If you do business with Iran, it's probably going to be harder to get insurance coverage. Regulators and lawmakers in the U.S. are looking for stiffer penalties to thrust upon companies that do business with Iran. And insurers, likely acutely aware of how risk can spread, are starting to pull back.

Munich Re (0KFE) and Allianz (AZSEY) announced that they are suspending business in Iran, according to a report by Business Insurance. Neither company, however, stands to lose much. For Allianz, the lost premium is "negligible," and for Munich Re, it's only around $13.6 million.

Long a topic of discussion, insurers and reinsurers are beginning to enter the microinsurance space. Scor (SCOR) firm invested in LeapFrog Investments, the first microinsurance fund, last month, and last week, the Microinsurance Network was launched in an effort to raise awareness of the sector.

In a mature industry, microinsurance is seen as having considerable growth potential, especially given the large numbers of people around the world who live without any form of coverage. Microinsurance protection ranges from property catastrophe to life and health. A recent study by Lloyd's of London found that 135 million people, 5% of the world's low-income people, are using microinsurance products, but that the total market size could range from 1.5 billion to 3 billion.

The banking system has been crumbling for over a year, but last month's collapse of American International Group (NYSE: AIG) -- which prompted an $85 billion government takeover -- suggests that insurance is not immune from the problems. As a reminder, AIG got snared in the $62 trillion Credit Default Swap (CDS) market whose growth was spurred by McCain advisor, Phil "Americans are Whiners" Gramm.

And as insurance crumbles, banks keep suffering. Bank of America (NYSE: BAC) and National City Corp. (NYSE: NCC) are both hurting. How much?

• Bank of America's earnings plunged 68% to $1.18 billion, or $0.15/share -- missing by 60% analysts' forecast of 62 cents. Bank of America will raise capital by selling $10 billion of common stock and slashing its dividend in half from 64 cents to 32 cents. One analyst cut the bank's 2009 earnings estimate to $2.50 per share from $3 per share -- this is well below the $3.12 per share from a Thomson Reuters analyst poll -- and lowered his price target by $2 to $26.

• National City Corp. and its National City Bank both suffered debt downgrades from Fitch. For instance, Fitch slashed the bank subsidiary's long and short-term Issuer Default Ratings (IDR) to A- from A. And it lowered the bank and holding company's Individual rating to C from B.

With rumors of bankruptcy swirling, the shares of Hartford Financial Services Group Inc (NYSE: HIG) have plunged over the past few weeks. Hey, if AIG (NYSE: AIG) can implode, why not the others?

Well, the death of Hartford has been greatly exaggerated. Today, the company announced that it received a $2.5 billion capital infusion from Allianz, a mega German financial firm. Despite today's huge drops in the markets, Hartford's shares spiked 16% to $31.88.

The deal is certainly beneficial to Allianz, which gets preferred stock (that converts to common shares at $31 a piece) as well as junior subordinated debentures (there are also warrants to buy $1.75 billion of Hartford at $25.32). Yet, it's still a nice boost for Hartford.

Essentially, Hartford has an extensive portfolio of investments, which have suffered declines (it looks like the recent carnage in hedge funds was a big contributor). In fact, the company believes that there will be a Q3 loss of $8.50 to $8.80 per share.

But, with the capital infusion, Hartford should weather the storm – as well as be positioned to deal with possible credit downgrades (there will be $3.5 billion in excess capital). What's more, there may be opportunities to capitalize on the wreckage. After all, AIG is preparing to sell a large number of assets.

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.
