  • Dollar index dropped below 99 as DXY fell 0.85%, with gold surging nearly 5% to $4,581 reinforcing the safe-haven bid
  • Swiss franc dominated G10 — USD/CHF plunged 1.65% to 0.797, its sharpest single-session drop in months
  • Scandinavian currencies rallied hard against the dollar, NOK gaining 1.08% and SEK up 0.83%

Overnight Summary

The dollar was hit from all sides overnight, with DXY sliding 0.85% to 98.8 as safe-haven flows poured into the Swiss franc and gold ripped nearly 5% higher to $4,581. The move was broad-based — every G10 currency gained against the greenback — but the franc stood out as the clear winner, with USD/CHF dropping 1.65% to 0.797. Scandinavian currencies were the next-best performers, NOK and SEK both rallying over 0.8% against the dollar. Commodity context was mixed: WTI slipped 0.64% while Brent edged up 0.60%, and copper added 0.40%. The gold move dwarfed everything else in the commodity complex and set the tone for the session.

Key Pair Breakdown

USD/CHF (0.797, -1.65%): The biggest mover of the session by a wide margin. Gold’s $215 surge to $4,581 and the broad dollar dump fed a classic safe-haven rotation into the franc. The pair is now trading below 0.80 — a level that has acted as a floor multiple times this year. A sustained break here opens the door toward 0.790.

GBP/CHF (1.0845, -1.27%): Sterling couldn’t keep pace with the franc’s rally despite GBP/USD posting a 0.43% gain. The cross dropped through 1.09 and is testing levels not seen since early summer. The divergence between franc strength and sterling’s modest dollar gains tells you the CHF bid was the dominant force, not GBP weakness.

USD/NOK (9.314, -1.08%): The krone rallied sharply despite the mixed oil picture. Brent’s modest gain may have helped at the margin, but this move was primarily about dollar selling. The pair is back below 9.35 and approaching the 9.30 handle.

EUR/CHF (0.9306, -0.88%): Even the euro lost ground to the franc, reinforcing that the CHF move was safe-haven driven rather than just anti-dollar. EUR/CHF below 0.935 puts the pair in a range that has historically drawn SNB attention.

EUR/USD (1.1681, +0.85%): The euro rode the dollar weakness higher and is now pressing toward 1.17. The pair has been grinding higher for several sessions, and a clean break above 1.17 would open up the 1.175-1.180 zone.

USD/SEK (9.428, -0.83%): The Swedish krona mirrored the NOK move lower. Both Scandis benefited from the broad dollar rout, with USD/SEK dropping back below 9.45.

USD/JPY (158.11, -0.77%): The yen gained against the dollar but underperformed the franc and the Scandis. EUR/JPY was essentially flat at 184.57, which tells you the yen’s move was entirely a function of dollar weakness rather than independent yen demand. The 158 level is back in play after the pair held above it for most of the week.

AUD/JPY (112.6, -0.58%): The Aussie’s modest 0.24% gain against the dollar wasn’t enough to offset yen strength, pushing this cross lower. Copper’s 0.40% gain gave AUD some support but not enough to outrun the yen bid.

EUR/AUD (1.638, +0.55%): The euro outperformed the Aussie on the session, widening this cross. AUD/USD’s relatively muted 0.24% gain against a dollar that was down nearly 1% everywhere else highlights that the Aussie was a laggard in the G10 rally.

USD/CAD (1.380, -0.48%): The loonie gained against the dollar but underperformed peers. With WTI actually lower on the session, CAD lacked the commodity tailwind that NOK got from Brent’s modest bid.

Asian Session Setup

Sydney and Tokyo open into a market where the dollar is on its back foot and gold is screaming higher — a combination that typically keeps USD offers in play through the Asian morning. USD/JPY at 158.11 is the pair to watch: the BoJ intervention zone starts getting closer below 155, but the pair would need another session of this magnitude to get there. For now, the 157.50-158.50 range is the battleground.

AUD/USD at 0.7125 was a relative underperformer overnight despite copper’s gain. If the risk-on tone carries into the ASX open, a push toward 0.715 is in play. NZD/USD at 0.593 is also worth watching — the pair broke above 0.59 and a follow-through above 0.595 would confirm the move.

The DXY break below 99 is a headwind for anyone positioned long dollars into Asia. If gold holds above $4,550, expect the franc and yen bids to persist through the Tokyo session.

Bottom Line

This was a decisive risk-off-meets-dollar-dump session: gold surged, the franc led G10, and the dollar lost ground against everything. The pair most likely to draw attention into tomorrow’s European open is USD/CHF below 0.80 — a level break that, if it holds, could accelerate the move toward 0.790.
