Stocks and bonds experienced a decline on Tuesday, while oil prices saw an increase, reversing earlier trends. This shift in market sentiment was largely driven by a lack of progress in diplomatic efforts to end the US-Iran conflict, which had previously offered some relief to investors. Brent crude, which had fallen towards $98 earlier, regained ground and hovered near $100 a barrel, reflecting renewed concerns about supply disruptions and inflationary pressures. West Texas Intermediate (WTI) crude also settled higher at $90.52/bbl, up from an earlier low of $93.28/bbl.

The equity markets were mixed, with the S&P 500 futures little changed or slightly down, and the Nasdaq 100 showing minor gains or losses. The Dow Jones Industrial Average also saw fluctuations, closing down around 0.36%. While AI-linked stocks initially saw positive momentum following Meta Platforms Inc.'s new AI agent, the broader market remained sensitive to macroeconomic risks. Microsoft Corp. rose 0.9% in premarket trading, but an exchange-traded fund tracking chipmakers was slightly lower, indicating varied performance within the tech sector. Overall, global stocks reflected a cautious sentiment, with the MSCI World Index little changed.

Bond yields, which had eased slightly earlier in the week, saw renewed pressure. The yield on 10-year Treasuries, after declining two basis points to 4.93%, ended up slightly at 4.967%. This uptick in yields, despite earlier declines in oil prices, suggests that traders are still factoring in potential interest-rate hikes and persistent fiscal shortfalls. Federal Reserve Bank of Boston President Susan Collins indicated support for recent rate hikes, stating that a more restrictive federal funds rate would help in achieving price stability, especially after five and a half years of high inflation. Gold also saw a slight dip, with spot gold falling 0.5% to $4,321.83 an ounce. Cryptocurrencies also declined, with Bitcoin falling 1.2% to $85,903.54 and Ether falling 1.5% to $2,742.14.
