USD Rallies to 98.84 on Iran Sanctions, Canadian Tariff Shock Crushes Loonie

Asia session is opening, here is the overnight forex sentiment picture as Tokyo, Singapore and Sydney desks come online. US Dollar (USD) leads forex sentiment today with a strong bullish reading. Here is what drove the move and what to watch next.

US Dollar, USD, 72/100, Bullish: Safe-haven demand and escalating Iran sanctions push the greenback to fresh resilience despite Treasury bond buyback headwinds.

Learn why the US Dollar index bounced to 98.84 on geopolitical risk, how Canadian tariff fallout crushed the Loonie, and which technical levels matter most for USD/CAD traders over the next 24 hours.

What Happened

The US Dollar climbed on Tuesday as safe-haven flows accelerated following heavier Iran sanctions, offsetting lingering concerns over Treasury yield suppression. The dollar index recovered to 98.84 after testing session lows, signalling that geopolitical risk appetite remains a primary driver. ForexLive noted that Treasury Secretary Bessent softened Iran sanctions rhetoric as the yield fix unravels, yet the damage to risk sentiment persisted, keeping capital flows tilted toward the greenback.

Central to USD momentum was the broadening risk-off environment triggered by escalating trade tensions. Canada walked away from trade negotiations as US tariffs took effect, prompting retaliatory measures that sent the Canadian Dollar reeling. The sanctuary appeal of the US currency was further reinforced by a data-heavy Tuesday schedule ahead, encouraging traders to de-risk positions and seek shelter in the world's reserve currency before potential volatility spikes.

Today's news timeline

Market Reaction

The FX session displayed stark divergence across majors, with the widest sentiment gap emerging between the bullish US Dollar at 72/100 and the bearish Canadian Dollar at just 32/100. USD/CAD reflects this chasm directly: the pair surged as the Loonie absorbed twin shocks from tariff implementation and failed trade talks, creating an asymmetric technical setup favoring dollar strength. Meanwhile, commodity-linked currencies including the Australian Dollar and New Zealand Dollar sold off in sympathy, as Iran sanctions clouded the risk appetite needed to sustain demand for growth-sensitive assets.

The Japanese Yen, rated 68/100 bullish, added complexity to the session. Despite official intervention support and ex-board member comments flagging 80% odds of BOJ hikes next month and January, the yen underperformed the dollar as safe-haven flows favoured the benchmark currency. EUR/USD capped resistance at 1.1700 with overbought technicals, while EUR/JPY bulls stalled at 187 on intervention fears, underscoring broad dollar strength across the major crosses.

What's Driving the Move

Three key threads run through the bullish US Dollar story:

  1. Escalating Iran sanctions and geopolitical risk triggered by Bessent's softer tone created unexpected safe-haven demand that propelled the dollar index back above 98.80, reversing earlier session weakness.
  2. Canada's breakdown in trade negotiations and implementation of US tariffs decimated the Loonie, amplifying USD/CAD's bullish momentum as tariff uncertainty pressures growth-sensitive currencies.
  3. BOJ intervention history and rising hike expectations for September and January failed to support yen upside, allowing the dollar to establish itself as the primary safe-haven beneficiary despite technical overbought conditions in some USD pairs.

What to Watch Next

📈 Bull case for the move
A confirmed break above USD/CAD's 1.3850 level combined with softer-than-expected Canadian employment data would extend the pair's rally and validate tariff-driven weakness in the Loonie. Additional risk-off headlines or central bank dovish pivots from G10 peers would cement USD safe-haven status heading into Wednesday's data releases.
📉 Risk to the view
If Treasury buyback concerns resurface and Treasury yields fall sharply, the greenback's safe-haven appeal could evaporate as investors rotate back into growth assets and higher-yielding currencies. A surprise reversal in Iran sanctions policy or rapid de-escalation in US-Canada trade tensions would snap the current risk-off narrative and force a retracement in USD/CAD toward 1.3700.

Watch for the London open at 06:13 UTC and US session continuation at 12:13 UTC, where fresh US data and central bank commentary may test whether 98.84 resistance holds or yields to continued dollar momentum.
