The day saw significant domestic economic policy changes and continued international geopolitical discussions. The Goods and Services Tax (GST) Council approved a new two-slab structure (5% and 18%), effective September 22, aiming to benefit the common man by eliminating 12% and 28% slabs, exempting health and life insurance, and setting a 40% rate for luxury goods. This decision dominated late-day economic headlines. Internationally, US-India relations remained a central topic. US President Donald Trump reiterated his criticism of India's tariffs, while also mentioning a "no duty" offer from New Delhi. This occurred amidst a Chinese military parade attended by Putin and Kim Jong Un, which Trump labeled a "conspiracy against the US," though Russia dismissed the claim. India affirmed its intent to acquire more S-400 defense systems from Russia despite US threats, and a US lawmaker criticized Trump's ego for damaging strategic ties. Separately, the Supreme Court discussed Governors' role in delaying bills.
