Buying Bitcoin without betting on a rally may not pay

Buying Bitcoin while hedging against a price drop can earn a return without a rally. But November 10 pricing offered about $119 per BTC before costs, less than the roughly $135 needed to finance the purchase for 17 days in an illustrative borrowing calculation.

The strategy, known as cash-and-carry, pairs a Bitcoin purchase with a futures sale. It seeks to earn the premium between the two markets as their prices converge. Its attraction depends on the cost of funding and maintaining both positions.

The comparison uses CME's November futures settlement and Coinbase's price during the settlement window. It implies about 3.48% gross annualized carry, against a 3.88% overnight financing benchmark.

A small Bitcoin premium

CME's preliminary bulletin No. 217, dated November 10, lists the November Bitcoin futures settlement at $73,805 per BTC.

Coinbase's BTC-USD candle beginning at 20:59 UTC closed at $73,685.73. That minute corresponds to 2:59--3:00 p.m. Central Standard Time, aligning with CME's stated daily settlement window.

Subtracting the Coinbase close from the futures settlement gives a $119.27 premium, or about 0.16% of the spot price. Using the 17-day calendar-date difference to November 27 expiry and a simple 365-day annualization produces the following sensitivity:

The range shows how much a short-dated annualized figure can move with a relatively small change in spot price.

These remain pricing proxies. Coinbase's candle close is a single venue's last trade within the minute, while CME's daily settlement methodology uses a volume-weighted futures price. A trader would need executable prices for both legs, at sufficient size, to establish an actual opportunity. Pairing the minute's lowest spot trade with the futures settlement does not demonstrate that both prices were simultaneously available.

CME's own BasisWatch methodology uses a separate 60-second spot marker.

Borrowing can swallow the reward

The New York Fed's dated SOFR observations show 3.88% effective November 9. SOFR measures overnight borrowing secured by Treasury securities. A Bitcoin trading desk's funding rate, collateral requirements and access to credit can differ materially.

There is also a convention difference. The carry calculation above uses a 365-day year. The New York Fed's money-market methodology uses actual calendar days divided by 360.

For illustration, financing the entire $73,685.73 spot purchase for 17 days at a constant 3.88%, using that 360-day convention, would cost approximately $135.01. Against the $119.27 gross premium, that leaves a $15.74 shortfall before trading and other costs.

Using the minute's low instead would leave roughly $21 per BTC after the same financing assumption, before other costs. That is a small remaining allowance, and it depends on a more favorable spot input than the closing-price proxy.

Future overnight rates, borrowing spreads, execution costs and collateral income remain unknown. An investor using its own cash would face an opportunity-cost decision rather than this hypothetical loan bill.

Margin adds another demand on capital. CME futures are marked to market daily. If Bitcoin rises, the short futures position can require cash payments even while the spot holding gains value elsewhere. The investor needs sufficient liquidity to maintain the hedge.

The 3.48% figure measures gross carry against the spot purchase price. Return on margin uses a different denominator again, and looking only at the futures deposit would omit the capital supporting the long position.

An ETF version also requires its own calculation using share prices and hedge ratios. Fund fees and premiums or discounts to net asset value affect the economics. For example, IBIT lists a 0.25% annual sponsor fee; buying its shares would not reproduce the Coinbase spot leg exactly.

December policy risk

The macro backdrop gives financing costs particular relevance. The October CPI release, published November 10, showed consumer prices rising 0.4% month over month, with core prices up 0.3%, both seasonally adjusted.

Before the release, Governor Christopher Waller said a core reading around 0.3% or higher would warrant considering a 50-basis-point December rate increase. Those were his conditional views, rather than a committee decision.

The November futures contract expires before the Fed's December 8--9 meeting. A December increase therefore would not become an already-incurred financing cost on a position completed at November expiry. Policy expectations can still affect present funding conditions and the economics of rolling into later contracts.

What would bring buyers in

US spot Bitcoin ETFs recorded $95 million in net outflows on November 10, following $201 million on November 9, according to Farside's completed daily rows.

Those totals establish continued aggregate redemptions. They do not identify investors' strategies or connect a particular ETF holding to a futures hedge.

The available CFTC financial futures report covers positions as of November 3, a week before the CPI session. It cannot establish how traders responded to November 10 prices. Its trader categories also lack a complete account-level view of corresponding spot and ETF holdings.

Evidence consistent with new carry demand would combine executable futures premiums that leave room after actual funding costs, additional spot or ETF exposure, and corresponding futures hedges. Comparable pricing across subsequent sessions would help distinguish a persistent incentive from a fleeting observation.

Bitcoin can also recover through stronger directional spot demand from buyers willing to take outright price risk. Cash-and-carry is one possible source of support, with its own financial hurdle.

For this hedged Bitcoin trade, the buying decision turns on the premium left after funding, execution and the cash needed to keep both positions open.
