The first session of the week in the US was marked by insignificant fluctuations in anticipation of the FOMC meeting results, which will be announced tomorrow.

Everything points to reinforce the expectation that today's session will look similar.

The downward start on Wall Street was expected after an earlier, rather weak, behavior of futures, which indicated a 0.5% decline at the opening.

Also consequential is the decline in oil quotations, which was largely ignored yesterday by Wall Street, but was spotted by the mining companies.
