Bitcoin’s Inflation-Hedge Case Has Costs Leverage Can Worsen

Bitcoin investors can lose returns through forgone interest income, borrowing costs and futures premiums even when the cryptocurrency’s price does not change. Higher interest rates can increase the cost of borrowing to buy Bitcoin and hold the position while waiting for a gain.

A $10,000 cash purchase has no interest bill, but the investor gives up income that could have been earned elsewhere. The three-month U.S. Treasury constant-maturity yield was 4.26% on Oct. 13. At that rate, $10,000 could have generated about $426 over one year before taxes.

An investor who contributes $10,000, borrows another $10,000 at a hypothetical 8% annual rate and buys $20,000 of Bitcoin would owe $800 in interest over one year. If Bitcoin finishes at the same price, the cash investor would still have $10,000 before fees. The leveraged investor would have $9,200 after repaying the loan and interest.

Bitcoin would need to rise 4% for the leveraged investor to cover the $800 interest charge. To match the hypothetical $426 Treasury return, Bitcoin would need to gain about 6.13%. A 10% increase would produce a higher return for the leveraged investor than for the cash buyer, while a 10% decline would result in a larger loss.

The calculation assumes the investor holds the position for the full year. A sharp interim decline can trigger a margin call, requiring more collateral, or lead a lender or exchange to liquidate the position. An investor can correctly predict Bitcoin’s eventual price and still lose the position before a recovery.

Dated futures contracts can include financing costs in their prices. If spot Bitcoin trades at $80,000 and a contract settling in 90 days trades at $81,200, the $1,200 premium equals 1.5% of the spot price, or about 6.08% on an annualized basis. If Bitcoin remains at $80,000 at settlement, the futures buyer loses $1,200 per Bitcoin of exposure as the contract price converges with the spot market.

Traders can buy spot Bitcoin and sell a more expensive futures contract as part of an arbitrage trade. Funding the spot purchase may require borrowing, linking futures premiums to interest rates and dollar financing costs. Futures prices also reflect demand for leveraged exposure, capital available for arbitrage and trading restrictions.

Perpetual futures have no scheduled settlement date. Exchanges use funding payments to keep their prices near a reference market. Those payments can rise, fall or reverse based on traders’ positions. Government borrowing costs can remain high while perpetual funding becomes negative during a sell-off.

The total cost of a derivatives position also depends on the holding period, collateral returns, margin requirements, trading fees and funding payments. Investors must avoid counting a dated futures premium and a separate borrowing cost as two full charges for the same financing.

Bitcoin’s supply is capped at 21 million coins, a feature often cited in arguments that the cryptocurrency can protect wealth from currency debasement. A higher consumer-price index does not automatically increase Bitcoin’s price. Inflation measures changes in the cost of goods and services, while Bitcoin’s return depends on the price future buyers are willing to pay.

Treasury Inflation-Protected Securities adjust their principal in line with the relevant inflation index. The 10-year inflation-indexed Treasury had a constant-maturity yield of 2.88% on Oct. 13. Investors who sell before maturity can still face losses if market yields rise.

The September U.S. inflation report showed consumer prices rising 3.7% from a year earlier. Higher inflation can contribute to elevated interest rates, increasing costs for borrowers. Cash buyers can hold Bitcoin through a weak period while giving up income available elsewhere. Borrowers must pay interest and maintain collateral, while futures traders must account for premiums, funding payments, margin requirements and trading fees.
