Citable research brief

Core conclusion · Tlines extraction

The G7 foreign exchange market is being driven by three converging forces: a yen surge to a seven-month high on expected BOJ tightening, Brent crude above $100 per barrel following US-Iran military escalation, and a synchronized global tightening cycle with the ECB having hiked on 10 September, the BOJ widely expected to move on 18 September, and Fed rate-rise odds at 58–70% for the 15–16 September meeting. The dollar index sits near two-week lows at 98.80, with USD/JPY falling from 160.53 to 153.54 over three months, while the Swiss franc is the only G7 currency to have weakened against the dollar, down 1.29%, as it replaces the yen as the carry-trade funding currency. The coming week carries a rare triple central bank event risk—Fed, BoE, and BOJ decisions in three consecutive days—with EUR/USD weekly implied volatility jumping from 4.8 to 6.5.

Key arguments

Middle East escalation—US neutralising ten Iranian oil tankers, IRGC retaliating near the Strait of Hormuz, and Houthi attacks on Saudi oil infrastructure—has pushed Brent above $100–105/bbl and gold above $4,400/oz, reigniting global inflation concerns.
The yen is the standout G7 performer, appreciating 3.9–4.4% over three months, supported by BOJ hike expectations (97% of economists see 1.25% on 18 September), coordinated US-Japan intervention (15.4 trillion yen of yen-buying in July–August), and an unwinding carry trade.
The ECB raised rates 25bp to 2.50% on 10 September and markets price two further hikes by end-2026 and a 3.1% rate by end-2027; Lagarde warned Middle East conflict will keep inflation above target for an extended period.
The BoE is expected to hold at 3.75% for the sixth consecutive time, but sterling's recovery looks fragile as the UK lags G7 peers in tightening, 30-year gilt yields hit 5.8168% (highest since 1998), and mortgage rates rose ~75bp since hostilities began.
The Swiss franc is the weakest G7 currency this quarter (USD/CHF from 0.7996 to 0.8099), used as an alternative carry-trade funding currency with the SNB policy rate at zero and a real policy rate near -1%.
The Canadian dollar faces a tug-of-war between oil above $100 supporting the commodity currency and US tariffs now affecting US$20bn (5%) of Canadian exports.
The week of 11–18 September is dominated by triple event risk—Fed (16th), BoE (17th), and BOJ (18th)—with the US August CPI on 11 September the key data point that could determine the FOMC outcome.

Key numbers

Brent crude price: above $100–105 per barrel
Spot gold price: above $4,400 per ounce
US Dollar Index (DXY): 98.44–99.00, near two-week lows at 98.80
USD/JPY (three-month move): from 160.53 to 153.54 (-4.4% USD, +4.4% JPY)
EUR/USD (three-month move): from 1.1535 to 1.1632 (+0.84%)
GBP/USD (three-month move): from 1.3366 to 1.3542 (+1.32%)
USD/CHF (three-month move): from 0.7996 to 0.8099 (+1.29% USD, -1.29% CHF)
USD/CAD (three-month move): from 1.3939 to 1.3802 (-0.98% USD, +0.98% CAD)

Main risks

A core CPI upside surprise on 11 September, combined with oil above $100, could sharply raise the probability of a Fed rate hike and trigger broad dollar strength.
The FOMC outcome is highly uncertain: a 25bp hike with a hawkish tone would lift USD and push USD/JPY to 156–157, while a surprise hold would send EUR/USD to 1.1800–1.1850 and USD/JPY below 152.
Any shift in the BoE vote from 6-3 to 5-4 would be a very aggressive signal for the pound, especially with UK gas prices already exceeding the BoE's adverse scenario (202 vs. 197 pence/therm).
BOJ Governor Ueda's press conference could move the yen sharply if he signals faster or larger-than-25bp tightening; Masu warned the BOJ may be forced to raise rates rapidly if inflation accelerates.
The Swiss franc's role as a carry-trade funding currency could amplify volatility if risk sentiment shifts or SNB policy expectations change.
Escalation in the Middle East conflict remains the dominant energy-price risk, with the potential to keep inflation above central bank targets for an extended period.
