As the credit market continues to tighten, it is clear that major ramifications are already underway. Despite the fact that too many political figures insist that they can do a better job by regulating, in fact the market has a habit of being able to fix its own problems.
Ferrovial, who bought BAA a year and a half ago, are now finding their large debt burden hitting their profits severely.
However, there is a solution: they can simply sell assets.
From the point of view of the consumer, this would be good news. The lack of competition has led to inefficient use of the airports around London. The poor transport links to Heathrow has allowed the BAA owned Heathrow Express to become the most expensive train ride per mile in the world, yet passengers transferring between different London Airports must do so by either coming into London by train, or taking a bus or taxi directly- there is no direct train link.
Breaking up the monopoly would force competition and help to address the costs and the access problems. The invisible hand strikes again!
