These listed firms might be under threat from the TPP

Check out the biggest winners and losers under the deal.

Most SGX-listed firms will benefit from the Trans-Pacific Partnership, which will reduce trade barriers and facilitate better flow of capital across twelve key countries. However, some listed companies might face squeezed revenues in the long run on back of increased competition in the local market.

According to CIMB, the biggest losers from the TPP include media and telco companies, and potentially healthcare firms.

This is because innovative tech companies in the media and content space--particularly from the United States, which leads the TPP--could pose a threat for incumbent telcos and media companies.

In the healthcare sector, meanwhile, foreign companies could be interested in medical tourism opportunities here, while extension of drug patents could push up drug costs. 

On the flip side, there is also a long list of potential winners from the TPP, including office landlords, airport services, warehouse operators, manufacturers, and banks.

"Our view is the TPP represents more opportunities for Singapore SMEs to expand out. We are less concerned about the threat of foreign competition coming onshore. Singapore is already a relatively open market for banking, insurance, education, etc. As well, it does not have domestic industries like agriculture or automobiles to protect," CIMB said.
