Why: Activity is still contracting in absolute terms (below 50), but the rate of contraction is easing — the second derivative has turned up, which historically clusters near cyclical lows.
Forward-looking investors start to price the trough.
Why: Markets discount the turn before it completes; an improving-but-sub-50 PMI often coincides with the low in cyclical risk assets, well before the PMI itself crosses back above 50.

Why: The names most beaten down in the contraction have the most operating leverage to even a marginal improvement, so they re-rate first when the deterioration stops.

Caveat: A one-month uptick that doesn't persist is a head-fake; the turn needs follow-through, and a sub-50 level still means activity is contracting in absolute terms — this is an inflection signal, not an all-clear.

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.
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.

M2Inflation surprise (downside / disinflation)

Trigger: core_cpi: 1.9 → 1.6 (-0.3)

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 yieldsreal yield — The yield after subtracting expected inflation — what a lender actually earns in purchasing power. Real yield ≈ nominal yield − expected inflation. 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 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. 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).

M4Monetary tightening (rate hike)

Trigger: policy_rate: 0.1 → 0.25 (+0.15)

The central bank raises its policy rate.
Why: It lifts the risk-free baseline and signals an intent to drain liquidity to cool demand or inflation.
Discount rates rise; the most rate-sensitive assets are hit first.
Why: A higher risk-free rate lowers the present value of future cash flows, and long-duration growth, long bonds, and non-yielding gold have the most distant or rate-sensitive payoffs.
The currency firms; exporters and dollar-debt EM borrowers are pressured.
Why: A wider yield advantage pulls in capital and strengthens the currency, which hurts exporters' competitiveness and raises the real burden on dollar-denominated EM debt.

Caveat: Late in a hiking cycle, a hike can paradoxically rally bonds if the market reads it as the last one and pulls forward the eventual cuts.

M12BOJ normalization / yen-carry risk

Trigger: policy_rate: 0.1 → 0.25 (+0.15)

The BOJ hikes away from its zero/negative-rate regime.
Why: Japan was the world's last anchor of ultra-cheap funding; raising its rate narrows the gap that made the yen the preferred currency to borrow in.
JGB yields rise and the yen tends to strengthen.
Why: Higher policy rates pull Japanese government bond yields up, and a higher yield plus repatriation flows increase demand for yen.
Yen-funded carry tradescarry 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. unwind, transmitting volatility into global risk assets.
Why: Investors who borrowed cheap yen to buy higher-yielding assets abroad face higher funding costs and a rising yen on their debt, forcing them to sell those assets — so the shock spreads well beyond Japan.

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.
