Indian stock markets rose sharply on Tuesday's opening session after US President Donald Trump declared a cease-fire between Israel and Iran, providing some respite to global investors despite recent geopolitical tensions.

The benchmark Nifty 50 index began higher at 25,179.90, up 208 points or 0.83 percent. The Sensex began strongly at 82,534.61, up 637.82 points, or 0.78 percent.

According to experts, with tensions between Israel and Iran easing, investors are now turning their attention to impending global events that may have an impact on markets. One of the crucial dates on investors' radar is July 9, the deadline for US tariff determinations. If tariff fears are postponed or handled, the markets may resume their upward path.

Ajay Bagga, Banking and Market Expert told ANI "The geopolitical storm seems to be ending as President Trump announces Israel-Iran ceasefire. Markets have started chasing the proverbial rainbow just beyond the horizon. Crude oil made the biggest move, with the entire USD 10 risk premium embedded being shattered in a swift move downwards. Global stock markets are cheering the cessation of hostilities. Dollar is down, Gold is down and risk on moves are evident in soaring markets".
