Obligations to hold on to money in contemporary conditions (5)

I believe the answer is:
times
'contemporary conditions' is the definition.
'times' can be an answer for 'conditions' (thesaurus). I'm unsure of the 'contemporary' bit.
'obligations to hold on to money' is the wordplay.
'obligations' becomes 'ties' (I've seen this in another clue).
'to hold on to' means one lot of letters goes inside another.
'money' becomes 'm' (abbreviation used in economics).
'ties' going around 'm' is 'TIMES'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for times that I've seen before include "''For the ..., they are a'changin'''(Bob Dylan)" , "Thunderer?" , "measures the length of something" , "Newspaper - X" , "See 1" .)
