CPI inflation stood at 2.4 per cent in July.
At the same time, stronger food and oil prices are also expected to accelerate wholesale price index (WPI) index to 2.9 per cent in August from 1.9 per cent in July, the global brokerage said in the report.
"As base effects waned, we estimate food inflation of 1.7 per cent year-on-year in August as compared to (-) 0.3 per cent year-on-year in July, which would mark the first positive year-on-year growth print after 3 months of deflation in food prices," Morgan Stanley said.
"Inflation excluding food and fuel should likely remained sticky at 4.1 per cent year-on-year as the impact of the rent house allowance continued to feed through," it added.
Further, the report estimates that the country's current account deficit would widen to USD 11.2 billion (1.9 per cent of GDP) for April-June quarter 2017 from USD 3.5 billion (0.6 per cent of GDP) in the preceding quarter.
However, it noted that CAD would still remain within the central bank's comfort zone.
Going by Morgan Stanley estimates, the trade deficit is expected to narrow to about USD 10.3 billion in August from USD 11.5 billion in July, driven by seasonal factors.
"With higher oil prices and unfavourable base effects, we expect a moderation in both export and import growth on year-on-year basis," the report said.
