one thing to note is that compared to the Singapore dollar, the US dollar has gone down in value tremendously in the past decade plus...
- in recent times, US$1 ~ S$1.2-1.3;
- in the previous decade, US$1 ~ S$1.6-1.8;
- and 2 decades ago, US$1 ~ S$1.6-2.2...
and similarly, the ¥ has strengthened vs. the US$... for Japanese companies, maintaining a consistent pricing in the US for a similar tier of product line means that after conversion to ¥, they are earning less... so, for the Japanese companies, there is the balance of maintaining prices near historical US$ values for competition sake vs the need to maintain ¥ earnings... if you look at US forums and news, there is always news that camera equipment prices are going up... but the Japanese companies are just trying to minimize losses due to the stronger ¥, while on the other hand they can't raise it too much too quickly due to competition... and in the case of HK, the HK$ is tacked onto US$ value, so when US$ goes down, the HK$ goes down by the same amount...
on the other hand, in Singapore, the ¥ and S$ have both been on the uptrend... while Japanese companies thus don't have much pressure to reduce prices, but due to US$ value going down, even if S$ prices are constant, it would seem that the products prices are more expensive than in the US and HK, all else being equal...
