The Month in Brief
September turns the rate debate into a decision. Futures pricing puts a quarter-point increase at the 15–16 September meeting at 66.1 percent, against 33.9 percent for no change and zero for a cut (CME FedWatch, read 31 August). The meeting carries a Summary of Economic Projections, so the committee has to publish a rate path alongside whatever it does.
Two prints stand between here and there: the August employment report on 4 September and the August Consumer Price Index (CPI) on 11 September. The sequence then runs the decision and consumption together on 16 September, and the Federal Reserve’s preferred inflation gauge on 30 September, the same morning federal funding lapses without a continuing resolution.
For cryptocurrency, the constructive path is a labour market soft enough to take the increase off the table while inflation cools on its own. That would let the 10-year real yield fall away from the 2.5 percent line we have flagged as the level that would break the bitcoin case. The hostile path is an increase delivered into an economy that markets still read as strong, which lifts real yields and the US dollar together.
September Catalyst Calendar
| Date | Release or Event | Why It Matters |
| Tuesday, 1 Sep | ISM Manufacturing PMI, 10:00 am (ISM); JOLTS, July, 10:00 am (BLS) | Prices-paid gauge and the vacancy-to-unemployed ratio open the month; ISM services follows on Thursday 3 September |
| Friday, 4 Sep | Employment Situation, August, 8:30 am (BLS) | Payrolls fell 23,000 in July with May and June revised down by a combined 103,000; a second negative month is the strongest argument against an increase |
| Wednesday, 9 Sep | First enlarged Treasury liquidity support buyback, 10-year to 20-year sector (Treasury) | Operations in the two longest nominal buckets double to at least $4 billion each, running through 4 November; the test is whether the long end responds |
| Thursday, 10 Sep | PPI, August, 8:30 am (BLS); ECB decision and press conference, Berlin (ECB) | Producer prices give the first refresh of the computing-equipment lines behind the AI inflation channel |
| Friday, 11 Sep | CPI, August, 8:30 am (BLS); University of Michigan preliminary sentiment, 10:00 am (U-Mich) | The last inflation print before the decision, and the one that decides whether core CPI is converging on core PCE or diverging from it |
| Tuesday, 15 Sep | FOMC meeting begins (Fed); Senate cloture vote on the motion to proceed to H.R. 3633, the Digital Asset Market Clarity Act (Congress) | Crypto market-structure legislation faces a 60-vote threshold on the same day the committee sits down |
| Wednesday, 16 Sep | FOMC decision and Summary of Economic Projections, 2:00 pm (Fed); Advance Retail Sales, August, 8:30 am (Census); Import and Export Price Indexes, August, 8:30 am (BLS) | The decision, the new rate path and the cleanest read on consumer demand all land in one session |
| Thursday, 17 Sep | New Residential Construction, August, 8:30 am (Census); Bank of England Bank Rate (BoE) | Housing supply against a 30-year yield above 5 percent; no Monetary Policy Report accompanies the UK decision |
| Thursday, 24 Sep | New Residential Sales, August, 10:00 am (Census) | July new home sales fell 10.5 percent to 607,000 annualised with 9.6 months of supply; the follow-through tests whether housing breaks first |
| Friday, 25 Sep | Advance Report on Durable Goods, August, 8:30 am (Census) | Core capital goods shipments carry the AI capex signal into third-quarter growth tracking |
| Tuesday, 29 Sep | Conference Board Consumer Confidence, 10:00 am (CB); JOLTS, August, 10:00 am (BLS) | Confidence has softened for two straight months to 89.4; the labour differential is the forward-looking piece |
| Wednesday 30 Sep | Personal Income and Outlays, August, and GDP third estimate, second quarter, 8:30 am (BEA); federal funding lapses without a continuing resolution (Congress) | Core PCE is the gauge the Federal Reserve targets, and it lands two weeks after the decision; no FY2027 appropriations bill has been enacted |
Our Views and What Would Prove Them Wrong
In Bitfinex Alpha Issue 220 we set out our current views alongside the conditions that would prove each of them wrong. September provides a scheduled test for every one of them, and one has already been overtaken by the pricing.
