U.S. stock index futures bounced back on Thursday ​as optimism about a Middle East peace deal lifted sentiment, tempering worries about a hawkish Federal Reserve under ‌new Chair Kevin Warsh. All three major indexes fell in the previous session as investors priced in the likelihood of more Federal Reserve rate hikes, after Warsh underscored the need to curb inflation and other policymakers signaled higher borrowing costs ahead. "The combination of a new chair regime, hawkish projections, and a wide dispersion of views implies a higher ​bar for near-term action in either direction," said Mark Haefele, chief investment officer at UBS Global Wealth Management.
