Present Value

Present value is the current worth of a future sum of money, calculated by discounting it at an interest rate that reflects time and risk. The standard formula divides the future amount by one plus the rate, raised to the number of periods. At a 5 percent discount rate, 1,000 dollars arriving ten years from now has a present value of about 614 dollars.

Why it matters

Present value is the foundation of asset pricing. Bond prices, stock valuations, pension liabilities, and real estate appraisals all rest on discounting expected future cash flows back to today. Small changes in the discount rate produce large changes in value for long-dated assets, which is why interest rate cycles move markets so forcefully. When rates fell toward zero in 2020, the present value of distant cash flows rose sharply, and when rates climbed in 2022 that effect reversed.

In the gold vs bitcoin debate

Neither gold nor bitcoin produces cash flows, so neither can be valued by discounting. Their prices instead reflect monetary demand and the opportunity cost of holding them. That opportunity cost is itself a present value concept: when real yields on bonds are high, holding a non-yielding asset forgoes more, and when real yields are low or negative the forgone income shrinks. Both assets have historically been sensitive to that calculus.
