Savings Account product offered at
www.hsbcdirect.com is an example of such an effort to drive growth of the brand
and add deposits. HSBC USA Inc. is well positioned to support the future
financial requirements of our customers and generate increasingly positive
financial results."



Revenues

For the year ended 31 December 2005, total revenues (pre-provision) increased by
US$914 million, or 23 per cent, from US$4,060 million to US$4,974 million. The
acquisition of the consumer finance assets, primarily the credit card portfolio,
contributed largely to the increases (notwithstanding the premium amortization
discussed above) in net interest income and in fee income (including both credit
card and securitization fees).

Trading revenues increased 37 per cent compared with 2004, primarily in the CIBM
businesses, driven partly by investment in HSBC's strategic expansion initiative
and partly by favorable capital market conditions. These increases partially
offset the effect of the flat yield curve, which significantly constrained HSBC
USA Inc.'s ability to generate growth in net interest income, particularly in
the second half of the year.

Growing levels of deposits in core banking businesses also contributed to
increased revenues by providing lower cost funding to support asset growth.
Residential mortgage banking revenue, including servicing fees net of
impairment, origination gains, and related hedge costs, improved significantly
over 2004.

Operating Expenses

For the year ended 31 December 2005, operating expenses increased by US$657
million, or 31 per cent, from US$2,101 million to US$2,758 million, which
included a significant increase in support services received from HSBC
affiliates, particularly in the fourth quarter. These include support from HSBC
Finance Corporation (loan origination and servicing), HSBC Technology Services
(information and technology services), and HSBC Markets USA (broker-dealer and
support for CIBM). In addition, increased expenses were incurred for marketing
and brand expansion initiatives, as well as expansion of retail lending and
deposit activities through new products and new offices outside of New York
State.



Credit Quality and Provisions for Credit Losses

For the year ended 31 December 2005, the provision for credit losses increased
by US$691 million to US$674 million, primarily related to growth in the consumer
lending portfolios. The increase is mainly related to the credit card portfolio
acquisition, but also reflects increases due to the impact of Hurricane Katrina
and the changes in consumer bankruptcy laws. The commercial lending provision
was lower than in 2004, reflecting the continued improvement in credit quality
during 2005. Net charge-offs of US$616 million for the year ended 31 December
2005 were primarily related to consumer loans.



Capital Ratios

HSBC USA Inc.'s tier 1 capital to risk-weighted assets ratio was 8.25 per cent
on 31 December 2005 compared to 8.34 per cent at 31 December 2004. Total capital
to risk-weighted assets of 12.53 per cent on 31 December 2005 was unchanged
compared to 31 December 2004.
