Market Snapshot

Top Movers

Winners & Losers (past 24 hours):

• USDBRL (-0.08% daily, -0.93% weekly): Brazilian real continued to firm, with USD/BRL at 5.0126. Risk-on sentiment tied to tentative Hormuz Strait deal progress, alongside Brazil's strong commodity export backdrop, supported real outperformance this week.
• USDZAR (+0.41%): South African rand weakened modestly (USD/ZAR at 16.353), with weekly ZAR still up +2.03% — tracking the broader EM rally on softer-dollar mood.
• NZDUSD (-0.45%): The New Zealand dollar was the biggest G10 decliner in the session, dropping to 0.5845. The pair's underperformance reflects lingering concerns over domestic growth slowdown; NZD/USD is also down -1.08% on the month.
• USDTRY (+0.52%): Turkish lira weakened, with USD/TRY rising to 45.905. The lira is down -17.83% year-over-year, continuing its persistent structural slide even as the CBRT has kept rates elevated.
• USDUAH (-0.15%): Ukrainian hryvnia nudged firmer against the greenback amid ongoing geopolitical monitoring.

What Moved the Tape

• 🇮🇷 US-Iran Hormuz firefight dominated price action: EUR/USD dropped to ~1.1622 Tuesday — down ~0.15% during North American hours — as the US and Iran exchanged fire near the Strait of Hormuz, temporarily boosting safe-haven dollar demand. Losses were partially reversed as diplomatic optimism returned, with reports suggesting continued negotiations. The DXY held near 99.00 as the two competing narratives (war risk vs. deal hope) created choppy bidirectional flows.

• 🌐 Middle East deal hopes lifted risk appetite earlier this week: At the start of the European session on Monday, EUR/USD traded near 1.1645, supported by optimism around a potential deal to reopen the Strait of Hormuz. Risk currencies including AUD/USD (+0.80% weekly) and GBP/USD (+0.64% weekly) benefited from the more constructive mood.

• 📊 Dollar technical recovery under scrutiny: Reuters' market technicals column noted the dollar "has been cautiously proceeding with a recovery after losing all of its initial Iran-war gains by early May" and is now "drawing close to levels that would lead technical analysts to expect further gains." The DXY's trajectory near 99 is being watched closely for breakout signals.

• 🔄 Geopolitical risks the primary near-term driver: ActionForex noted in its overnight commentary that markets are "closely monitoring reports suggesting a possible prolongation of the negotiation process and an increased US presence" near the Strait of Hormuz, keeping the dollar supported on dips even as longer-term structural dollar weakness narratives remain intact.

Central Bank Watch

• Federal Reserve (USD): Fed rate-cut expectations have been pared back following stronger-than-expected US inflation data in recent weeks. FX Empire analysis noted the "Dollar strengthens as rate-cut hopes fade," with DXY eyeing a channel breakout toward $99.48–$99.66. The market is now watching upcoming US economic data closely to reprice the rate path.

• EUR/USD central bank divergence: The forex.com "Currency Pair of the Week" analysis for May 26 noted the "near-term EUR/USD forecast remains tilted to the downside," reflecting the current ECB vs. Fed policy divergence backdrop where markets still anticipate a more aggressive easing path from the ECB than from the Fed. EUR/USD has lost -0.84% YTD.

• BOJ (JPY): USD/JPY held near 159.18, up +0.17% on the session and up +10.29% year-over-year, reflecting the persistent interest rate differential between the US and Japan. ActionForex's technical outlook noted near-term neutral bias in USD/JPY, with "strong resistance expected" near the 160.71 high area. A break below 157.30 would shift the bias lower.

Emerging Markets & Asia FX

• USD/CNY (6.786, +0.03% daily): The Chinese yuan was little changed on the session but is -2.73% YTD and -5.63% year-over-year, reflecting ongoing PBOC management within a gradual appreciation bias against the dollar. The yuan has gained against the greenback on a weekly basis (-0.45% in USD/CNY terms), consistent with the broader soft-dollar theme.

