South Korean exports set a 20-day record as chip shipments surge

South Korea exported $71.4 billion of goods during September 1–20, up 78.3% from the comparable 2025 period and above the previous 20-day record of $61.7 billion, preliminary customs figures showed. Semiconductor exports reached roughly $34.1 billion, a 259% increase, while imports rose 26.7% to $48.4 billion. Chips supplied about 47.8% of export value, an independently calculated share illustrating the country’s concentration in semiconductor exports. The partial-month figures may not predict September’s final total.

Typhoon Dujuan threatens eastern Japan with flooding

Reporting window: 2026-09-20T00:09:07.279Z–2026-09-21T12:09:07.279Z. Typhoon Dujuan approached Japan’s Pacific coast on September 21 after some locations received more than 300 millimeters of rain from Saturday onward. Authorities issued their highest-level landslide warning for Oshima in the Izu Islands and warned that narrow, persistent rain bands could cause flash flooding around Kanto and central Japan. The storm postponed an Asian Games equestrian event and delayed the prime minister’s flight to New York. Local forecasts remain especially important because rainfall can vary sharply over short distances. Typhoon approaches eastern Japan, prompting flood and landslide warnings

Tropical Storm Polo approaches southwestern Mexico

At 09:00 UTC on September 21, the U.S. National Hurricane Center placed Tropical Storm Polo about 395 kilometers south of Manzanillo, with sustained winds near 75 kilometers per hour. Mexico issued a tropical-storm watch from Tecpan de Galeana to Punta San Telmo. Forecasters expected four to eight inches of rain, with isolated totals reaching 12 inches, across coastal parts of Guerrero, Michoacán, Colima and Jalisco through Thursday. Rapid strengthening was forecast, but Polo’s eventual intensity and track remained uncertain. Tropical Storm Polo Advisory Number 3

India-New Zealand trade agreement will take effect October 20

India and New Zealand completed ratification of a free-trade agreement signed in April and said it would enter into force on October 20. The agreement gives Indian goods duty-free access to New Zealand and removes or reduces Indian tariffs on about 95% of New Zealand’s current exports. The countries recorded roughly $2.3 billion in bilateral trade during the 12 months through June. The agreement expands access for goods and changes mobility and services rules, but its economic effect will depend on how extensively businesses use the preferences.

Global diesel supplies remain unusually tight

U.S. diesel inventories fell to 107.9 million barrels by September 11, their lowest level for that point in the year since records began in 1982, Reuters reported. European stocks at the Amsterdam-Rotterdam-Antwerp hub were 16% below their five-year average in July. The U.S. Energy Information Administration expects domestic distillate inventories to remain below their five-year minimum through most of 2027. Because diesel powers freight, farming, heating and industry, shortages can raise wider costs even when crude prices fall. Higher refining output could offer relief. Global diesel shortage likely to last into 2027 as storage tanks drain

Oil retreats as Saudi exports partly recover

Brent crude fell 2.6% to about $101.20 a barrel by 11:37 UTC on September 21, reaching its lowest level in 11 days. Traders were weighing stronger Saudi shipments through the Strait of Hormuz and the possibility—not confirmed diplomatic progress—that meetings around the U.N. General Assembly could reopen negotiations over the Iran conflict. Satellite data cited by Reuters indicated Saudi flows through Hormuz recently averaged 2.9 million barrels a day, up from 700,000 in August. Continuing fighting and shipping risks leave the supply outlook unsettled despite the price decline. Oil prices slide to 11-day low on hopes of US-Iran diplomacy and Saudi exports

Houthi advance raises new Red Sea shipping risks

Houthi forces advanced toward strategic highlands in Yemen’s Taiz and Lahij provinces that separate the Red Sea coast from government-held southern areas. Five Yemeni military sources told Reuters that capturing the heights could help the group protect positions around the Bab al-Mandab Strait and open additional fronts. The strait connects shipping between Asia, Europe and the Suez Canal and has also served as an alternative route for Saudi oil exports. Further territorial changes could therefore affect both Yemen’s conflict and international trade, although control of the contested areas remained unresolved.

Seven Ethiopian armed groups form alliance

Seven Ethiopian armed organizations announced an alliance late September 20 seeking to remove Prime Minister Abiy Ahmed’s government. Members include the Tigray People’s Liberation Front and the Amhara Fano National Movement, which fought on opposing sides during the 2020–2022 Tigray war. The federal government had not immediately responded to Reuters. The coalition spans several regions and could enable greater coordination among armed groups, but unresolved territorial and political disputes between members make its durability uncertain. Its formation also adds pressure to the 2022 peace agreement that ended the Tigray war. Seven Ethiopian armed groups announce anti-government alliance
