NEW YORK, Nov 16 (Reuters) - The dollar fell against the yen on Tuesday after a government report showed U.S. core producer prices unexpectedly fell in October to post their largest decline in more than four years, underscoring the Federal Reserve's concerns about the low inflation environment.
Against the yen, the dollar fell to 83.03 from 83.19 previously to the release of the data.
The producer price index rose 0.4 percent in October while the core PPI fell 0.6 percent.
Analysts polled by Reuters had forecast headline PPI to rise 0.8 percent in October and core prices to rise 0.1 percent. (Reporting by Nick Olivari. Editing by W Simon )
