FX.co ★ US premarket on September 13: Stock market keeps steady after inflation data

US stock index futures rebounded after US inflation data, which slightly missed economists' expectations. S&P 500 futures rose by 0.2%, while the tech-heavy NASDAQ jumped 0.53%. Bonds and the dollar saw minor changes, as the mixed inflation report fueled speculation that the US Federal Reserve might hold off on interest rate hikes but refrain from announcing an end to its tightening cycle.

The yield on two-year Treasury notes, which are more sensitive to the Fed's upcoming moves, hovered around 5%.

According to the Labor Bureau report, the core Consumer Price Index (excluding food and energy) increased by 0.3% compared to July but dropped year-on-year to 4.3%. These figures closely matched predictions. The overall Consumer Price Index surged by 0.6% and 3.7%, respectively.

The current inflation report allows the Fed to maintain a more comfortable wait-and-see stance, as the higher-than-expected inflation is mainly driven by energy prices – not a primary concern for the Fed right now.

With inflation seemingly in the rearview, traders now turn their eyes to the latest geopolitical events: North Korean leader Kim Jong-un and President Vladimir Putin met for their first summit in four years. US politicians believe this will allow both countries to focus on arms supplies.
