Positioning carries the tape

Macro

While there was some initial chatter around the Friday (28/08) option expiry potentially driving prices, it was Warsh's Jackson Hole keynote which was the catalyst for the market to start moving. He reconfirmed his commitment to the 2% inflation target, which was slightly more hawkish than anticipated, driving the odds of a September rate hike to 61.9% today.

He specified short rates as the Fed's predominant tool and dismissed the idea that summer's better prints reflect improved underlying trends, which leaves the September 15-16 meeting as a key catalyst for risky assets, including crypto, which investors should pen down in their diaries.

Looking at cross asset performance, 20Y+ Treasuries led our board at +1.01%, with altcoins up 0.61%, the S&P500 0.47%, the Nasdaq 0.42% and BTC 0.10%, while ETH fell 0.86%, the Russell 2k 1.40%, gold 3.42% and Brent 4.31%.

Duration leading the board while gold and oil took the bottom two lines is the market telling you it believes Warsh. All three assets price inflation credibility, and all three repriced in the Fed's favour. The same logic explains the Russell at the bottom of equities, because small caps price the short end that Warsh just threatened to raise.

The final catalyst of the week were the NVIDIA earnings, which have, since the start of the AI rally, been the "go-to" temperature check for that entire trade which has ramifications for the entire U.S. equity market and by now the economy. In short, NVIDIA beat its expectations and 3Q guidance was strong, however the stock still faded into Friday alongside the broader chip complex on the back of gross margins being guided down on rising memory cost, which some saw as the first crack in the AI infra trade, however jumping to that conclusion feels premature.

Digital Assets

BTC spent the week digesting its 23% move. It tested above $81k midweek, faded below $78k after the Warsh speech, and finished the week flat at +0.10%. That is a constructive print, since the tape absorbed a hawkish Fed chair, a chip selloff and month-end without giving back the breakout, and it confirms $82k as the resistance zone that has now rejected several attempts.

The ETF bid we flagged as the recovery signal kept paying. BTC ETFs took $924M on the week per Farside, running nine consecutive positive sessions before Friday snapped the streak with a $202M outflow, while ETH ETFs added $816M without a single negative day. Two straight weeks of institutional inflows is the difference between a short squeeze and a durable bid, and Friday's outflow is the first data point against it, worth watching rather than worrying about.

Under the surface, breadth held up better than ETH's -0.86% suggests, with altcoins at +0.61% beating both majors. A fading squeeze typically bleeds the long tail first while BTC holds on ETF flows, so alts outperforming argues the move is broadening, though one week is not a trend. The flow broadening extends beyond the majors too, with SOL and XRP ETFs both setting 2026 inflow records at $154M and $110M. Looking at DATs, Strategy added a known structural buyer to the mix, raising another $2B on Monday with roughly $1.6B of dry powder now sitting behind, at exactly the moment ETF demand printed its first negative day.

Our take:

Under-allocated investors are providing price support here, with $75k and $82k as two key levels into the FOMC mid September"

Short-term direction is genuinely hard to call here, and what matters more is that the ETF bid stays constructive, since flows are what turned the tape in the first place. The initial bounce was heavily a debasement trade, visible in the gold-BTC correlation snapping back, and Warsh's hawkish Jackson Hole took some of that narrative away without taking the levels away, so the market now sits significantly higher with its original story diluted. What holds it up instead is positioning, because consensus has moved to late-stage bear market at minimum and a significant share of investors still feels under-allocated.

That sets up the two paths from here. The bull case is that offside investors keep chasing and FOMO does the work of the narrative. The healthier case is that leverage cools and BTC retests the mid-$70s, a deleveraging that would clean the base before higher levels. On the upside, $82k has now been tested a few times and keeps meeting supply, while $75k and $72k are the supports below, and a break of $72k leaves no obvious floor to point to.

Traders are officially back with September upon us, and the next two weeks decide the direction, but the real catalyst is the FOMC on 15-16 Sept, with Warsh silent on guidance until then. The view fails if ETF flows turn negative on the week or $72k gives way on a weekly close, and until the rate decision clears, chop on both sides of this range is the base case rather than the exception. Payrolls Friday 4 Sept is the one print before then that can move hike odds meaningfully from the current 62%.
