Global Mood: Cautiously Risk-off
Drivers:
Higher US yields, Iran-US talks, Trump-XI Summit

Asian markets turned cautious to risk-off on Thursday, as a sharp rise in US Treasury yields raised expectations of further Federal Reserve tightening and pressured risk assets. Japan’s Nikkei 225 rose 0.64% after a three-day holiday, while Topix fell 0.17% and Australia’s ASX 200 declined 1.33%; South Korea was closed. SGX Nifty was down 164.5 points, or 0.70%, at 23,281, pointing to a weaker opening for Indian equities.

The US 10-year Treasury yield climbed to 5.135%, its highest since July 2007, as stronger US activity and renewed inflation pressures lifted expectations for further Fed tightening. Brent rose above $101 a barrel, while US diesel topped $6.50 a gallon, adding to concerns over broader price pressures. Fed Governor Michael Barr indicated further policy adjustments could be needed. Meanwhile, Iran said major differences remain in indirect talks with Washington, keeping uncertainty around the Strait of Hormuz elevated.

THE BIG STORY
US business activity strengthened sharply, while input-price pressures hit a near four-year high. Fed Governor Michael Barr said further policy adjustments are likely as inflation risks rise.

Brent rose above $101 a barrel and US diesel prices topped $6.50 a gallon, increasing costs across the transport and production chain.

Tehran said major differences remain despite indirect talks, with reopening the Strait of Hormuz and lifting the US naval blockade among its key demands. Traffic through Hormuz has improved, but about a third of Gulf oil supply remains missing from global markets, keeping refined-fuel shortages elevated.

Russian drones hit Kyiv infrastructure and fuel stations, while Ukraine pushed for an energy ceasefire ahead of winter.

Data Spotlight
The S&P Global US Flash Composite PMI rose to 58.4 in September from 56.0 in August, the strongest expansion since July 2021, as services hit a five-year high of 58.7 and manufacturing accelerated to 56.7. 

The 30-year fixed mortgage rate climbed to 7.12% in the week ending September 18th, the highest since May 2024, after the Fed's 25 basis point hike and hawkish signals from Chair Warsh.  Rates have risen over 100 basis points since strikes against Iran began in late February, with total mortgage applications falling for a third consecutive week.

The Richmond Fed Manufacturing Index fell to -2 in September from 4 in August, its first negative reading in six months, as shipments and new orders both contracted. 

Takeaway: The US private sector's strongest expansion in over five years contrasts sharply with regional manufacturing weakness and mortgage rates breaching 7% for the first time since 2024. Intensifying price pressures and hawkish Fed signals suggest the cost of this growth momentum is rising, keeping the inflation and rate outlook finely balanced.
