霍尔木兹海峡封锁造成了几代人以来最深的能源扰动，原油产量减少约900万桶/日，折算约143万立方米/日。燃料、肥料、氦和塑胶相关成本上升已开始推高全球通膨。彭博预测2026年全球成长降至2.9%，低于2025年的3.4%，Kristalina Georgieva也表示原本可提高的成长预测将被下修。债务成为主导约束：全球债务高达348兆美元，发展中国家有34亿人现在支付的债务服务支出高于医疗或教育支出。
次危机以后并未转化为资产负债表修复，赤字持续累积。美国和英国财政承受压力，巴基斯坦与肯亚更为吃紧；企业部门在疫情后及AI基础设施繁荣期也显著加杠杆。美国虽可较低成本借款，但并非最易受害，其他国家面对融资条件更紧。随著政治分裂、关税上升、援助削减与G20凝聚力下降，缺乏明确的多边领导者。IMF虽有1640亿美元已发放贷款与191个成员、1兆美元总授信额，但批评者认为监测能力走弱。若危机再度升温，中央银行可能再次配合紧急财政支出，但将付出更高债务服务成本与更严苛的未来融资，尤其在美国公共债约32兆美元、年度利息接近1兆美元时。
Over recent decades, the global system recovered from the Great Recession and the pandemic through coordinated central-bank stimulus and synchronized fiscal actions, but the Iran war reveals a very different environment now. Even after a two-week ceasefire and Iran’s pledge to reopen the Strait of Hormuz, the truce is still seen as fragile. At the IMF and World Bank spring meetings, policymakers are preparing for weaker growth, strained budgets, stressed electricity and food markets, and higher volatility, with the core question being how to absorb another synchronized external shock.

The Strait of Hormuz closure caused the most severe energy disruption in generations, with crude output down about 9 million barrels per day, approximately 1.43 million cubic meters per day. Higher fuel, fertilizer, helium, and plastics-related costs are already pushing up global inflation. Bloomberg projects global growth for 2026 at 2.9%, down from 3.4% in 2025, and Kristalina Georgieva says earlier upward revisions are likely to be reversed. Debt is the key constraint: global debt is 348 trillion USD, and 3.4 billion people in developing countries now spend more on debt service than on health or education.
The post-crisis lesson has not translated into balance-sheet repair, so deficits keep building. Governments in the United States and the United Kingdom are under pressure, with Pakistan and Kenya under even tighter stress, while corporate borrowers have become more leveraged after the pandemic and the AI infrastructure boom. The United States can borrow at lower cost but is not the only exposed economy; many others face tighter financing. With political fragmentation, tariff hikes, aid cuts, and weakened G20 cohesion, there is no clear multilateral leader. The IMF still has 164 billion USD in outstanding loans, 191 members, and total lending capacity of 1 trillion USD, yet critics say surveillance has weakened. If the crisis deepens again, central banks may again support emergency fiscal spending, but at the cost of higher debt-service burdens and harder future financing, especially as U.S. public debt is around 32 trillion USD with annual interest approaching 1 trillion USD.
