Analyst initiations:

I am the Global Editor at MoneyShow.com and each week I interview an investing expert. This week, I spoke with Christoph Scherbaum, editor of the German edition of Personal Finance, who says German investors are cautious, but optimistic about their market.

Q. Christoph, some experts predict the beginning of a prolonged slowdown that will push consumer price inflation in Germany to as low as 2% next June. What do you think?

A. Consumer prices are not really a problem. August inflation was less than 4% and is estimated at 3% until year-end. The delayed effects of rising commodity prices will have a steeper decline. In addition, second-round effects through higher wage developments are now more visible. Therefore, the European Central Bank-despite poor economic data-will wait for a reassessment of its inflation target for 2010 until the second half of 2009

Q. To what extent do you think the US's financial worries are extending to German financial institutions?

A. It's a difficult question, but we have no big problem with our banks. German Finance Minister Peer Steinbrueck recently stated: "Although this financial crisis undoubtedly is the biggest economic risk for the German economy, I think the potential impact on us-after inquiries and interviews with the Bundesbank president-to be limited". He also reaffirmed the intent of a balanced federal budget in 2011.
