While this figure was slightly better than the <strong>3.6% drop<\/strong> anticipated by economists, it highlights a persistent trend of stagnant private consumption. <em>Analysts suggest that while nominal wages are rising, they have yet to consistently outpace the rising cost of living.<\/em><\/p>\n<p>Inflation remains a primary headwind, with the consumer price index (CPI) holding at <strong>2.6%<\/strong> in August, well above the <strong>Bank of Japan\u2019s<\/strong> 2% stability target. This environment has forced households to become increasingly cost-conscious, particularly regarding discretionary purchases. <em>The weak yen has further exacerbated the issue by keeping the cost of imported goods and energy elevated.<\/em><\/p>\n<h2>Nvidia Embraces &quot;Co-opetition&quot; with d-Matrix Investment<\/h2>\n<p>In a strategic shift toward a more modular AI factory architecture, <strong><a href=\"https:\/\/stockmarketwatch.com\/stock\/NVDA\" data-internallinksmanager029f6b8e52c=\"15\" title=\"stock: NVDA\">Nvidia<\/a> (<a href=\"\/stock\/NVDA\">NVDA<\/a>)<\/strong> has announced a partnership with chip startup <strong>d-Matrix<\/strong>.
