Basing rights at Singapore, maybe being offered. However given the status of the USN when this would be offered, it actually weakens the US presence in the Pacific. Winston would certainly love the idea of US forces at Singapore, further entangling the US & UK, and also potentially allowing some British forces to move closer to home. Unlike the bases in the Caribbean, Newfoundland, and Bahamas which were close to the US and were seen as improving the position of the US for hemispheric defense, moving forces from Hawaii or the PI, which were US territories, any basing in Singapore before PH would be seen as diverting US forces from US defense to defend European colonies. The isolationist elements would jump all over this, and in this case they would be right as the basing of any US forces in Singapore would only make problems in the Pacific worse.
