A measure to stop the exchange of banknotes for specie (gold/silver). In Great Britain in 1797, it was introduced in response to a gold drain and a run on the banks, beginning a quarter-century era of the "paper pound".

⚠ A suspension is always announced as "temporary". The years it takes to return speak more to the weight of the promise.
