Stock markets across the Gulf have moved in sharply different directions since the Iran war began, as investors respond unevenly to surging oil prices, geopolitical risk and fears over regional economic disruption.
While Saudi Arabia and Oman have emerged as relative winners from the turmoil, Dubai has suffered the steepest losses, exposing how conflict in the Middle East is reshaping investor sentiment across the region.
Analysts say the divergence reflects the varying structures of Gulf economies and stock markets. Oil-linked bourses such as Saudi Arabia’s have benefited from the surge in crude prices, while markets more exposed to property, tourism and consumer confidence such as Dubai have come under pressure.
According to market data cited by CNBC, Oman’s benchmark index has risen about 9.3 percent since March 1, while Saudi Arabia’s Tadawul has gained around 5.8 percent. In contrast, Dubai’s DFM General Index has fallen nearly 16 percent, with Bahrain and Qatar also posting losses.
The contrast has been amplified by the energy shock caused by the war. Brent crude has hovered near or above US$100 per barrel in recent weeks as the conflict threatened shipping and energy flows through the Strait of Hormuz, one of the world’s most critical oil transit routes. Reuters has reported that repeated attacks and security threats have disrupted Gulf energy infrastructure and heightened fears of wider supply shocks.
Saudi Arabia’s market has drawn support from higher oil prices and the dominant weight of energy-related firms, especially Saudi Aramco. Reuters reported this week that the Saudi market managed to post gains even as other Gulf bourses weakened under conflict-related uncertainty.
Oman, meanwhile, has benefited from what some strategists describe as a regional safe-haven bid, helped by investor confidence in its longer-term diversification strategy under Vision 2040.
Dubai, by contrast, has been more vulnerable. Its economy is heavily tied to real estate, tourism, retail and international capital flows—sectors that tend to be highly sensitive to geopolitical shocks and perceptions of regional instability. Although the market staged a temporary rebound midweek on hopes of a ceasefire, Reuters said those gains quickly faded as uncertainty over diplomacy persisted.
That volatility has become a defining feature of Gulf markets over the past month. On some days, equity indices have swung sharply on reports of possible U.S.-Iran negotiations, only to retreat again after renewed military threats or retaliation warnings. Reuters reported that investor optimism over a possible ceasefire proposal briefly lifted markets on Wednesday, but sentiment remained fragile by Friday.
Beyond stock prices, the broader concern for investors is whether the war could trigger a longer period of inflation, supply disruption and reduced regional confidence.
For Gulf economies with currencies pegged to the U.S. dollar, imported inflation remains a particular concern if oil prices stay elevated and global financial conditions tighten further. Investors are also closely watching whether the conflict could cross more dangerous red lines, especially attacks on energy infrastructure, desalination plants or shipping routes that underpin the Gulf’s economic stability.
Despite the turbulence, analysts say the region is not without opportunities. Saudi Arabia continues to attract interest in energy, infrastructure and pre-IPO assets, while some investors are selectively buying into market weakness where domestic fundamentals remain strong.
Still, caution is dominating strategy for now.
Many fund managers are avoiding aggressive positioning until there is clearer visibility on whether diplomatic efforts can contain the conflict or whether the region is headed for a more prolonged shock.

For Gulf markets, the message is increasingly clear: while some economies may gain from higher oil prices, the war is exposing how unevenly geopolitical risk is priced across the region—and how quickly sentiment can splinter when stability is no longer taken for granted.
