Federal Reserve Policy: The Fed's interest rate decisions directly impact DWGXX's yield. Lower rates mean lower yields and vice versa.

Market Interest Rates: Changes in overall money market rates influence DWGXX's competitiveness. Rising rates elsewhere can make DWGXX less attractive.

Credit Risk: While DWGXX primarily invests in high-quality securities, perceived or actual credit risk in its holdings can affect its net asset value.

Supply and Demand: High demand for safe-haven assets, especially during economic uncertainty, can increase DWGXX's price and conversely.

Fund Expenses: The fund's management fees and operating expenses are deducted from its returns, impacting the overall yield and effective price.

Economic Conditions: Economic growth, inflation, and unemployment rates all indirectly affect interest rates and investor sentiment towards risk, influencing DWGXX.

Regulatory Changes: New regulations impacting money market funds can alter their investment strategies and risk profiles, potentially affecting prices.
