Problems of European, and first of all of Swiss Credit Suisse Bank banks, became the main news of Wednesday's trading on the US stock market. Market participants actively urged key European regulators to clarify the situation with credit institutions and their guarantees for depositors and investors. Cautious promises of the regulators were heard by the market, which together with expectations of a sharp change of the vector of interest rates both in the US and the EU, as well as expectations of additional liquidity, which the Fed and the ECB can provide to the banking sector, kept markets from collapsing, leading them to decline at the close within one percent. The main outsiders of trades were expectedly the shares of Financial sector, as well as the shares of Energy sector, driven by a significant decline in oil prices.
