ETHA Options Flow Turns Defensive as Bitcoin Slips Below $78K; Stablecoin Supply Diverges

BlackRock's ETHA registered a put/call volume ratio of 1.63 at Friday's close, the most defensive single-day options tilt across major spot crypto ETFs, as bitcoin traded 1.1% lower at $77,502 through Monday's New York morning session. The hedging bid in ether products comes against a backdrop of flat ETH spot pricing and a $1.6 billion USDT supply expansion over the prior 24 hours.

Market Pulse

Bitcoin changed hands at $77,502 midday, down 1.05% on the session with a 1.5% intraday range. Ether held firmer at $2,271, off 0.2%, while SOL tracked BTC lower to $93.54 (-1.05%) and XRP ground out a 0.06% gain at $1.2514. Perpetual funding stayed modestly positive across venues — BTC, SOL and XRP each printed +0.0100% per 8h on Binance perpetual funding (annualized ~+10.9%), with ETH softer at +0.0024% (~+2.6% annualized). The funding mix points to light long positioning rather than directional conviction; nothing in the rate structure flags forced unwinds.

Options Positioning

ETHA's P/C volume ratio of 1.63 at the Friday close stands out against a call-skewed open-interest book (P/C OI 0.623), consistent with fresh downside hedging layered over existing long exposure. 30-day implied vol sits at 55.0%. Top put open interest clusters at the $10 and $5 strikes — 80%+ below the live ETF price of $51.26 — suggesting tail hedges rather than directional bearish bets.

IBIT, by contrast, carried a more balanced P/C volume of 0.904 at Friday's close, with IV30d at 40.3% and the heaviest call OI parked at the $50 strike (+14.2% vs the $43.78 live price). FBTC skewed outright bullish at P/C volume 0.472. The divergence between ETHA's defensive volume print and the BTC complex's steadier posture is the cleanest cross-asset signal on the tape. BSOL's P/C volume of 0.165 (as of Friday's close) marks the most call-heavy positioning in the ETF set, though open interest remains thin at 188 active contracts.

Narrative

Headline flow is dominated by security incidents. Brazil's Mercado Bitcoin halted withdrawals after an estimated $46 million theft, with loss estimates still climbing per multiple outlets. Separately, Binance completed a fresh proof-of-reserves attestation as it restores assets and withdrawals following its own record hack — a sequencing that appears to be absorbing attention without triggering visible contagion in spot or funding. The macro overlay is quiet; one commentator flagged U.S. midterm implications as more relevant for XRP than BTC, but there is no scheduled catalyst driving the morning tape.

Afternoon Watch

Mercado Bitcoin withdrawal status and any updated loss figure — a widening number has historically been associated with regional stablecoin outflows.
Stablecoin supply divergence: USDT +$1.62B / USDC -$556M over 24h, per InflowScan data. A continuation would be consistent with offshore capital staging while US-domiciled dollars drain.
16:00 UTC funding refresh — the next print will show whether ETH's lagging funding (+2.6% annualized vs BTC's +10.9%) persists.
