State Street Expands Partnership with Korea's NPS, Lands Treasury Role, and Launches Stablecoin Fund

State Street (STT) landed one of its highest-profile mandates of the year when the U.S. Treasury Department selected the firm's SPDR Portfolio S&P 500 ETF (SPYM) as the exclusive default investment option for Trump Accounts, the new tax-advantaged children's savings program created under the Working Families Tax Cut Act and set to launch July 4, 2026 . SPYM, which tracks the S&P 500 at a 0.02% expense ratio, was chosen over rival options from BlackRock (IVV, ITOT) and Vanguard (VTI); State Street's own SPDR Portfolio S&P 1500 Composite Stock Market ETF (SPTM) was named as a secondary alternative .

Separately, State Street extended its long-running asset-servicing mandate with Korea's National Pension Service (NPS), one of the world's largest pension funds with roughly 1,670 trillion won ($1.1 trillion) in total assets. The renewed agreement, part of a relationship dating to 2014 with prior extensions in 2018 and 2021, keeps State Street as custodian and middle-office provider for NPS's global equities and alternatives portfolios, about 600 trillion won ($400 billion) of the fund's assets, covering custody, fund accounting, performance and analytics, mandate compliance, securities lending, and trade processing .

State Street Investment Management also launched the State Street Stablecoin Reserves Money Market Fund on June 16, 2026, a Rule 2a-7 government money market fund holding only GENIUS Act-eligible collateral: short-term U.S. Treasuries maturing in 93 days or less, overnight repurchase agreements collateralized by those Treasuries, and cash . The fund launched with about $121 million in assets and a 3.51% yield, with State Street Bank and Anchorage Digital as its first investors, positioning State Street alongside BlackRock and Goldman Sachs in the competition to custody stablecoin reserves ahead of projected industry issuance of $1.9 trillion to $4 trillion by 2030 .

Taken together, the three developments point to a State Street diversifying beyond legacy custody revenue on two fronts: deepening ties with Asia-Pacific's largest asset owners while building index-fund and digital-asset infrastructure tied to new regulatory frameworks. The Treasury-selected default ETF slot and the stablecoin reserves fund both give State Street recurring, policy-linked revenue streams, tied respectively to the Working Families Tax Cut Act and the GENIUS Act, rather than one-off wins, a pattern consistent with management's stated push to grow fee income beyond traditional asset servicing.
