"One, letting interest rates unchanged, another one decreasing interest rates."

Central banks including the ECB and U.S. Federal Reserve have thrown lifelines to interbank money markets by pumping huge amounts of cash in a bid to keep credit flowing but those operations cannot resolve the crisis.
The Fed's key interest rate now stands at 2 percent meanwhile, which does not leave it much room for maneuver to the downside.
Many observers say the worst financial crisis since the 1930s Great Depression will only begin to improve when commercial banks regain enough faith in each other to begin lending on interbank markets again.
Against the backdrop of financial turmoil, analysts will listen closely for what Trichet tells media about the bank's monetary policy and the economic outlook in general.
