Washington State Investment Board (WSIB)

The Washington State Investment Board (WSIB), established in 1981, is an independent fiduciary responsible for managing investments for public retirement and trust funds in Washington State. Operating from Olympia, WSIB oversees assets for 17 retirement plans, including those for public employees, teachers, law enforcement officers, firefighters, and judges. Additionally, it manages funds supporting the state's industrial insurance programs, educational institutions, and developmental disability services.

With assets under management totaling approximately $211.5 billion as of April 2025, WSIB employs a diversified investment strategy across various asset classes, including public equity, fixed income, real estate, private equity, and tangible assets. The board emphasizes prudent risk management and seeks to maximize returns to fulfill its fiduciary duties to beneficiaries. WSIB's investment activities span globally, reflecting its commitment to diversification and long-term growth.

WSIB also implements an Economically Targeted Investments (ETI) policy, aiming to invest in opportunities that, while meeting fiduciary standards, also benefit Washington's economy. As of June 2024, the board had allocated $5.8 billion to Washington-based investments across sectors such as communications services, healthcare, and information technology. This approach underscores WSIB's dedication to supporting local economic development alongside achieving strong investment performance.
