Question 10
As budgets become more conservative and protective, a common trade-off emerges between liquidity (having cash readily available for short-term needs) and opportunity (putting money to work for higher returns). An emergency fund provides crucial protection but holding an excessively large emergency fund in low-yield savings can carry a meaningful opportunity cost: funds that could have compounded in retirement accounts or diversified investments are sitting idle, earning little more than inflation-adjusted zero. That said, the optimal size balances the household’s income stability, access to credit, near-term planned expenditures, and risk tolerance. For a dual-income household with stable employment, a smaller liquid cushion plus allocated sinking funds might make sense. For someone with higher income volatility, a larger cushion is often prudent. Financial advisors often discuss this as part of an overall plan: maintain adequate liquidity for short-term needs while diagnosing which dollars can be shifted to tax-advantaged or higher-return investments. The question asks you to identify the primary opportunity cost when someone holds too-big an emergency fund.
What is the primary opportunity cost of keeping an overly large emergency fund in very low-yield accounts?
