The US dollar strengthened after President Trump announced a blockade of Iranian ports from 10ET, following failed peace talks over the weekend. Markets also saw weaker stocks and bonds, alongside a rise in oil prices.
The US Dollar Index (DXY) fell back from its earlier Asian-session peak. That peak only slightly rose above 99.2, the intraday high set on Wednesday after Tuesday’s ceasefire announcement.
Dollar Trend Still Under Pressure
Despite the firmer dollar, the rebound in DXY has been limited so far. Recent price action still points to a bearish bias after a sharp fall last week.
The market moves have stayed relatively contained, suggesting traders are waiting for details on the blockade’s scope and its effect on growth. The report also notes that a prolonged period of very high oil prices could harm global growth, with Asian countries most exposed if Gulf supply is reduced.
We are seeing the expected market reaction following last year’s announcement in 2025 of a blockade on Iranian ports. The US dollar has firmed up, while stocks and bonds have weakened due to the geopolitical tension. This initial response, however, seems contained as markets await further clarity on the blockade’s true economic impact.
The most significant move has been in energy, with Brent crude recently surging past $115 a barrel, a level not seen in over two years. This has caused the CBOE Crude Oil Volatility Index (OVX) to spike over 30%, making options strategies much more expensive. Traders should anticipate that call options on oil will remain in high demand as long as the blockade holds.
Key Risks For Investors
While the dollar initially strengthened, the Dollar Index (DXY) is struggling to break key resistance at the 100 level, currently hovering near 99.5. This lackluster follow-through supports the view we held back in 2025 that the dollar’s broader trend remains bearish. This suggests any de-escalation could trigger a sharp reversal, making aggressively long dollar positions risky.
Equity markets are clearly nervous, reflected by the VIX jumping from a low of 18 to over 24 as the S&P 500 slid on the news. This environment makes hedging long portfolios with index puts a priority. Selling volatility through strategies like short straddles is extremely dangerous until tensions show clear signs of subsiding.
We saw a similar dynamic back in 2022 when geopolitical events caused Brent crude to spike towards $140 a barrel, contributing to severe inflation and aggressive central bank action. That period reminds us how a sustained oil shock can damage corporate earnings and slow global growth for several quarters. The current situation could easily follow the same playbook if the blockade is prolonged.
The damage to global growth will likely hit Asian economies the hardest, given their reliance on energy imports from the Gulf. We should therefore consider positioning for weakness in oil-importing emerging markets. This could involve buying puts on relevant country-specific ETFs or shorting currencies like the Indian Rupee and Thai Baht.
