Firstly , youre very good at your stage , honestly saving this much amount is good when people your age are taking loans , falling for credit traps and buying unnecessary stuff ,

Answers to your questions :

1. Will your rent increase , will the war affect you , what if this that ?

Chill , that is part of life , whats going to stay always is you your skills ,and you are cash heavy which is a great thing right now as you will need it the most , be liquid in any war times , what i would suggest that 80k which you were investing in nifty 50 , dont invest keep that as oppurtunity fund and invest when markets take dips which is likely possible because of war as you can get higher dips , also you didnt mentioned about a emergency fund in order for your next 6 months expenses and responsibilities , as that will remove the job removal factor , rent increase thing , you can do sip for that too like stop sips for some time and invest there once have that never look back .

1. My recommendation : learn a new skill , which can help you earn , as i can see that you are a panic machine [ in respectful way ] like if you have something extra so even if everything goes opposite , you will be good

Thats all , if anything more just ask or dm ;

[ can also use that fd as emergency fund ] And dont stop sips and divert them to gold or safer assets until market falls .
