The two-year Treasury yield printed 4.15% on August 13 against 4.26% on July 28. Over the identical window the 10-year moved two basis points, to 4.63% from 4.61%. Eleven basis points came out of the front leg and almost nothing happened at the back, so the curve steepening of the past fortnight belongs to the short end.
The decomposition that was missing
That settles an argument this desk left open at the end of July. The 10s2s spread had jumped to 0.45 on July 29 from the 0.35 implied by the July 28 pair, ten basis points in a single session, and neither leg carried a print for that date. Either the two-year had rallied or the 10-year had sold off, and the available data could not say which. Cut pricing went into the book as a low-probability thesis for that reason and no other. August answers it. The short end rallied, and by enough to matter.
The spread has widened a shade further since, T10Y2Y at 0.51 on August 14 against the 0.48 implied by the August 13 pair of legs. Those last three basis points come without prints of their own, so they stay undecomposed. Same gap as before, smaller.
No fear in the bid
Duration gets bought for two reasons that mean opposite things. One is a growth scare, where the front end rallies because the Fed is about to be forced into something. The other is disinflation, where the front end reprices a slower policy path with the economy intact. Monday's tape argues hard for the second.
VIX read 15.17 on Monday, up 6.46% from 14.25 the day before. Against 20.66 on July 29, that is more than five points of implied vol gone since late July, and the one-day rise leaves it in the mid-teens. A front end taking eleven basis points off while vol sits there is not a flight to safety.
The equity cross-section says the same thing more bluntly. Measured from Friday's closing marks into Monday's session, Caterpillar rose 3.46% to $886.25 and Freeport-McMoRan added 2.90% to $68.42, while Meta fell 3.74% to $567.80 and Microsoft fell 3.14% to $479.82. Machinery and copper bid; two of the largest megacaps sold. Growth scares do not hand the leadership to cyclicals.
The crude is the problem
Brent marked $90.90 in Monday's session, up 2.69% over twenty-four hours from $88.52. WTI rose 2.67% to $84.60 across the same window, and USO gained 2.35% from its Friday mark. On Monday's matched marks the Brent-WTI spread is 6.30, against the 5.84 recorded on the matched July 29 marks.
The composition deserves care. Brent and WTI rose by almost exactly the same percentage on Monday, 2.69% against 2.67%, so the session itself says little about which grade is leading, and a spread of 6.30 against 5.84 partly reflects a higher price level rather than a fresh widening of the risk premium. What it does not show is decay. The seaborne premium that this desk has read as the market's answer to the July 7 tanker strike near the Strait of Hormuz is six weeks old and still there.
Set that against the realised price data. CPIAUCSL reads 332.813 for July against 332.568 for June, a rise of 0.07% in the index level after June's outright decline of 0.42%. Small, and one month is one month. The sign has flipped.
June's cooling was real: year-over-year CPI at 3.53% against 4.25% for May, 72 basis points in a single month. It was also recorded with WTI at $70.56 on June 30 on the FRED series. The live mark is $84.60 on a different series, and this desk's own July work put the two sources between $83.43 and $84.25 on the same day, so treat the gap as directional rather than exact. Directionally it is very large.
The front end, in other words, is pricing relief into an input that is moving the other way.
Where the argument could break
Eleven basis points is a small move, and a committee is allowed to look through headline energy. If core keeps cooling, a hold that opens the door to a cut is coherent even with Brent at $90.90, which is why the July book gave the disinflation branch 30 out of 100 rather than dismissing it.
There is a harder problem with reading the two-year as cut pricing. No real-yield observation in this book postdates DFII10 at 2.41% on July 28, and there is no two-year real series at all, so the eleven basis points cannot be split into a real leg and an inflation-compensation leg. If compensation did the work, the front end is not pricing a cut, it is pricing less inflation, and those are different statements with different trades attached.
The trigger set in late July was itself a two-legged condition, and only one leg has cleared. It called for a DGS2 print below its 4.26% July 28 level with DGS10 holding near 4.61%, alongside the July 30 Personal Income and Outlays and Trimmed Mean PCE releases corroborating June's cooling. The yield leg has cleared cleanly, 4.15% against 4.26% with the 10-year at 4.63%. The corroboration leg does not appear in this book, so what exists is one confirmation rather than two, and the thesis should be marked up from low, not marked as settled.
The stated invalidation on the bearish nominal-bond view has not been touched. It reads: DGS10 below 4.25% sustained three or more days together with DFII10 back below 2.20%, its June 30 level, or an August 12 CPI print below 3.0% year over year. At 4.63% on August 13 the 10-year is nowhere near the first leg, and this book carries the July CPI index but no year-over-year figure, so the second cannot be checked here. The oil view's invalidation is equally untouched: Brent below $81.62, its July 21 marker, with the Brent-WTI spread back inside 5.00, or WTI below $70 sustained three or more days. Nothing on Monday's marks is within reach of either.
A dollar reading would help arbitrate between a policy-easing bid and a haven bid. The only observation available is the broad index at 119.0649 on August 7, with no prior print to compare against and on a different gauge from the narrow index quoted in late July. A level, no direction, no help.
Two descriptions, one economy
Cyclicals leading, crude up 2.69% in a day with the Brent spread at 6.30, vol in the mid-teens: that is the reflation branch, weighted at 35 in the July book with an energy-shock tail at 15, half the distribution between them. A two-year at 4.15% describes a central bank with room to ease into falling prices, which is most of the other half.
One of those is offside, and my money is on the yield print. It takes real money rotating between sectors to move machinery and copper by roughly 3% while two of the biggest megacaps drop by roughly 3% over the same days, and that is a broader vote than a single Thursday reading in the two-year. Watch the next DGS2 alongside the next DGS10. If the two-year holds under 4.26% with Brent above $90, the front end has committed to a view on energy pass-through that the July book put at close to even money, and the next inflation print grades it, not this tape.
