intervened in the foreign exchange market during New York trading on Friday, according to government sources. The yen experienced an abrupt surge, moving from the <strong>162 range to the mid-157s against the dollar<\/strong> in less than an hour. This move follows weeks of speculation as the currency&#39;s weakness threatened to exacerbate living costs already pressured by an energy shock linked to Middle East tensions.<\/p>\n<p>Market analysts estimate the intervention scale at <strong>6 to 7 trillion yen<\/strong>, marking the first such foray in three months. Finance Minister Satsuki Katayama declined to confirm the specific action but stated that authorities are &quot;acting with vigilance.&quot; The intervention was reportedly coordinated with rate checks by U.S. authorities, signaling a potential shift in international tolerance for the yen&#39;s extreme depreciation.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"South_Koreas_Chip_Boom_Drives_Record_Trade_Surplus\"><\/span>South Korea&#39;s Chip Boom Drives Record Trade Surplus<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>South Korea\u2019s export-led economy continues to benefit from the global artificial intelligence boom. Outbound shipments of <strong>semiconductors shot up 179% to $41 billion in July<\/strong>, topping the $40 billion mark for the second consecutive month. This surge resulted in a <strong>monthly trade surplus of $30.32 billion<\/strong>, as demand for high-bandwidth memory (HBM) and AI server SSDs remains insatiable.<\/p>\n<p>Major players like Samsung Electronics (<a href=\"\/stock\/005930\">005930<\/a>) and SK Hynix (<a href=\"\/stock\/000660\">000660<\/a>) are the primary beneficiaries of this &quot;semiconductor supercycle.&quot; While 19 of the 20 major export categories posted gains\u2014including a <strong>7% rise in automobile exports<\/strong>\u2014Industry Minister Kim Jung-kwan warned of growing headwinds from global protectionism and geopolitical uncertainty in the Middle East.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"BOJ_Signals_Hawkish_Shift_Despite_Rate_Hold\"><\/span>BOJ Signals Hawkish Shift Despite Rate Hold<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The Bank of Japan (<a href=\"\/stock\/8301\">8301<\/a>) maintained its benchmark overnight call rate at <strong>1.0%<\/strong> in a split 8-1 vote. However, the accompanying quarterly outlook was notably more hawkish than previous reports. Governor Kazuo Ueda emphasized that &quot;underlying inflation is approaching our 2 percent target,&quot; and warned that the bank must scrutinize upside price risks more than ever.<\/p>\n<p>The central bank is closely monitoring the fallout from a <strong>magnitude 7.1 earthquake<\/strong> that recently struck Kumamoto, a critical hub for Toyota Motor (<a href=\"\/stock\/TM\">TM<\/a>) and Taiwan Semiconductor Manufacturing Co. (<a href=\"\/stock\/TSM\">TSM<\/a>). While thousands remain in shelters, businesses are moving to restart operations.

The strike damaged the vessel&#39;s engine compartment, leaving it &quot;not under command.&quot; While no injuries or environmental damage were reported, the incident has heightened fears regarding the safety of the <strong>Strait of Hormuz<\/strong>.<\/p>\n<p>This attack follows a period of escalating military tensions between the U.S. and Iran. Shipping data already shows a sharp decline in the number of tankers transiting the region. Market participants are watching for any shifts in threat levels that could further disrupt global oil and gas shipments, potentially driving energy prices higher and complicating central bank efforts to tame inflation.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Technical_Outlook_NZDUSD_Eyes_06000\"><\/span>Technical Outlook: NZD\/USD Eyes 0.6000<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In the currency markets, the <strong>NZD\/USD pair<\/strong> is showing bullish momentum after breaking above its 200-day Simple Moving Average (SMA). Traders are now eyeing the <strong>psychological 0.6000 level<\/strong> as the next major resistance. The breakout suggests a constructive shift in market structure, supported by a softer U.S. dollar and improving risk appetite. If the pair maintains its position above the 0.5850 support level, analysts expect a challenge of the May highs in the coming sessions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key