• USD/KRW (1503.79, -0.57%): The South Korean won was among the better Asian performers on the session, with USD/KRW declining to 1503.79. The won remains +9.31% weaker year-over-year but is firming in the near term alongside broader EM risk-on flows.

• USD/BRL (5.0126, -0.08%): The Brazilian real continues to outperform broadly, with USD/BRL down -9.14% YTD and -11.18% year-over-year — making BRL one of the standout EM performers of 2026 so far. Supportive commodity prices and Brazil's fiscal progress underpin the move.

• USD/MXN (17.292, +0.07%): The Mexican peso is little changed on the session but remains a strong YTD outperformer (-4.03% in USD/MXN terms, meaning peso gains), alongside continued US-Mexico trade linkages and relatively high real yields.

• USD/ZAR (16.353, +0.41%): The South African rand weakened slightly on the session but is still up -2.03% on a weekly basis, tracking broader EM sentiment. Commodity prices and global risk appetite remain the key drivers for ZAR.

Strategist Takes

• Reuters technical team noted that the dollar's recovery rally from its Iran-war lows in early May is now approaching technically significant resistance. "The dollar has been cautiously proceeding with a recovery after losing all of its initial Iran-war gains by early May, and it is now drawing close to levels that would lead technical analysts to expect further gains." The implication is that a clean breakout above these levels could trigger further short-covering in the dollar — but a failure would reinforce the longer-term bearish structural story.

• Dan Tobon, Head of G10 FX Strategy at Citi (from a Reuters piece): "We are dollar bulls in a world of dollar bears right now." Tobon sees the dollar strengthening "up to at least the third quarter of this year, mostly against the euro, Canadian dollar and sterling, even if it is weighed down by factors such as the hedging of dollar exposures by foreign investors and the threat to Fed independence." This contra-consensus call deserves monitoring as the Hormuz geopolitical premium fades and data focus returns.

What to Watch Next

1. US Consumer Confidence / Core PCE data (this week, sensitive pair: DXY, EUR/USD): With rate-cut hopes already pared back, any upside surprise in US inflation or consumption data could further support the dollar and push EUR/USD toward 1.158 as highlighted by technical analysts. Downside misses could accelerate the structural dollar selloff that marked early 2026.

2. US-Iran ceasefire/deal progress (ongoing, sensitive pair: USD/JPY, USD/CHF safe havens): The Strait of Hormuz situation remains the single largest near-term binary risk. A confirmed deal would likely weigh on safe-haven positions, boosting risk currencies (AUD, EM) and weakening JPY and CHF on a relative basis. Renewed escalation would reverse those flows.

3. USD/JPY at 160.71 resistance (technical trigger, BOJ speech risk): USD/JPY is approaching key technical resistance at 160.71 highlighted by ActionForex. Any BOJ communication suggesting willingness to hike rates or intervene could produce a sharp reversal. Watch for BOJ governor commentary in the coming days.

4. EUR/USD near-term trend (week ahead): Forex.com's May 26 "Currency Pair of the Week" piece flags near-term downside tilt for EUR/USD, with the pair testing 1.158 as a potential support/target. A break below that level would mark a new leg down from the 1.1645 highs; a rebound targets 1.1700+.

Reader Action Items

1. EUR/USD: Watch 1.158 as the key downside level. The pair is caught between Middle East safe-haven flows and structural ECB-vs-Fed divergence. A confirmed Hormuz ceasefire could see a brief recovery to 1.17; sustained dollar strength and fading deal hopes risk a break below 1.158.

2. USD/JPY near 160: Manage carry trade risk. The pair is approaching major resistance at 160.71. Long USD/JPY carry positions remain vulnerable to sudden BOJ intervention or hawkish signaling — keep stops tight above this technical level.

3. EM outperformers BRL and MXN deserve attention. Both currencies are materially stronger YTD despite global uncertainty. BRL's -11% YoY move against the dollar is exceptional — monitor Brazil's central bank (BCB) signals and commodity prices for any reversal catalyst before adding to EM risk positions.
