Yemen's Presidential Leadership Council has annulled its defense pact with the UAE, ordered Emirati forces to withdraw within 24 hours and declared a 90-day emergency with a 72-hour closure of ports and airspace. This escalates tensions within the Saudi-led coalition, complicates the anti-Houthi war and could reshape Gulf security and OPEC coordination for decades.
Verdict: Evidence from state and international media shows Yemen cancelled its defense pact with the UAE, ordered Emirati troops out within 24 hours and imposed emergency measures including a 72-hour port and air closure (Xinhua, 2025-12-30; Anadolu, 2025-12-30; Reuters, 2025-12-30). ([english.news.cn](https://english.news.cn/20251230/4e764a33510043bf92afabdec02222e4/c.html?utm_source=openai)) This rupture raises near-term risks of intra-coalition clashes and shipping disruption. Over 3-10 years, shared interests in countering the Houthis and stabilising oil markets still favour an eventual renegotiated security framework over a lasting break.
Rapid regional diplomacy de-escalates the Yemen-UAE dispute and clarifies roles within the coalition. Emirati forces withdraw in an orderly fashion or are re-mandated under a new framework, while the Southern Transitional Council accepts constraints. Shipping lanes remain open and a modest roadmap toward a political settlement with the Houthis re-emerges.
The split triggers months of tense stand-offs, sporadic clashes and economic disruption but is gradually managed through Saudi-led mediation. Yemen's Presidential Leadership Council survives, though fragmented, and a modified security architecture emerges with clearer Saudi control and a narrower Emirati footprint. OPEC coordination suffers short-term frictions but adapts as both states prioritize oil revenues.
Confrontations between UAE-backed Southern Transitional Council forces and Saudi-backed units intensify into open conflict in southern and eastern Yemen. Houthi forces exploit divisions to gain territory and threaten shipping lanes and cross-border infrastructure. Saudi-UAE relations deteriorate, weakening OPEC's ability to manage prices and drawing in more external actors.
A dramatic political shift in a key capital or an external shock, such as a major attack or wider regional war, radically reshapes priorities. Yemen becomes an arena for a broader Saudi-UAE-Iran competition with fluid alliances and shifting front lines. Alternatively, an unexpected breakthrough, like a comprehensive Gulf security pact, rapidly de-escalates the crisis but depends on leadership changes.
Developments: Through 2026, Saudi-backed and UAE-backed forces jostle for control in southern and eastern Yemen while the Houthis watch for openings. Emergency measures on ports and airspace are relaxed but not fully unwound, and navies increase patrols near Bab el-Mandeb and Mukalla (Reuters, 2025-12-30).

Risks: A miscalculation, errant strike or proxy escalation could damage tankers or port infrastructure, triggering abrupt shipping diversions. Houthi or other armed groups may exploit coalition divisions to launch attacks deeper into Saudi or Emirati territory. Humanitarian conditions in Yemen could worsen if blockades and clashes restrict food, fuel and aid flows.
Outlook: The crisis remains dangerous but mostly contained geographically. Markets adapt to a higher but manageable level of geopolitical risk. Diplomacy focuses on crisis-management more than final conflict resolution.
Developments: By 2027, a de facto division of roles is likely, with Saudi forces and aligned Yemeni units dominant in key eastern provinces and maritime chokepoints. The UAE maintains influence through the Southern Transitional Council and limited forces, even if formal deployments shrink. Back-channel talks work toward updated security arrangements linking Yemen, Red Sea security and oil-market stability.
Risks: If no clear political framework emerges, local commanders may act autonomously, increasing the chance of renewed large-scale clashes. Rival Gulf information campaigns could inflame domestic opinion and reduce room for compromise. External powers may deepen involvement, complicating already-fragile negotiations.
Outlook: Some rudimentary rules of the game stabilise the front lines. Yemen remains fragmented but major regional players avoid direct confrontation. The conflict drags on with lower intensity but persistent human and economic costs.
