Tokyo and Washington confirmed joint yen-buying intervention on Friday, and the yen added another 1% on Monday to 156.01 after a more than 3% surge over two sessions, with Bank of Japan data suggesting Japan may have bought as much as $58.97 billion on Thursday — that official bid is the spine of every yen-cross short in this cycle. Swiss July CPI slowed to 0.4% year-on-year with core steady at 0.3%, leaving Q3 tracking below the SNB's own 0.7% forecast — the one condition capable of restoring Swiss policy optionality just moved further out of reach, which is the cleanest possible read-through for our three franc longs. September Fed hike odds have receded to roughly 60% from 75% a week earlier as easing oil prices repriced the front end, putting Friday's payrolls squarely in the path of the dollar leg.
A central bank that has pre-committed to a zero policy rate for three years has stopped running a currency and started running a funding facility — and the market is only part-way through monetising it.
Three themes driving G10 FX
- The franc is the funding leg now — Eight of the thirteen best-financed directional trades in our set are franc shorts, and this week's CPI removed the only credible route back to Swiss optionality inside the horizon.
- The yen trade got an official sponsor — A 185,047-contract speculative short now sits against a Ministry of Finance operating with explicit US Treasury participation, which converts a stale positioning statistic into a live, dated catalyst.
- Level versus change is the whole game — Forwards already pay you for the size of a rate gap but nothing for its direction of travel, which is why several Antipodean-versus-dollar pairs flip sign between our tactical and strategic horizons.
Our top 3 trades
|
Long SGD/CHF One central bank manufactures appreciation through a steepening band slope while the other has pre-committed to nothing until 2028. Carry: +97bp — runs with the position, unusual for a franc short |
|
Long CAD/CHF Neither bank meets inside the window, so a 225bp gap is a fixed parameter while spot sits well below relative-REER parity. Carry: +225bp — paid to hold, and the forward gives the differential away |
|
Long AUD/CHF The widest differential in the set, 435bp, harvested against a cross realising under 6% volatility — and the only AUD axis that does not compress. Carry: +435bp — the best-financed position in the book |
On our radar
| Aug 7 | US payrolls and Canada Labour Force Survey, same morning | Affects: CAD/CHF, AUD/CHF |
| Aug 11 | RBA decision plus Statement on Monetary Policy | Affects: AUD/CHF |
| Aug 19 | Section 338 tariffs effective: 50% on ~$20bn of Canadian goods | Affects: CAD/CHF |
| Aug 23 | Singapore July CPI and MAS core | Affects: SGD/CHF |
The 19 August tariff date carries the highest asymmetry: the proclamations were signed on 20 July with no sunset and no carve-out, the pair has barely moved on the news, and the market is effectively pricing deferral as a certainty — which is why we would rather establish the Canadian leg after the date than into it.
Carry snapshot
Carry is working, but the working is concentrated: the best-scoring positions and the best-financed positions overlap almost exclusively in the franc complex, while the highest-payoff yen shorts charge you 125bp to 335bp a year to wait. That split dictates expression — franc longs belong in open-ended forwards, yen shorts belong in a defined holding period or a convexity structure.
