01Intuition

Build the mental model first.

Forward points compensate for the interest-rate differential, not an expected spot move.

ONE-LINE DEFINITION

A future exchange rate implied by two funding curves.

02Mathematics

Now make it exact.

F0,T=S0e(rdrf)TF_{0,T}=S_0e^{(r_d-r_f)T}
Notation and units

Decimal rates and volatilities, year-fraction time and continuous compounding unless stated otherwise.

03Assumptions

Every model has a price.

01

Educational conventions are stated explicitly and may simplify market quotation or settlement details.

02

Rates are continuously compounded unless the section says otherwise.

03

Inputs are deterministic in the base model.

“An unstated convention is a future reconciliation break.”— THEQUANTBATEMAN
04Market use

Why a quant cares.

Hedging, carry, basis analysis and option forwards.

FRONT OFFICE VIEW

The hedge has opinions.

Start with the quote convention, then ask which FX risk survives the hedge. A number without its convention is merely well-dressed ambiguity.
