No; and same with gas. But no matter that, it will mean that prices for other things on the market that have nothing to do with bread or wheat, will go down, because people will have fewer dollars left in their pockets after buying bread.
Bread is actually a much better example than you probably think it is because just like with gas, demand on it is inelastic, people will buy it even if price goes up.
Difference with imported vs domestic oil (or wheat) is that if it is imported (or net imported at least), higher price means that everyone overall has less money in their pockets because some of it was sent abroad, so the economy may be suppressed, if the oil (or wheat) is domestic, it is other way around.
