Money Market Funds (MMFs): A Low-Risk Investment Vehicle

Money Market Funds (MMFs) are mutual funds that invest in short-term, high-quality debt securities and aim to provide high liquidity and low risk.

Historical Context

Money Market Funds (MMFs) originated in the 1970s as a response to interest rate ceilings imposed on bank savings accounts. They allowed investors to earn market rates on short-term investments, presenting an attractive alternative to traditional savings accounts. The first MMF was introduced in 1971 by the Reserve Fund.

Types/Categories

• Prime MMFs: Invest in a variety of short-term corporate and bank debt securities.
• Government MMFs: Primarily invest in U.S. government securities.
• Treasury MMFs: Exclusively invest in U.S. Treasury securities.
• Municipal MMFs: Invest in short-term municipal securities.

Key Events

• 1971: The establishment of the first Money Market Fund by the Reserve Fund.
• 2008 Financial Crisis: Highlighted the systemic risk associated with MMFs, leading to reforms.
• 2016 SEC Reforms: New regulations introduced to improve the resilience and transparency of MMFs.

Detailed Explanations

Characteristics

• Liquidity: MMFs offer high liquidity, making it easy to access funds when needed.
• Low Risk: They invest in high-quality, short-term debt instruments, minimizing risk.
• Stable NAV: Many MMFs aim to maintain a stable Net Asset Value (NAV), usually $1 per share.
• Income Generation: MMFs generate income primarily through interest payments from underlying securities.

Mathematical Formulas/Models

MMFs often rely on amortized cost accounting to maintain their stable NAV. They may also use the Weighted Average Maturity (WAM) and Weighted Average Life (WAL) to measure portfolio risk.

Weighted Average Maturity (WAM) is calculated as follows:

$$ WAM = \frac{\sum_{i=1}^{n} (Days\ to\ Maturity_i \times Market\ Value_i)}{\sum_{i=1}^{n} Market\ Value_i} $$
