Risk premium moves to the core: CDS widened in all 14 of the 14 countries reporting on 21 September, and France overtook Italy
Open the report ›Scenario
Confirmed
The published claim
H1 · 50% — Synchronised tightening, premiums in a high band: energy stays high, developed and emerging-market premiums settle at 21 September levels, and France stays above Italy.
What happened
The direction held, but the level proved harsher than expected. Premiums did not stabilise on 21 September; they widened further. France's 5-year CDS rose from 47.19 on 21 September to 57.42 basis points on 24 September. Italy stayed at 45.12 the same day, so France remained above Italy. Germany rose from 8.49 to 9.50, and Türkiye from 242.43 to 245.17.

The published claim
H2 · 30% — Energy retreats, premiums narrow: Brent settles well below 100 dollars, part of the 21 September widening is reversed, and Türkiye's CDS could return to around 230.
What happened
The trigger did not materialise. Instead of falling below 100 dollars, Brent rose to 106.60 dollars on 24 September and again topped 106 dollars at the Asian open on 28 September. Türkiye's CDS did not return to 230; on 25 September it crossed 250 for the first time since 27 May.

Partly borne out
The published claim
H3 · 20% — A break at the core: the France–Germany spread exceeds 110 basis points and France's CDS passes 50; the ECB is caught between fragmentation risk and tightening.
What happened
Half of the trigger materialised. France's 5-year CDS rose above 50, to 55.98 basis points on 23 September and 57.42 on 24 September. Sources diverge on the France–Germany 10-year spread. Calculated from 28 September closes (France 4.78%, Germany 3.63%), it is about 115 basis points, while another provider gives 105.4 for 25 September. We could not verify with a single consistent series that the threshold was crossed. Nor is there any record of the ECB changing policy in response to fragmentation risk.

Confirmed
The published claim
Threshold: Türkiye's CDS exceeding 250 basis points would show the Turkish premium moving beyond the bloc-wide move, with country-specific pressure added.
What happened
The threshold was crossed on 25 September, when Türkiye's CDS rose above 250 for the first time since 27 May. The source of country-specific pressure was also clearly visible: the liquidation of 131 funds worth about 18 billion dollars and a widening fund investigation.

Confirmed
The published claim
Threshold: the US 10-year yield exceeding 5.05% would show the dollar discount rate moving into a new, higher band.
What happened
The threshold was crossed on 23 September. After hot PMI data, the 10-year yield rose to 5.10%, its highest level since 2007. The same day the US Treasury sold 5-year notes at 5.033%.

Partly borne out
The published claim
First link in the chain: tightening is written at the front end; the problem lies in price, not demand. The reading that 'yields are rising because demand is weakening' was flagged as noise.
What happened
The price leg held, but we were wrong on demand. The 5-year auction cleared at 5.033% and the 7-year auction on 24 September at 5.085%, the highest rate since April 1993. Yet indirect demand at the 7-year auction fell to 57.2%. In Germany, a 5 billion euro Bobl auction on 23 September drew bids of only 4.53 billion. Weak demand was not noise but a second signal.

Still open
The published claim
Thresholds: Japan's 30-year yield exceeding 4.21% and Germany's 30-year yield exceeding 4.00% would show tightening moving out to the long end.
What happened
Neither threshold has yet been crossed. Japan's 30-year yield closed at 4.16% on 25 September and Germany's 30-year yield at 3.91% the same day. The check has not yet matured; the verdict is deferred to the next review.
What we learned
The report read the direction correctly but was wrong in two places. First, we expected premiums to stabilise at 21 September levels; instead the widening continued and Türkiye added a country-specific channel. Second, we treated weak auction demand as noise. The US 7-year and German 5-year auctions showed that demand was also eroding. From now on, when reading auctions we will record price and demand as separate signals.
