FX Weekly Update #3 - September 28, 2026

The dollar did the week's work through the bond market rather than any policy event. US yields broke higher — 2-year yields approached 5.00% for the first time in more than two years while the 10-year advanced to 5.20%, the highest since June 2007 — and the Dollar Index cleared 101.00 for the first time since late July, driving fresh cycle lows on Short GBP/USD and Short NZD/USD in the 23–24 September sessions. The SNB held at 0% on 24 September but lifted its conditional inflation forecast for every year to 2028 and restored its standard FX intervention wording, taking USD/CHF to roughly 0.827 and pushing our Long SGD/CHF through both its tactical and strategic objectives. RBNZ Governor Breman warned that persistent oil gains would push near-term inflation above the September Statement's assumptions, and October hike pricing jumped to 75–87% from roughly 20% earlier this month — a hawkish kiwi repricing that our two NZD shorts and Long AUD/NZD now have to survive. Australia's labour report came in mixed — unemployment up to 4.6% against 4.5% expected, with 39,500 jobs added — and yet the RBA is 92–94% priced for a hike on 29 September, with all seven major banks forecasting a move; GBP/AUD rallied into it anyway.


How our views are tracking

Short GBP/USD — thesis strengthened
Sterling fell through our tactical objective even as the 30-year gilt yield rose to 5.90%, which is the terms-of-trade channel our framework prioritised working exactly as specified rather than the rate channel working in reverse.
Long EUR/GBP — thesis weakened
The euro leg still validates on October and December ECB pricing, but the market has hardened toward a 5 November BoE hike — the single event our invalidator names — and the cross made its cycle high on gilt stress rather than on rate expectations, which is not the mechanism we underwrote.
Long SGD/CHF — invalidator triggered, third review
The SNB held at 0% but raised its inflation path to 2028 on a weaker franc, which is franc-negative near term and precisely how a first Swiss hike gets pulled into our four-quarter invalidator window — the position is through both published objectives with no upside left on the board.

Invalidator watch

One invalidator was defused and three escalated. GBP/JPY closed below its named threshold inside the post-BoJ clock, taking our largest position off the critical list; in exchange, the RBNZ's October repricing moved both AUD/NZD invalidators from Clear to Watch and hardened the November BoE limb that sits across four sterling positions at once. All ten positions remain directionally valid — the risk is now concentrated in sizing on the antipodean block, not in direction.


Next week

Sun Sep 27 Swiss neutrality referendum Affects: SGD/CHF
Tue Sep 29 RBA Monetary Policy Board decision Affects: GBP/AUD, AUD/NZD
Wed Sep 30 Australia Q3 CPI Affects: GBP/AUD, AUD/NZD
Wed Sep 30 US Q2 GDP third estimate, August PCE Affects: GBP/USD, NZD/USD, USD/SGD
Ongoing US–Iran talks on the Strait of Hormuz Affects: GBP/USD, NZD/USD, EUR/GBP

The RBA on Tuesday is the one that matters: at 92–94% priced, delivery is fully discounted and buys us nothing, while a hold would hit Short GBP/AUD and Long AUD/NZD in the same session.
