Interest Rates: Changes in benchmark interest rates set by the Federal Reserve directly impact the yields and therefore the price of money market funds like WGSXX. Higher rates lead to higher yields, increasing attractiveness.

Credit Quality: The creditworthiness of the securities held in WGSXX's portfolio, such as government bonds and commercial paper, affects its price. Downgrades can decrease the fund's net asset value.

Maturity of Holdings: The average maturity of the fund's holdings influences price sensitivity to rate changes. Longer maturities typically lead to greater price volatility when rates shift.

Supply and Demand: Investor demand for WGSXX shares influences its market price. Increased demand can drive the price slightly above its net asset value (NAV).

Economic Conditions: Overall economic health impacts interest rates and creditworthiness, indirectly affecting the fund's value. Strong economies can lead to higher rates.

Regulatory Changes: New regulations regarding money market funds can alter their operational constraints and investment strategies, potentially impacting their price.
