Mizuho (<a href=\"\/stock\/8411\">8411<\/a>) has notably limited its interest-rate risk by maintaining a very short duration in its portfolio, avoiding long-term government bonds as <strong>10-year JGB yields<\/strong> reach levels not seen in three decades.<\/p>\n<h2>Pyongyang Slams U.S.-South Korea Military Exercises<\/h2>\n<p>The North Korean state news agency, <strong>KCNA<\/strong>, issued a stern warning on Tuesday, characterizing the annual <strong>Ulchi Freedom Shield<\/strong> drills as a &quot;dangerous provocation.&quot; A spokesperson for the Foreign Ministry claimed that military cooperation between the <strong>U.S.<\/strong>, <strong>South Korea<\/strong>, and <strong>Japan<\/strong> is rapidly evolving into a &quot;nuclear alliance,&quot; threatening regional stability.<\/p>\n<p>Pyongyang has vowed to respond to this &quot;new level of threat&quot; with a &quot;new level of deterrence,&quot; a phrase often used to signal impending ballistic missile tests or military displays. The <strong>11-day exercises<\/strong>, which began on <strong>August 17<\/strong>, involve approximately <strong>18,000 South Korean<\/strong> and <strong>28,500 U.S. troops<\/strong> and are designed to strengthen defensive readiness against North Korean nuclear and missile capabilities.<\/p>\n<h2>Market Implications and Regional Stability<\/h2>\n<p>The convergence of hawkish monetary policy shifts in Japan and heightened military tensions on the Korean Peninsula is creating a complex environment for investors. While the <strong>yen<\/strong> has seen some support from expectations of narrowing interest rate differentials with the <strong>U.S. Federal Reserve<\/strong>, geopolitical risks remain a primary source of volatility for Asian markets.<\/p>\n<p>Analysts note that North Korea often uses these joint drills as a pretext to ramp up its weapons testing to consolidate domestic support for leader <strong>Kim Jong Un<\/strong>. Simultaneously, the <strong>Bank of Japan&#39;s<\/strong> next move remains the focal point for global currency traders, as any acceleration in tightening could trigger a significant repatriation of Japanese capital from global bond markets.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways Mizuho Financial Group (8411) expects the Bank of Japan (BoJ) to accelerate interest rate
