PSA may already have been a monopoly. And given PSA's already huge market share and SGC's small share, change in market concentration may not be that great as a result of the deal. For a quick test add up the sum of the squares of their market shares before and after. This is called the HHI Index and is one tool used by the government. It's been a while since I've done this so would need to remind myself how to interpret the results. You also have to consider entry barriers not just existing market structure.
