Asian Markets Surge on August 5 Amid AI Earnings and Hopes for Strait of Hormuz Reopening
8/5/2026, 4:06:59 PM
Core Event – August 5 Rally
- On August 5 Asian equity indices jumped sharply. Japan’s Nikkei rose about 3 % to 66,300, South Korea’s Kospi surged 4.3 % to 6,598, and the MSCI Asia-Pacific index outside Japan climbed 2.3 %. Chinese blue-chip CSI 300 added 1.5 %. The rally coincided with record-high closes for U.S. benchmarks, including the S&P 500 (+1.8 %) and the Dow Jones Industrial Average (+1.7 %).
Background & Context
- The surge followed a week of strong U.S. corporate earnings that lifted Wall Street to new highs. At the same time, oil prices fell as reports suggested progress toward reopening the Strait of Hormuz, a key chokepoint for global oil shipments. Lower oil prices eased inflation concerns and pushed 10-year U.S. Treasury yields down from a recent high of 4.747 % to around 4.60 %.
Data & Statistics
- Oil: Brent crude fell between $78 and $85 per barrel across reports (e.g., $78.27, $79.36, $84.92). U.S. WTI dropped to $75-$75.09.
- Bond yields: 10-year Treasury yields reported at 4.603 % (Reuters Aug 5), 4.62 % (AP Aug 4), and 4.68 % (Euronews Aug 4).
- Fed expectations: Probability of a September rate hike fell from 67 % to 57 % (Reuters Aug 5).
- AI-related stocks: SoftBank +10 %, Tokyo Electron +3.64 %, Advantest +7 %, Kioxia +6.34 %, SK Hynix +6.9 %, Samsung +4 %.
Official Statements & Responses
- John Oh, energy economist at CBA, estimated Strait-of-Hormuz traffic had recovered to 40-45 % of pre-war levels and that 50-60 % would be enough to create oversupply conditions.
- Scott Bessent, U.S. Treasury Secretary, expressed confidence that Bank of Japan Governor Kazuo Ueda would “do what is best” for Japan’s economy.
- Jeff Schmid, President of the Federal Reserve Bank of Kansas City, called for tighter monetary policy to return inflation to the 2 % target.
Why It Matters
- Lower oil prices and falling Treasury yields reduced inflation pressures, prompting markets to downgrade expectations for another Fed rate increase in September.
- Strong earnings from AI-focused firms reinforced investor optimism about the sector’s growth, despite concerns about high capital expenditures for compute power.
Conflicting Reports & Gaps
- Brent crude price is reported at $78.27, $79.36, $84.92, and $84.75 for the same period, indicating a lack of consensus on the exact level.
- While several sources cite a decline in oil prices as a driver of the rally, the precise timing and certainty of a formal Strait-of-Hormuz reopening remain unverified.
