Today's headlines: Iran's Revolutionary Guard claims it struck the US Fifth Fleet headquarters. The US Air Force bombed Iran's Qeshm Island. A Hellfire missile hit an Iranian-linked oil tanker. Airports in Bahrain, the UAE, and Kuwait suspended operations due to airstrikes.
This isn't a drill. It's the latest chapter in the US-Iran conflict that's been escalating since February 2026.
If you trade forex, you've already felt it — Brent crude rocketed from $73.50 pre-war to $120 in early March before settling around $95. Gold hovers near $4,500. USD/JPY pushed from the 150 range at the start of the year to nearly 160. If your trading plan was set in January, it's already disconnected from reality.
What's actually happening
On February 28, 2026, the US and Israel launched a joint military operation against Iran. The situation escalated rapidly.
The critical chokepoint is the Strait of Hormuz. Roughly 20% of the world's oil supply flows through this narrow passage, with 80% of it heading to Asia. The IEA has described the disruption as the "largest supply disruption in the history of the global oil market" — global oil output is expected to fall by 6.9 million barrels per day (6.6%) year-on-year in Q2 2026, the steepest quarterly decline since the COVID-19 pandemic.
The Dallas Fed's model estimates that the Hormuz disruption will push average WTI prices to $98 per barrel in Q2 2026, while dragging global real GDP growth down by an annualized 2.9 percentage points.
This isn't "could affect markets." Markets are already being affected.
Five assets, five different stories
Oil: from $73 to $95, and it's not over
Brent crude was at $73.50 before the war. It spiked to $120 in early March. It's now sitting around $95. WTI is near $91.
Don't mistake the pullback for safety. As long as the Strait of Hormuz remains at risk, oil can spike again without warning. On June 1, WTI jumped 5.9% in a single session. The next day it gave back 1%. That kind of volatility is a nightmare for anything correlated to oil.
What it means for your trades: If you're trading USD/CAD or USD/NOK, every oil price swing hits your P&L directly. Canada and Norway are major oil producers — when oil rises, their currencies strengthen.
US dollar: still king, but the logic is shifting
Geopolitical crisis = capital flows into the dollar. That formula is still working. The Dollar Index has been climbing since the conflict began. USD/JPY is approaching 160.
But there's a subtlety here: dollar strength isn't just safe-haven driven. Fed rate hike expectations are adding fuel — we covered this in detail in our previous article. Two forces stacking means dollar strength could last longer than you think.
If you're short the dollar, pay attention. With geopolitical risk plus hawkish Fed expectations both supporting it, pullbacks could be shallow.
Japanese yen: the safe haven that isn't
Traditional logic says the yen should strengthen during geopolitical crises. In 2026, reality says otherwise. The yen's safe-haven status is eroding.
The reason is straightforward — Japan imports the vast majority of its crude oil from the Middle East. When the Strait of Hormuz gets choked, Japan's energy import bill explodes, economic outlook deteriorates, and the yen weakens. USD/JPY moved from 150 to 160, doing the exact opposite of what the safe-haven playbook predicts.
The Bank of Japan's ultra-low rate policy makes things worse. The interest rate differential is so wide that carry trades keep pressing the yen lower.
Trading takeaway: Stop treating JPY as a pure safe haven. Shorting USD/JPY in this environment carries more risk than you might assume.
Swiss franc: the real safe-haven winner
The actual safe-haven champion of 2026 is the Swiss franc. CHF gained nearly 13% against the dollar over the past year and keeps strengthening.
It's not hard to see why: Switzerland is neutral, economically stable, and doesn't depend on Middle Eastern oil. When global capital searches for a safe harbor, the franc is a cleaner choice than the yen.
But CHF strength carries its own risk — the Swiss National Bank (SNB) has started hinting at potential intervention. If USD/CHF keeps falling (CHF keeps rising), the odds of the SNB stepping in grow. If you're long CHF, watch central bank rhetoric closely.
Gold: the tug-of-war at $4,500
Gold is trading around $4,500. The 52-week range is $3,247 to $5,595 — that range alone tells you how wild this market has been.
Gold is caught between two forces:
- Support: Geopolitical crisis → safe-haven demand → gold up
- Resistance: Strong dollar + rising Treasury yields → higher opportunity cost of holding gold → gold down
The two forces are deadlocked near $4,500. A breakout in either direction will trigger a sharp move.
If you're trading gold, position sizing matters more than directional calls right now.
5 things forex traders should do right now
1. Cut your position sizes
Geopolitically driven markets have a specific characteristic: breaking news can blow through your stop loss in minutes. A missile, a statement, a failed negotiation — any headline can gap the market.
