Markets will look for clues on how policymakers view the latest economic data, Treasury market volatility and government support measures.

Traders are currently pricing in one 25-basis-point rate hike by the end of 2026, according to LSEG data.Dow Jones Today | Nasdaq | S&P 500 Live Updates: Nvidia earnings put AI rally to the testNvidia’s upcoming quarterly results are expected to be a major catalyst for markets, with investors looking for evidence that demand for artificial intelligence remains strong. However, strong earnings may not automatically lift AI stocks as concerns about stretched valuations and AI financing have grown. Bloomberg also reported that some major Nvidia customers had been told server prices containing its AI chips could rise by more than 15%. Nvidia shares fell 0.72% in premarket trading.Dow Jones Today | Nasdaq | S&P 500 Live Updates: Treasury yields remain a key market riskRising Treasury yields have emerged as another major concern for equities.

Higher borrowing costs have particularly hurt growth-oriented technology stocks, contributing to losses across Wall Street’s three major indexes last week. Investors remain focused on whether the Treasury, Federal Reserve or bond market will ultimately determine the direction of the long end of the US yield curve.Dow Jones| Nasdaq | S&P 500 | US Stock Market Today | Live Updates: Iran tensions put Wall Street on edgeUS stock futures slipped on Monday as investors assessed the risk of a fresh escalation between Washington and Iran.
