Asia Market Wrap 21 September: The Kospi Reclaims 7,000 With Japan Shut and Oil Under 101
Asia opened the week higher without Japan. South Korea’s Kospi rose 1.65 percent to close at 7,007.72, back above the 7,000 line after ending last week at 6,894.23, the Hang Seng added 1.18 percent and Taiwan’s Taiex 1.14 percent, and no index on the board fell, with Japanese markets closed for a public holiday, per the network’s world markets blog, so the Nikkei 225 and Topix sat out the session. The week’s axis is set in Washington and Beijing: a summit between President Donald Trump and President Xi Jinping covering tariffs, critical minerals and artificial intelligence, per the same blog. Brent crude traded 3.17 percent lower at 100.58 dollars a barrel at our 10:41 GMT capture.
Seoul leads a board that rose everywhere it opened
The advance was broad and Korean led. The Kospi’s 1.65 percent rise extended Friday’s 2.66 percent jump, the session of the Bank of Japan’s rise at the close of the Fed week, and both Chinese boards climbed, the Shanghai Composite 0.97 percent to 3,949.91 and the Shenzhen Component 0.65 percent to 13,730.02, with Hong Kong up 1.18 percent. India’s Nifty 50 added 0.29 percent and Australia’s S&P/ASX 200 closed 0.01 percent higher, the board’s smallest move, while Singapore’s Straits Times rose 0.34 percent. The summit gives the region its frame: Treasury Secretary Scott Bessent met Chinese Vice Premier He Lifeng ahead of the visit, per the network’s blog, and LPL Financial’s chief economist Jeffrey Roach tied the strands together in a note the blog carried: “The same geopolitical conflict inflating energy prices is also what’s keeping the [Federal Reserve] hawkish and what’s squeezing Chinese refiners.”
Oil slides on flows that refuse to break
The standing block carries the other story. Brent traded 3.17 percent lower at 100.58 dollars a barrel and WTI 3.10 percent lower at 97.19 dollars, under the 100 dollar line at our capture, after JPMorgan analysts wrote in a note the network cited that “Middle East oil flows remain surprisingly strong despite the disruption to Saudi Arabia’s East-West pipeline”, putting total flows at an average of 17.1 million barrels a day over the past 10 days, 6.1 million below the 2025 average, even after Iran backed Houthi missile and drone attacks on Saudi Arabia on Saturday, per the network’s oil report. President Trump told Fox News he is in a “deciding mode” and that “very big things” are coming, per the same report. Gold eased 0.84 percent from Friday’s settlement to 4,387.70 dollars an ounce and silver 0.71 percent to 66.67, while the yen, with Tokyo’s desks away, weakened 0.21 percent to 157.19 per dollar.

Why it matters: the region’s first Monday after the Fed and Bank of Japan decisions produced a rally, not a wobble, on our reading: Seoul cleared a round number, both Chinese boards rose into a summit whose agenda, tariffs, critical minerals and artificial intelligence, prices directly into their exporters, and the day’s only restraint came from the markets that were not open. The oil column is doing the macro work, on our reading: crude falling on resilient flows loosens the same variable the LPL note says the Fed has conditioned its inflation outlook on, which is why an equity board this green and a Brent print near 100 dollars are one story, not two.
Outlook: our Middle East wrap follows this afternoon with the Gulf boards’ second session on the region’s new policy rates, and the Bank of Japan’s rise to about 1.25 percent takes effect on Thursday, per its Friday statement, the same day Tokyo returns to its desks, with Tuesday and Wednesday also market holidays in Japan per the exchange’s calendar. The Trump and Xi summit sits over the week, alongside the United Nations General Assembly in New York, and for this board the test is whether Seoul holds 7,000 with the two heaviest policy variables, tariffs and oil, both in motion.
