How to read this. This report uses data as of October 6, 2026. Published reports are not rewritten; corrections are recorded in later issues.

proxy-GRCS was first calculated at 76.3 (88.5th historical percentile). For publication we recalculated it using one source across the full period and show 74.1 (82.4th percentile). The difference is explained under Judgmental and objective compared.

Line chart of the three main indices in 2026
Figure 1. The three main indices. GRCS5 and FFI are high and FCO is low. All use the same 0-100 scale on one axis.

The point to note is that the price layer alone has moved for the first time, while high macro pressure and low financial stress continue side by side. The move was not large enough to change the FCO band.

Regime reading

The regime for September is Compound Macro Stress / Latent Fragility. It meets the conditions of GRCS5 at 75 or more, FFI at 65 or more and FCO below 30. This reading has held since April, 6 months in a row.

Why the scores moved

Volume and price at Hormuz moved in opposite directions. Weekly transits recovered to 82 and 95, and crude flows were about 7.4 million b/d, about 40% of the prewar level of about 20 million b/d. Brent still rose sharply, ending the month near $107.

Three-layer check of financial contagion

We check financial contagion in three layers: price, credit and leverage, and plumbing. This month the three layers gave different results.

The price layer moved. The widening in HY OAS came mostly after 2.73% on September 23. HY issuance of $38.5 billion was the largest of the year, and CCC spreads of 968bp were the widest since November 2023. Poor digestion of new supply and selection by quality appear to be behind this.

The credit and leverage layer stays loose. NFCI credit is −0.06 and NFCI overall is −0.56. However, NFCI nonfinancial leverage keeps rising, to −0.47, which is the 93rd percentile since 2010.

The plumbing layer is normal. SOFR−IORB is 0bp and Fed lending is $8.8 billion, with no strain visible after the hike.

Credit, volatility and intervention use are calculated mechanically. Funding, banks and liquidity are scored by expert judgment. We raised liquidity from 0 to 5 to reflect poor digestion in the HY market.

Breakdown of FFI

Leverage and credit quality0.207374
Maturity wall0.156769

Opaque assets0.207373
Bank lending standards and balance sheets0.105757
External vulnerability (EM)0.156972
FFI1.0071.1071.45

Leverage and credit quality rose from 73 to 74, the maturity wall from 67 to 69, and external vulnerability from 69 to 72. Valuation fell from 79 to 76 as spreads widened. FFI treats spread compression as adding to fragility, so widening lowers this score.

Social unrest and regional conflict

Countries with SURI ≥ 60 rose from 10 to 12. The new ones are Bangladesh (60.75) and Peru (60.05), both barely over the line. Countries at 75 or more stay at five, with Myanmar just below at 74.90. The simple average rose from 62.67 to 63.79 and the population-weighted figure from 63.34 to 64.46. The population-weighted figure exceeds the GDP-weighted one, so pressure is concentrated in populous low-income countries.

This month's scoring added 2 to household stress in all 20 countries, a further 1 in the 13 countries dependent on Black Sea wheat and net fuel imports, 1 to protest in the 6 countries already at 70 or more, 1 to government fragility in the 11 countries dependent on external funding, and 1 to conflict in Lebanon.

RCEI rose from 77.85 to 80.70, led by combat intensity, escalation speed, and food, energy and water.

Strength of the chains

SCI rose from 78.8 to 82.0. Chain 2 reached the ceiling of 5.0 from 4.9, Chain 4 rose from 4.0 to 4.2 and Chain 1 from 4.2 to 4.4. Only Chain 1 has support from 30 years of data; the rest are structural reasoning.

Judgmental and objective compared

We compare judgmental GRCS4 with proxy-GRCS, calculated mechanically from markets and statistics. September rose on the objective measure too. In percentile terms there are two peaks, March to May (82-88) and September (82), with June to August in the middle (53-58). The judgmental score has risen every month since January. This difference in shape suggests a possible upward bias in judgmental scoring.

About the unified value. The original 76.3 used the World Bank Brent ($116.8), the preliminary GPR (146.2) and August CPI. The historical series used IMF Brent ($102.02 in September) and a more settled GPR (155.9), so September alone mixed sources. With the IMF source across the full period the value is 74.1 (82.4th percentile). The percentiles of the four axes are food 43.9, fiscal 64.7, energy 73.1 and geopolitics 92.1.

As a result, the gap first stated as +13.0 becomes +15.2 and passes the ±15 threshold. We will review the scoring criteria in the next issue. Also, 74.1 sits just below the 75 guide for high pressure, so statements treating September as a high-pressure month should be read with that caveat.

The hypothesis under test

From this month's results we take up the following hypothesis for testing. It is not a conclusion.

"The macro shock has begun to reach financial asset prices through the interest rate channel but has not reached the functions of the financial system. The latter likely reflects the capital and liquidity of financial institutions, but risks that price indexes capture poorly, namely borrower leverage and unrealized losses on bank bond holdings, are building up."

HypothesisStatementCurrent status
H1Macro pressure is risingSupported on judgment. The objective measure rose again but only to March-May levels, near the high-pressure threshold
H2It has not reached financeSupported for plumbing and credit conditions. The price layer began to give way in September for the first time
H3The reason is financial strengthUnresolved, low confidence

To tell these apart, we added falsification conditions to the prediction log: P-16 (strain in plumbing), P-17 (NFCI above 0) and P-18 (STLFSI4 above 0). P-18 alone is consistent with the hypothesis. If P-16 also occurs, the strength depended on intervention. If P-17 occurs, the core of the hypothesis needs revision. If nothing happens, the result is consistent, but financial strength cannot be told apart from a weak causal link.

From the start of rate hikes in 2022 to the failure of SVB took about 12 months. We treat the next 12 months as the test period. See Model Validation for details.

Prediction log

Each prediction is recorded with the probability at issue and judged when due. P-16 to P-18 test the hypothesis. A threshold prediction is settled when reached; P-11 stays settled at the time of publication even if a later revision lowers the value.

5 predictions have been judged, and all were hits. The average Brier score is 0.338, worse than the coin-flip value of 0.25. A hit still scores badly when the stated probability was low. Misses are not counted until their deadlines arrive, so the hit rate at this point looks better than the true skill.

What to watch next month

In September only condition ③ of the five was met. FCO has risen for one month and is far below 30. Chain 1 is at 4.4, approaching 4.5.

ConditionThis monthStatus
① FFI stays above 7571.45Not met
② FCO rises two months in a row and exceeds 305.34 (up 1 month(s) in a row)Not met
③ GRCS4 exceeds 8589.28Met
④ SURI ≥ 60 exceeds 12 countries12Not met
⑤ Chain 1 reaches 4.54.4Not met

If two or more are met at once, we consider a regime change.

From September we also monitor the rate channel through three series: SOFR−IORB, NFCI overall and Fed lending. FDIC third-quarter data, due in late November, will show unrealized losses on bank bond holdings.
