Exhibit 99.1

State Street Third-Quarter Earnings Per Share Increase 64% to $1.08 from $0.66 in the Third Quarter of 2009 on a 3% Increase in Revenue

Operating-Basis Earnings Per Share of $0.86 Increase 21% from $0.71 in the Third Quarter of 2009

Operating-Basis Revenue Increases 8% from Third Quarter of 2009 Driven Primarily by Increase in Servicing Fee Revenue

BOSTON--(BUSINESS WIRE)--October 19, 2010--State Street Corporation today announced third-quarter 2010 earnings per common share of $1.08, an increase of 64% compared to $0.66 in the third quarter of 2009. Revenue in the third quarter of 2010 was $2.310 billion, up 3% from $2.236 billion in the third quarter of 2009. Expenses of $1.527 billion in the third quarter declined 12% from $1.733 billion in the third quarter of 2009. Return on shareholders’ equity was 12.9%, up from 10.2% in the third quarter of 2009.

Compared to the second quarter of 2010, third quarter 2010 earnings per share increased 24% from $0.87 per share and revenue was up slightly from $2.304 billion. Expenses in the second quarter of 2010 were $1.944 billion including the previously disclosed securities finance charge. For the second quarter of 2010, return on shareholders’ equity was 11.0%.

In addition to presenting State Street’s financial results in conformity with U.S. generally accepted accounting principles (GAAP), management also presents results on an “operating basis” in order to highlight comparable financial trends and other characteristics with respect to State Street’s ongoing business operations from period to period. Reconciliations of GAAP-basis results to operating-basis results are provided in the addendum at the end of this news release. Also see “Additional Information.” Operating-basis net interest revenue for all periods is presented on a fully taxable-equivalent basis and excludes discount accretion related to former conduit assets.

Operating-basis earnings per share in the third quarter of 2010 were $0.86 compared to $0.71 in the third quarter of 2009 and $0.93 in the second quarter of 2010. Operating-basis revenue in the third quarter of 2010 was $2.154 billion, up 8.4% from $1.988 billion in the third quarter of 2009 and down 0.4% from $2.163 billion in the second quarter of 2010. Operating-basis expenses increased to $1.518 billion in the third quarter of 2010, up 3.1% from $1.472 billion in the third quarter of 2009 and up 3.4% from $1.468 billion in the second quarter of 2010. On an operating basis, return on equity of 10.2% in the third quarter of 2010 compared with 11.0% in the third quarter of 2009 and 11.8% in the second quarter of 2010.

Joseph L. Hooley, State Street's president and chief executive officer, said, “In the third quarter, our overall results were driven by strength in our servicing fee revenue, and our ability to maintain our focus on cost control. During the third quarter, we won $477 billion in assets to be serviced. State Street Global Advisors continues to perform well although management fees were down slightly, due primarily to the change in business mix as shown in assets under management. The integrations of the Intesa and Mourant businesses are progressing well and are on track to meet the outlook we previously provided. The weak, low-volume trading environment continues to be challenging for our trading services business. Although the low level of interest rates worldwide continues to create headwinds, we achieved a net interest margin of 177 basis points, excluding discount accretion. On a year-over-year operating basis, we achieved 530 basis points of positive operating leverage and continued to manage expenses very carefully. Our capital levels remain strong and are well in excess of the current regulatory well capitalized requirements.”

Hooley continued, “With the support of the two acquisitions, as well as strong year-to-date wins in servicing and growth in passive strategies and ETFs in asset management, we continue to expect that our operating-basis earnings per share, which exclude discount accretion, will be slightly above the adjusted operating-basis $3.32 per share recorded last year.”

Hooley concluded, “We are well positioned to take advantage of global growth opportunities and, as the economy normalizes, we are committed to our long-term financial goals for operating-basis revenue, earnings per share and return on equity.”

The table below provides a summary of selected financial information and key ratios for the indicated periods, presented on an operating basis where noted. Unless otherwise specified, all capital ratios referenced in this news release refer to State Street Corporation and not State Street Bank and Trust Company. See “Additional Information” for a further description of these ratios and the addendum at the end of this news release for reconciliations applicable to the tier 1 common and TCE ratios.

