The $7.9 Trillion Question: Is Too Much Cash Becoming a Risk?

Cash is paying again. But when does short-term comfort start competing with long-term goals?

For years, holding cash came with an obvious drawback: it earned very little.

That changed as interest rates moved higher. Short-term investments became more attractive, and investors responded.

As of August 12, 2026, assets in U.S. money-market funds reached approximately $7.93 trillion, according to the Investment Company Institute.

So, if cash is finally paying investors to wait, why not keep waiting?

Because cash can be an excellent short-term tool without necessarily being the right long-term strategy.

Why cash looks attractive

The appeal is understandable.

The Federal Reserve's current target range for the federal funds rate is 3.50%–3.75%, supporting relatively attractive yields on many short-term instruments.

Cash and cash-like investments also offer something equities cannot: significantly less day-to-day price volatility.

But there is an important trade-off.

Today's rate is not tomorrow's rate

Money-market fund yields generally move with short-term interest rates. If rates decline, the income investors receive from these funds will typically decline as well.

Consider a simple hypothetical:

$100,000 earning 4% = $4,000/year

If the available rate falls to 3%, that becomes $3,000. At 2%, it becomes $2,000.

Your principal does not need to fall for your income to change.

Hypothetical example for illustrative purposes only.

“Low risk” does not mean “no risk”

Investment risk is about more than market volatility.

Holding too much in cash can expose investors to other considerations:

• Inflation risk: returns may not keep pace with rising prices.

• Reinvestment risk: future rates may be lower.

• Opportunity cost: capital held in cash is unavailable for other investments.

• Long-term growth: a portfolio may not compound enough to meet future objectives.

The better question isn't simply, “Is cash safe?”

It's “What does this money need to accomplish?”

Give every dollar a job

Money needed for an emergency reserve, upcoming tax payment, home purchase or another near-term expense has a reason to remain liquid.

Capital intended for retirement or another goal decades away has a different job.

It may need to grow.

That's why holding cash for a defined purpose is very different from holding long-term capital in cash indefinitely while waiting for the “perfect” time to invest.

Markets rarely provide that perfect moment.

Quick read

Cash can make sense when:

• You need near-term liquidity.

• You're maintaining an emergency reserve.

• You have an upcoming financial obligation.

• The allocation is intentional within your broader strategy.

It may be time to reassess when:

• Long-term capital remains uninvested without a defined reason.

• Today's yield is driving your entire decision.

• Fear of volatility has replaced a long-term investment plan.

• Your cash allocation has grown beyond your actual liquidity needs.

With approximately $7.93 trillion in U.S. money-market funds, investors clearly continue to value liquidity and short-term income.

The question isn't whether cash is good or bad.

It's whether the amount you hold matches your time horizon and financial objectives.

Seaview's Approach: Liquidity With Purpose

At Seaview Investment Managers, we view cash as one component of a broader portfolio—not a strategy in isolation.

The appropriate allocation depends on liquidity needs, investment horizon, risk tolerance, tax considerations and long-term objectives.

Our approach focuses on maintaining appropriate liquidity while balancing income, risk management and long-term capital appreciation.

Cash can provide flexibility and peace of mind. But capital intended to compound over decades may require something different.

The question isn't whether you should hold cash. It's whether your cash is doing the job you need it to do.
