World trends

War & Conflict

As of Thursday 22 October. In Russia-Ukraine, Russia attacked 12 regions on the night of 21-22 October, right after Putin agreed in principle to resume trilateral talks after 10 November, and Zelensky claimed 21 ballistic missiles on Kyiv were not intercepted (casualties provisional, single-source). On Iran, Araghchi reaffirmed that Hormuz stays closed and reports emerged that the US is sending a third aircraft carrier and weighing strike options, raising the risk of renewed clashes, and Brent hit $113, the highest since May. In Yemen, the Houthis attacked King Fahd airport in Dammam, Saudi Arabia (2 dead per Al Jazeera, single-source and unconfirmed). No new developments were reported in the other conflicts on 22 October.

Geopolitics & Diplomacy

Russia-Ukraine: at the 21 October Witkoff-Putin meeting, they agreed in principle to resume three-way talks after 10 November (Abu Dhabi mentioned) and an American prisoner was released. Zelensky wants early November and is cautious. A report of a large-scale strike on Kyiv right after the meeting limits trust.

Iran: Araghchi reconfirmed that the Hormuz closure will be maintained until the seven-day plan and the Islamabad MOU are implemented. Indirect talks via Pakistan and Qatar continue, but Trump hinted at renewed attacks and the IRGC threatened US bases, raising tensions.

Gulf: after Riyadh, the Houthis attacked King Fahd airport in Dammam, and Al Jazeera reported 2 dead on 22 October. Saudi-Yemen tensions are widening.

Elections: Serbia (25 October general election, Vucic challenging for prime minister), Bulgaria (25 October presidential election) and Israel (27 October general election) are imminent. The latest poll figures for all three could not be confirmed.

Diplomacy: Canadian Prime Minister Carney made his first bilateral visit to Turkey (21-23 October), discussing energy, defence and a free trade agreement.

Health: Congo's government tally for Ebola is more than 8,400 cases and over 4,000 deaths, with Kenya's first confirmed case and death (6 October). New figures for 22 October are unconfirmed.

Finance & Economy

The New York regular session on Thursday 22 October plunged, led by tech stocks, as worries over the profitability of AI investment spread again. The Nasdaq fell 2.60% to 26,008.86, its biggest drop since June, and the S&P 500 closed at 7,663.43 (-1.21%). The Dow, by contrast, held roughly flat at 52,867.98.

The trigger was Meta's earnings. Third-quarter results beat expectations, but it raised its capex outlook and said it would issue new non-voting shares to fund AI, sending its shares down about 6-7%. Amazon (-4.6%), Alphabet (-3.2%) and Tesla (-3.1%) followed, and the semiconductor index plunged about 6.7%. The VIX rose 14% to 19.04.

Bonds traded as a safe haven. The US 10-year yield fell 15.8bp to 4.961%, dipping below 5% for the first time in about a month. Herald Business reported that, per CME, the probability of an October hike had fallen to 7.2%. A hold at 3.75-4.00% at the 27-28 October FOMC is the base case.

Energy moved the other way. On intensified Houthi attacks on Saudi Arabia and reports that the US and Israel are considering renewed strikes on Iran, Brent rose 4% to close at $113.17 and WTI at $99.47. Gold fell 2.85% to about $4,023 on oil-driven inflation worries, and Bitcoin slid to about $81,000 on the risk-asset sell-off.

Asia was already selling before the US session. The KOSPI closed down 3.52% at 5,533.77, led by Samsung Electronics (-4.0%) and SK Hynix (-5.5%), also reflecting weaker supply and demand after the end of share buybacks. The Nikkei fell 2.65%, the Hang Seng about 3%, Shanghai 1.5% and Taiwan's weighted index about 1.8%.

On currencies, USD/KRW was stable at ₩1,324.2, and the yen strengthened on risk aversion (USD/JPY around 157.2). The euro was weak on French political instability, but its close could not be confirmed. The next variables are SK Hynix's third-quarter results and the FOMC on 27-29 October.

Tech & Energy

Energy: Reports of tanker strikes and mine damage around Hormuz, intensified Houthi attacks on Saudi Arabia and talk of renewed US-Israeli strikes on Iran sent Brent to a close of $113.17 (+4%) on 22 October, its highest since May, and WTI to $99.47.

