- Oil's 9-11% collapse on US-Iran de-escalation reshaped the FX week, pulling commodity-linked yields lower and capping CAD/NOK gains against a softer dollar.
- RBNZ held at 2.25% via a 3-3 split vote with a hawkish casting decision, lifting NZD/JPY +2.05% and NZD/USD through 0.5990 — the standout G10 trade of the week.
- DXY closed at 98.94 (-0.25%) near two-week lows after soft PCE revived dovish Fed pricing, but month-end USD demand kept the dollar from breaking down further.
The Week in the Dollar
The dollar index finished the week at 98.94, down 0.25%, the third straight weekly fade and a fresh two-week low. The driver was a Thursday PCE print that landed below expectations on the monthly headline and core reads, even as the annual prints held at 3.8% and 3.3%. That mix — soft enough to keep the December rate-hike probability capped near 46% — pulled front-end yields lower and gave the high-beta bloc room to run.
The second story was crude. Reports of a tentative US-Iran ceasefire extension and possible reopening of the Strait of Hormuz sent WTI down 8.92% to $87.76 and Brent down 10.61% to $91.70. That move would normally weigh on CAD and NOK, but USD/CAD only added 0.12% to 1.3793 and USD/NOK actually fell 0.23% to 9.2288 — the dollar’s own weakness offset the oil drag. Gold added 0.66% to $4,570 as Treasury yields slipped, and copper’s 2.19% gain to $6.394 lent a bid to AUD, which closed +0.53% at 0.7186.
Key Pair Breakdown
NZD/JPY +2.05% to 95.375. The week’s biggest G10 move and entirely an RBNZ story. The bank held the OCR at 2.25% on Wednesday, but a 3-3 committee split forced Governor Breman’s casting vote to keep policy on hold — and her press conference flagged at least two potential 25bp hikes before year-end on a Q2 inflation forecast of 4.2%. Carry-positive Kiwi against a yen still pinned by ultra-low rates is the cleanest trade of the week. The pair is now testing the 95.50 zone last seen in early May.
NZD/USD +1.90% to 0.59902. The same hawkish RBNZ catalyst, amplified by the soft PCE print on the other side. The kiwi broke through 0.5900 for the first time in over a week and closed right at the figure. 0.6000 is the first real resistance into next week — a level that’s capped every rally since mid-April.
USD/SEK -1.16% to 9.2285. The krona’s strength is partly USD weakness, partly a European risk-on tone as oil collapsed and the geopolitical premium drained out of cross-asset volatility. SEK tends to track risk appetite more than its own macro, and a week with soft US data plus de-escalation headlines is exactly the regime it wants.
The rest of G10 was quiet. EUR/USD added 0.33% to 1.1659, GBP/USD 0.18% to 1.3457, and USD/JPY barely moved at 159.26 (+0.19%) — the yen’s safe-haven bid from lower oil was offset by the unchanged yield gap. USD/CHF -0.73% to 0.78075 was the cleanest haven trade as Swiss franc absorbed both the gold bid and the soft-dollar flow. The euro crosses told a similar story: EUR/JPY +0.52%, EUR/CAD +0.48%, EUR/CHF -0.38% — a mild euro bid against everything except the franc.
Week Ahead Setup
NZD/USD at 0.5990 is the chart everyone watches into next week. A clean break of 0.6000 would confirm the RBNZ hawkish-hold trade and open 0.6080. Failure rejects the move and likely sends the pair back to 0.5900 support. NZD/JPY at 95.375 has more runway if the yen stays anchored, but the pair is extended on weekly RSI.
The calendar is heavy. US ISM Manufacturing Monday, JOLTS Tuesday, ADP and ISM Services Wednesday, then nonfarm payrolls Friday — a soft payroll print would extend the dollar fade and put DXY 98.00 in play. ECB minutes mid-week could push EUR/USD toward 1.1700. For oil-sensitive pairs, watch whether the Iran ceasefire holds; a reversal puts the WTI 90 handle back in scope and would lift USD/CAD off 1.3800 support.
Bottom Line
The dollar’s defensive tone heading into NFP week leaves the high-beta commodity bloc — particularly NZD and AUD — with room to extend if US data stays soft and oil stays heavy. The one chart traders are most likely watching: NZD/USD at the 0.6000 figure, where the post-RBNZ rally either confirms or fails.
