The US blockade of the Strait of Hormuz is increasing volatility as shipping traffic expectations plummet, impacting traders' confidence.

Shipping officials have raised alarms regarding the increasing instability caused by the U.S. blockade of the Strait of Hormuz. As Iran escalates its efforts to keep the strait closed, recent reports indicate that traffic is not rebounding as expected. As of now, the likelihood of traffic normalizing by May 15 has decreased to 13.5%, down from 20%.

The heightened unease among shipping officials has led to a significant drop in confidence among investors, reflected in the related Polymarket contracts. The probability of former President Donald Trump announcing a lift on the blockade by May 31 has now fallen to 53.5%, a drop from 72% just a day prior. Traders are adjusting their strategies to account for ongoing tensions and the possibility of a prolonged escalation in the region.

In terms of trading volumes, the Strait of Hormuz traffic market currently sees daily trades exceeding $36,459 in real USDC. Notably, a single $4,658 order can influence price movements by five percentage points, indicating that substantial trades could lead to sharp fluctuations. Conversely, the market for Trump’s blockade announcement is more fluid, with about $95,253 traded daily, although the largest single movement over the past day was a mere five-point spike.

For those considering a position, buying YES on the potential return of normal traffic by mid-May at a price of 14¢ could yield a significant 7.14x return if resolved favorably. However, achieving this outcome will require clear indications of de-escalation or a crucial diplomatic breakthrough.

Investors should monitor updates from CENTCOM, any changes in Iran’s military stance, and insights from shipping analytics. Key announcements from figures like General Michael Kurilla or the Iranian Foreign Minister could have immediate effects on the markets.
