Stocks around the world have rebounded from their lows in March: the FTSE-100 is up 10%; the FTSE Eurofirst is up 9%; the S&P 500 is up 8%; and stocks in Japan were up a remarkable 22% at the time of writing.

Does this signal that equity investors and the market more widely is beginning to anticipate the end of the credit crunch? Are there signs, albeit tentative ones, of the debt markets re-opening?

It is difficult to know what the answer is at this point, but certainly CFOs should be wary of being fooled by recent signs of the crunch easing.

The macro economic picture is at best unclear; inflation is increasing sharply, with the retail price index up 0.9% on the month and 4.2% on the year.

Expectations of UK interest rate movements have moved from two cuts over the next year to increasing doubts that we will see further cuts for some time.

Corporate earnings remain relatively strong, 2008 has already seen more defaults across the US and UK than in the whole of 2007, according to S&P, and very few CEOs and CFOs are optimistic of the outlook for their company over the next year.

So where does this leave the debt markets? Capital-constrained banks are seeking equity injections to shore up their balance sheets, which will hopefully bring some liquidity back into the debt markets. Key measures of debt market risk appetite have shown some signs of recovery, and there are also tentative signs that the bond markets are re-opening.

However, a lack of confidence and liquidity in the inter-bank market is wreaking havoc with new debt raisings.

Margin flex language and its subsequent enforcement ­ even for blue chip investment grade corporates ­ is increasingly common, and given the difficulties faced by banks trying to sell down their exposures, CFOs currently raising finance could easily see the spreads they have to pay for debt double, compared with those they could have expected before the summer of 2007.

One thing is certain, for anyone currently at the coal face of raising finance, the repercussions of the credit crunch are still apparent, and could well be for some time to come.