Chips and AI: After Meta raised its AI capital spending outlook and announced a plan to issue new non-voting shares, AI financing worries spread and the semiconductor index plunged about 6.7% (reported). In South Korea, Samsung Electronics fell 4.0% and SK Hynix 5.5% as fears of a memory slump (CXMT's catch-up, 2029 oversupply) continued.

TSMC reaffirmed its 2026 capex of $60-64 billion, and there are reports that it is exploring substitutes for rare-earth components used in equipment (report date unclear).

Critical minerals: There is no new news on an extension ahead of 10 November, when the suspension of China's expanded rare-earth controls expires. Another report gives a different date of 27 November for separate suspensions such as gadolinium.

On 21 October TI reported third-quarter revenue of $6.06 billion (+28% year on year), suggesting an analog recovery, but its fourth-quarter guidance and the market reaction are unconfirmed.

Scheduled: SK Hynix third-quarter results (27-29 October), the FOMC (27-28 October) and the 10 November expiry of the rare-earth controls suspension.

Active conflicts

Key indicators

US Fed Funds Rate3.75~4.00% ―Unchanged on 22 October, held after the 16 September hike. A hold at the 27-28 October FOMC is the base case, and the probability of an October hike fell to 7.2% on CME data cited by Herald Business (the earlier “hold ~83%” figure could not be reconfirmed).
S&P 5007,663.43 (-1.21%) ▼Down 1.21% (matches the previous day's 7,757.17). Worries over Meta's AI investment and issuance of non-voting shares, and a surge in oil prices. The Dow held at 52,867.98 (+0.02%), with large value stocks resilient. Some outlets (Sunday Guardian) show 7,658.24, which is presumed to be an intraday value.
Nasdaq Composite26,008.86 (-2.60%) ▼Down 2.60% (-694.00 points), the biggest drop since June. The semiconductor index fell about 6.7%, Meta about 6.8%, Amazon 4.6%, Alphabet 3.2% and Tesla 3.1%.
US 10-Year Yield~4.96% ▼4.961% (-15.8bp; matches the previous day's 5.119% by back-calculation). Below 5% for the first time in about a month, as AI jitters and Middle East tensions drove safe-haven demand. Yields fell despite the oil surge.
VIX Volatility Index~19.0 (+14.2%) ▲19.04 (+14.15%) on 22 October (the back-calculation matches the previous day's 16.68). It is a single report, so the official CBOE close is unconfirmed.
Crude Oil (WTI / Brent)WTI ~$99.5 (December contract) / Brent ~$113.2 ▲WTI rose 2.39% to 99.47 (matches the previous day's 97.15 in a check) and Brent rose 4% to 113.17 (matches the previous day's 108.79 in a check), the highest since May. Houthi attacks on Saudi Arabia intensified, and the US and Israel are reportedly considering renewed strikes on Iran. The WTI contract month is presumed to be December (not confirmed in reports).
Gold~$4,023/oz ▼On 22 October gold fell 2.85% to $4,022.89 (blockmedia and Etoday agree; futures vs spot not specified and the December contract settlement unconfirmed). It plunged on oil-driven inflation worries. The arithmetic matches the previous day's roughly 4,140.
Bitcoin~$81,300 ▼As a 24-hour asset there is no official close. Traded at 81,342 (-3.65%) in step with the Nasdaq plunge, with outlets showing a range of -1.4% to -3.8%, and $470 million in long liquidations. Shown as about 81,300.
KRW/USD₩1,324.2 (22 October Seoul 15:30 close) ―Down ₩1.0 (matches the previous day's ₩1,325.2 in a check). New York overnight trading at ₩1,325.09-1,327. Stable despite the KOSPI plunge.
JPY/USD~¥157.2 ▼Based on 157.168 (-0.65%, the biggest one-day yen gain in a month) in New York in the morning; the official close is unconfirmed. Risk aversion and lower US yields were the drivers.
EUR/USDAbout 1.122 (flat) ―The 22 October close is unconfirmed, so the previous value is retained. There were reports of euro weakness, with EUR/JPY down 1.0% to 175.91 on French political and bond-market unrest, but the direction is not fixed into the value.
KOSPI5,533.77 (-3.52%) ▼Down 201.89 points (-3.52%; matches the previous day's 5,735.66). The third drop of 3% or more in six sessions. Samsung Electronics fell 4.03% (₩214,500) and SK Hynix about 5.5% (in the ₩1.22 million range), affected by the end of share buybacks. The KOSDAQ was 764.10 (-3.62%).
