World trends

War & Conflict

Apart from Yemen, other conflicts saw almost no new developments (for Russia-Ukraine, only the dispute over an energy truce was added). Newly confirmed: a Houthi missile at Riyadh was intercepted and an Aramco building in Dhahran was hit (14 October), and a Saudi coalition claim of strikes on a fuel facility in Sanaa (13 October). A tally of 20 deaths over a week was rejected as it comes from a single summary source.

Geopolitics & Diplomacy

On 14 October the Houthis again fired ballistic missiles at Riyadh, which the Saudi-led coalition intercepted, and an Aramco administrative building in Dhahran was hit. Riyadh airport is still not operating, and the death toll at the airport is given as 12-14, differing by outlet.

The Houthis claimed that Saudi Arabia struck a fuel facility near Sanaa on 13 October, widening the exchange. There are reports of a phone call between the Iranian and Saudi foreign ministers, but the dispatch of military support and the like are not confirmed as they rest on a single-source report.

US-Iran indirect contacts via Qatar continue, but the deadlock remains since Trump rejected Iran's seven-day roadmap in late September. Trump said he would not attack before the midterm elections, and Iran's security chief warned that Iran could attack Gulf data centres and cables if war resumes.

September CPI came in at 3.7%, above expectations, adding political pressure on Trump and the Republicans ahead of the 3 November midterms. A surge in petrol prices is tied to the Iran war and the Hormuz disruption, and the Fed's September rate hike clashes with Trump's pressure for lower rates.

In Russia-Ukraine, the two sides are trading accusations over an energy truce announced unilaterally by Trump, which neither has confirmed. There are signs Russia temporarily avoided energy targets on 13 October, but attacks on cities continued, and Europe is pushing back against the easing of sanctions on Russian diesel.

Reports conflict on the expiry and extension timetable of the US-China trade truce (the earlier extension to 10 January 2027 versus talk of an expiry on 10 November). The controversy over holding back a Taiwan arms sale is an issue. On the election calendar, next come Brazil's run-off, Serbia and Bulgaria on 25 October, Israel's general election on 27 October (with Netanyahu's trial a headwind) and the US midterms on 3 November.

Finance & Economy

US September CPI came in above expectations, at 3.7% for the headline and 2.6% for the core, shifting the market's focus from rate cuts to the possibility of hikes. The energy index (+5.2%) and gasoline (+9.1%) led the increase.

The S&P 500 fell 1.11% to 7,718.94, the Nasdaq 1.88% to 26,692.87 and the Russell 2000 about 2%, as risk assets retreated. The Dow held up relatively well, down 0.09%.

Rates: Reports conflict over whether the 10-year yield rose as high as 5.28% intraday before easing back to around 5.19%, so the official close is unconfirmed. The 30-year was in the 5.5% range.

ASML's third-quarter sales rose 47% and it raised its outlook, but its shares fell about 4%, failing to stop a broad semiconductor decline (seven straight sessions).

Ahead of the CPI release, the KOSPI fell for a sixth straight session to 6,008.81 amid wait-and-see sentiment, and foreign investors were net sellers for a seventh straight session. USD/KRW fell to ₩1,338.3 in daytime trading.

Oil is elevated, with WTI near $95 and Brent near $108, while gold is in the low $4,100s on dollar strength and hike worries. Volatility may increase ahead of the 27-28 October FOMC.

Tech & Energy

On 14 October ASML reported third-quarter total revenue of about €11.7 billion, a margin of 57.5% and net income of about €5 billion. Guidance of €14.2-15.2 billion for the fourth quarter and €44-45 billion for the year shows AI equipment demand continuing. The low end is higher than the July outlook (€43-45 billion), and the earlier €36-40 billion figure was not verified.

TSMC will report third-quarter results at 14:00 (Taiwan time) on 15 October. Monthly revenue totalled about NT$1.49 trillion, a strong figure, and the focus is on margin dilution from the 2nm ramp-up and on 2027 pricing and capital spending.

