The Gulf for case solvers

Saudi Arabia, the UAE, Qatar, Kuwait, Oman and Bahrain. Size, oil and diversification, citizens and foreign residents, new taxes, the 2026 war, and what they mean in a case.

Key takeaways

  • The six Gulf Cooperation Council (GCC) states are rich, small in population and built on oil and gas.
  • Saudi Arabia: the largest market (USD 1,277 billion of GDP, 36.0 million people).
  • United Arab Emirates: a trade, travel, finance and logistics hub (USD 572 billion, 11.4 million people).
  • Qatar: the richest per person (about USD 69,680) and a major exporter of liquefied natural gas (LNG).

Key idea

The six Gulf Cooperation Council (GCC) states are rich, small in population and built on oil and gas. Together they had about USD 2.4 trillion of GDP and 62.6 million people in 2025. Their governments are spending heavily to diversify, and the 2026 war in the region hit them hard. Gulf cases turn on three things. The state is a buyer and investor. Citizens and foreign residents differ. And tax rules are still being written.

So-what

Saudi Arabia is over half the region's GDP and population. Qatar is the richest per person and was projected to be hit hardest in 2026.

The war in the Middle East began on 28 February 2026. The IMF's April 2026 regional outlook described the closure of the Strait of Hormuz (the narrow sea passage out of the Gulf). It also described the disruption of oil and gas production. It expected outright contractions in 2026 in five of the eight oil exporters around the Gulf, including Bahrain, Kuwait and Qatar. Its July 2026 update cut Saudi Arabia's 2026 growth forecast to 1.7 percent (5.5 percent in 2027), as a country with more export routes. Kuwait and Qatar are among the most affected producers. The IMF expected them to shrink sharply in 2026 before double-digit rebounds in 2027. It assumed the Strait would begin to reopen in mid-July 2026, with conditions broadly back to normal by March 2027. That reopening had not happened by the start of October. The September 2026 report of the IEA (International Energy Agency) said more than 10 million barrels a day of Gulf output was still shut in during August. In the week of 14 to 20 September, Lloyd's List Intelligence counted only 104 transits by larger ships not linked to Iran, about 15 a day. It rated the threat to shipping as severe (as reported). Treat the IMF path as an assumption, not an outcome.

So-what

Almost everyone lives in cities and very few people are old, partly because many residents are working-age foreign workers.

Structure of the economy

Oil and gas sit inside "industry" in the World Bank's figures. In Saudi Arabia industry is 43.0 percent of GDP and services 48.9 percent. Manufacturing (refining and petrochemicals among it) is 15.8 percent. State oil and gas companies, sovereign wealth funds (state investment funds) and government budgets drive much of the rest of the economy. They work through construction, tourism, logistics and finance.

Each state in brief

  • Saudi Arabia: the largest market (USD 1,277 billion of GDP, 36.0 million people). A national programme, Vision 2030, aims to build an economy less dependent on oil. The Public Investment Fund (the sovereign fund) leads many of its projects. Non-Saudis were 41.6 percent of the population in the 2022 census. Unemployment among Saudi nationals was 6.4 percent in the first quarter of 2026. VAT is 15 percent. Regulators include the Saudi Central Bank (SAMA), the Ministry of Investment and the Zakat, Tax and Customs Authority (ZATCA).
  • United Arab Emirates: a trade, travel, finance and logistics hub (USD 572 billion, 11.4 million people). It has many free zones where foreign firms can usually own the whole company. Federal corporate tax is 9 percent on taxable income above AED 375,000, for financial years starting on or after 1 June 2023.
  • Qatar: the richest per person (about USD 69,680) and a major exporter of liquefied natural gas (LNG). Its state company, QatarEnergy, is expanding output toward 142 million tonnes a year. The last stage is expected to start producing by the end of 2031. The 2026 war disrupted its LNG operations. QatarEnergy declared force majeure (it could not deliver as contracted) in March 2026. It was reported on 28 September 2026 to have extended it to shipments in November and early December.
  • Kuwait: an oil economy (USD 158 billion, 5.1 million people) with a large sovereign fund. It introduced a 15 percent minimum tax on large multinational groups from 1 January 2025.
  • Oman: smaller and less rich per person (about USD 20,000). It has passed a personal income tax of 5 percent for individuals with total income above OMR 42,000 a year, starting in 2028.
  • Bahrain: the smallest economy (USD 48 billion, 1.6 million people), with a long-standing banking and finance sector.

What changed in 2024 to 2026

  • The 2026 war and the closure of the Strait of Hormuz cut oil and gas exports and output. Shipping through the strait was still heavily restricted at the start of October 2026. The deepest damage was in Qatar, Kuwait and Bahrain, with a smaller hit to Saudi Arabia, the UAE and Oman.
  • Interest rates rose with the Fed: most Gulf currencies are pegged to the US dollar, so their central banks follow US rates. On 16 September 2026 the Saudi Central Bank raised its repo rate (its main policy rate) to 4.50 percent. The UAE central bank raised its base rate to 3.90 percent from 17 September. Kuwait pegs its dinar to a basket of currencies and can move differently.
  • Taxes spread. The UAE has had a corporate tax since 2023. The UAE and Kuwait both added a 15 percent minimum tax on large multinational groups from 2025. Oman will tax high personal incomes from 2028.
  • Saudi Arabia opened property ownership to non-Saudis under a new law that took effect on 22 January 2026.

What this means in a case

  • The state is often the customer, the investor and the regulator at once. Sales cycles run through ministries, state companies and sovereign funds, and many contracts favour local partners and local hiring.
  • There are two consumer markets in one country: citizens and foreign residents, with very different incomes, family sizes and needs. Size them separately.
  • Model taxes and risks explicitly. Tax and ownership rules changed often between 2023 and 2026. The 2026 war showed how much depends on one shipping route. So ask about supply routes and stock levels in any Gulf operations case.
Timed math drill

A UAE company has taxable income of AED 500,000. Corporate tax is 0 percent up to AED 375,000 and 9 percent on income above that. How much corporate tax does it pay, in dirhams?

The six Gulf economies had GDP of about USD 2,382 billion in 2025 (IMF), of which Saudi Arabia was USD 1,277 billion. What share of the region's GDP is Saudi Arabia, in percent?
