Term premium is repricing the long end; we keep the 2s10s steepener into this afternoon's minutes

Both break tests held. We keep the 2s10s steepener: term premium and oil risk sit in the long end, front anchored into this afternoon's minutes.

Duration

The 2s10s spread sat at 52bp on August 18[1], up from 44bp on August 6[2], and the widening is coming from the long end. The 10Y printed 4.72% on August 17[3] against 4.63% on August 13[4], roughly 9bp of selloff, while the front held. EFFR fixed 3.63% on August 17[5] and the target range stayed at 3.50 to 3.75%[6], so front-end policy pricing has not moved with the back. We read the long-end repricing as term premium and keep the 2s10s steepener.

The break tests on record held. The July minutes have not printed, and with the 10Y at 4.72% and 2s10s at 53bp on August 17[7] the 2Y sits below our 4.25% break level. Treasury has not tilted toward coupons either: Monday's record $85B coupon run is mechanical cash flow[8], not a refunding signal.

Funding

Funding firmed at the margin and stayed orderly. SOFR fixed 3.66% on August 17[9], up 4bp from 3.62% on August 14[10], and printed 1bp above IORB at 3.65%[11]. RRP take-up was $0.16bn on August 18[12], down from $0.26bn the prior session[13], and reserves fell to $2.944tn on August 12[14], down $49bn on the week[15]. That reflects cash fully deployed; the overnight read shows no acute pressure[18], aggregate repo volumes up $111bn[16], with the equity repo basis out to +20bp overnight on balance-sheet friction[17].

One issue is trading genuinely special. The February-18-27 bill (912797TV9) drew a SOMA lending fee of 253.6bp against the 5bp program minimum on August 18[19], up from 181.0bp the prior session[20]. That reflects issue-specific collateral demand and stays local to that CUSIP.

Oil and the long end

The overnight risk is in the long end. The US-Iran diplomatic window has lapsed[21], Trump has pivoted to a containment posture on Iran[22], and the diesel crack has spiked[23]; Rabobank flags 30Y yields at 5.31%, the highest since 2007[24]. We treat this as a term-premium and inflation-risk vector that reinforces the steepener.

The alternate read is that an oil shock reprices front-end real rates higher and pulls the front up with the back. The material overnight take makes that case, conditional on supply actually being disrupted[25]. Supply has not been disrupted: China added roughly 200,000 bpd to reserves in July with stockpiles intact through the Hormuz standoff[26], and crude faded the open-strait headline[27]. So we keep the shock in term premium. We're wrong on the anchored-front leg if Hormuz flows verifiably choke and front-end OIS moves up with the back.

Minutes and risks

The July FOMC minutes print this afternoon and are the live catalyst. The trade is off if the minutes push the 2Y through our 4.25% break level and pull the front up with the long end. We keep the steepener into that print and assume Treasury holds its bill-issuance pace through refunding; a coupon-heavy refunding would force a rethink of the long-end leg.

Treasury's buyback bid and a soft 20-year offset; we hold the term-premium steepener

July minutes read marginally dovish, Treasury doubled long-end buybacks, and the 20-year tailed hard; the front end never moved.

Minutes

Today was a duration session, not a policy-path session. The front end never moved: SOFR fixed 3.65%[1] against IORB at 3.65%[2], EFFR held 3.63%[3], and RRP take-up sat at $0.155bn[4]. The July FOMC minutes, out this afternoon, did not change that. They contained hawkish language on upside inflation risks, with AI and tariff pass-through named as live[5], but were sparse on the reaction function, and three dissenters left the committee visibly split[6].

Commentary divided on the read. Some took the inflation language as tilting the risk toward fewer and later cuts[7]; others weighted the three dissenters and softer post-meeting data, clearing the minutes as dovish against hawkish pre-meeting positioning[8]. We hold the latter, because the front end took a bid rather than a selloff and 2Y at 4.19%[9] never approached our 4.25% threshold.

Supply

Treasury doubled the maximum long-end buyback size to $4bn per operation[10], 10y through 30y, effective Sept 9 through Nov 4. The long end rallied on it: 30Y fell 8bp on the day and 2s30s flattened 7bp on the announcement[11]. The market tagged it QE-lite, and we fade the label. These buybacks are Treasury-funded liability management, small against the coupon calendar; the mechanical effect is liquidity smoothing in off-the-runs rather than net duration removal[12].

The 2pm 20-year auction cut the other way. It tailed, bid-to-cover printed 2.53, the weakest since February, and indirect and foreign participation dropped to 62.9% from 69% in July[13]. Real money is not showing up at these levels even with Treasury leaning against the sector, which leaves the term-premium read intact: Brooks decomposes the long-end selloff into stable breakevens and rising real rates[14], a fiscal-risk repricing more than an inflation one.

Positioning

We keep the 2s10s term-premium steepener into tomorrow. The break test on record, that the trade comes off if the minutes push 2Y through 4.25% and pull the front up with the long end, did not trip: the minutes pulled the front lower, and 2Y sits at 4.19% with 2s10s at 52bp[15], near its recent wides. The live risk to the trade is now the buyback, which bids 10y through 30y directly and is the cleanest flattening threat on the board, so we cut size into the Sept 9 rollout rather than add. We're wrong if the buyback durably caps the long end and drags 2s10s back through our 40bp line, or if the front reprices up through 4.25% on a hot jobless-claims print Thursday. This assumes Treasury holds its coupon-issuance pace; a coupon upsize at the next refunding changes the supply math and the trade with it.

Funding

Funding shows no stress. GCF Treasury repo printed 3.667%[18], in line with the past month, and reserves stand at $2.94trln[16], down about $49bn on the week[17] but still abundant. One issue-specific move is worth flagging: the February 18, 2027 bill (912797TV9) went sharply special, its SOMA lending fee jumping to 403.3bp against the 5bp minimum[19], up from 253.6bp the prior day[20]. That is collateral demand for a single CUSIP rather than a broad funding signal. We read the equity repo basis widening to +20bp[21], flagged into month-end, the same way until it persists.
