Ibex 35 today: opening still without verifiable data

The IBEX 35 starts the day focused on the Fed and oil: Ibex 35 today: opening

Ibex 35 today: opening: updated analysis with context for investors.

IBEX 35: market open

Trading on Wednesday, September 16, 2026 officially began at 9:00 a.m. Madrid time, but as of 9:17 a.m. the public pages consulted still do not provide a verifiable quote corresponding to today’s opening. The latest clearly identified records are still dated Tuesday, September 15. Therefore, it would not be rigorous to present that level as this morning’s opening.

The valid reference for measuring the initial move is yesterday’s close: 19,555.90 points, down 0.05%. That figure serves as a point of comparison, but it should not be confused with Wednesday’s opening price. Nor can the previous opening of 19,509.80 points be reused. The message for investors is straightforward: until a first reading from today is available with confirmed date and time, any percentage attributed to the IBEX 35 would be an estimate, not market data. The priority should be to interpret real figures, not fill the gap with false precision.

Factors shaping the opening of the Spanish market

The day’s main catalyst is the Federal Reserve’s rate decision. The market assigns a 92.4% probability to a 25-basis-point hike, according to information reported by Cinco Días on the stock market session. What matters is not only whether the Fed raises the price of money: the reaction will depend on the message regarding inflation, growth, and future moves. Guidance that is more hawkish than expected could push bond yields higher and pressure indebted companies.

The 10-year US Treasury yield briefly moved above 5% on Tuesday and this morning was trading around 4.98%. That level makes financing more expensive, raises the required return on equities, and may favor a rotation toward financial stocks. In Spain, the performance of Santander, BBVA, CaixaBank, Sabadell, Bankinter, and Unicaja will be decisive because of their high combined weight in the index.

Oil offers some relief, although it remains in an extremely demanding range. Brent is down around 0.6%, but still remains close to $108 a barrel after posting roughly a 20% monthly gain. Tensions around the Strait of Hormuz and problems with Saudi Arabia’s East-West pipeline keep supply risk alive. At the same time, the euro is trading near $1.154, an important reference for exporting companies and for the market’s reading of the Fed.

Sectors and stocks leading the start of the session

Without dated and verifiable quotes from today as of 9:17 a.m., it still cannot be stated which sector is actually leading. The map investors should follow is clear: banks may benefit from expectations of higher rates, while airlines, tourism, industry, and consumer sectors face pressure from crude still close to $108. Repsol could react to the price of Brent, but a decline in oil does not automatically imply a drop in the stock because refining margins and geopolitical news also matter.

Stocks rising and falling the most at the open

The tables available in the financial media consulted continue to show changes corresponding to the close on Tuesday, September 15. Using those percentages to draw up a ranking of Wednesday’s winners and losers would be mixing two different sessions. For that reason, no gains for today are attributed to Acciona, Acciona Energía, Repsol, or Acerinox, even if they appear among the standout stocks in earlier records.

The same caution applies to declines. The moves shown for Solaria, Puig, Inditex, Amadeus, Santander, or BBVA belong to Tuesday and do not allow us to determine who is leading the losses this morning. The market calendar published by Investing.com confirms that the Fed, the euro, oil, and macroeconomic releases are drawing the focus, but it was published before the open and does not include a verifiable ranking for the newly started session.

What to watch during today’s session

The first technical level is 19,511 points, Monday’s intraday low. If the IBEX loses that area with participation from the banks and Inditex, the risk of further downside would increase. On the upside, a clear recovery above 19,600 points would improve the initial picture. Also watch the 10-year US Treasury yield, Brent around $108, the euro against the dollar, and market breadth. A rise sustained by only a few heavyweight stocks does not have the same quality as an advance accompanied by most of the index. Today, discipline means waiting for confirmation, measuring sector performance, and not getting ahead of the Fed’s verdict.
