Depends
In general terms, it's always weaker which is shown by inflation. In comparison to other countries, I think it's holding up quite well.
I generally try to hold as little cash as possible. I like having interest bearing or value variant assets that can convert easily to cash. (stocks, bonds, gold, silver, crypto) etc.
Don't get me wrong, it's good to have some cash in savings for emergency, but in reality, hoarding large sums of cash is for suckers.
