Bitcoin's derivatives market went quiet before CPI — but the leverage didn't go anywhere

Bitcoin perpetual futures activity on the two largest venues has fallen to its lowest level in about three years, according to research and brokerage firm K33, whose Head of Research Vetle Lunde described the market as being in a state of "hibernation." The 30-day average combined trading volume for BTC/USDT perpetuals on Binance and Bybit stood at $10.8 billion as of Aug. 10, K33 said in a report covered by The Block on Wednesday. Lunde put that in historical terms: only 5% of days since January 2021 have recorded lower 30-day average volumes across those two products, and those days cluster in late 2022 and 2023.

Spot has thinned out alongside it. K33 measured average daily bitcoin spot volume down 18% over the past week to $1.8 billion — the lowest one-week average since February 2024. Realized volatility has followed: bitcoin's seven-day volatility printed 0.6% on Sunday, which K33 called the lowest reading since Christmas 2025.

The price backdrop explains most of it. Bitcoin has traded roughly between $60,000 and $80,000 for six consecutive months, per K33, and sits close to a 50% drawdown from its October 2025 all-time high. On Wednesday morning it was going nowhere in particular: CoinDesk had it up 0.23% since midnight UTC at around $63,979, with total crypto market capitalization at $2.19 trillion and the Fear and Greed index at 38.

The part that isn't quiet

The interesting wrinkle in K33's data is that traders have stopped trading without unwinding their positions. Open interest in bitcoin perpetuals averaged around 300,000 BTC between June 1 and Aug. 11, above what the firm reports as a 2026 average of 288,000 BTC. "This suggests that relative leverage in the market remains elevated, creating modestly heightened risks of amplified volatility and trading activity stemming from liquidations," Lunde said. "The prolonged combination of elevated open interest and volatile, yet relatively moderate, funding rates leaves the market exposed to liquidation-driven moves in either direction."

Falling volume against flat-to-higher open interest is the specific combination that produces gap moves: fewer resting orders to absorb a liquidation cascade, but the same amount of leverage waiting to be liquidated.

CoinDesk's derivatives readout describes the same structure from a different angle and reaches a compatible conclusion. Bitcoin's 30-day implied volatility index (BVIV) receded to 37.5% from Monday's high of 38.66%, and short-dated one-week implied vols remain low — which CoinDesk read as options traders not pricing much of a move around CPI. On Deribit, the $70,000 call was the most actively traded contract for a second consecutive day, while CoinDesk noted growing demand for strangles, the simultaneous purchase of puts and calls that pays off on a sharp move in either direction rather than a directional one.

The macro trigger

The July U.S. Consumer Price Index report is due Wednesday at 8:30 a.m. ET / 12:30 UTC. Economists polled by Reuters expect headline CPI to rise 0.1% month over month and 3.4% year over year, with core CPI up 0.2% month over month and 2.5% year over year, per The Block. The gap between a 3.4% headline and a 2.5% core points at energy, and energy is doing something: CoinDesk put Brent crude near $90 a barrel after fresh Houthi attacks on shipping in the Bab el-Mandeb Strait and a U.S. strike on a vessel in the Gulf of Oman overnight.

The line most worth reading twice is the rates one. Per the CME FedWatch tool as cited by The Block, markets were pricing roughly a 50% chance of a 25-basis-point hike at the September meeting going into the print — not a cut.

Harmony

The day's one large move was a failure, not a rally. Harmony, a layer-1 network, confirmed an exploit early in the Asian session in which an attacker minted roughly 4 billion ONE tokens through empty blocks. CoinDesk described that as about 26% of supply — its summary says total supply, its body says circulating supply, and the two are not the same thing. Around 2.8 billion of the minted tokens were moved to exchanges quickly, per CoinDesk, and ONE fell as much as 40% to a record low. The Block's news file carries a matching headline confirming the unauthorized mint of 4 billion ONE.

Elsewhere in positioning, CoinDesk reported the taker long-short ratio has flipped bearish with shorts at 51.36% of activity, a reversal from earlier in the week; AVAX open interest up 6% into falling prices with the most negative cumulative volume delta among majors; and DOGE futures open interest above 17.2 billion tokens — the most since October, up from a June low of 12 billion — while the price stayed pinned near 7 cents. CRV was the week's standout, up roughly 35% over seven days to around 28 cents, which CoinDesk said coincides with a 15% annual emissions reduction due to trigger imminently. UNI fell more than 10% in 24 hours with no catalyst CoinDesk could identify.

