Global Market Today: Asian shares slip as US stock futures dip ahead of Warsh’s Jackson Hole speech

US stock futures declined as investors awaited Federal Reserve Chair Kevin Warsh's upcoming speech in Jackson Hole, where hawkish expectations loomed. The Nasdaq 100 Index futures dropped 0.3%, while the S&P 500 Index futures fell 0.2%. Initial excitement surrounding the artificial intelligence sector due to Nvidia Corp.'s positive outlook faded.

Marvell Technology Inc. suffered a more than 7% drop in after-hours trading following a weak earnings report. The Asia Pacific equities index declined, with South Korean shares falling 1.3%. Treasuries slipped for a second consecutive day, with yields rising two to three basis points due to inflation and fiscal concerns. US crude hovered around $83.40 per barrel, despite potential obstacles in diplomatic talks regarding the Strait of Hormuz.

Venezuela is reportedly considering exiting OPEC, according to sources. Warsh's speech will provide crucial insights into whether the recent bond yield surge will persist and how the Fed will balance inflation and an easing economy. A lack of clarity on the Fed's policy direction could intensify volatility in long-term Treasuries, which could have spillover effects on stocks.

Torsten Slok, chief economist at Apollo Global Management, warned that a lack of framework guidance from Warsh could lead to significant moves in long rates. Traders analyzed recent clues on the Fed's policy path, such as a decrease in US jobless claims and a rise in wholesale inventories, while the July merchandise trade deficit reached its largest level since early last year.

Kansas City Fed President Jeff Schmid stated that monetary policy was not hampering economic growth. The Fed maintained the federal funds rate range at 3.5% to 3.75% at their latest meeting, with futures pricing in a quarter-point increase by year-end. Warsh's Jackson Hole speech offers an opportunity to curb the ongoing decline in long-term Treasuries, as clarity on the Fed's inflation reaction function could help reduce uncertainty-related term premiums.

A clear policy signal from Warsh is unlikely due to his reluctance to provide forward guidance, according to analysts. Instead, Warsh may preview the Fed's five working groups' early findings on communications, the balance sheet, economic data, productivity, jobs, and the inflation framework.
