Switzerland is also a rarity where there isn’t quite a separate head of state (eg UK Monarch, German President) but also the head of government role is done by a council of seven, where the majority decision is what happens. So the legislative body writes the law and the council of seven is tasked with executive power to carry out the law.
The modern Swiss constitution (1848) took inspiration from the American constitution (1789), but rather than a consolidated head of state/government like the American President, they wanted to hew even closer to the long-standing ideals of democracy amongst the Cantons, to also avoid concentrating too much power to individuals. Thus, even though the Swiss Federal Council rotates the title of president every year in turn, it confers zero extra powers.





Interest rate: the percent increase per compounding period . Almost totally useless unless the compounding period is also known.
APR: a metric which extrapolates an interest rate and compounding period out to one year, less any unavoidable fees. Because this metric can be computed for any savings instrument or any loan, it can be used to directly compare rates between different savings or lending institutions.
APR is still computable even for something which won’t last for 1 year (eg a 6-month Certificate of Deposit), for things with a compounding period longer than 1 year, and can deal with promotional offers, such as a savings account that pays 5% for the first 3 months and then returns to a normal rate of 1% ongoing.
Whereas before APR came into existence, it would have been possible to trick people with a seemingly “high” interest rate but it would have a longer compounding period, or they would charge an obligatory “exit fee” that takes a haircut off the interest at the end.
While the law cannot change the mathematical fact that an interest rate must also have a compounding period to be usable, USA law enforces that whenever an APR is given alongside an interest rate, it must have been computed accurately, with large penalties if not.