(1) Presented on an operating basis. Operating-basis results for the third quarter of 2009 presented in this news release have been adjusted to reflect the 2010 basis of presentation and therefore exclude discount accretion associated with the May 2009 consolidation of the former asset-backed commercial paper conduits. Consequently, these operating-basis results may differ from previously disclosed operating-basis results for the same period.
(2) Includes assets under custody of $14,860 billion, $13,999 billion, and $13,260 billion, respectively, as of period end Q3 2010, Q2 2010, and Q3 2009.

Total assets were $173 billion at September 30, 2010, including $20 billion in excess deposits held primarily at the Federal Reserve and at other central banks. The average balance sheet for the third quarter was $154 billion, compared to $151 billion for the second quarter of 2010 and $145 billion for the third quarter of 2009. State Street’s regulatory capital ratios continue to be strong as of September 30, 2010, with the Company’s tier 1 capital ratio at 15.8% and its leverage ratio at 8.3%. In addition, at that date, the Company’s tier 1 common ratio was 13.9%, its TCE to risk-weighted assets ratio was 13.3%, and its TCE ratio was 6.9%.

At September 30, 2010, the after-tax, unrealized mark-to-market losses in the investment portfolio were $281 million, down 72% from $994 million at June 30, 2010, and down about 91% from $2.99 billion as of September 30, 2009.

In the third quarter of 2010, discount accretion related to the former conduit assets of $189 million, or $0.23 per share, contributed to State Street’s capital strength, and the Company continues to expect a total of about $750 million of accretion to be recorded in 2010. As of September 30, 2010, the Company expects a pre-tax aggregate of about $3.6 billion to accrete into interest revenue over the remaining lives of the assets. These expectations are based on many assumptions, including holding the securities to maturity, anticipated pre-payment speeds, credit quality, and sales to date.

The following tables provide the components of operating-basis revenue and operating-basis expenses for the noted periods:

⁽¹⁾ Operating-basis information for the third quarter of 2010, the second quarter of 2010, and the third quarter of 2009 included $33 million, $31 million, and $31 million, respectively, of tax-equivalent adjustments, and excluded $189 million, $172 million, and $279 million, respectively, of discount accretion. GAAP-basis net interest revenue for those periods was $724 million, $658 million and $723 million, respectively.

THIRD-QUARTER 2010 RESULTS VS. THE THIRD QUARTER of 2009

Servicing fees were up 19% to $989 million from $833 million in the third quarter of 2009. The increase was attributable primarily to the impact of the acquisition of Intesa Sanpaolo’s securities servicing business (“Intesa”) and Mourant International Finance Administration (“Mourant”), new business, and increases in daily average equity valuations. Total assets under custody and administration were $20.23 trillion at September 30, 2010, up 13% compared with $17.94 trillion at September 30, 2009. Daily average values for the S&P 500 Index were up 10% and the MSCI^® EAFE Index^ES increased approximately 2% from the third quarter of 2009.

Investment management fees, generated by State Street Global Advisors, were $213 million, down 3% from $219 million in the third quarter of 2009. The decrease in management fees was attributable primarily to the mix of business reflected in assets under management, offset partially by increases in the average of month-end valuations in worldwide equity markets. Average month-end equity valuations increased about 7% compare to the third quarter of 2009 as measured by the S & P 500 and were approximately flat as measured by the MSCI EAFE index^ES. Total assets under management at September 30, 2010, were $1.90 trillion, up 10% compared to $1.74 trillion at September 30, 2009.

Trading services revenue, which includes foreign exchange trading revenue and brokerage and other fees, was $228 million for the third quarter of 2010, a decrease of 15% from $269 million in the third quarter of 2009. Foreign exchange revenue decreased 30% primarily due to lower volatility and volumes. Brokerage and other fees were up about 3% due primarily to an increase in electronic trading.

Securities finance revenue was $68 million in the quarter, down 35% from $105 million in the third quarter of 2009 due primarily to compressed spreads and slightly lower volumes. Processing fees and other revenue was $71 million, up from $45 million in the third quarter of 2009 due primarily to increased revenue from structured products.

