USD Index Above 101.00 on Inflation & Iran Tensions Lift Dollar

London is opening — here is the forex sentiment setup heading into the European session. 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) surges to 72/100 bullish as the greenback breaks above 101.00 on inflation resilience and rising Treasury yields.

This briefing explains why the US Dollar rallied Tuesday, which currency pairs face the steepest headwinds, and what data could extend or derail the move.

What Happened

The US Dollar Index punched above 101.00 on Tuesday, propelled by twin tailwinds: a resilient inflation backdrop and climbing Treasury yields that have reinforced the case for elevated US interest rates. Safe-haven demand also lifted the greenback as geopolitical tensions between the US and Iran escalated, with Iran's IRGC claiming strikes on US military targets in Bahrain and Kuwait, while US CENTCOM responded with strikes on Iran's command centres and air defence systems. This risk-aversion impulse typically benefits the dollar as traders rotate into the world's most liquid reserve asset.

Despite headline equity market jitters, USD strength persisted because the inflation narrative outweighed recession fears. The combination of sticky price pressures and widening rate differentials—particularly versus the yen and the euro—kept buyers engaged in dollar pairs. Treasury yields climbed in anticipation that the Federal Reserve will maintain a higher-for-longer policy stance, even as some Fed repricing has begun to take root. This confluence of structural support—inflation expectations, yield advantage, and geopolitical risk-off—anchored the USD bid throughout the European session.

Today's news timeline

Market Reaction

The broader forex market articulated a clear risk hierarchy on Tuesday, with the Canadian Dollar suffering the sharpest relative setback at 38/100 bearish—a 34-point sentiment gap separating it from the bullish greenback. USD/CAD climbed as Trump's tariff expansion beyond USMCA protections buttressed dollar demand while simultaneously undermining loonie support; Canadian inflation cooled in June with gasoline prices pulling headline CPI below expectations, eroding Bank of Canada hawkishness at a critical moment.

Elsewhere, the New Zealand Dollar held resilience at 68/100 bullish, buoyed by hotter-than-expected CPI at 4.1% and confirmation that the RBNZ's own sectoral factor inflation model remained anchored at 2.7% year-on-year—signalling rate hike conviction. The Australian Dollar edged higher at 62/100 as AUD/JPY gained traction above 113.50, though it faced persistent USD headwinds in the USD/AUD pair. The Euro and Swiss Franc, both sheltering well below 50/100, ceded ground as safe-haven demand flowed into dollar assets rather than traditional franc strength, while sterling clung to neutral territory at 55/100, held aloft only by modest fiscal support from the UK government's VAT cut announcement.

What's Driving the Move

Three key threads run through the bullish US Dollar story:

  1. USD Index broke above 101.00 as headline and core inflation measures sustained central bank rate-hike expectations, supported by climbing US Treasury yields that widened the dollar's yield advantage over major peers.
  2. Safe-haven capital rotated into the US Dollar rather than traditional safe-havens; Iran's IRGC strikes on US military targets and US CENTCOM retaliation intensified geopolitical risk-off, with investors choosing dollar liquidity over franc or yen strength.
  3. Canadian Dollar weakness in USD/CAD accelerated as Trump's tariff escalation beyond USMCA terms undermined loonie demand simultaneously with softer domestic inflation prints that dimmed BoC rate-hike signals for the remainder of 2026.

What to Watch Next

📈 Bull case for the move
A break and close above USD/CAD 1.4100—the key confluence hurdle cited in intraday technicals—would signal acceptance of higher levels and reinforce tariff-driven dollar strength. If US inflation data over the next 48 hours prints hotter than expected or Fed speakers reiterate higher-for-longer messaging, the greenback could extend its run toward 101.50 on the index, pulling USD/JPY and EUR/USD lower in tandem.
📉 Risk to the view
A de-escalation in US-Iran tensions or a dovish surprise from Fed speakers suggesting rate cuts are imminent would flip the narrative from safe-haven-supported strength to yield-driven weakness. If gold breaks decisively above $4,050—currently testing that level as subdued USD demand resurfaces—it would signal a shift toward risk-on sentiment that could unwind the dollar's geopolitical premium and trigger profit-taking in long USD positions.

Watch the early Asia session for any fresh updates on Middle East developments and Japanese yen positioning, which could influence USD/JPY momentum and set the tone for London's Wednesday open.
