In which case, how much could you lose?
To answer these questions and understand why a collapse in the US sub-prime mortgage sector is sending shockwaves around the globe, we need to appreciate the factors that have come together to create this crisis.
Firstly banks have been making increasingly risky loans by throwing cash at the sub-prime sector.
Defaults have risen as the low rates have ended, and rising interest rates and unemployment levels have done nothing to slow them.
In itself this would not be enough to cause a wider crisis. But, firstly, there has been a trend in financial markets towards taking on increased risk at apparently lower rewards.
And secondly, due to the repackaging of mortgage lending, no one really knows who is carrying the financial risk of sub-prime loans.
Financial institutions have lost confidence, not only in their traditionally higher risk clients, but also in each other.
So should the UK construction industry be worried?
Objectively, the net impact on the global economy should be limited in the UK house prices have continued to increase and interest base rates have risen by only 1 per cent in two years.
But less credit-worthy firms and individuals will find it much harder to borrow at affordable rates which impacts both contractors and developers alike.
Indeed, on high value schemes we are already finding some developers are struggling to find debt at the right price, or to find it at all.
Now that the debt markets have scaled back we might find that merger and acquisition activity falls in the final quarter of 2007 only to explode again in the New Year when the debt markets start with a clean sheet.
So while there may be losers in the financial sector, the construction and house building sectors are well placed to weather the storm.
