The impact of one economic overhaul has rippled on to another in the making. Finance minister Arun Jaitley is now bracing for a delay in wrapping up negotiations to get going on the goods and services tax (GST), with states saying they can’t take back-to-back economic “shocks”. The idea itself doesn’t seem to be in jeopardy, though. It just might take longer and harder to strike a deal with the states, who think they have found a political opportunity in demonetisation to renegotiate the terms. Many who have otherwise been unable to drum up a serious offensive against the Narendra Modi government for triggering a currency shortage are preparing to toughen their stances.
