Strait of Hormuz Strikes Reset Dollar Risk Ahead of PCE

The tentative peace narrative in the Middle East collapsed at the European cash open as fresh US airstrikes targeted an Iranian drone operation in Bandar Abbas, a port city near the Strait of Hormuz. The strikes, described by the Pentagon as defensive, reset risk appetite just hours before the April PCE price index release – a data point that will influence whether the dollar extends its recent bid or loses altitude.

Strait of Hormuz: Ceasefire Framework Under Strain

US Defensive Strikes and Iranian Drone Interception

US forces carried out airstrikes on an Iranian drone operation in Bandar Abbas. Separately, the US military intercepted four Iranian attack drones aimed at a commercial vessel. The Pentagon stated that the ceasefire framework remains intact. Chief market analyst Aaron Hill of FP Markets argued that the distinction between defensive action and escalation is becoming academic when both sides exchange blows with regularity.

Diplomatic Fog

Iranian state television circulated reports that an interim framework to normalise maritime traffic through the Strait was close to completion, with a timeline of roughly one month. The White House dismissed that characterisation. President Trump later told a cabinet meeting that no single nation would govern access to international waters. Hill noted that the longer-dated oil futures curve has remained stubbornly elevated through recent volatility, signalling that the market’s base case is prolonged disruption rather than imminent resolution.

Oil: Brent Rebound and the Futures Curve Signal

Brent crude recovered from Wednesday’s downside move, bouncing back toward the mid-$90s. That decline had been triggered by a brief surge in peace-deal optimism. The backwardation in the futures curve has held steady, a structural signal that supply constraints are expected to persist.

Crude Benchmark	Wednesday Close	Recent Move
Brent (front month)	~$92	Recovery to mid-$90s
WTI (front month)	~$88	Following Brent higher

The inflationary transmission from elevated energy prices is the dominant macro theme heading into the second half of 2026, according to Hill. That channel flows directly into the Fed’s preferred inflation gauge, the PCE deflator.

Treasury Yields and USD/JPY: Geopolitical Premium Meets PCE

10-Year and 30-Year Above Key Levels

The 10-year US Treasury yield climbed 4 basis points to just above 4.5%. The 30-year remained anchored above the psychologically significant 5% level, where it has traded for most of May. Rising term premiums, driven by both inflation expectations and geopolitical risk, are compressing real yields and pushing nominal rates higher.

USD/JPY Pressing ¥160 Intervention Zone

The dollar nudged higher against a basket of peers. The move was most pronounced against the yen, with USD/JPY pressing toward ¥160. That level has historically triggered formal intervention by Japan’s Ministry of Finance (MoF). Traders will watch the PCE print as the proximate catalyst for a breach. Japan’s macro backdrop argues for caution: the Bank of Japan remains on a normalisation path, timing secondary to economic readiness. For a deeper look at the policy calculus, see Why BoJ Rate Hike Timing Is Secondary to Economy's Readiness.

Practical rule: A core PCE print that exceeds 3.4% closes the window for dovish repricing and accelerates short-end tightening expectations. That scenario favours the dollar outright, especially against low-yielding currencies like the yen.

PCE Inflation: The Data That Could Break the Dollar

Consensus and Scenarios

Consensus for the April PCE price index, due at 12:30 GMT, sits at 3.8% year-over-year for the headline measure – a three-year high. The core reading is anticipated at 3.3% YY, comfortably above the Fed’s 2% target.

Indicator	Consensus	Bullish USD Scenario	Bearish USD Scenario
Headline PCE YY	3.8%	Above 3.8%	Below 3.6%
Core PCE YY	3.3%	3.4% or higher	3.1% or lower

Hill argued that a core print of 3.4% or above would cause the front end of the Treasury curve to reprice hawkishly and push USD/JPY through the ¥160 intervention threshold. A softer-than-expected core would provide some breathing room for the Fed. Meaningful dollar weakness is unlikely given the geopolitical premium baked into energy prices.

Fed Hawkish Tone

Federal Reserve officials have sharpened their language. Governor Lisa Cook stated on Wednesday that inflation is heading in the wrong direction and that she stands ready to raise rates should the deterioration persist. Vice Chair Philip Jefferson, speaking in Tokyo on Thursday, acknowledged the labour market’s resilience while emphasising that the focus must remain squarely on returning inflation to 2%. The combined messaging reinforces the risk that the Fed will not cut rates this year – and may need to hike if PCE data surprises to the upside.

Risk to watch: A headline PCE above 4.0% would cause the market to price a Fed hike at the June or July FOMC meeting, accelerating risk-off across equities and EM currencies.

Risk Appetite: Equities and Asia-Pacific Unwind

In the S&P 500, 236 stocks rallied while 263 ended in the red. Sector performance was roughly even. Asia-Pacific equity markets unwound sharply overnight, sending key regional indices south and snapping a run higher underpinned by AI-driven earnings momentum. The unwind in Asia is the most immediate transmission from the Hormuz strikes. Higher oil prices are a direct headwind for net importers like Japan, Korea, and India. If Brent sustains above the mid-$90s, the equity rotation out of cyclical and consumer-discretionary names could accelerate.

PCE Scenarios and MoF Intervention Risk

For the rest of the session, all eyes are on the PCE release. The four scenarios to track:

Core PCE at or above 3.4%: USD/JPY breaks ¥160, Treasury yields rise, gold falls.

Core PCE between 3.2% and 3.3%: Status quo – dollar holds firm, yen intervention remains a risk.

Core PCE below 3.1%: Short-covering in yen and gold, geopolitical premium limits dollar downside.

Headline PCE above 4.0%: Market prices a Fed hike at the June or July FOMC meeting; risk-off intensifies.

The dollar is priced for a hot print. The geopolitical overlay makes the reaction function asymmetric. A miss to the downside may not be enough to unwind the energy-driven risk premium. A beat could ignite the next leg higher in the dollar and push USD/JPY into uncharted intervention territory.

Traders should size positions expecting elevated volatility into the US afternoon and potential Japanese intervention within 24 hours of a ¥160 break.
