These dated entries organise news across the calendar week. Related daily report links do not identify the stored reports reused in the weekly analysis; those inputs are listed separately.
Bitcoin’s week was shaped by a renewed institutional bid, an abrupt change in the US rates narrative and a large derivatives expiry. Treasury plans for bigger bond buybacks helped weaken the dollar and revive the debasement trade, while strong ETF inflows carried Bitcoin through $80,000. Inflation data and Kevin Warsh’s Jackson Hole debut later restored some policy caution. The options market traced the same unsettled path: front-end volatility rose sharply, reversed just as quickly and ended the week 8.75 points lower at the one-week tenor.
Bitcoin’s rebound returns corporate treasuries to firmer ground
A quiet macro session left crypto-specific positioning in charge. Bitcoin’s recovery improved the mark-to-market position of large corporate holders, while increasingly bullish year-end forecasts underlined how quickly sentiment had turned after the earlier drawdown.
Macro
No material scheduled macro release in the source set displaced the crypto rebound as the principal market story for the session.
Crypto
Strategy’s Bitcoin treasury moved back towards break-even as the market rallied, while Standard Chartered argued that its $100,000 year-end target might prove conservative.
ETF demand supplies the weekend’s clearest signal
With conventional markets largely absent, fund flows provided the cleanest account of demand. US spot Bitcoin ETFs had taken in $1.92bn over the week, their strongest showing since October 2025, even as the options surface softened modestly into Sunday.
Macro
The weekend produced no sufficiently material macro event in the source set, leaving the coming Jackson Hole programme as the next policy focus.
Crypto
US spot Bitcoin ETFs recorded their strongest weekly inflow in ten months, reinforcing the institutional bid after Bitcoin briefly moved above $78,000.
Jackson Hole moves into view as Strategy builds a cash buffer
Markets began the working week looking towards Kevin Warsh’s first Jackson Hole address, with bond-market unease setting the tone. In crypto, Strategy raised $2bn through share sales and created a dollar reserve rather than immediately adding to its Bitcoin holdings.
Macro
The new Fed chair faced an early communications test as investors looked for clarity on inflation, productivity and the pressure building in longer-dated government bonds.
Crypto
Strategy raised $2bn from equity sales and established a dollar liquidity reserve, extending its pause in Bitcoin purchases while preserving capacity for future buying.
Treasury buybacks weaken the dollar and carry Bitcoin towards $80,000
Plans to expand purchases of older long-dated Treasuries flattened the yield curve and pushed investors back towards the debasement trade. Bitcoin approached $80,000 after the strongest week of ETF demand in ten months, while short-dated implied volatility and call skew rose with it.
Macro
The US Treasury’s proposed expansion of bond buybacks drove the day’s cross-asset move, supporting gold, flattening the curve and weighing on the dollar.
Crypto
Bitcoin’s rally accelerated towards $80,000 after a strong run of US ETF subscriptions, pushing the asset back to the centre of the broader liquidity trade.
Inflation edges higher as the market turns towards Friday’s expiry
July’s US personal income and spending report kept inflation risk alive without producing a decisive macro shock. Crypto attention shifted from the rally to market structure: ETF inflows remained firm, but a $6.4bn Bitcoin options expiry now loomed over the end of the week.
Macro
US personal income rose 0.4 per cent in July and the Fed’s preferred inflation measure ticked higher, leaving policy expectations sensitive ahead of Jackson Hole.
Crypto
The market began to position around Friday’s $6.4bn Bitcoin options expiry, even as another burst of subscriptions extended the run of strong US spot ETF demand.
Nvidia lifts risk appetite while Europe keeps its policy options open
A strong Nvidia result supported technology shares and Bitcoin, but central-bank caution did not disappear. The ECB’s July account showed a market still shaped by trade, energy and geopolitical risks, while Bitcoin ETF inflows slowed and derivatives traders prepared for settlement.
Macro
The ECB’s July meeting account described a still-uncertain inflation and growth outlook, with financial conditions exposed to trade policy, energy prices and geopolitics.
Crypto
Deribit’s weekly review linked the break in August’s volatility lull to the Treasury buyback story. Spot ETF inflows slowed to $232m, though their eight-day total reached $2.8bn.
Warsh’s inflation warning lands as $6.4bn of Bitcoin options expire
The week ended with monetary policy and derivatives positioning colliding in the same session. Kevin Warsh resisted giving markets an easing signal at Jackson Hole, Bitcoin struggled to sustain $80,000 and the expiry was followed by a sharp fall in one-week implied volatility.
Macro
At Jackson Hole, Kevin Warsh said the Fed still had work to do on inflation and gave no steer towards near-term rate cuts, keeping the policy backdrop restrictive for risk assets.
Crypto
The $6.4bn Deribit expiry covered almost one-fifth of the exchange’s Bitcoin open interest. Bitcoin had earlier joined a broader risk rally after Nvidia’s earnings but failed to hold a clean break above $80,000.
