This proposal represents one of India's most comprehensive efforts to harmonise its trade policies with major global trading partners.2) Oil Price PlungeOil prices declined by more than $2 on Thursday as discussions around a potential U.S.-Iran nuclear agreement suggested possible sanctions relief, which could boost global oil supply.Brent crude decreased 3.5% to $63.79 per barrel, whilst WTI crude declined to $60.89. The reduction in oil prices assists in controlling inflation pressures and decreases India's import expenses, providing support to domestic market conditions.3) Gold Price DeclineGold June futures on MCX declined to a one-month low of Rs 90,890 per 10 grams, showing a 1.5% reduction from Wednesday's closing price and an 8.5% decrease from its recent high.
