Governments and businesses across the Asia-Pacific region are closely monitoring the US midterm elections, seeking significant changes in President Donald Trump's foreign and trade policies, particularly concerning the war on Iran and existing tariffs. Analysts suggest that while the elections might bring "enormous changes" in US policy, few anticipate immediate shifts, even with Democrats potentially gaining control of the House and Senate.

The Asia-Pacific region has been disproportionately affected by the conflict in Iran, which began in January. Prior to the war, the region was a major recipient of oil and gas transiting the Strait of Hormuz. Iran's closure of this vital chokepoint led to widespread shortages and economic strain across Asia.

Steven Okun, a trade specialist and CEO of APAC Advisors, noted the global attention on the US political theater. He highlighted that the Philippines, which imports over 90 percent of its crude oil from the Gulf, has been under a national energy emergency since March due to the conflict. Poorer economies like Cambodia, Laos, Myanmar, and East Timor have seen their foreign exchange reserves depleted by soaring fuel costs, according to the Institute of Southeast Asian Studies (ISEAS)-Yusof Ishak Institute.

While public opinion in the region largely opposes the war, Okun believes a Democratic-controlled Congress is unlikely to compel President Trump to end the eight-month conflict. He anticipates that a shift in congressional power might lead to investigations and oversight hearings into the war, potentially impacting individuals like the Secretary of Defense, but not fundamentally altering the war's trajectory or its broader economic consequences for the region.

Beyond the war's impact, the region has also contended with the effects of US tariffs imposed under the Trump administration. These trade barriers have disrupted supply chains and increased costs for businesses in Asia, contributing to broader economic uncertainty.

Analysts point out that while the US Constitution grants Congress the power to declare war, President Trump has framed the actions in Iran as self-defense. This legal and political dynamic complicates any potential congressional efforts to force an end to the conflict.

Many in the Asia-Pacific are hoping that a new balance of power in Washington could lead to a recalibration of US foreign policy, potentially easing trade tensions and fostering a more stable global economic environment. However, the deep-seated nature of the current administration's policies suggests that such shifts may be slow to materialize.

The upcoming period will reveal whether the US midterm results translate into tangible policy adjustments that address the economic and geopolitical concerns of the Asia-Pacific nations, which remain vulnerable to global conflicts and trade disputes.
