The call itself likely won't have any effect. The Philippine market is quite small, and is certainly nowhere near big enough to cause worldwide jitters like the G20 summit did.
The outcome probably could though, but you can't expect it to have the same effect as when big news drop from South Korea or pre-exchange ban China. Bitcoin has been fairly steady during the India and Iran bank bans, so I would guess it will take much more than bad press from a small country to move it.
I agree with you even India could not affect the market, Iran and The Philippines are little players in the industry. They will be only follower of other big counties in the industry which can affect the bitcoin.