Net interest revenue on a fully-taxable equivalent basis, which includes discount accretion, was $757 million. On an operating basis, which excludes discount accretion, net interest revenue was $568 million, an increase of 20% from $475 million in the third quarter of 2009 due to higher yields and volumes in the investment portfolio and the full-quarter impact of deposits added in connection with the Intesa acquisition. Net interest margin, including the discount accretion, was 236 basis points in the third quarter of 2010 compared to 247 basis points in the third quarter of 2009. Operating-basis net interest margin was 177 basis points in the third quarter of 2010, compared to 156 basis points in the third quarter of 2009.

In the third quarter of 2010, we recorded $91 million of net gains from sales of available-for-sale securities. Separately, we recorded $(74) million of other-than-temporary impairment, resulting in $17 million of net gains related to investment securities.

Operating-basis expenses of $1.518 billion in the third quarter of 2010 increased 3% compared to $1.472 billion in the third quarter of 2009 primarily due to increases in salaries and benefits expenses, offset partially by a lower level of other expenses. Salaries and benefits expenses increased 6% to $871 million, primarily due to the impact of the acquisitions. Information systems and communications were $181 million, an increase of 10% from $165 million due primarily to the impact of the two acquisitions. Transaction processing services were up 11% to $165 million due to higher volumes in the investment servicing business including the impact of the two acquisitions. Other expenses decreased 15% to $189 million due to the impact of a $50 million insurance recovery.

The effective tax rate on third-quarter 2010 GAAP-basis earnings was 30.1%, compared to 32.8% in the third quarter of 2009. The effective tax rate on operating-basis earnings for the third quarter of 2010 was 28.1%, in line with our previously disclosed outlook. The effective tax rate on operating-basis earnings for the full year 2010 is expected to be between 28% and 29%.

THIRD-QUARTER 2010 RESULTS VS. SECOND QUARTER 2010

Servicing fees were $989 million, up 3% from $957 million in the second quarter due primarily to the impact of the Intesa acquisition and new business installed, offset partly by lower daily average equity valuations. Daily average values as measured by the S & P 500 declined 3% and were up about 1% as measured by the MSCI EAFE index^ES. Management fees were $213 million, down 2% from $217 million, due primarily to the mix of business reflected in the assets under management, offset partially by higher average month-end equity market valuations. Average month-end equity valuations were essentially flat as measured by the S & P 500 and increased 5% as measured by the MSCI EAFE index^ES. Trading services revenue was $228 million, down 30% compared to $326 million due to lower volatility and volumes in foreign exchange as well as lower fees from transition management and electronic trading in brokerage and other fees. Securities finance revenue was $68 million, down 38% from $109 million in the second quarter primarily due to lower spreads and slightly lower volumes associated with the traditional second-quarter seasonality. Processing fees and other revenue decreased from $87 million to $71 million due primarily to lower revenue from tax-advantaged investments. Fully taxable-equivalent net interest revenue in the third quarter of 2010 totaled $757 million, including discount accretion. On an operating basis, fully taxable-equivalent net interest revenue in the third quarter of 2010 was $568 million, up from $517 million in the second quarter of 2010 due to favorable yields in our investment portfolio, the full-quarter impact of the Intesa deposits, and a modest decline in funding costs.

Compared to the second quarter of 2010, salaries and benefits expense increased 5% to $871 million from $828 million primarily due to the impact of the acquisition of Intesa and the effect of the second-quarter reduction in incentive compensation associated with the charge recorded in the second quarter related to the securities finance lending programs. Information systems and communications expense was $181 million, up 4% due primarily to the impact of the Intesa acquisition. Other expenses were $189 million, up 2%, due to increased securities processing costs, offset partially by a higher level of recoveries.

ADDITIONAL INFORMATION

All per share amounts represent fully diluted earnings per common share. Return on common shareholders’ equity is determined by dividing annualized net income available to common equity by average common shareholders’ equity for the period. Operating-basis return on common equity utilizes annualized operating-basis net income in the calculation. Positive operating leverage is defined as the excess rate of growth of total revenue over the rate of growth of total expenses, each determined on an operating basis.