| Our View | Where It Stands | September Test and What Would Break It |
| The hold has become a hawkish hold with live hike risk | We carried a trapped hold from late July. It no longer describes the pricing. The FOMC held the target range at 3.5 to 3.75 percent on 29 July on a 9 to 3 vote, with three dissents in favour of an increase, and the statement called inflation elevated and dropped its two-sided risk language. The Chair then used Jackson Hole to restate the 2 percent target as a hard constraint. Hike pricing for 16 September has run from 44 percent in mid-August to 57.0 percent on 29 August to 66.1 percent on 31 August (CME FedWatch). | The view breaks if hike pricing falls back below 40 percent and stays there into the meeting, which would need a clearly negative payroll print on 4 September or a soft CPI on 11 September. It breaks in the other direction if the committee raises rates and the Summary of Economic Projections shows a median path with further increases, which would make this a tightening cycle rather than a hawkish hold. |
| The bitcoin tailwind holds while the 10-year real yield stays below 2.5 percent | The 10-year real yield closed at 2.42 percent on 28 August, up eight basis points on the day of the Jackson Hole speech from 2.34 percent on 27 August (Treasury, DFII10). Eight basis points from the line. | Breaks if the real yield closes above 2.5 percent for two consecutive weeks rather than merely touching it. The CPI on 11 September, the decision on 16 September and the PCE report on 30 September are the likeliest trigger dates. |
| The long end is capped for now, and the buybacks are the reason to test it | The 30-year yield closed at 5.22 percent on 28 August, unmoved by the speech, against an earlier high of 5.31 percent (Treasury). Treasury has doubled its long-end liquidity support operations from $2 billion to at least $4 billion each, effective 9 September through 4 November, citing the volume of high-quality offers it routinely receives (Treasury). | Breaks if the 30-year sets a new closing high above 5.31 percent in a week that contains a buyback operation, which would say the operations are being absorbed rather than supporting the sector. |
| The labour market is cracking while claims stay low | Payrolls fell 23,000 in July, May was revised down by 66,000 to 63,000 and June down by 37,000 to 20,000, yet initial claims were 203,000 in the week ending 22 August, with a four-week average of 205,500 and an insured unemployment rate of 1.2 percent (BLS, DOL). Unemployment held at 4.1 percent and participation at 61.4 percent, down 0.7 percentage points since January. | The 4 September report decides whether July was the first of two consecutive negative months. The low-claims leg breaks if initial claims top 230,000 in two consecutive weekly prints. Watch participation: a falling rate is what holds the unemployment rate at 4.1 percent while hiring stalls. |
| The two core inflation gauges disagree, and the one the Federal Reserve targets is the higher one | Core PCE rose 3.3 percent in the year to July while core CPI rose 2.5 percent (BEA, BLS). Headline PCE was 3.7 percent and headline CPI 3.4 percent, with energy up 14.7 percent year on year doing most of that work. Monthly core was 0.2 percent on both gauges. | The PPI on 10 September and CPI on 11 September test whether core CPI is drifting up toward core PCE or the gap is widening. Breaks if core PCE on 30 September falls below 3 percent, which removes the strongest single argument for an increase. |
| The diesel shock is intensifying, not fading | Retail on-highway diesel averaged $5.652 per gallon on 24 August, up 19.8 cents on the week and $1.944 higher than a year earlier (EIA). In late July it was near $5.13. CPI energy rose 14.7 percent in the year to July even as it fell 1.5 percent on the month. | Breaks if retail diesel retraces below $5.00 per gallon and distillate stocks rebuild toward the five-year average before the 11 September CPI. The Monday retail price series and the Wednesday EIA report track it. |
| The AI build-out is an inflation story, not only a growth story | Import prices for capital goods rose 0.9 percent in July, with higher prices for computers, peripherals and semiconductors named among the drivers, even as total import prices fell 0.4 percent on the month (BLS). | The PPI on 10 September and the import and export price indexes on 16 September are the two price refreshes. Durable goods on 25 September and the GDP third estimate on 30 September update the capex side. Breaks if computing-hardware prices flatten for two consecutive months while capex guidance holds. |
