Now I have the full macro picture. Let me write the post.

The dominant story: **joint US-Japan yen intervention** (first coordinated since 2011) crushed USD/JPY from 163 to ~157. OPEC+ added 188k bpd (fifth straight hike) sending oil down ~9%. Gold surged nearly 9% on safe-haven flows. BOJ held at 1% on July 31 but warned inflation could overshoot 2%.

Here’s the post:

The Week in the Dollar

The dollar index drifted lower to 99.6, shedding just 0.2% on the week — but that headline number hides the real action. The week belonged to the yen, where a rare joint US-Japan intervention yanked USD/JPY from above 163 down to 157.74, a 1.5% weekly drop and the sharpest G10 move by a wide margin. Tokyo and Washington confirmed their first coordinated currency intervention since 2011, with the BOJ reportedly deploying over ¥13 trillion across two sessions to halt the yen’s slide to 40-year lows.

Commodities told two very different stories. Gold ripped 8.7% higher to $4,401, its best week since January, as safe-haven demand surged alongside falling rate-hike expectations. Oil went the other direction — WTI collapsed 9.0% to $77.08 after OPEC+ approved a fifth consecutive output increase of 188,000 bpd into a market where global demand is already cracking. Copper climbed 2.3%, giving the Aussie a modest tailwind.

Key Pair Breakdown

USD/JPY — 157.74, down 1.5%. The week’s clear outlier. The pair was trading above 163 before Tokyo and Washington pulled the trigger on coordinated intervention late in the prior week, and the follow-through held into this one. The BOJ’s July 31 hold at 1% came with an upgraded inflation warning — core CPI could run “clearly above” 2% in H2 — keeping a September hike firmly on the table. The combination of intervention overhang plus hawkish guidance locked in the weekly loss. Next test: whether 156 holds as the intervention floor or gets probed on any US data strength.

GBP/JPY — 212.88, down 1.3%. Sterling held its own against the dollar (GBP/USD flat at 1.3493), so the cross decline was pure yen strength. The pair shed 270 pips on the week. Traders are watching the 210 handle as the next support zone if intervention momentum extends.

EUR/JPY — 182.38, down 1.2%. Same story — EUR/USD was quiet at 1.1562 (+0.3%), meaning the cross was dragged lower entirely by yen appreciation. The ECB remains on hold with eurozone growth data mixed, so the euro side offered no offset to the JPY bid.

NZD/JPY — 92.99, down 1.2%. The kiwi gained modestly against the dollar (+0.3%), but the yen’s intervention-fuelled rally pulled the cross lower. NZD/JPY is now testing the 93 level, the lowest since mid-July.

Week Ahead Setup

The intervention overhang keeps USD/JPY front and centre. Tokyo signalled it “will not hesitate” to act again, so any drift back toward 160 becomes a live intervention risk. The 156–158 range is the new battleground — a clean break below 156 would suggest the intervention is gaining traction beyond the initial shock.

Oil’s 9% drop puts CAD and NOK in focus. USD/CAD at 1.3936 is already drifting lower on broader dollar softness, but another week of crude weakness could flip that. NOK was flat (USD/NOK -0.06%) despite the oil rout — that divergence either snaps back or reflects NOK-specific positioning.

Gold’s 8.7% surge reinforces the safe-haven bid that’s supporting both JPY and CHF. If risk appetite deteriorates further, AUD/JPY (111.52) and CAD/JPY (113.18) — both already down nearly 1% — have room to extend.

On the calendar, US CPI and any Fed commentary will be the main catalysts. A soft print would validate the rate-cut pricing that’s helping gold and pressuring the dollar.

Bottom Line

This was an intervention week — Tokyo and Washington rewrote the yen’s trajectory, and the rest of G10 mostly watched. USD/JPY at 157.74 is the pair every desk is watching heading into next week, because what happens when the intervention dust settles will set the tone for August.
