The U.S. Treasury market was mixed on Wednesday, with long-term Treasurys generally rallying further on safe-haven demand, while higher-than-expected U.S. PPI data pushed short-term yields higher. The day's Fed minutes were generally uninspiring. Looking ahead to the day, market focus is expected to shift to the upcoming U.S. consumer price index for September, the most crucial economic indicator ahead of the Fed's November decision.
