How Middle East conflicts impact Oceania through energy and shipping shocks: the triple transmission to the Australian, New Zealand, and Pacific economies

How Middle East conflict transmits to Oceania through energy and shipping shocks: the threefold transmission to Australia, New Zealand and Pacific economies

The OECD’s latest World Economic Outlook sends a clear signal: the impact of geopolitical conflict on the global economy is no longer confined to the place where the conflict occurs. The report expects global growth to slow from 3.4% in 2025 to 2.8% in 2026, before rebounding to 3.1% in 2027. One of the main reasons is that the Middle East situation has disrupted shipping through the Strait of Hormuz, pushed up energy and fertilizer prices, and weakened the stability of global supply chains.

For Oceania, such shocks are usually transmitted not through a single trade channel, but through the combined effects of energy costs, shipping insurance, food prices and investment expectations. Although Australia, New Zealand and the Pacific island countries differ markedly in industrial structure, resource endowment and financial buffers, they are all part of the same Asia-Pacific trade network, and therefore can hardly remain unaffected by global energy and transport shocks.

Background: Why global shocks affect Oceania

The OECD noted in the report that conflict has led to a significant contraction in global oil and gas supply, driving up energy and fertilizer prices. This assessment is especially important for Oceania, because the region’s economies are highly dependent on transoceanic transport and external markets: Australia and New Zealand’s exports are dominated by commodities, agricultural products and services; Pacific island countries are even more reliant on imported fuel, food and basic consumer goods, while tourism and remittances are highly sensitive to the external environment.

What makes Oceania distinctive is that it is both a resource-exporting region and a long-distance trading region. Changes in international oil prices and shipping rates affect not only production costs, but also export profits and final consumer prices. In other words, the impact of the Middle East situation on Oceania often appears first in freight rates, fuel prices and business expectations, and only then gradually transmits to GDP, inflation and fiscal space.

In-depth analysis: differentiated impacts on Australia, New Zealand and Pacific island countries

1) Australia: resource exports benefit, but costs and inflation pressures rise

Australia is one of the most shock-resilient economies in Oceania. The reason is that its resource-export structure allows some sectors to benefit when global energy prices rise, especially energy and mining-related companies. At the same time, Australia is also an open economy heavily dependent on shipping, and rising fuel and logistics costs will squeeze margins in manufacturing, retail and agricultural exports.

More importantly, global uncertainty often affects capital flows and financing costs. If the Middle East conflict leads to prolonged energy price volatility, Australia’s inflation expectations, the pace of monetary policy and corporate investment plans could all be affected. For the federal budget, short-term resource income may provide a buffer, but if global growth slows simultaneously, weakening external demand will also offset some of the gains.

2) New Zealand: food exports are resilient, but import costs and tourism are more vulnerableNew Zealand’s economy is more sensitive to changes in global transportation costs and consumer demand. Its exports of dairy products, meat, and seafood rely heavily on stable Asian markets and international logistics networks. Once fuel and shipping costs rise, export prices may be supported by higher global food prices, but net gains do not necessarily improve at the same pace, because transportation and input costs also increase.

At the same time, New Zealand’s domestic economy relies heavily on the recovery of tourism, international education, and services trade. The OECD report emphasizes that the recovery of services exports is usually slower than that of goods exports because it depends on international flights and the movement of people. For New Zealand, this means that if global risk appetite declines and aviation costs rise, the recovery of the services sector will be more fragile than that of merchandise exports.

3）Pacific Island countries: fuel and logistics costs are the most direct shock

For Pacific Island countries, the issue is more concentrated and more immediate: rising prices for imported fuel and food directly hit household purchasing power, public transport, utilities, and government budgets. Island economies generally have small market sizes, long transport chains, and limited alternative supply channels, so external price fluctuations are more easily translated into pressure on the cost of living.

Such shocks also affect development financing and infrastructure implementation. Ports, airports, power grids, and water supply projects in island countries often depend on external funding and imported equipment, and if the global financing environment tightens, project approvals and construction timelines may both be prolonged. For island countries already dealing with pressure from climate resilience and post-disaster recovery, rising energy and logistics costs will further squeeze fiscal space.

Regional Implications: What does this mean for Oceania as a whole

From a regional perspective, this round of shocks once again proves that what matters most for Oceania’s economies is not just local demand, but “long-distance connectivity.” If oil prices, sea freight rates, and insurance costs remain high, trade efficiency across the entire region will decline, especially on trans-Pacific routes and supply chains connecting to Asian markets.

