World trends

War & Conflict

No new war-level event occurred between 19 and 20 September (KST), but Iran passed the US three conditions for ending the war via Qatar (a full halt on all fronts, release of frozen assets, and lifting of the naval blockade), opening a negotiating channel in the tanker-war phase. The Yemeni western front escalated, with 194 killed and 880 injured over two weeks, and in Gaza deaths from strikes continued under the ceasefire (cumulative toll above 1,300).

Geopolitics & Diplomacy

Iran has conveyed to the US, via Qatar, three conditions for ending the war (a complete halt on all fronts, release of frozen assets and lifting of the naval blockade) and is awaiting President Trump's reply. It is the first time since the war began that a specific negotiating track has been made public, so it could be a watershed that decides the course of the tanker war.

In Gaza, sporadic airstrikes continued even after the October ceasefire, and an Israeli strike on 19 September killed four people, including the son of Munir al-Bursh, director-general of Gaza's Health Ministry; cumulative deaths since the ceasefire took effect have passed 1,300.

In Yemen, after the Houthis took most of the western coast with their victory in the Battle of Mocha, fighting with government forces intensified, leaving 194 dead and 880 injured in the past two weeks, and on the Israel-Lebanon border three people were killed in Israeli retaliatory strikes for a Hezbollah drone attack, so casualties rose on both fronts.

The fallout from the Graham Act taking effect continues, with India, a major buyer of Russian crude, exposed to the threat of tariffs of up to 100%, while Russia invited international condemnation by pressing ahead with its first-ever local elections in forcibly annexed territories.

On the large-scale health and disaster axis, the Ebola outbreak in the Democratic Republic of Congo was revised up again to 7,475 confirmed cases and 3,605 deaths, and the DRC and Rwanda held talks in Geneva to review implementation of the Washington peace agreement but failed to narrow differences over core obligations such as disarming the FDLR.

Finance & Economy

The Bank of Japan raised its policy rate to 1.25% on 18 September, the highest since 1995, but two of nine board members dissented and Governor Ueda gave no hint of further hikes, so it was not read as a hawkish hike and the yen actually weakened.

Argentina's country risk (EMBI) closed at 526bp, up 44 points on the week, its largest weekly rise in six months, raising wariness about emerging-market credit risk.

Eleven of the 12 major indicators kept their Friday 18 September regular-session closes because of the weekend closure: the S&P 500 and Nasdaq finished slightly higher despite triple witching, and the KOSPI closed up a sharp 2.66% on a surge in large-cap chip stocks.

Bitcoin rose more than 4% in 24 hours to about $81,300 on ETF net inflows and a record mining difficulty, and, as an asset that trades around the clock, was the only one with a substantive update over the weekend.

In Australia, the probability of an RBA hike on 29 September rose further to 72-87%, while in Mexico "progress" was mentioned in Trump-Sheinbaum tariff talks but no final deal was reached, pushing negotiations to a follow-up round on 28 September.

Tech & Energy

Ahead of Xi Jinping's 24 September visit to the US, the Trump administration is considering delaying formal notification of a $14 billion Taiwan arms sale until after the November APEC summit (Shenzhen) and December G20 summit (Florida). Since China had warned it would cancel the summit if the sale were approved beforehand, the consideration of a delay is read as a conciliatory signal from the US to save the summit.

The Bank of Japan's rate rise to 1.25% (the highest in 31 years) is expected to affect yen funding costs for chip and AI investment, but the yen itself turned weaker, so the immediate spillover was limited.

Huawei reconfirmed the launch schedule for the Ascend 960DT unveiled at Huawei Connect 2026 as the first quarter of 2027, three quarters earlier than planned, again stressing the speed of its catch-up with Nvidia.

Russia protested the Graham Act's entry into force as an ‘unfriendly measure’, and there is concern it could also hurt Russia-Ukraine peace talks; US energy sanctions on Russia have emerged as a new variable in the contest for technology and energy supremacy.

In India, SEMICON India 2026 closed after running 17-19 September, with 25 new partnerships in the chip supply chain signed, including Tata Electronics-Inox Air Products, Sumitomo Chemical and Kellington Engineering, giving shape to phase two of India's Semiconductor Mission.

Active conflicts

Key indicators

US Fed Funds Rate3.75~4.00% ―The increase from the 17 September FOMC is maintained. No change until the next FOMC (none this weekend).
S&P 5007,650.50 (+0.17%) ―Based on the Friday 18 September regular-session close; markets closed for the weekend. It edged higher amid the second-largest triple witching on record (about $7 trillion of options expiring).
Nasdaq Composite26,522.55 (+0.39%) ―Based on the regular-session close on Friday 18 September; markets closed for the weekend.
US 10-Year Yield~4.94% ―Based on the Friday 18 September close; unchanged because the bond market is closed for the weekend.
VIX Volatility Index15.44 ―Based on the Friday 18 September close; markets closed for the weekend.
Crude Oil (WTI / Brent)WTI ~$100.30 (-1.58%) / Brent ~$103.87 (-0.91%) ―Based on the regular-session close on 18 September (Fri); markets closed for the weekend. Some Asian outlets reported that prices ‘fell below $100’, but this reflects the same 18 September (Fri) NY session being dated 19 September because of the time difference, not a change in the regular-session close.
Gold~$4,385/oz ―Based on the close on Friday 18 September; the spot market is closed over the weekend.
Bitcoin~$81,300 ▲Live update, as a 24-hour trading asset. On Saturday 19 September, Bitcoin broke back above $81,000 (intraday $81,256-81,354, up about 4.2% on the day) amid net inflows of about $433 million into US spot Bitcoin ETFs and a record high in mining difficulty. The Fear & Greed Index is at 71, ‘greed’.
KRW/USD₩1,383.3 (+0.08%) ―Based on the Seoul FX market close at 15:30 on 18 September (Fri). The domestic spot market is closed at weekends (the won-dollar pair trades 24 hours but not on weekends or 1 January). No clear direction was confirmed in the offshore NDF market, so it is not reflected as a confirmed value.
JPY/USD~¥156.26 ―Based on the NY close on 18 September (Fri). Even though the BOJ raised its policy rate to 1.25% (the highest in 31 years) the same day, the yen weakened (intraday 156.64) after a 7-2 board vote and cautious remarks from Governor Ueda. With no weekend moves, the previous close is retained.
EUR/USD~1.1461 ―Based on the Friday 18 September close; markets closed for the weekend.
KOSPI6,894.23 (+2.66%) ―As of the close on Friday 18 September (large-cap chip stocks surged and foreigners turned net buyers for the first time in 8 sessions). Unchanged because of the weekend market holiday.
