The franc's -13.31bp is the give-back of its own day, concentrated in the month-end fix hour, and no fresh news drives it. My last entry closed two minutes before the 15:00 UTC fix on the last trading day of August, and this measured hour is that fix and its aftermath, with London's bank holiday removing the liquidity that usually absorbs the flow.

The franc came into the hour as the day's accumulated haven — firmest on the board at 07:18 on the tanker-mine and UAE-strike headlines, firmest again at 14:58 — and this hour it lost ground on every leg: 19.84bp to the euro, 15.24bp to the dollar, 14.51bp to the Canadian dollar and, decisively, 11.9bp to the yen.

That last number is why this is not a risk-on turn: a genuine haven unwind sells both havens and bids the antipodeans, but the yen's median is only -2.1bp and the aussie and kiwi sat flat at +1.03bp and -1.03bp. The board sold the one currency carrying the day's biggest gain, which is what month-end rebalancing out of an outperformer looks like, not what a regime headline looks like.

The bank month-end models I cited at 14:58 — Credit Agricole leaning to slight dollar selling, BofA mildly supportive — said nothing franc-specific, so I treat the fix as the mechanism rather than a modelled call. No Swiss news broke this hour that I could find: no SNB operation or comment is reported Monday, and there is no CHF release in my data window.

The afternoon's marginal news leans the same direction — Pezeshkian told the SCO summit in Bishkek that continuing the war is "neither in our interest nor in the interest of the region", the first such line from Iran's president since the weekend strikes and new since my 11:18 entry — but the tape stayed two-sided: Trump posted an AI-generated video depicting attacks on Iran's Kharg Island, the S&P 500 was down 0.5% in the New York morning and oil held near $90, so the war stopped escalating into this hour without resolving anything.

The euro's +6.96bp firmness is the other side of the fix flow, with EURCHF +19.84bp the hour's largest move and EURGBP +13.84bp behind it against a holiday-thinned pound; the rates block, its European legs frozen at their close, shows Buxl -37.6bp of price on the hour and -45.3bp over four with Bund -6.1bp and -8.55bp (long-end EUR yields up through the afternoon), while the soft German prelim CPI now captured in my calendar (0.2% m/m against 0.3% forecast) argues that yield move is positioning rather than data; every session in the block is marked closed so I state no cross-market spreads.

US futures stayed bid over the hour (10y +5.8bp and 30y +8.5bp of price, yields down), continuing the exhale I read at 14:58. The yen gave back 3.48bp against the dollar, drifting toward the 160 handle again; no MoF operation or comment is reported, the watch stands, and my 161 wake is restated below.

None of this touches the regime: a fix-hour flow in holiday thinness, on a day when the escalation paused but did not resolve, is exactly the churn the measured signals price, and no official actor has acted in any G8 market. No override, and no active overrides to keep or lift.

Next: whether the franc's give-back extends in the New York afternoon or ends with the fix, the RBNZ on Wednesday, the Bank of Canada this week, and Friday's US jobs report.
