Headline CPI rose to 3.7% from 3.4% in August, with core printing +0.3% m/m against 0.2% expected, which raised the concern that higher energy prices are now spilling into core. As a result, Brent and U.S. Treasuries were the only winners on the week, the latter because the AI trade wobbled at the same time and pushed money out of crowded growth names.
The Treasury rally was a rotation bid and not a change in the inflation view, since the 10-year had been climbing toward multi-year highs earlier this month on sticky inflation and a more hawkish Fed. FedWatch has a hike at next week’s meeting at 15-17%, with a hold as the base case and a cut off the table, while a hike is priced for December only.
That pricing assumes the Fed sits through the midterms on 3 November and then moves, which we think is too convenient with core running hot and energy rising. A hawkish hold on 28 October would pull it forward and push the 10-year back up, which is how the rotation bid unwinds.
Crypto’s macro correlation has been rising again over recent weeks, so the 10-year and the AI trade now feed directly into the digital asset picture below.
Digital Assets
Bitcoin is defending $82.5k, the level that was resistance on the way up and now looks like support, after trading around it for over three weeks. It briefly looked lost last week before BTC reclaimed it and closed back above. The Fed next week, the midterms and Q3 earnings all land in the next few weeks, and we don’t think the range holds through them. A push through the $87k highs is the breakout, while a clean loss of $82.5k would turn the flipped support back into resistance and put the low $70ks in play. Direction is hard to call, but a range this compressed ahead of that many catalysts points to volatility returning.
The bull case rests on technicals and a cycle-reset argument, both of which largely fall apart on a break lower. The bear case goes over sticky inflation, higher yields and the AI wobble, but Bitcoin’s 3.5-point lead over the Nasdaq shows it holding up better than the macro tape would suggest. We flag that the AI funding worries (tokens, energy, capacity, revenue models) will stay in the background until Q3 earnings show a miss on the top or bottom line.
Altcoins are starting to feel heavy again, with the whole spectrum cohort selling off since topping around 14 days ago and down 5.69% on the week. The usual high-beta and micro caps are seeing the most pressure, as the exhibit below shows.
We are seeing the same on the desk, with two main observations:
As a result, the risk reward looks more compelling in majors than in altcoins right now. BTC and ETH can go either way, while alts are likely sideways if BTC rips and lower if the entire market sells off.
This is also visible in the intra-correlation across the top 50, 100 and 250. Correlation rose together during the initial rally in August and September, then decoupled into something of a stock-picker environment, where idiosyncratic headlines drove individual token performance. What goes up together comes down together, and the exhibit below shows correlation climbing again as the market sells down, to levels close to the rally peak.
Our take:
“Implied vol is cheap into the Fed and the midterms, we expect the $82.5k range to resolve soon without calling the direction"
The 28 October FOMC is the likeliest point for the break, and it cuts both ways. A hawkish hold would pull the December hike pricing forward and push yields higher, which pressures the Nasdaq and tilts Bitcoin lower. A measured Fed alongside a Q3 earnings beat would ease that pressure and give the bull case room to push through $87k. Implied vol is still low against compressed realized vol, and that gap closes when the range resolves, whichever way it goes.
Key dates are the FOMC decision on Wednesday 28 October and the midterms on Tuesday 3 November, with Q3 earnings running through the period.
