Trump-Zelenskyy Meeting, NATO Tensions Shape Defense, Oil Trades

President Donald Trump will meet Ukrainian President Volodymyr Zelenskyy at a NATO summit in Turkey on Wednesday. The session arrives with the White House consumed by the Iran war and a global energy crisis from the Strait of Hormuz closure. European allies, already rattled by Trump's demands for higher defense spending and his push to acquire Greenland, face pressure to step up.

Trump arrives in Turkey on Tuesday for a bilateral meeting with President Recep Tayyip Erdogan, White House spokesperson Anna Kelly said.

The U.S. has said it will withdraw 5,000 troops from Europe and slash the military assets Washington would provide in a crisis. Ambassador to NATO Matt Whitaker told reporters Trump expects allies to reach defense spending of 5% of GDP "as soon as possible."

The defense spending target is not new. The urgency is. European nations that declined to let the U.S. use bases for early strikes against Iran now face a president who sees the alliance as a one-way street. The Iran war, launched on Feb. 28 without allied consultation, sparked the Hormuz closure that halted oil and gas shipments. U.S. allies grappled with the fallout without being asked about the decision.

The summit creates binary scenarios across a few asset classes.

Defense stocks benefit from a firm commitment to higher spending. A unified statement on the 5% target would validate the longer-term procurement cycle for European contractors. A public fight over burden-sharing would reinforce the perception that the alliance is fraying, hitting sentiment across the sector. Trump's Saturday phone call with Russian President Vladimir Putin, confirmed by Kremlin aide Yuri Ushakov, adds another layer. A Ukraine ceasefire framework would reduce the defense urgency but also remove a key driver for higher European budget allocations. The net effect is ambiguous.

Oil prices depend on Hormuz. Any sign of a coordinated effort to reopen the strait would send crude sharply lower. Continued stalemate keeps the risk premium in place. The summit could produce new commitments to secure shipping lanes. The White House has been frustrated by European reluctance to contribute militarily to that effort, three U.S. officials told reporters.

European equities face a headwind from transatlantic friction. A public clash over Greenland or base access would reinforce the deglobalization trade. A smooth summit would remove a short-term risk.

Confirming factors. A unified NATO statement endorsing the 5% spending target and a concrete plan to reopen Hormuz would lift defense stocks and pressure oil. The currency pair most sensitive is EUR/USD, which would rally on reduced geopolitical risk.

Invalidating factors. A public confrontation over Greenland or base access, or a failure to produce a joint communiqué, would hit European equities and keep the oil premium elevated. Trump's Tuesday meeting with Erdogan could preview the tone. Erdogan has leverage as a NATO member that was consulted on the Iran war.

Ukraine has increasingly struck deep inside Russia with drones and missiles. A U.S. official told reporters the administration views the conflict as one where neither side is making much progress. Trump will press Zelenskyy for a path to end the war, the official said. The outcome of those talks will shape the defense narrative.

The summit's outcome will influence positioning for weeks. A cohesive statement on defense spending and energy security would confirm the alliance is still functional. A fractured summit would reinforce the risk-off tone for European assets and keep the oil risk premium elevated.

Trump's Tuesday meeting with Erdogan offers the first real signal of the week's direction.