This news release includes financial information presented on a GAAP basis as well as on an operating basis. Management measures and compares certain financial information on an operating basis, as it believes that this presentation supports meaningful comparisons from period to period and the analysis of comparable financial trends with respect to State Street’s normal ongoing business operations. Management believes that operating-basis financial information, which reports revenue from non-taxable sources on a fully taxable-equivalent basis and excludes the impact of revenue and expenses outside of the normal course of business, facilitates an investor’s understanding and analysis of State Street’s underlying financial performance and trends in addition to financial information prepared in accordance with GAAP. Non-GAAP financial measures should be considered in addition to, not as a substitute for or superior to, financial measures determined in accordance with GAAP. A full reconciliation of operating-basis results to GAAP results is included in the addendum at the end of this news release.

Management believes that the use of non-GAAP financial measures in the calculation of capital ratios is useful to understanding State Street’s capital position and of interest to investors. Below is a description of, and other information with respect to, the capital ratios referenced in this news release.

The tier 1 capital and tier 1 leverage ratios are capital ratios used regularly by bank regulatory authorities to evaluate the Company’s capital adequacy. The tier 1 common ratio was used by the Federal Reserve in connection with its 2009 Supervisory Capital Assessment Program. The TCE and TCE/risk-weighted assets ratios are other capital ratios management believes provide additional context for understanding and assessing the Company’s capital adequacy.

• The tier 1 risk-based capital, or tier 1 capital, and tier 1 leverage ratios, as applicable, are each calculated in accordance with applicable bank regulatory requirements.
• The tier 1 risk-based common, or tier 1 common, ratio is calculated by dividing (a) tier 1 capital less non-common elements including qualifying perpetual preferred stock, qualifying minority interest in subsidiaries and qualifying trust preferred securities, by (b) total risk-weighted assets, which assets are calculated in accordance with applicable bank regulatory requirements. The tier 1 common ratio is not required by GAAP or on a recurring basis by bank regulations. Management is currently monitoring this ratio, along with the other capital ratios described in this news release, in evaluating State Street’s capital levels and believes that, at this time, the ratio may be of interest to investors. Reconciliations with respect to unaudited tier 1 common capital as of September 30, 2010, June 30, 2010, and September 30, 2009 are provided in the addendum at the end of this news release.
• The ratio of tangible common equity to adjusted tangible assets, or TCE ratio, is calculated by dividing consolidated total common shareholders’ equity by consolidated total assets, after reducing both amounts by goodwill and other intangible assets net of related deferred taxes. Total assets reflected in the TCE ratio also exclude cash balances on deposit at the Federal Reserve Bank and other central banks in excess of required reserves. The TCE ratio is not required by GAAP or by bank regulations, but is a metric used by management to evaluate the adequacy of State Street’s capital levels. Since there is no authoritative requirement to calculate the TCE ratio, our TCE ratio is not necessarily comparable to similar capital measures disclosed or used by other companies in the financial services industry. Tangible common equity and adjusted tangible assets are non-GAAP financial measures and should be considered in addition to, not as a substitute for or superior to, financial measures determined in accordance with GAAP. Reconciliations with respect to the calculation of the unaudited TCE ratio as of September 30, 2010, June 30, 2010, and September 30, 2009 are provided in the addendum at the end of this news release.
• The ratio of tangible common equity to risk-weighted assets, or TCE/RWA ratio, is calculated by dividing consolidated total common shareholders’ equity (reduced by goodwill and other intangible assets net of related deferred taxes) by total risk-weighted assets (determined in accordance with applicable bank regulatory requirements). The TCE/RWA ratio is not required by GAAP or by bank regulations, but is a metric used by management to evaluate the adequacy of State Street’s capital levels. Since there is no authoritative requirement to calculate the TCE/RWA ratio, our TCE/RWA ratio is not necessarily comparable to similar capital measures disclosed or used by other companies in the financial services industry. Tangible common equity is a non-GAAP financial measure and should be considered in addition to, not as a substitute for or superior to, financial measures determined in accordance with GAAP. Reconciliations with respect to the calculation of the unaudited TCE/RWA ratio as of September 30, 2010, June 30, 2010 and September 30, 2009, are included in the addendum at the end of this news release.
