Continuously compunded forward rate

Is R(t,S,T) a constant discount rate or just a discount rate.

And why ?

Thanks

Don't understand your question...

$A cpd continuosly at r% for t years: A[e^(rt)]

I assume you're aware of that?

Note that 'r in that equation is a constant. If the OP is asking about compounding where the rate varies over time this formula doesn't apply.

Also a nit to pick, to avoid any confusion - the 'r 'is not a percent, but rather a rate expressed as a decimal. Thus if the interest rate is 10% /year then 'r' would be 0.1 in the formula.

Good point...however, I'm fairly sure the OP will "get the point"; if not:

$2340 @ 3.1% cpd. continuously for 3 years:
2340[2.7183....^(.031 * 3)] = ~2568.06

Try same with daily cpd. instead: you'll get 2568.04; so don't get taken in
by the SOUNDS of cpd. continuously !(Cool)

Thanks for your help but why is R constant?

I'll let E Baines answer that....because I don't see WHY you're asking...