Developments: Around 2028, maritime security arrangements around Bab el-Mandeb and the Arabian Sea are likely anchored in broader Gulf understandings, possibly with international naval support. OPEC and OPEC+ adapt governance to manage Saudi-UAE frictions while preserving a functioning production-coordination mechanism. Yemen's internal map remains patchwork, but front lines stabilise and some reconstruction projects begin in safer areas.
Risks: A sudden oil-market shock could re-politicise production quotas and spill back into security cooperation. If Yemen's peace track stalls entirely, war economies and armed groups may deepen their hold on territory and smuggling routes. Regional rivalries involving Iran, Israel or Turkey could intersect Yemen's conflict in destabilising ways.
Outlook: Security around key shipping lanes improves relative to the crisis peak. Political progress inside Yemen is halting and partial. Global markets still treat the region as a structural risk, not a resolved issue.
Developments: By 2030, international fatigue and reconstruction needs likely push parties toward more structured talks on Yemen's political future, including southern autonomy questions. A hybrid security architecture mixes Yemeni forces with limited, more transparently mandated external support. Donors and IFIs begin funding infrastructure and governance projects tied to ceasefire benchmarks.
Risks: Spoilers in all camps may sabotage negotiations if they perceive threats to their power or patronage networks. Economic shocks, such as prolonged low oil prices, could reduce resources for reconstruction and buy-offs. Failure to integrate local armed groups into national structures risks relapse into fragmented conflict.
Outlook: A negotiated framework becomes plausible but remains reversible. Economic incentives and war fatigue support compromise, yet mistrust runs deep. International engagement is critical to keep parties committed.
Developments: By 2035, the Yemen crisis will have contributed to a more formalised Gulf security order in which Saudi Arabia plays the central organising role. The UAE retains selective influence but pursues a more limited, interest-specific posture in Yemen and the Red Sea. Regional institutions and ad-hoc coalitions coordinate naval patrols, missile defence and crisis responses more predictably.
Risks: Institutionalised security arrangements could entrench spheres of influence and freeze unresolved grievances inside Yemen. New technologies, including drones and cyber tools, may empower non-state actors to threaten infrastructure despite stronger state coordination. Great-power rivalry over bases and access rights may inject volatility into otherwise stable arrangements.
Outlook: The immediate rupture between Yemen and the UAE is absorbed into a broader regional evolution. Security cooperation is more structured but not fully inclusive or just. Stability improves for trade but remains fragile for local populations.
Developments: By 2045, Gulf and Red Sea security will likely be embedded in wider Middle East and African frameworks, possibly with stronger African coastal-state roles. Yemen, if stabilised, could function as a secondary but strategic participant in these arrangements. Energy transitions reduce but do not eliminate the importance of shipping lanes and remaining hydrocarbon exports.
Risks: Climate-driven displacement and resource stress may generate new conflicts that intersect legacy fault lines from the Yemen war. If governance in Yemen stays weak, militias and criminal networks may use its coasts as hubs despite regional patrols. Reduced oil revenues may constrain states' ability to buy stability at home and abroad.
Outlook: Regional structures become denser and more multilateral. Old conflicts fade but leave institutional and social scars. Security and prosperity depend increasingly on domestic reforms as well as cross-border cooperation.
Developments: By 2075, the specific Yemen-UAE rupture is likely remembered mainly by specialists, but its role in nudging Gulf states toward more formal security arrangements persists. Yemen's long-term trajectory, from fragile state to either functional polity or chronic crisis zone, will shape how this episode is judged. Maritime trade routes remain critical, though energy mixes and great-power constellations have changed.
Risks: If Yemen fails to consolidate stable governance, periodic flare-ups could continue to threaten coastal security and humanitarian conditions. Power shifts among Gulf states may reopen old grievances embedded in today's decisions. New technologies or climate disruptions could create unforeseen vulnerabilities at sea and in coastal megacities.
Outlook: The current crisis becomes one chapter in a longer story of Gulf state-building and regional integration. Its ultimate legacy depends on how effectively states turn ad-hoc reactions into durable, inclusive institutions. Neglecting Yemen's internal recovery would keep the region exposed to recurring shocks.
