Japan Market Opens: Semiconductor Stock Surge and Historic Weak Yen Lead Market 日本市場寄り付き: 半導体株高と歴史的円安が市場を牽引

Japan's market on July 22nd is off to a firm start, supported by a strong recovery in semiconductor-related stocks in the US market the previous day and the continuation of historically weak yen levels. The Nikkei average opened 217.08 yen higher at 60,6449.27 yen. Tensions in the Middle East are driving up crude oil prices, leading to "safe-haven dollar buying" which is further accelerating the yen's depreciation. While this is a tailwind for export-oriented companies, concerns about currency intervention are also rising. In the US market, following reports that Taiwan Semiconductor Manufacturing Company (TSMC) plans to raise its contract chip manufacturing prices by up to 10% in 2027, semiconductor stocks such as Micron Technology and Intel saw buying interest, pushing the Philadelphia Semiconductor Index (SOX) up by over 5%. Following this trend, semiconductor-related stocks are leading the overall market in Tokyo as well. A notable trend is the autonomous rebound from last week's excessive risk-off selling, with buying concentrated in specific stocks like Kioxia Holdings and Advantest. For related sectors, this appears to be a reaffirmation of the solid demand for AI, and medium-to-long term growth expectations are likely to be re-emphasized. A key point to watch going forward is the upcoming earnings reports from major US tech companies, as their results could significantly impact the performance of Japanese semiconductor-related stocks. The dollar-yen exchange rate has reached the 163 yen level, marking a new high not seen in approximately 39 and a half years, since December 1986. This rapid depreciation of the yen is primarily driven by rising oil prices due to heightened Middle East tensions and "safe-haven dollar buying." Furthermore, renewed expectations of interest rate hikes by the US within the year are also bolstering dollar demand. This historic level of yen weakness presents an opportunity for Japanese export companies to expand their profits, but simultaneously heightens concerns about potential currency intervention by the Japanese government. Market participants will be closely watching for strong verbal warnings against the weak yen from authorities or actual intervention. Middle East tensions remain high, with ongoing supply concerns fueling crude oil prices, such as the Houthi's declaration of a naval blockade on vessels related to Saudi Arabia. The US Department of Defense announced that the cost of the war in Iran has reached $37.5 billion so far [cite: "US war in Iran has cost $37.5 billion so far, Pentagon says - Reuters"]. Such geopolitical risks have the potential to increase global inflation concerns through crude oil prices and diminish expectations for US interest rate hikes. Today's Japanese market is expected to be supported by the surge in US semiconductor stocks and the historically weak yen. However, escalating Middle East tensions and the associated concerns about currency intervention will continue to be recognized as factors contributing to market volatility. Sources: kabutan.jp, yahoo.co.jp, minkabu.jp, toyokeizai.net本日7月22日の日本市場は、前日の米国市場での半導体関連株の力強い回復と、歴史的な円安水準が継続していることを背景に、堅調な滑り出しを見せています。日経平均株価は前日比217.08円高の6万6449.27円で寄り付きました。中東情勢の緊迫化による原油価格の高騰と、それに伴う「有事のドル買い」が円安をさらに加速させており、輸出関連企業にとっては追い風となる一方、為替介入への警戒感も高まっています。米国市場では、台湾積体電路製造（TSMC）が2027年に半導体の生産受託価格を最大10％引き上げると報じられたことを受け、マイクロン・テクノロジーやインテルなどの半導体関連株が買われ、フィラデルフィア半導体株指数（SOX指数）は5％を超える上昇を記録しました。この流れを受け、東京市場でも半導体関連株が全体相場を牽引しています。先週の過度なリスク回避売りに対する自律反発の動きが顕著であり、特にキオクシアホールディングスやアドバンテストなどの銘柄に買いが集中していると見られます。関連セクターにとっては、AI需要の底堅さが再確認された形となり、中長期的な成長期待が改めて意識されるでしょう。今後の観戦ポイントとしては、米国の主要テクノロジー企業の決算発表が控えており、その内容が日本市場の半導体関連株の動向に大きな影響を与える可能性があります. 為替市場ではドル円が163円台に到達し、1986年12月以来、約39年半ぶりの高値を更新しています。この急激な円安は、中東情勢の緊迫化による原油高と「有事のドル買い」が主な要因です。また、米国の年内利上げ観測の再燃もドル買いを後押ししています。この歴史的な円安水準は、日本の輸出企業にとっては収益拡大の好機となりますが、同時に日本政府による為替介入への警戒感が一段と高まっています。今後、当局からの強い円安牽制発言や、実際の介入の有無が市場の大きな注目点となるでしょう。中東情勢は依然として緊迫しており、フーシ派によるサウジアラビア関連船舶への海上封鎖宣言など、供給不安から原油高が続いています。米国防総省は、イランでの戦争費用がこれまでに375億ドルに達したと発表しており [cite: 「US war in Iran has cost $37.5 billion so far, Pentagon says - Reuters」], このような地政学的リスクは、原油価格を通じて世界のインフレ懸念を高め、米国の利上げ期待を後退させる可能性も秘めています。日本市場においては、原油価格の動向がエネルギー関連株や輸送コストに影響を与えるため、引き続き注意が必要です. 本日の日本市場は、米国市場の半導体株高と歴史的な円安が相場を支える形となるでしょう。しかし、中東情勢の緊迫化とそれに伴う為替介入への警戒感は、引き続き市場の変動要因として意識される見込みです。出典: kabutan.jp, yahoo.co.jp, minkabu.jp, toyokeizai.net
