The maximum cash limit that Indian travellers can carry abroad is strictly ₹25,000! Did you know that?
Additionally, if you want to carry more cash while travelling, a simple solution is converting the Indian currency to the currency of the country you’re visiting. There’s no cash limit to other currencies like dollars, Euros, pounds etc. when leaving india. Note that, limits may apply, during immigration of the country you’re visiting, so check before travelling and carry cash accordingly.
Also, please note, that you must avoid exchanging currency at the airports because the exchange rates are usually not favourable.
For foreign nations, bringing Indian currency to India is not allowed.
