The following is the text of an announcement submitted to the Stock Exchange of
Hong Kong Limited on 3 December 2007.

The Stock Exchange of Hong Kong Limited takes no responsibility for the contents
of this announcement, makes no representation as to its accuracy or completeness
and expressly disclaims any liability whatsoever for any loss howsoever arising
from or in reliance upon the whole or any part of the contents of this
announcement. The ordinary shares of HSBC trade under stock code 5 on The Stock
Exchange of Hong Kong Limited.

WAIVER OF CERTAIN REQUIREMENTS OF THE LISTING RULES TO ENABLE HSBC HOLDINGS PLC
   TO PUBLISH PRICE-SENSITIVE INFORMATION DURING BUSINESS HOURS IN HONG KONG

The Stock Exchange has granted a conditional waiver to the Company in respect of
Rule 2.07C(4) to allow the Company to publish announcements pursuant to Rule
13.09(1) during the hours of 9:00am to 4:15pm on a business day in Hong Kong
when a conflict exists with Rule 2 of the UK Disclosure and Transparency Rules
(the "Waiver"). The Company may, with effect from today, release an announcement
in the circumstances covered by the Waiver (i) at any time during trading hours
without a subsequent suspension of dealings or trading halt in the Company's
securities; and (ii) during the morning window for the submission of
announcements under the Stock Exchange's electronic publication system of 6.00
a.m. to 9.00 a.m. without being subject to the requirement for suspension in the
morning trading session. As a consequence of the Waiver, price-sensitive
information can now be published by the Company during trading hours in Hong
Kong and no suspension of trading will be required.

The Waiver was sought by the Company because compliance with the UK Disclosure
and Transparency Rules could require an announcement of inside information to be
made by the Company outside the permitted periods for submitting announcements
to the Stock Exchange for publication on its website under the Listing Rules,
which may require the Company's shares to be suspended from trading in Hong
Kong.

The impact of the Waiver for investors in Hong Kong is that trading in the
Company's securities will continue in the event that an announcement containing
price-sensitive information is released by the Company during trading hours in
Hong Kong. As a result, investors in Hong Kong should consider whether any
price-sensitive information has been released during trading hours in Hong Kong
prior to making an investment decision regarding the Company's securities.
Investors can access announcements released by the Company (including those
containing price-sensitive information) via the Stock Exchange's website at
www.hkex.com.hk. Announcements will also be published on the Company's website
at www.hsbc.com in accordance with the Listing Rules.  The Listing Rules require
that, where an announcement is submitted to the Stock Exchange for publication
on its website during trading hours, publication on the Company's own website
must be no later than one hour after such submission.

The Waiver is subject to certain conditions. In particular, the Company will
inform the Stock Exchange promptly in the event of any material change made to
the UK regime relating to the disclosure of inside information, and will make a
further announcement if the terms of the Waiver are materially affected by any
such change. The Stock Exchange has reserved its right to evaluate any such
changes to the UK regime and may amend or revoke the Waiver as it sees
appropriate.

The Waiver

The Stock Exchange has granted a conditional waiver to the Company in respect of
Rule 2.07C(4) to allow the Company to publish announcements pursuant to Rule
13.09(1) during the hours of 9:00am to 4:15pm on a business day in Hong Kong
when a conflict exists with Rule 2 of the UK Disclosure and Transparency Rules
(the "Waiver"). The Company may, with effect from today, release an announcement
in the circumstances covered by the Waiver (i) at any time during trading hours
without a subsequent suspension of dealings or trading halt in the Company's
securities; and (ii) during the morning window for the submission of
announcements under the Stock Exchange's electronic publication system of 6.00
a.m. to 9.00 a.m. without being subject to the requirement for suspension in the
morning trading session. As a consequence of the Waiver, price-sensitive
information can now be published by the Company during trading hours in Hong
Kong and no suspension of trading will be required.

The Company has a dual primary listing of its securities on The Stock Exchange
of Hong Kong Limited and the Official List in the UK (its shares being admitted
to trading on the Main Market of the London Stock Exchange). As a result, the
Company is subject to the applicable legal and regulatory requirements under
both jurisdictions. The Waiver was sought by the Company because compliance with
the UK Disclosure and Transparency Rules could require an announcement of inside
information to be made by the Company outside the permitted periods for
submitting announcements to the Stock Exchange for publication on its website
under the Listing Rules, which may require the Company's shares to be suspended
from trading in Hong Kong.

Rationale behind the Waiver application

Under Rule 13.09(1), the Company is required to announce information in Hong
Kong which, inter alia, is necessary to avoid the establishment of a false
market in its securities or which might materially affect the price of its
securities ("price-sensitive information"). Rule 2.07C(4) requires that, except
in certain limited circumstances, an announcement must be made outside normal
trading hours (i.e. the announcement must not be submitted to the Stock Exchange
for publication between 9:00am and 4:15pm on a business day in Hong Kong). In
the event such an announcement is released on a separate market during normal
trading hours in Hong Kong, the Stock Exchange would usually seek to suspend the
securities of the relevant listed issuer, pending the appropriate publication of
the price-sensitive information in accordance with the Listing Rules.

