Japan\u2019s top currency diplomat, <strong>Atsushi Mimura<\/strong>, described the move as a potential &quot;culmination&quot; of the U.S.-Japan currency partnership, while the <strong>Ministry of Finance (MOF)<\/strong> confirmed plans to utilize the Federal Reserve\u2019s <strong>FIMA repo facility<\/strong> for future liquidity needs.<\/p>\n<p>The <strong>USD\/JPY pair fell 0.5% to 156.64<\/strong>, extending a decline that has rattled Japanese exporters. Consequently, major Japanese stocks faced significant headwinds; <strong>Toyota Motor (<a href=\"\/stock\/TM\">TM<\/a>)<\/strong> shares slipped <strong>4.5%<\/strong>, while <strong>SoftBank Group (<a href=\"\/stock\/SFTBY\">SFTBY<\/a>)<\/strong> fell <strong>3%<\/strong> as the stronger yen and broader tech weakness weighed on sentiment.<\/p>\n<h2>Trump\u2019s Iran Diplomacy Triggers Oil Collapse<\/h2>\n<p>Global energy markets experienced a massive shock after Donald Trump revealed he had <strong>called off planned military strikes against Iran<\/strong> at the request of allies, including Saudi Arabia. Trump announced that <strong>fresh talks with Tehran<\/strong> are scheduled to begin this Monday, aiming for a deal to secure the <strong>Strait of Hormuz<\/strong>.<\/p>\n<p><strong>Brent crude for October delivery plummeted as much as 7.3%<\/strong>, while <strong>WTI fell below $81<\/strong>, erasing a significant portion of July&#39;s gains. Despite the diplomatic relief, shipping risks remain a concern after the <strong>UKMTO<\/strong> reported an explosion near a tanker off the coast of Oman on Sunday.<\/p>\n<h2>Asia-Pacific Markets Retreat Amid Volatility<\/h2>\n<p>Despite the reduction in geopolitical tensions regarding Iran, Asia-Pacific equity markets opened sharply lower. Investors are balancing the &quot;geopolitical relief&quot; against <strong>lingering tech sector weakness<\/strong> and the implications of higher Japanese interest rates. <strong>Short-dated JGBs fell<\/strong> as expectations grow for a <strong>Bank of Japan (BOJ)<\/strong> rate hike.<\/p>\n<p>South Korea\u2019s <strong>KOSPI<\/strong> was the region&#39;s worst performer, <strong>diving 5%<\/strong> in early trade. In Japan, the <strong>S&amp;P Global Manufacturing PMI<\/strong> for July was finalized at <strong>54.5<\/strong>, slightly lower than the previous reading of 54.7, suggesting a marginal cooling in industrial expansion.<\/p>\n<h2>AI Breakthroughs and Commodity Shifts<\/h2>\n<p>In the technology sector, reports surfaced that <strong>OpenAI\u2019s<\/strong> upcoming <strong>Astra<\/strong> model family has successfully cracked <strong>10 challenging problems<\/strong> in advanced mathematics and computer science. This development is expected to intensify the &quot;AI arms race&quot; even as broader tech stocks face a valuation correction.<\/p>\n<p>In commodities, <strong>Gold rose 0.6% to $4,070<\/strong>, benefiting from a &quot;first monthly increase since February.&quot; While oil prices fell on supply hopes, gold investors are betting that a breakthrough in Iran talks could eventually <strong>ease energy-driven inflation<\/strong>, potentially altering the Federal Reserve&#39;s long-term interest rate trajectory.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways U.S. and Japan
