While the <strong>Nikkei 225<\/strong> and <strong>Kospi<\/strong> reached fresh record highs driven by the AI boom, technology heavyweights in the US underperformed, dragging the <strong>Nasdaq Composite<\/strong> down <strong>1.32%<\/strong>.<\/p>\n<p>European markets are signaled for a weaker start, with <strong>Euro Stoxx 50<\/strong> and <strong>DAX futures<\/strong> both down <strong>0.4%<\/strong>. The sentiment reflects a cautious outlook as market participants await preliminary <strong>Purchasing Managers Index (PMI)<\/strong> data and monitor the fallout from political shifts in the United Kingdom.<\/p>\n<h2>Currency and Bond Market Volatility<\/h2>\n<p>The <strong>US Dollar<\/strong> gained ground as optimism over Iran was offset by a repricing of Fed interest rate paths under new Chair <strong>Kevin Warsh<\/strong>. The <strong>Euro<\/strong> fell to approximately <strong>1.1428<\/strong> after ECB President <strong>Christine Lagarde<\/strong> tempered expectations for aggressive rate hikes, stating there is no evidence of inflation &quot;de-anchoring.&quot;<\/p>\n<p>In the fixed-income market, <strong>Japanese Government Bond (JGB)<\/strong> yields continued their ascent. The <strong>10-year JGB yield<\/strong> climbed to <strong>2.680%<\/strong>, while the <strong>5-year yield<\/strong> reached <strong>1.920%<\/strong>, reflecting persistent pressure on the Bank of Japan to normalize monetary policy amid a historically weak yen.<\/p>\n<h2>Corporate and Geopolitical Developments<\/h2>\n<p><strong>SK Square (<a href=\"\/stock\/402340.KS\">402340.KS<\/a>)<\/strong> emerged as a primary beneficiary of the &quot;semiconductor supercycle,&quot; with its stock price approaching the <strong>2 million won<\/strong> milestone.

President <strong>Trump<\/strong> criticized the outgoing leader for failing to exploit <strong>North Sea oil<\/strong> and for initial hesitance in allowing US forces to use British bases in <strong>Cyprus<\/strong> for operations related to the Iran conflict. Despite the political transition, <strong>NESO<\/strong> reassured the public that the UK&#39;s electricity grid remains one of the most reliable globally, with sufficient reserves to avoid blackouts this winter.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways US-Iran peace negotiations in Switzerland show &quot;encouraging progress,&quot;
