Bitcoin traders buy $70K calls, strangles as CPI looms

Bitcoin and ether traders are positioning for Wednesday's U.S. CPI print, buying $70,000 calls and strangles to profit from a breakout of the $62,000–$66,000 range.

"Dominant flow on Deribit BTC options since yesterday has been concentrated in the 25SEP26 70k call," data tracking platform Laevitas said. Traders who bought that September expiry call paid roughly $2.5 million in total premium — their maximum loss if bitcoin stays below $70,000 through month-end.

Economists expect the July report to show headline CPI rising 0.1 percent month-over-month and 3.4 percent year-over-year, with core CPI forecast at 0.2 percent month-over-month and 2.5 percent year-over-year, per consensus estimates from Reuters, Dow Jones, and Bloomberg surveys. A hotter print would strengthen the case for a Federal Reserve rate hike in September, push Treasury yields higher, and keep pressure on risk assets. A softer number would do the opposite.

The result could push bitcoin, trading near $63,700, out of the range it has occupied for weeks, with ether near $1,888. Either scenario carries implications for the broader crypto market as the Fed's next move shapes risk appetite.

Volatility plays dominate as implied volatility sits depressed

Other traders are less focused on direction and more interested in a jump in volatility. "We reiterate our recommendation to accumulate December optionality, leveraging depressed implied volatility across the curve ahead of several key catalysts, notably updates on bipartisan Clarity Act negotiations, shifts in Middle East geopolitical risks, and potential monetary policy pivots," TDX Strategies said, adding that it structurally favors December strangles on BTC and SOL.

A strangle involves buying both a call and a put with the same expiration. The position profits if the price makes a large move in either direction, with maximum loss limited to the combined premium paid.

Volatility could expand quickly once bitcoin breaks out of its recent range, according to Jeff Anderson, managing partner at market-making firm STS Digital. "A decisive break of either level in spot should see volatility expand quickly, and the closely watched CPI this Wednesday will be our first indicator following Warsh's inflation focused press conference," Anderson told CoinDesk. "It is also worth noting the looming seasonal backdrop: September has historically been Bitcoin's weakest month, down roughly 4 percent on average since 2013."

On-chain accumulation meets guarded derivatives positioning

On the blockchain, the picture looks more constructive for the bulls. Major coins are leaving exchanges, a sign of accumulation, even as some sophisticated traders remain cautious in the derivatives market, according to analytics firm Nansen. "On spot, the majors are being accumulated, not distributed: ETH saw exchange net outflows of $49.7M over the past day and $164.6M over the past week, meaning coins are leaving exchanges rather," Jake Kennis, senior research analyst at Nansen, said in an email.

Kennis added that the "derivatives picture is more guarded," with smart traders on the decentralized exchange Hyperliquid holding a net short exposure of $46.8 million in bitcoin and $20.9 million in ether.

Taken together, the positioning points to a market that is cautiously optimistic on both price and volatility as the key inflation data approaches. A softer-than-expected CPI could trigger a decisive move toward $70,000, while a hot print risks a breakdown below $62,000 — either scenario rewarding traders who positioned for volatility.
