However, some variation in economictrendshasbeenobservedacrosscountries,regions,andindustriesagainstabackdropofdisparitiesinthe benefitsofAI-relatedinvestment,theeffectsofrisingenergyprices,andotherfactors. Amidst ongoing disruptions in the Strait of Hormuz, companies and countries are making progress in adjusting their supply chains, including reviewing procurement sources and logistics routes and making use of inventories and alternative supply sources. Meanwhile, upward pressure on long-term interest rates is mounting, mainly in majordevelopedcountries,againstabackdropofresurgentinflationarypressuresandfiscalexpansion. Among developed countries, the U.S. economy has been supported by capital investment, centered on AI and data center-related investment, but rising energy prices have weighed on personal consumption and corporate activities. In theeuro zone, signsofa moderate recovery have been visible, supported by fiscalspending and other factors,butrisingenergyprocurementcostshaveweighedonhouseholdsandactivityinenergy-intensiveindustries suchassteelandchemicals.SignsofmoderaterecoveryhavealsobeenvisibleintheJapaneseeconomy,supported by rising wages, policy support, and other factors, but rising prices are slowing the recovery of personal consumption. In China, the economy issupported by exports, butweaknesspersistsin domestic demand againsta backdrop of sluggishness in the real estate market and other factors. In some countries and regions of Asia, exports of semiconductors,electroniccomponents,electricalequipment,andrelatedproductshaveremainedrobust,supported by an expansion of AI and data center-related investment. However, in countries where the benefits of AI-related demand have been limited and there is high dependence on energy imports, rising import prices and other factors haveputdownwardpressureontheireconomies. Ininternationalcommoditymarkets,energypricesremainhighamiddisruptionstoshippingthroughtheStraitof Hormuz and other factors.

Future risks include prolonged or renewed tensions in the Middle East and disruptions in the Strait of Hormuz, prolonged inflation due to persistent high energy and raw material prices, monetary tightening and higher market interest rates as a result of these developments, and growing government debt and fiscal burdens associated with fiscal expansion in various countries. In addition, continued vigilance is necessary regarding adjustments in financial markets driven by a slowdown in AI-related investment and reassessments of earnings expectations, renewedtradefriction,andgeopoliticalrisksinNortheastAsia,SoutheastAsia,Africa,andotherregions. 6
