U.S. used car prices fell sharply in October, but this decline was offset by significant increases in healthcare goods and transportation costs (the latter being a super-core component closely watched by the Federal Reserve), suggesting a risk that the previous surge in energy prices may be spreading to core indicators. However, U.S. gasoline prices only fluctuated slightly downwards in October, before plummeting in November. If this trend continues, U.S. inflation data for November may still decline, thus mitigating the impact of the October figures.
