Financial regulators may want to see an increasing amount of trading occurring in different ways for various reasons:

1. Privately, between individuals and firms: This type of trading is often less regulated and can be more flexible. It allows for direct negotiation between parties and can be tailored to specific needs. However, it can also be less transparent and more risky, as there is less oversight and protection for the parties involved.

2. Over organized unilateral trading facilities: These are platforms where one party (usually a large financial institution) sets the terms and conditions for trades. This can provide more security and predictability for traders, as the terms are set by a trusted entity. However, it can also limit competition and potentially lead to unfair trading conditions.

3. Over organized multilateral trading facilities: These are platforms where multiple parties can trade with each other under the same terms and conditions. This can increase competition and transparency, as all parties have access to the same information and can negotiate on equal terms. However, it can also be more complex and difficult to manage, as there are more parties involved.

In general, financial regulators may want to see a balance of these different types of trading, to ensure that the financial market is competitive, transparent, and fair for all participants.
