The week's defining event landed Monday: Andy Burnham became the UK's seventh prime minister in a decade, and benchmark British borrowing costs edged higher on Monday, though sterling gained slightly, as investors awaited Burnham's first decisions including who he will choose as his finance minister — a clarified political backdrop that keeps our GBP/USD short (rank 8) firmly offside. Crucially, markets will be "relieved" that Burnham is set to select home secretary Shabana Mahmood as chancellor, rather than the more left-leaning Ed Miliband, and the fiscal reassurance carried sterling to fresh highs — sterling hit its strongest level in a year as speculation Burnham will name a markets-friendly chancellor accelerated a shift away from bearish positions, with the Bloomberg British Pound Index rising as much as 1% Wednesday to its highest since July 2025. Meanwhile, escalating attacks between the US and Iran heightened Middle East tensions, driving crude oil prices higher and triggering safe-haven demand for the US dollar — the same energy-inflation channel that continues to underwrite the BoE-hike repricing punishing our cable short. And Tuesday brings the New Zealand June-quarter CPI on 21 July, with forecasts of a 1.5% quarterly rise lifting annual inflation to around 4.1%, the highest in two years — directly relevant to our NZD/JPY short (rank 3).
How our views are tracking
|
Short CAD/JPY — thesis weakened The yen resumed a broad slide while CAD firmed post-BoC, de-synchronising both legs of the double-short and driving the position sharply offside on our largest yen-cross bet. |
|
Short NZD/JPY — thesis weakened The post-RBNZ kiwi bid extended into a full breakout as the yen weakened, overrunning both legs — and Tuesday's hot NZ CPI risks compounding the pain. |
|
Short EUR/SGD — thesis strengthened SGD held firm while the euro faded its brief soft-CPI dollar bounce, leaving this the cleanest directional expression in the book. |
Invalidator watch
No level-based invalidator has triggered — the 1.3000 stop on our GBP/USD short sits over 400 pips away and the yen crosses carry no hard price stop — but two positions (GBP/USD and NZD/JPY) are now failing on thesis rather than level, with sterling's move to one-year highs and the RBNZ-hike aftershock both structural misses. All positions remain technically valid, but the yen-cross bucket has flipped from the book's strength to its single largest source of loss, and Tuesday's NZ CPI plus the July 31 BoJ decision are the near-term arbiters of whether it recovers.
Next week
| Tue Jul 21 | New Zealand Q2 CPI | Affects: NZD/JPY |
| Wed Jul 22 | UK CPI (June) | Affects: GBP/USD |
| Thu Jul 23 | ECB Governing Council | Affects: EUR/USD, EUR/SGD |
| Wed Jul 29 | FOMC decision (Warsh) | Affects: EUR/USD, USD/JPY |
| Fri Jul 31 | BoJ decision + Outlook | Affects: all JPY crosses |
The July 31 BoJ decision is the fulcrum for the entire book. With board member Tamura arguing the policy rate should gradually move toward a neutral level of around 2% via 0.25-point hikes at intervals of a few months, a hawkish refresh could reverse this week's yen-cross damage in a single session — but if the decision fails to shift the carry math, four short positions drift further offside.
