Bank of Japan (<a href=\"\/stock\/8301\">8301<\/a>) Governor <strong>Kazuo Ueda<\/strong> reported that while the global economy remains resilient, the rapid expansion of <strong>AI-related investment<\/strong> is creating new upward pressure on prices. Japanese Finance Minister <strong>Satsuki Katayama<\/strong> specifically pointed to the &quot;massive&quot; debt issuance by U.S. technology giants\u2014such as <a href=\"https:\/\/stockmarketwatch.com\/stock\/MSFT\" data-internallinksmanager029f6b8e52c=\"18\" title=\"Stock: MSFT\">Microsoft<\/a> (<a href=\"\/stock\/MSFT\">MSFT<\/a>) and <a href=\"https:\/\/stockmarketwatch.com\/stock\/NVDA\" data-internallinksmanager029f6b8e52c=\"15\" title=\"stock: NVDA\">Nvidia<\/a> (<a href=\"\/stock\/NVDA\">NVDA<\/a>)\u2014to fund AI infrastructure as a factor driving up bond yields.<\/p>\n<p>The <em>synchronous tightening<\/em> of monetary policy across major economies was a central theme, with the <strong>IMF<\/strong> noting that AI demand has helped mitigate the economic pain of Middle East conflicts. However, the inflationary side effects of this tech boom may force central banks, including the <strong>BOJ<\/strong>, to maintain or accelerate their rate-hike cycles. Governor Ueda\u2019s insights from the summit are expected to influence the <strong>BOJ\u2019s<\/strong> upcoming quarterly growth and inflation projections due later this month.<\/p>\n<h2>Japan\u2019s Strategic Shift Toward Nuclear Submarines<\/h2>\n<p>On the domestic front, <strong>Prime Minister Sanae Takaichi<\/strong> informed parliament that Japan is moving toward a &quot;concrete and realistic&quot; evaluation of <strong>nuclear-powered submarines<\/strong>. This potential shift in defense policy aims to bolster intelligence and surveillance capabilities in the Pacific, where Tokyo faces increasing pressure from Chinese naval activities. Unlike conventional vessels, nuclear submarines can remain submerged for months and travel at significantly higher speeds, offering a critical advantage in long-range deterrence.<\/p>\n<p>The proposal marks a significant departure from Japan\u2019s post-war &quot;exclusive defense&quot; posture and its <strong>Three Non-Nuclear Principles<\/strong>. While the government has not yet made a final acquisition decision, officials are considering including a formal &quot;research and study&quot; plan in the revised <strong>National Security Strategy<\/strong> documents slated for year-end. Proponents, including Defense Minister <strong>Shinjiro Koizumi<\/strong>, argue that the evolving security environment in East Asia necessitates exploring all options, including advanced underwater propulsion, to ensure national safety.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways G20 finance leaders identified artificial intelligence (AI) and Middle East instability as