In this environment, your position sizes should be 50-70% of normal. Use the position size calculator to recalculate. Make sure no single trade risks more than 1% of your account. If you're rusty on the fundamentals of risk control, our forex risk management guide covers the framework — every principle in it matters twice as much right now.
2. Widen stops, don't remove them
Many traders remove stop losses during high volatility, reasoning they'll "just get stopped by fakeouts anyway." This is the most dangerous move you can make.
The right approach: widen the stop but shrink the position. If you normally trade EUR/USD with a 50-pip stop on 1 lot, switch to an 80-pip stop on 0.6 lots. Same total risk, but the price has room to breathe.
3. Check your correlation exposure
The Middle East conflict doesn't just affect one or two pairs — it moves everything simultaneously through three channels: oil prices, risk sentiment, and rate expectations.
If you're long XAU/USD and short USD/JPY at the same time, thinking they're two independent trades — they're not. Both are bets on dollar weakness. If the dollar surges, both lose.
Run your entire portfolio through the margin calculator to see your true aggregate exposure.
4. EA users: turn on news filters
If you're running EAs, geopolitical news events are your biggest risk. A single headline about ceasefire talks or military escalation can move the market 100+ pips in seconds.
When the conflict broke out in March, we got flooded with support tickets. Almost every grid EA user got wiped. One trader was running a 500-pip grid on XAU/USD — gold moved 1,800+ pips in a single day, blew through three grid layers, and the account was gone by evening. That wasn't an outlier. That was a normal week in March.
Recommendations:
- Pause EAs 30 minutes before and after major news events
- Grid and martingale strategies are extremely dangerous in trending markets — consider shutting them down temporarily
- If your EA doesn't have a news filter, check our guide on EA news filter setup
- Trend-following EAs can actually thrive in this kind of environment, but only if your backtests cover similar high-volatility periods
5. Update your pip values and margin calculations
Large exchange rate moves mean your pip values have changed. USD/JPY going from 150 to 160 drops the dollar value of a standard-lot pip from $6.67 to $6.25. XAU/USD going from $3,000 to $4,500 may have doubled your margin requirements for the same lot size.
Use the pip calculator and profit calculator to update the actual numbers on all your open positions.
What comes next
Three scenarios, three playbooks:
Scenario 1: Further escalation Oil pushes back toward $120+. Gold breaks above $5,000. Dollar keeps climbing. Emerging market currencies crash. Playbook: minimum position sizes, stick to long USD and long CHF.
Scenario 2: Ceasefire progress Oil drops quickly to the $70-80 range. Gold pulls back. Dollar gives up gains. JPY and EM currencies bounce. Playbook: prepare reversal setups, but wait for confirmation before entering.
Scenario 3: Stalemate (most likely right now) Oil oscillates between $85-100. Gold consolidates in the $4,200-$4,800 range. Dollar stays firm but doesn't accelerate. Playbook: range trading, strict stops, don't chase breakouts.
Regardless of which scenario plays out, one thing is certain: volatility is not going back to early-year levels.
Internally, we cut position sizes on all our live EA accounts by half in March and bumped our ATR multiplier from 1.0 to 1.5. The result: lower returns, but zero blown accounts. In this kind of market, not losing is winning. Your trading system and risk parameters need the same recalibration for a high-volatility baseline.
FAQ
How does the Middle East conflict affect EUR/USD?
EUR/USD faces pressure from both sides: safe-haven dollar buying pushes it down, while Europe's economy takes a hit from elevated oil prices (the eurozone is a net oil importer), weakening the euro's fundamentals. Unless there's a clear ceasefire signal, EUR/USD upside is limited. That said, markets can "buy the rumor, sell the fact" — a surprise ceasefire headline could trigger a 200+ pip EUR/USD spike.
Should I close everything and wait for the conflict to end?
Depends on your strategy and risk tolerance. Day traders: keep trading, but cut position sizes and widen stops. Swing traders: check if your positions align with the current macro trend — being short USD or long JPY on a medium-term basis is high risk right now. If you're unsure, scaling down to 30% of normal size isn't cowardice. Staying alive matters more than making money.
Which currency pairs are most affected by rising oil prices?
Most directly: USD/CAD (stronger CAD = pair falls) and USD/NOK (stronger Norwegian krone). Secondary impact: USD/JPY (Japan depends on Middle Eastern oil imports, yen weakens) and EUR/USD (eurozone energy costs rise). AUD/USD also gets hit — Australia exports energy, but in extreme risk-off environments, capital exits high-beta currencies like the Aussie first.
