Introduction

The blockade of the Strait of Hormuz, caused by military conflicts between the United States, Israel, and Iran, has led to a sharp increase in energy costs and higher inflation within the United States.

Main Body

The current instability began on February 28 after US and Israeli military actions against Iran, which led Tehran to block the Strait of Hormuz. Because this waterway handles about 20% of the world's oil and gas, the blockade has seriously limited the supply. Although crude oil prices have recently dropped below $100 per barrel due to negotiations, gas prices for consumers remain high. In the US, the average price reached $4.504 per gallon by May 12, although prices vary by region; for example, North Carolina averages $4.145, while West Coast states like California and Washington are much more expensive. From an economic perspective, the Labor Department reported that the Consumer Price Index (CPI) rose by 3.8% in April 2025. The energy sector saw the most significant changes, with a 17.9% annual increase. While core inflation—which excludes food and energy—is lower at 2.8%, overall inflation is still above the Federal Reserve's 2% target. Consequently, this environment has hurt company profits. For instance, Whirlpool reported a 10% drop in revenue, which the company blamed on a recession-level decline in the industry and lower consumer confidence. Government and institutional responses have been inconsistent. The Federal Reserve has been cautious about changing interest rates while it waits for more data on the conflict. This has caused tension with the government, as President Trump has criticized the Federal Reserve for not lowering rates. Furthermore, the possible appointment of Kevin Warsh to replace Jerome Powell creates more uncertainty about future policy. Meanwhile, financial markets now believe that the Strait of Hormuz will not reopen in the near future.

Conclusion

The United States continues to face high consumer prices and economic instability as a direct result of the blockade of the Strait of Hormuz and the limited supply of energy.

⚡ The "Cause and Effect" Leap

To move from A2 to B2, you must stop using 'because' for everything. A2 students describe the world in simple fragments. B2 students connect ideas using Logical Connectors to show how one event forces another to happen.

🛠️ The Upgrade Path

Look at how the article describes the energy crisis. Instead of saying "The supply is low because of the blockade," it uses sophisticated triggers:

  • "Led to..." →\rightarrow The conflict led to a sharp increase in costs. (Use this when one event creates a direct result).
  • "Consequently..." →\rightarrow ...overall inflation is still above the target. Consequently, this environment has hurt profits. (Use this at the start of a sentence to show a logical conclusion).
  • "Due to..." →\rightarrow ...dropped below $100 per barrel due to negotiations. (This is a professional replacement for 'because of').

🔍 Contrast Logic

B2 fluency requires balancing two opposite facts in one sentence. The article uses "While" and "Although" to do this:

"While core inflation... is lower at 2.8%, overall inflation is still above the target."

The Rule: If you use While or Although at the start, you are telling the reader: "I am giving you one fact, but the second fact is the more important one."

💡 Vocabulary Shift: Precision

Stop using "big" or "bad." Use Impact Verbs:

  • Instead of "big change" →\rightarrow "Significant changes"
  • Instead of "bad drop" →\rightarrow "Recession-level decline"
  • Instead of "not sure" →\rightarrow "Creates uncertainty"