The real-world read

The open interest figures do not reconcile, and neither outlet says so. K33 puts bitcoin perp open interest around 300,000 BTC; CoinDesk, on the same morning, says bitcoin open interest is "hovering below 750,000 BTC." These are almost certainly different scopes — K33 is explicitly measuring Binance and Bybit perpetuals, CoinDesk appears to mean aggregate futures across venues — but neither states its universe precisely enough for a reader to check. Treat any "open interest is X" headline as meaningless without the venue list.

One of K33's comparison figures, as rendered, is self-contradictory. The Block reports open interest averaging 300,000 BTC "compared with a 2026 average of 288,000 BTC and 282,000 BTC across 2025 and 2026." The same year cannot have two averages; one of those labels is wrong. The directional claim — leverage is elevated relative to trend — survives, but the specific numbers should not be quoted with confidence until K33's report is read directly.

K33 is a brokerage. It sells execution. A research note arguing that a quiet market is coiled for a liquidation-driven move in either direction is honest analysis and also a description of conditions under which trading is worth doing. That is not a reason to dismiss the data, which is checkable; it is a reason to notice who benefits from the framing.

"The market may be underpricing the actual event risk" is an opinion, and CoinDesk doesn't say whose. Much of CoinDesk's derivatives section — the DOGE market being "coiled for a significant volatility event," the underpricing of CPI risk — is unattributed analytical voice presented in the same register as the OI and CVD numbers. The numbers may well come from a data vendor; no vendor is named for the CVD or long-short figures either.

The 26% is doing a lot of work in the Harmony story, and it's inconsistent. Total supply and circulating supply produce materially different pictures of dilution, and CoinDesk uses both within one piece. Separately, what has not been explained publicly is how the attacker obtained the ability to mint through empty blocks — a validator- or consensus-level failure, not an ordinary contract bug — nor whether any exchange froze the roughly 2.8 billion tokens that arrived on their books, nor whether any recovery is contemplated. Those are the questions that determine whether ONE holders get anything back.

A hike is the underplayed fact of the day. Roughly even odds on a September increase is a materially different world from the rate-cut expectations that have underpinned most crypto commentary this cycle, and both pieces mention it in passing at most.

K33's on-chain consolation carries no methodology. The claim that this consolidation differs from 2014, 2018 and 2022 — no lower lows, coins "moving back into the hands of long-term holders" — is the standard reassurance offered during drawdowns, and it arrives without a stated entity-clustering method or holding-period threshold. Note that CoinDesk's own news file the same morning carries a headline about "one overlooked group" adding $1.78 billion of selling pressure to bitcoin; the details aren't visible from the file, but the two narratives are not obviously compatible.

The pages carry advertising, and it should not be mistaken for reporting. The Block's page includes a promotional unit for LMAX Digital and a Polymarket-branded explainer; CoinDesk's carries a promotional item on Zcash's Tachyon upgrade. None of that is journalism and none of it informed this account. The Block also discloses that Foresight Ventures is its majority investor and that Bitget is an anchor LP for Foresight — worth holding in mind in a story whose central data point is exchange volume rankings, even though the venues measured here are Binance and Bybit.

The quiet has a payroll cost. Sitting in The Block's news file alongside the hibernation story: Bitwise cutting 14% of staff "as crypto layoffs mount during market downturn." Six months of $10.8 billion perp volume is not a neutral state for firms that earn on flow.

Finally, the price itself moves around within a single page. CoinDesk's article variously shows ~$63,979, ~$63,900 and a $64,104.06 ticker, with adjacent headlines citing $63,600 and $63,700. These are snapshots at different minutes, not contradictions — but it's a useful reminder of how much precision to grant a quoted spot price.

Opinion, and whose

• Vetle Lunde, K33 — the market is in a self-reinforcing "hibernation," and elevated open interest against low volume creates "modestly heightened risks of amplified volatility" from liquidations in either direction. Analysis, not fact; K33 is a brokerage.
• K33 (firm) — this consolidation is structurally unlike 2014, 2018 and 2022 because bitcoin has stopped making lower lows and coins are returning to long-term holders. Interpretation of on-chain data, method unstated.
• CoinDesk (unattributed desk commentary) — options traders are not pricing a big CPI move, so the market "may be underpricing the actual event risk"; DOGE's leverage buildup suggests it is "coiled" for a volatility event. Opinion presented without a named analyst.
• Economists polled by Reuters — headline CPI +0.1% m/m and 3.4% y/y, core +0.2% m/m and 2.5% y/y. A forecast.
• Futures markets, via CME FedWatch — roughly 50/50 on a 25bp September hike. A market-implied probability, which is a price, not a prediction of record.

None of the above is a statement about where anything will trade.
