The Chancellor of the Treasury (or Chancellor for short), is responsible for all financing of the society. Whilst it is our most specialised role, and therefore least active, the Chancellor has a remarkable impact on the society through their actions. The word Treasury is often accompanied by the Chancellor's role, but all this means is the umbrella term for all the society's finances.
The Chancellor's biggest responsibility is to present an annual budget to the society which consists of binding ways the society is to raise money (including how much membership fees are to cost for the year), how that money is to then be allocated across the society and finally any financial risks that members need to be aware of. The Budget is then put to members to approve or reject. Alongside this, the Chancellor is responsible for approving or denying payments from the treasury that other committee members request, as well as also raising money for charities.