This has three implications for regional development:

First, the economic logic of the energy transition is stronger. Pacific economies that remain dependent on imported fuel for the long term will continue to be exposed to geopolitical risks and price volatility. The OECD report’s discussion of how energy independence can buffer shocks, although aimed at Israel, also offers lessons for Oceania: distributed solar, energy storage, grid upgrades, and regional energy cooperation are no longer just climate issues, but macroeconomic stability issues as well.

Second, port and shipping resilience has become part of trade competitiveness. For Australia and New Zealand, port efficiency, cold-chain capacity, and shipping diversification will directly affect export profits. For island countries, port modernization and regional shipping connectivity are tied to import prices and supply security.

Third, development financing needs to place greater emphasis on “resilience returns.” Infrastructure projects in the past were often driven mainly by growth, but in a highly uncertain environment, risk resistance, supply chain continuity, and energy self-reliance are themselves part of the investment return.## Trade Impact: Asian Markets and Regional Corridors Remain Central

Trade ties between Oceania and Asia are continuing to deepen. Australia’s dependence on China and ASEAN markets, New Zealand’s reliance on Asian food demand, and Pacific island countries’ dependence on transshipment and aid networks in Australia and New Zealand all mean that external shocks to the region will be amplified.

When global shipping and energy costs rise, what is affected first is often not the price of a single commodity, but trade flows and the pace of corporate orders. For agricultural exporters, profit comes from the net value after “sale price minus transport and input costs”; for mining and energy companies, higher global prices may bring gains, but if end demand slows, those advantages will also weaken.

In the long run, Asian markets remain the center of Oceania’s exports, but regional competition will also intensify. Whoever can build stable, low-carbon, and predictable supply chains faster is more likely to gain greater market share in the coming years.

Investment Impact: Capital Will Tilt Further Toward Resilient Assets

The OECD notes that the core uncertainty of geopolitical risk comes from “whether sustained conflict will emerge.” Such uncertainty often pushes capital toward assets that are more stable and less substitutable: energy infrastructure, port logistics, cold chains, energy storage, grid upgrades, and digital connectivity.

For Australia and New Zealand, investment opportunities may be more concentrated in the energy transition, agricultural processing, and infrastructure upgrades. For Pacific island countries, foreign capital and development institutions are more likely to focus on renewable energy, microgrids, port redevelopment, and climate resilience projects. In other words, Oceania’s investment logic in the future will not just be about “where growth is,” but also about “where operations can keep running under external shocks.”

Long-Term Trends: Possible Changes over 3, 5, and 10 Years

Next 3 years: Oceania companies will place greater emphasis on cost predictability. Energy procurement, shipping contracts, and inventory management will all become more conservative, and fiscal and monetary policy will pay more attention to imported inflation risks.

Next 5 years: The priority of infrastructure investment within the region will continue to rise, especially in ports, power grids, renewable energy, and digital connectivity. Pacific island countries may rely more heavily on multilateral development institutions and regional cooperation mechanisms to share risks.

Next 10 years: If the energy transition proceeds smoothly, Oceania’s sensitivity to external oil and gas shocks may decline; but if grid upgrades, energy storage, and cross-border interconnection lag, the region will remain exposed to global price volatility for a long time. For Australia and New Zealand, the upgrading of export structures will determine their position in Asian supply chains; for island countries, infrastructure resilience will determine the ceiling of development.

Conclusion

The real significance of this OECD outlook lies not only in its downward revision of global growth expectations, but also in its reminder to the world that the impact of geopolitical conflict on the economy is continuously reshaping regional economies far from the front lines through energy, shipping, and investment confidence.For Oceania, the focus of this round of shock is not short-term price fluctuations, but long-term structural choices: whether to continue relying on high-cost external energy and a single shipping corridor, or to accelerate the energy transition, port upgrades, and regional interconnection. Australia and New Zealand have stronger buffering capacity, but Pacific island countries are more vulnerable, and therefore need even more to place “resilience” at the core of their development strategies.

From the perspective of the Oceania Economic Review, this global shock once again shows that the future of regional competitiveness depends not only on how much is exported, but also on who can more steadily connect with Asian markets, maintain trade flows, and safeguard development gains when global uncertainty rises.