The provisions of the Listing Rules are different from the UK Disclosure and
Transparency Rules which require the release of inside information to the market
as soon as possible regardless of whether such announcement is made during
normal trading hours. ("Inside information" is broadly similar to the concept of
"price-sensitive information" under the Listing Rules and includes information
in relation to the Company's shares and other investments which is precise, not
generally available and would, if generally available, be likely to have a
significant effect on the price of the shares or other investments.)

If an announcement is made pursuant to the UK Disclosure and Transparency Rules
in relation to inside information, no suspension of the Company's securities
would generally be imposed by the London Stock Exchange or the UKLA. The
directors of the Company consider that a suspension of the Company's securities
in Hong Kong in these circumstances could give rise to misunderstandings and
adverse consequences in relation to the securities of the Company in different
markets and jurisdictions where suspension is not so frequent.

Prior to the grant of the Waiver, the Company was in the position that
compliance with the UK Disclosure and Transparency Rules could result in
non-compliance with the requirements of the Listing Rules. Without the Waiver,
the Company may have been required to issue announcements under the UK
Disclosure and Transparency Rules and suspend trading in the Company's
securities on the Stock Exchange in Hong Kong. This would potentially put Hong
Kong investors at a disadvantage compared to other investors, since other
investors may be able to deal in the Company's securities on the other exchanges
on which they are listed or traded whilst Hong Kong investors are prevented from
doing so. As a result, the Company sought and received the Waiver.

The Stock Exchange has also agreed to modify the application of note 5 to Rule
13.09(1), Rule 13.10 and Rule 14.37 (to the extent they apply to the Company) to
reflect the terms of the Waiver as explained in this Announcement and has agreed
to allow the Company to publish announcements pursuant to Rule 13.09(1) during
the morning window of the electronic publication system of 6 a.m. to 9.00 a.m.
without the requirement for suspension in the morning trading session. Provided
an announcement is released in accordance with the Waiver, the Stock Exchange
has confirmed that the Company's obligations under Rule 13.09(1) are considered
discharged upon timely publication of such announcement and no suspension of
trading will be required.

Impact of the Waiver

The impact of the Waiver for investors in Hong Kong is that trading in the
Company's securities will continue in the event that an announcement containing
price-sensitive information is released by the Company during trading hours in
Hong Kong. As a result, investors in Hong Kong should consider whether any
price-sensitive information has been released during trading hours in Hong Kong
prior to making an investment decision regarding the Company's securities.
Investors can access announcements released by the Company (including those
containing price-sensitive information) via the Stock Exchange's website at
www.hkex.com.hk. Announcements will also be published on the Company's website
at www.hsbc.com in accordance with the Listing Rules.  The Listing Rules require
that, where an announcement is submitted to the Stock Exchange for publication
on its website during trading hours, publication on the Company's own website
must be no later than one hour after such submission.

Conditions of the Waiver

The Waiver is subject to the following conditions:

(a)  the Company making this announcement;

(b)  the  Company  informing  the Stock  Exchange  promptly  in the event of any
     material  change being made to the UK regime  relating to the disclosure of
     inside  information.  The Company will make a further  announcement  if the
     terms of the Waiver are materially  affected by any such change.  The Stock
     Exchange  has  reserved  its right to evaluate  any such  changes to the UK
     regime and may amend or revoke the Waiver as it sees appropriate; and

(c)  the Company complying with the relevant  provisions in the event of changes
     to the Hong Kong regulatory regime and the Listing Rules in relation to the
     disclosure  of   price-sensitive   information  and  the  Stock  Exchange's
     'Electronic  Disclosure  Project',  unless the Stock Exchange has agreed to
     amend the Waiver or grant a new Waiver to the Company.

The Waiver has been granted by the Stock Exchange on the understanding that the
Directors of the Company are aware of their obligations under the Listing Rules
for the maintenance of an orderly market in the Company's securities and would
be guided by Practice Note 11 of the Listing Rules if there was a leak of
price-sensitive information, if price-sensitive information could not be
disclosed, or if it would be appropriate to issue a 'warning' announcement.
Further, the Waiver has been granted by the Stock Exchange in the expectation
that the Company will manage its affairs in a timely manner, particularly with
regard to the signing of agreements, to ensure there will be a continuous
trading in its securities on the Stock Exchange save in exceptional
circumstances.

The Company has confirmed to the Stock Exchange that all announcements made
pursuant to Rule 13.09(1) will be made simultaneously in English and Chinese.
The Stock Exchange has requested that, to ensure the smooth publication of
announcements made pursuant to the Waiver, the Company is required to notify the
Stock Exchange of pending announcements and the expected times of release and
submit the electronic copies of the English and Chinese versions of such
announcements at least 10 minutes in advance of the expected times of release.

A copy of this Announcement will be posted on the Company's website at
www.hsbc.com and on the Stock Exchange's website at www.hkex.com.hk.
