Hey everyone, Hirokichi here.
Tokyo stocks closed higher on August 17, 2026, with the Nikkei 225 up 484.45 points (+0.71%) at 69,198.25, extending its winning streak to five straight sessions. The TOPIX (Tokyo Stock Price Index), on the other hand, slipped 9.10 points to 4,188.10, so the two benchmarks moved in opposite directions today. Looking ahead to tonight’s US session, investors will be watching housing-related data ahead of this week’s FOMC (Federal Open Market Committee, the Fed’s policy-setting meeting) minutes.
Nikkei Up for a Fifth Day, TOPIX Slips – A Split Session
The Nikkei 225 opened at 68,882.06 today. By the mid-day break, it was up just 7.64 points from Friday’s close, at 68,721.44 (according to Kabutan). The index then extended its gains through the afternoon session, closing at 69,198.25, up 484.45 points (+0.71%) from the previous close (according to Kyodo News). That’s a fifth consecutive day of gains.
The TOPIX, meanwhile, closed at 4,188.10, down 9.10 points from the previous day. The Nikkei tends to be more sensitive to the moves of a handful of high-priced stocks, while the TOPIX reflects the total market capitalization of a much broader set of companies. Today’s divergence between the two suggests more stocks fell than rose. In fact, at the mid-day break, 675 issues were up versus 818 down (according to Kabutan).
Chip and AI Names Lead the Charge, Uniqlo’s Parent a Drag
The rally was led by semiconductor and AI-related names. According to Kabutan’s mid-day contribution rankings, Advantest added 173.78 points to the Nikkei on its own, followed by Tokyo Electron (+77.44) and Kioxia Holdings (+71.80). Nintendo and Mitsubishi UFJ Financial Group also held up well.
On the downside, Fast Retailing (parent of Uniqlo) was the single biggest drag, subtracting 61.95 points. Only 7 of the market’s 33 sectors were higher at the mid-day break, led by nonferrous metals, marine transport, construction, and oil and coal products (according to Kabutan). Even with more decliners than advancers, the heavy buying in a few large chip names was enough to carry the Nikkei to a strong close.
Yen Holds Near 159, With 160 as This Week’s Key Level
USD/JPY traded in the upper-158-to-159 range today, sitting around 159.20-159.22 this morning – roughly unchanged from Friday (according to Nikkei). Gaitame.com’s weekly outlook (August 17-21) points to a range of 158.20-160.80, with 160 seen as a key psychological level. Expectations for a Bank of Japan rate hike in September remain a factor to watch as well.
Tonight’s US Market Outlook: Housing Data and FOMC Minutes on the Radar
At Friday’s close (August 14), the S&P 500 finished at 7,785.76 (-0.17%), the Dow Jones Industrial Average at 53,732.41 (-0.20%), and the Nasdaq Composite at 26,729.16 (-0.28%) – all three indexes pulled back slightly. On a weekly basis, though, the S&P 500 gained 0.47% and the Nasdaq 100 gained 1.46%.
The backdrop: July retail sales fell 0.6% month-over-month (versus a forecast of +0.1%), a sharp miss. The University of Michigan’s preliminary August consumer sentiment index also dropped to 51.0 from July’s 55.2. Meanwhile, July’s Consumer Price Index (CPI, a key measure of inflation) stayed elevated at 3.4% year-over-year. It’s an uncomfortable combination – prices aren’t coming down, and consumers are pulling back at the same time.
On the policy front, the Fed (Federal Reserve, the US central bank) is currently chaired by Kevin Warsh. At the July 28-29 FOMC meeting, the Fed held its target rate at 3.50-3.75%, and markets currently see roughly a two-thirds chance of another hold in September. This week’s calendar includes the New York Fed’s manufacturing index and the NAHB housing market index on August 17, housing starts and building permits on the 18th, the FOMC minutes on the 19th, weekly jobless claims on the 20th, and the flash S&P Global US PMI on the 21st. The FOMC minutes on the 19th stand out in particular – they’ll show how many committee members were pushing for a rate hike at the July meeting.
Wrap-Up
Today’s session in Japan was a study in contrasts: the Nikkei extended its win streak to five days on the back of chip and AI stocks, while the TOPIX slipped. What caught my eye is that more stocks fell than rose even as the Nikkei climbed – a reminder that it’s worth looking beyond the Nikkei’s headline move and checking the TOPIX and the advance-decline numbers too. There’s no major US data release tonight, but markets will likely be in a holding pattern ahead of this week’s FOMC minutes.
