The ASAS will implement enhanced guidelines to regulate advertisements on investments, including investments in overseas properties, and investment services. The enhanced guidelines aim to minimise the scope for advertisers of investments and investment services to make claims that are speculative, misleading or which cannot be substantiated.

The ASAS has updated the media advisory of 20 Oct 2008, following observations and feedback from travel agencies and changes in the industry. 

The Advertising Standards Authority of Singapore (ASAS) has received several concerns on advertisements featuring air sterilizers and alkaline water featuring claims of health and medical benefits.
