Energy Market Jumps as U.S. Begins Blockade of Strait of Hormuz
US President Donald Trump took to Truth Social on Monday to confirm his country has begun blocking ships from entering or exiting Iranian ports, while threatening the Islamic Republic that if any of their "fast attack ships" approach the blockade, they will be "immediately ELIMINATED."
The U.S. on Monday has begun blocking ships from entering or exiting the Strait of Hormuz, attempting to ratchet up pressure on Iran to reopen the key oil route after peace negotiations collapsed. President Donald Trump, announcing the plan Sunday on Truth Social, slammed Iran for refusing to give up its nuclear ambitions and accused Tehran of “WORLD EXTORTION” by continuing to throttle traffic through the strait. The U.S. blockade was set to begin at 10am ET.
US President Donald Trump took to Truth Social on Monday to confirm his country has begun blocking ships from entering or exiting Iranian ports, while threatening the Islamic Republic that if any of their "fast attack ships" approach the blockade, they will be "immediately ELIMINATED."
More than 15 American warships are currently deployed to support ongoing blockade operations in the Strait of Hormuz, the Wall Street Journal reported on Monday, citing a senior US official. The outlet further stated that the warships would likely operate outside the Strait of Hormuz to avoid Iranian fire.
According to Navy and Central Command sources, the United States has an aircraft carrier, several guided-missile destroyers, an amphibious assault ship, and numerous additional warships in the Middle East. Some of these ships can marshal commercial vessels to certain locations to keep them in place, and others can launch helicopters to assist with boarding operations.

There was little in the way of data during the day, while investors' attention remained focused on geopolitical events and their ramifications for the global economy. Lingering uncertainty about the future of the Middle East and the possibility of resumption of hostilities between the US and Iran appeared to continue to weigh down on the markets.

Trader’s Playbook: Where the Real Opportunities Are
Now let’s translate this into what actually matters—how to position in the market.
This is a textbook geopolitical risk event, and the reaction across asset classes follows a clear pattern:
- Oil surges
- Equities drop
- Safe-haven demand rises
- Risk currencies weaken
This is not random movement—this is institutional capital reallocation.
1. Oil Is the Engine of This Move
The entire market reaction starts with Crude Oil.
With the blockade around the Strait of Hormuz, supply fears increase immediately.
What to expect:
Strong bullish momentum. Volatility spikes. Breakout opportunities.
Trading angle:
Focus on continuation and breakout trades, not reversals.
2. USD Strength – The Safe Haven Flow
In times like this, money flows into the US dollar.
Why?
- Global uncertainty rises
- Liquidity becomes priority
- Institutions reduce risk exposure
Market impact:
- EURUSD ↓
- GBPUSD ↓
- Risk currencies weaken
Trading angle:
Look for sell setups on rallies (pullbacks) in major USD pairs.
3. Indices Under Pressure
Equities are reacting exactly as expected.
Dow Jones Industrial Average ↓
S&P 500 ↓
Nasdaq-100 ↓
We saw this in the form of a gap down on these indexes on Monday. This reflects risk-off sentiment.
Trading angle:
- Intraday sell opportunities
- Breakdowns below key support levels
- Momentum continuation trades
4. USDCAD – A High-Probability Pair
This is where it gets interesting.
Normally, rising oil strengthens CAD—but during strong risk-off environments, USD demand could dominate.
What to do?
Watch out for trade opportunity on either side of the divide. Watch for bullish/bearish continuation setups, especially during volatility spikes.
