Oil Prices Put Pressure on Markets
Stocks started the shortened week lower as investors returned from the Labor Day weekend to rising oil prices and continued uncertainty surrounding developments in the Middle East. Investors were also looking ahead to inflation reports later in the week.³
Pressure continued Wednesday as oil prices climbed. The Treasury Department announced plans to triple its long-dated debt buyback program to as much as $6 billion, but the yield on the 10-year Treasury note still rose to a three-year high. Concerns about inflation continued to weigh on markets as the week progressed.⁴˒⁵
Stocks rebounded Friday after inflation data showed annual price increases holding steady in August. Oil prices fell, helping markets recover some of their losses before the weekend.⁶
Inflation Data Takes Center Stage
Investors received two closely watched inflation reports during the week.
The Producer Price Index (PPI), which measures wholesale inflation, rose 0.4% in August from the previous month, in line with expectations. Stocks remained under pressure as investors continued to focus on the broader inflation outlook.⁷
Friday's Consumer Price Index (CPI) report showed year-over-year inflation holding steady at 3.4% in August. Markets responded positively, with attention increasingly shifting toward the Federal Reserve's upcoming meeting and its next decision on interest rates.⁸
The latest reports kept inflation and interest rates firmly in focus as investors headed into an important week for the Federal Reserve.