| The consumer is funded but no longer growing in real terms | Real consumer spending was essentially flat in July, up less than 0.1 percent, while the personal saving rate rose to 3.0 percent (BEA). University of Michigan sentiment was 51.7 in August and Conference Board confidence 89.4, softer for a second month (U-Mich, CB). New home sales fell 10.5 percent in July to 607,000 annualised. | Retail sales on 16 September: watch the control group over the headline, noting it is a nominal series, so fuel-driven price rises can flatter it. Then confidence on 29 September and inflation-adjusted spending inside the 30 September PCE report. Breaks if real spending turns negative for two consecutive months. |
| Bitcoin trades on macro, not on flows | Bitcoin traded near $78,100 on 31 August. US spot bitcoin ETF inflows ran above $3 billion across August and the crypto stablecoin float expanded to roughly $304 billion, yet the complex did not join the equity risk rally. Positioning data as reported in Bitfinex Alpha Issue 220 (31 August) except where dated. [DATA NEEDED, ANNE: current on-chain level set to replace the Issue 215 levels, which are stale at $78,000 spot. Short-term holder cost basis, the URPD shelves above and below, and the realised price.] | Expect the sharpest reactions on the day after each tier-one print: 7 September (post-payrolls flows), 14 September (post-CPI), 17 September (post-decision) and 1 October (post-PCE). Breaks if bitcoin sustains a move against the direction of the 10-year real yield across two consecutive tier-one prints. |
| The fiscal calendar is now a data risk, not only a supply risk | No FY2027 appropriations bill has been enacted. The House has passed a continuing resolution funding the government to 4 December and the Senate an alternative to 11 December, and funding lapses after 30 September without agreement (Congress). | A lapse would suspend BLS and Census releases, which would leave the committee going into the 27 to 28 October meeting without the September data and possibly the October data. Breaks if a continuing resolution is enacted before 30 September, which pushes the same risk out to December. |
Scenario Matrix
| Macro Combination | Rates and US Dollar | Likely Crypto Interpretation |
| Negative payrolls on 4 September and a soft August CPI | Hike pricing collapses; yields and the US dollar lower | Most constructive; the real yield falls away from 2.5 percent and the bitcoin tailwind strengthens |
| Firm payrolls and firm CPI, increase delivered on 16 September | Front end higher, dollar firmer, long end capped by buybacks | Negative; the real yield likely breaches 2.5 percent and starts the two-week clock |
| Increase delivered, but the projections present it as the last one | Curve steepens as the terminal rate is capped | Negative on the day, supportive afterwards if the dollar fades |
| No increase, but the projections keep one in reserve | Pricing rolls forward to 27 to 28 October | Relief without resolution; the same test returns in six weeks |
| Weak payrolls with firm inflation | Real yields stay elevated on a weaker growth path | The most difficult combination for risk assets |
| Funding lapses on 1 October | Data blackout and term premium noise | Removes the inputs both the committee and the market use, widening the distribution of October outcomes |
Bottom Line
September puts the increase on the table as a live decision. The pricing has already overtaken our hold view, so we carry it forward as a hawkish hold with live risk of an increase, and we have said what would retire even that.
The bitcoin case now rests on eight basis points of the 10-year real yield. The long end rests on whether doubled Treasury buybacks can absorb the supply they are meant to support. The consumer is funded and has stopped growing in real terms, without yet contracting.
Each of these has a dated test this month. The last of them, on 30 September, lands the same morning federal funding runs out. We set these conditions out in advance so that the data decides which views survive into October.
Payrolls > CPI > FOMC and Projections > Retail Sales > PCE Inflation > Funding Deadline
