Core inflation comes in higher than the prior reading.
Why: Core strips out food and energy, so a move in it signals persistent, broad price pressure rather than a one-off in volatile items — the kind a central bank reacts to.
The market reprices the policy-rate path higher.
Why: If inflation is stickier than thought, the central bank must keep rates higher for longer to cool it; traders bake that expectation into the whole rate curve immediately, before any actual hike.
Real yieldsreal yield — The yield after subtracting expected inflation — what a lender actually earns in purchasing power. Real yield ≈ nominal yield − expected inflation. rise, not just nominal yieldsnominal yield — The headline interest rate on a bond, before subtracting inflation..
Why: The inflation is already in the print, so the jump in nominal yields isn't just compensating for higher inflation — it's a genuine rise in the inflation-adjusted return demanded by lenders.
A higher real yield is a higher discount ratediscount rate — The rate used to convert a future cash flow into today's value. A higher discount rate makes far-off cash flows worth less now. on future cash flows.
Why: Money earned years from now is discounted back to today at the real rate; when that rate rises, distant cash flows shrink in present-value terms more than near ones.
Long-duration growth equities de-rate hardest; banks and value hold up; the currency firms.
Why: Growth stocks are valued mostly on far-future profits, so a higher discount rate hits them most. Banks earn more as rates rise (wider margins), and value/cyclical earnings sit nearer in time. Higher local rates also pull in foreign capital, lifting the currency.

Caveat: Misfires if the print is read as one-off/transitory, or if growth is simultaneously rolling over (a stagflation mix), where cyclicals don't get the usual lift.

What would change the read

Inflation surprise (downside / disinflation) Core inflation isn't cooling fast enough to trigger the disinflation channel. A fall of ≥0.2pp would fire it — worth watching because it is the cleanest tailwind for long-duration growth and government bonds.
Monetary easing (rate cut) The policy rate is on hold, so the easing channel is dormant. A cut would fire it — it matters because the first cut of a cycle typically broadens a rally and pressures the currency.
Monetary tightening (rate hike) The policy rate is steady, so the tightening channel is dormant. A hike would fire it — watch it because it hits long-duration growth, long bonds, and gold first.

Monetary tightening (rate hike) The policy rate is steady, so the tightening channel is dormant. A hike would fire it — watch it because it hits long-duration growth, long bonds, and gold first.
Growth acceleration (expansionary PMI) Manufacturing isn't both expanding and accelerating, so the growth-acceleration channel is dormant. A rising PMI back above 50 would fire it — it matters because it's the signal to rotate from defensives toward cyclicals.

M9Long-end yield spike / term-premium rise

Trigger: yield_10y: 0.204919 → 0.377151 (+0.172232)

⚠ Fired on a stale print: yield_10y as of 2021-05-01 (22d old). The change may predate current conditions — treat as provisional.

The 10-year yield jumps.
Why: The long yield sets the cost of long-term money for the whole economy and the discount rate for the longest cash flows.
The discount rate on all long-dated cash flows rises.
Why: Equity valuations and long-bond prices are present values of distant cash flows; a higher long yield shrinks those present values.
Long-duration growth equities compress, long bonds fall, gold is pressured.
Why: The longest-duration assets are most exposed to the discount-rate move, and a higher real yield raises the opportunity cost of holding non-yielding gold.

Caveat: Granularity is daily, so a single-session jump can be noise; a sustained multi-session move is the real signal. Distinguish a growth-driven rise (risk-on) from a supply/term-premium rise (risk-off).

M2Inflation surprise (downside / disinflation)

Trigger: core_cpi: 0 → -1.2 (-1.2)

Core inflation falls more than the prior reading.
Why: A faster-than-expected cooling in the persistent part of inflation tells the market the central bank has more room to ease.
The market prices an earlier or deeper easing path.
Why: Lower inflation removes the reason to keep rates high, so traders pull forward expected cuts into the curve.
Real yields fall.
Why: The expected policy ratepolicy rate — The interest rate a central bank sets directly (e.g. the Fed funds rate, the ECB deposit rate, China's LPR). It anchors all other rates. drops while inflation expectations stay anchored, so the inflation-adjusted return demanded by lenders declines.
A lower discount rate re-rates long-duration assets upward; long bonds rally.
Why: Future cash flows are now discounted less harshly, lifting growth equities most; bond prices rise mechanically as their yields fall.

Caveat: Misfires if disinflation is driven by demand collapse rather than supply normalization — then the growth scare dominates and risk assets fall despite lower yields.

House-view hook — empty (textbook default; Stephen's view bakes in here).

What would change the read

Inflation surprise (upside) Core inflation is steady, so the upside-surprise channel is quiet. It would fire on a core reading ≥0.2pp above the prior — watch it because that is what forces a central bank to stay restrictive and pressures the longest-duration assets first.
Monetary easing (rate cut) The policy rate is on hold, so the easing channel is dormant. A cut would fire it — it matters because the first cut of a cycle typically broadens a rally and pressures the currency.
Monetary tightening (rate hike) The policy rate is steady, so the tightening channel is dormant. A hike would fire it — watch it because it hits long-duration growth, long bonds, and gold first.

Concept libraryL3

Terms marked ✓ are linked inline above — click any dotted term in the text to expand it in place.

2s10s: The gap between the 10-year and 2-year government bond yields. Positive = normal upward-sloping curve; negative ('inverted') = a classic late-cycle/recession warning.
PMI: Purchasing Managers' Index. Above 50 = the sector is expanding vs last month; below 50 = contracting. A timely read on activity.
carry trade: Borrowing in a low-rate currency (long the yen's case) to buy higher-yielding assets elsewhere. It unwinds violently when the funding rate rises or the funding currency strengthens.
credit impulse: The change in the flow of new credit into an economy. A rising impulse front-runs stronger demand for commodities and cyclical goods, with a lag.
cyclicals: Sectors whose earnings rise and fall with the economic cycle — industrials, materials, energy, consumer discretionary.
defensives: Sectors whose demand is steady through the cycle — consumer staples, utilities, healthcare. They outperform when growth slows.
discount rate ✓: The rate used to convert a future cash flow into today's value. A higher discount rate makes far-off cash flows worth less now.
disinflation: Inflation that is still positive but falling (prices rising more slowly) — distinct from deflation, where prices actually fall.
duration: How sensitive an asset's price is to interest rates. 'Long-duration' assets (long bonds, fast-growing stocks whose profits are years away) move most when rates change.
net interest margin: The spread a bank earns between what it charges on loans and pays on deposits. Higher short rates / steeper curves tend to widen it.
nominal yield ✓: The headline interest rate on a bond, before subtracting inflation.
policy rate ✓: The interest rate a central bank sets directly (e.g. the Fed funds rate, the ECB deposit rate, China's LPR). It anchors all other rates.
rate path: The market's expectation of where the policy rate goes over the next year or two — not just today's level, but the whole expected trajectory.
real yield ✓: The yield after subtracting expected inflation — what a lender actually earns in purchasing power. Real yield ≈ nominal yield − expected inflation.
term premium: The extra yield investors demand to hold a long bond instead of rolling short ones — compensation for tying money up and for issuance/inflation risk.
