Overnight Summary

The dollar index sat dead flat at 101.5 overnight, masking a violent split beneath the surface — crude oil collapsed 8-9% while copper rallied over 1%, creating a clear winner and loser among commodity currencies. The Aussie dollar was the session’s standout, gaining against every G10 peer as copper’s 1.2% rise and broader metals strength offset the oil rout. The Norwegian krone took the other side of that trade, sliding 0.42% against the greenback as WTI cratered to $81.91 and Brent fell to $87.68. Gold edged up 0.27% to $4,079 but wasn’t enough to spark meaningful safe-haven flows into JPY or CHF — both were near-flat against the dollar.

Key Pair Breakdown

GBP/AUD — 1.9011 (▼ 0.49%)

The session’s largest G10 move. Sterling gave back half a percent against the Aussie as AUD rode the copper bid and GBP/USD slipped 0.14%. The cross is pressing toward the 1.90 handle — a clean break below would open the door toward 1.89 territory. The move reflects pure AUD outperformance rather than sterling weakness; cable’s decline was modest by comparison.

EUR/AUD — 1.6258 (▼ 0.43%)

Same AUD-strength dynamic. EUR/USD barely moved (+0.07%), so the cross drop is almost entirely AUD-driven. The pair has pushed below 1.63 and is testing the lower end of its recent range. Copper strength and the broader risk-on tone in metals markets are the tailwinds here. Any follow-through in Asian base metals trading could extend this move.

USD/NOK — 9.6527 (▲ 0.42%)

The krone was the session’s weakest G10 currency, and the driver is obvious — WTI’s 8.3% crash and Brent’s 9.4% drop. Norway’s petroleum-dependent economy makes the krone one of the most oil-sensitive currencies in the G10 basket. USD/NOK pushed above 9.65, and if oil stays under pressure, the 9.70-9.75 zone is the next area of interest. Worth noting that EUR/NOK (not listed but implied from EUR/USD and USD/NOK) would have rallied about 0.49% — a sizeable one-session move for that cross.

Asian Session Setup

The AUD is the pair to watch at the Sydney open. AUD/USD at 0.6993 is knocking on 0.70 — a psychologically loaded level that has acted as resistance multiple times this year. Copper’s 1.2% overnight gain gives the Aussie momentum, but whether the 0.70 break sticks depends on whether Asian metals markets confirm or fade the move. AUD/JPY at 114.37 is another focus — the cross combines AUD strength with mild yen softness.

USD/JPY at 163.69 drifted lower by just 8 pips overnight. The pair remains elevated and the flat DXY gives Tokyo little directional cue. With oil’s crash not translating into broad risk-off (gold only +0.27%, equities implied steady), there’s no catalyst for a sharp yen bid at the open. CAD/JPY at 115.89 fell 0.36% overnight — the oil-linked CAD weakness against the mild yen bid made this the quiet mover worth monitoring if crude stays offered.

Bottom Line

The overnight session was about commodity divergence, not dollar direction — oil crashed, copper rallied, and the FX market priced it cleanly through NOK weakness and AUD strength. The pair most likely on traders’ screens at the Asian open is AUD/USD, sitting one tick below 0.70 with metals momentum at its back.
