India is once again scrambling for dollars, kind of begging for them. After spending months defending the rupee, the Reserve Bank of India is now offering generous support to banks to get them to raise foreign-currency deposits. They're being encouraged to get creative with it, everything from creating new products to using new digital channels. And, of course, the old school way of just jacking up the interest rate offer. All designed to get dollars into Indian hands. "Begging" might be a strong word, but only barely.
