Every country has their own laws as far as I know
there should be no "limit" for most countries - just declare it. as long as the source of your money is legitimate you will be alright.
the reporting limit for singapore is > SGD$30k or equivalent (in total, including stuff like traveler's checks, bearer bonds, etc). that amount is about US$24k.
if you're bringing in sums like a few hundred thousand (or perhaps even tens of thousands) dollars in cash for a 1 day stop-over, be prepared to be detained and interviewed.
there are penalties for concealment or non-declaration, of course. the laws are to combat money laundering/criminal financing, not money obtained legitimately and to be spent lawfully.
