The regulator has to ensure a level playing field for everyone concerned and also ensure that the integrity of the overall market is maintained
Integrity is a concept of consistency of actions, values, methods, measures, principles, expectations, and outcomes.
To ensure this the regulator has to impose many rules that are unpopular – maintaining integrity of a stock market is a very difficult task.
For example the regulator has to ensure that stockbrokers remain liquid to ensure that they can meet short term liabilities to the stock market as a whole.
What happens if a broker goes bankrupt? Does the central bank bail him out? No – it is the people who had transactions with that broker that suffer. What if you had sold shares and cannot recover sales proceeds you will then lose everything. In that situation we would rightly blame the regulator. It is for this reason that forced selling is in operation to ensure that brokers maintain adequate liquidity to meet liabilities especially during a market down turn – similar to what we are facing now.
Now aren’t you glad there’s forced selling and so many other rules to keep your money safe?
