FX & Rates

The US 10-year Treasury yield fell 6.0bp from 4.900% to 4.840%, moving closer to its 100-day average of 4.805%. The Korea 3-year yield also fell 4.5bp to close at 3.669%, below its 100-day average of 3.847%. The Dollar Index rose 0.19% to 101.61, while USD/JPY fell 0.26% to 158.09 yen per dollar.

Equities

The Nasdaq 100 closed at 26,629.81, down 1,807.36 points (6.36%). The KOSPI 200 also plunged 51.47 points (5.79%) to 837.78, leaving it 22.96% below its 100-day average. The Nikkei 225 fell 1.79% to close at 61,077.90, and Germany's DAX slipped 0.43% to 26,325.01. In contrast, the Hang Seng rose 3.67% to 24,796.98, the only major index to post a large gain.

Commodities & Crypto

WTI crude closed at 88.12 dollars per barrel on November 4, plunging 7.97 dollars (8.29%). Gold rose 132.60 dollars (3.37%) to 4,073.00 dollars, but remains 3.92% below its 100-day average of 4,239.37 dollars. Bitcoin stood at 75,871 dollars as of 7:00 a.m., down 5.72% from the previous day, weakening alongside equity markets.

News and Markets

With the Democrats taking both the Senate and the House, views emerged that the Iran war would be difficult to sustain, and this was reported as the direct backdrop to the sharp drop in WTI crude. News reports said New York stocks broadly rose, but data center-related shares fell on concerns about AI regulation, and Tesla also dropped sharply. The steep decline in the Nasdaq 100 in the market table is connected to the moves in these sectors. According to Korean news, the KOSPI decline also reflected worries about a pullback in AI investment, and the prevailing view is that tariff pressure is unlikely to ease quickly because of the presidential veto. The simultaneous fall in US yields and oil prices can be read alongside expectations that inflation pressure may ease.

What to Watch Today

The biggest variable is whether the Trump administration resumes further airstrikes on Iran. This decision is directly linked to oil prices and security in the Strait of Hormuz. Ahead of next week's US-mediated US-Russia-Ukraine peace talks in Abu Dhabi, it is also worth watching how the negotiating mood shifts after Russia's large-scale air attack. Whether the US 10-year Treasury yield stays near its 100-day average of 4.805% and whether USD/KRW holds around the 1,341 won level are also indicators to check. Another point to watch is how President Trump's signaled use of the veto, his tariff-related remarks and the debate over AI regulation affect semiconductor stocks in the Nasdaq 100 and KOSPI 200.