Confirmed third-quarter figures for Samsung Electronics and SK Hynix are not yet available.

In energy, Qatar's LNG force majeure runs into November and early December, putting winter LNG prices in Europe and Asia at their highest since late 2022. Crude flows through Hormuz have partly recovered, but LNG has no workaround.

On 2 October the G7 agreed to release up to 100 million barrels from reserves. The release is diesel-focused, but refining capacity and logistics constrain actual supply. UK retail diesel prices are at record highs.

There were no new developments on the US-China truce, AI chip export controls or Rapidus on 14-15 October.

Active conflicts

Key indicators

US Fed Funds Rate3.75~4.00% ―Rates have been held since the 25bp hike at the 16 September FOMC (3.50-3.75% to 3.75-4.00%, the first hike in about three years). The next FOMC is 27-28 October; a September CPI (14 October) above expectations increased bets on a hike (Bloomberg-based hike probability about 46%).
S&P 5007,718.94 (-1.11%) ▼Close on Wednesday 14 October, down 86.51 points. A hotter-than-expected September CPI (headline 3.7%, core 2.6%) and a sell-off in AI and chip stocks. The Dow was 51,621.48 (-0.09%). (Arithmetic matches the previous day's 7,805.45 from 13 October.)
Nasdaq Composite26,692.87 (-1.88%) ▼Close on 14 October (Wed) (CNBC). Invezz showed 26,701.48 (-1.85%), a slight discrepancy. Chip stocks fell for a seventh straight session, and the Russell 2000 dropped about 2%.
US 10-Year Yield~5.22% ▼Previous value kept. On 14 October, reports conflict on whether it rose to 5.28% right after CPI before easing back to 5.19%, so the close is unconfirmed (5.19-5.28%). The 30-year was about 5.59%.
VIX Volatility Index15.52 (+1.37%) ―Previous value kept. A Yahoo live snapshot shows 16.87 (+10.5%), but its timing is unclear, so it cannot be confirmed as the 14 October close. The 13 October value is also unconfirmed (15.21 vs 15.52).
Crude Oil (WTI / Brent)WTI ~$94.1 / Brent ~$105.7 ▲Previous value retained; on 14 October, WTI of about 95.07 and Brent of about 108 are intraday snapshots, and settlements are unconfirmed. Gasoline rose 9.1% in September CPI.
GoldSpot ~$4,198/oz ―Previous value retained. Spot gold on 14 October of about $4,127 (Schwab's opening table) is an opening figure and the close is unconfirmed (13 October also varied, at 4,163-4,170). A stronger dollar (DXY 102.62, +0.4%) points to a decline.
Bitcoin~$83,300 ―A 24-hour asset. About $83,300 as of the morning of 15 October (similar to the previous 83,200).
KRW/USD₩1,338.3 (14 October Seoul 15:30 close) ▼Down ₩6.8 (₩1,345.1 on 13 October). This is the Seoul daytime close, before the US CPI release (21:30 Korea time), so New York's reaction is not reflected; dollar strength (DXY +0.4%) may put offshore pressure on the won, but that estimate is not hardened into a value.
JPY/USD~¥158.2 ―Previous value retained; the 14 October close is unconfirmed (DXY +0.4% points to a stronger dollar).
EUR/USD~1.123 (+0.2%) ―Previous value retained; the 14 October close is unconfirmed. The mismatch between the reported 12 October close of 1.1160 and the previous 1.123 is carried over (DXY +0.4%, so a decline is possible).
KOSPI6,008.81 (-0.44%) ▼Close on Wednesday 14 October, down 26.54 points from the previous day's (13 October) 6,035.35 (arithmetic matches; two outlets reported it, independent reconfirmation lacking). Sixth straight decline, swinging from +2.57% (6,190.65) to around 5,940 intraday. Foreigners net sold for a seventh straight day (about ₩1.1 trillion). Reports said Samsung Electronics and SK Hynix turned lower after ASML's earnings.
