The Dax returned briskly above the 15,000-point mark on Tuesday. The recovery that had begun the day before after the initial shock in connection with the necessary Credit Suisse bailout continued the day before the US interest rate decision. In early trading, the leading index gained 1.25 percent to 15,119.69 points. The M-Dax gained 0.96 percent to 26,847.92 points and the leading eurozone index EuroStoxx 50 even rose by 1.3 percent.

In the wake of the continuing uncertainty in the European banking industry, the Dax had fallen to its lowest level since the first days of the year at the beginning of the week. However, he then managed an impressive recovery by more than 500 points at times and closed clearly in the plus. In the banking sector, too, relief over the rescue of Credit Suisse ultimately prevailed.

The prospect of a slowdown in interest rate hikes by the US Federal Reserve was also seen as a factor that attracted investors again. When the Fed announces the interest rate decision on Wednesday, the monetary authorities are likely to become more cautious because of the recent turmoil in the banking sector, so the belief.

According to Commerzbank, the market is no longer even pricing in an interest rate hike of 25 basis points, but sees only a small opportunity for it.

The stress in the banking sector has initially subsided, said Jochen Stanzl, analyst at broker CMC Markets. "The market is also betting that the US Federal Reserve will flip the switch again tomorrow to a somewhat more relaxed monetary policy."

Meanwhile, the prospect of selling the steel division prompted investors to access Thyssenkrupp. The shares rose by up to 3.7 percent. The "Handelsblatt" reported that the investment bank Goldman Sachs, which was commissioned with the sale, had found a possible buyer in the financial investor CVC. "CVC can now bring new momentum to this important issue," said one trader.

Investors also took a positive view of RWE's outlook. The shares of the energy group rose by more than two percent, according to figures. The solid outlook and dividend outlook supported the stock, according to traders.
