M. Nafan Aji Gusta, Senior Technical Analyst at Mirae Asset Sekuritas Indonesia, assessed that market sentiment is turning positive following news regarding the potential easing of tensions in the Middle East. “Market sentiment has shifted slightly positive following reports suggesting that the White House is open to considering a review of sanctions against Iran to alleviate geopolitical conflict tensions,” Nafan wrote in the Strategy Notes & JCI Technical View: Room for a Recovery report, quoted on Wednesday.

This news has eased concerns regarding energy supplies and pressured global oil prices. At Tuesday’s close, WTI crude oil fell by 3.95% to US$88.95 per barrel, while Brent corrected by 1.99% to US$95.88 per barrel.

The decline in oil prices has also helped ease global inflationary pressures. Simultaneously, the 10-year US Treasury yield corrected by 0.10% to the 5.24% level.

Nevertheless, market participants are still awaiting several important US economic data points, ranging from the Personal Consumption Expenditures (PCE) price index to economic growth and non-farm payroll reports. On an annual basis, headline PCE inflation is projected to remain at 3.7%, while core PCE is expected to be at 3.3%. Both figures remain above the Federal Reserve’s inflation target of 2%.

Price pressures also persist as US consumer spending remains strong. Consumer spending in August is expected to grow by 0.8% month-on-month, significantly higher than the 0.2% increase in July.

“The combination of persistently high inflation and resilient consumption could signal that US domestic demand has not weakened enough to provide significant downward pressure on prices,” Nafan wrote.
