<h1>Sovereign Credit Rating Upgraded to Investment Grade Amid Market Volatility and Falling Wholesale Inflation</h1> Stock markets closed largely unchanged after a volatile session as investors awaited the outcome of diplomatic talks between two major countries, which could impact energy markets and sanctions. Key stock indices showed minimal gains with mixed performances among leading firms. A major credit rating agency upgraded the sovereign credit rating of a prominent economy to investment grade for the first time in nearly two decades, citing strong economic growth, fiscal discipline, and effective monetary policy. The agency also noted that potential tariffs imposed by one country on another would have a limited impact due to the latter's reliance on domestic consumption. Inflation data indicated a decline in wholesale prices driven by lower food and fuel costs. Foreign investors sold equities while domestic investors increased their holdings. Global markets showed mixed results, with some Asian indices falling and European markets mostly rising.
