AI read
Global markets are presenting a mixed but generally supportive picture for NIFTY 50's open, with US stock futures showing gains after Wednesday's sell-off, led by tech. Brent crude oil prices have eased slightly to around $89/Bbl after a significant surge, while the Indian Rupee has strengthened against the US Dollar, supported by RBI intervention. However, the Federal Reserve's decision to hold rates has pushed US Treasury yields to 19-year highs, and China's economic growth has slowed, introducing cautionary notes.

MMI 72.2 — Extreme Greed (+2.0 vs prev)

AI read
Indian equity markets are poised for a significant gap-up open, primarily driven by a sharp decline in Brent crude oil prices, which plunged over 6% to trade around $82-$84 per barrel due to de-escalating US-Iran tensions and renewed peace talks. This positive global sentiment is further bolstered by rising US stock futures, with S&P 500 and Nasdaq 100 futures climbing overnight. The Indian Rupee has also strengthened, supported by lower crude prices and a weaker dollar, while the RBI is expected to maintain a neutral stance on interest rates this week.

AI read
Global markets saw a significant positive shift overnight, primarily driven by a sharp decline in Brent crude oil prices, which fell over 5% to around $82-$83.5 per barrel, following reports of easing US-Iran tensions and renewed peace talks. This development fueled a rally in US equities, with the S&P 500 closing 1.5% higher, and also contributed to the strengthening of the Indian Rupee against the US Dollar. Domestically, the RBI's Monetary Policy Committee began its meeting with expectations of a status quo on interest rates, further supporting market stability.

US stock markets surged to record highs overnight, with the S&P 500 gaining over 1.4% on strong AI-linked corporate earnings and optimism for a Middle East peace deal. Concurrently, Brent crude oil prices tumbled by over 5% to below $80 per barrel due to hopes of increased supply and de-escalation of US-Iran tensions. Domestically, the Indian Rupee strengthened against the US dollar, while the RBI is expected to maintain its repo rate. China's manufacturing sector, however, showed a slowdown in July.

The NIFTY 50 is primarily being driven by the Reserve Bank of India's decision to keep the repo rate unchanged at 5.25% and maintain a neutral stance, coupled with an upward revision in GDP growth and a downward revision in CPI inflation for FY27. Positive global cues from rallying Asian markets and easing Brent crude oil prices are also contributing to the bullish sentiment, although some volatility persists due to the new Closing Auction Session mechanism.

AI read
Global markets are signaling a positive bias for the NIFTY 50 open, primarily driven by optimism surrounding a potential US-Iran deal to reopen the Strait of Hormuz, which has sent US stock futures higher and pushed Brent crude oil prices lower. The S&P 500 and Dow Jones Industrial Average hit record highs on Tuesday, extending gains into Wednesday's futures trading. Domestically, the Reserve Bank of India maintained its repo rate at 5.25% for the fourth consecutive time, while raising its FY27 GDP growth forecast and lowering inflation estimates, providing a stable monetary policy backdrop. Brent crude fell to around $78.70/bbl on Wednesday, after significant losses in previous sessions, a positive for India as an oil importer.

The NIFTY 50 is experiencing mixed movements, primarily driven by strong gains in heavyweight Reliance Industries due to positive business developments and easing geopolitical tensions in West Asia. However, the upside is capped by selling pressure in the IT sector, mirroring a broader decline in Asian markets due to AI-related stock corrections. The Reserve Bank of India's decision to hold repo rates provides a neutral policy backdrop.

Global markets present a mixed picture for NIFTY 50's open, despite a bullish GIFT NIFTY signal. Brent crude oil surged to around $82.55/barrel following a Houthi attack in the Red Sea, reigniting supply fears. In the US, the Dow Jones Industrial Average closed at a record high, but the S&P 500 and Nasdaq Composite declined due to weakness in major technology and AI-related stocks. Domestically, the RBI maintained its repo rate at 5.25% for the fourth consecutive time and raised its FY27 GDP growth forecast to 6.7%, providing a positive impetus. Meanwhile, US 10-year Treasury yields rose to 4.66%, indicating tighter global financial conditions.

The NIFTY 50 is trading with a flat to slightly positive bias, primarily supported by gains in heavyweight stocks like Reliance Industries and ICICI Bank. However, the market is experiencing a significant drag from the NBFC sector, notably Bajaj Finance, following the RBI's proposed restrictions on revolving credit facilities. The Indian Rupee has strengthened, while global cues from US futures are mixed and Brent crude prices are higher.

Overnight, global markets presented a mixed picture with US stock futures inching lower and Brent crude prices rising to around $84.46-$84.79 per barrel due to renewed uncertainty surrounding the reopening of the Strait of Hormuz. This follows a strong close for US equities on Friday, where the S&P 500 reached a record high of 7,757.64, gaining 0.6%, as a weaker-than-expected jobs report eased concerns about imminent Federal Reserve rate hikes. Domestically, the Reserve Bank of India maintained its repo rate at 5.25% and upgraded its FY27 GDP growth forecast, while foreign institutional investors continued to inject funds into Indian financial markets.

Overnight, Brent crude prices surged towards $88 per barrel due to escalating geopolitical tensions and uncertainty surrounding the reopening of the Strait of Hormuz, posing a significant headwind for the Indian economy. This was coupled with a rise in US 10-year Treasury yields to 4.71% and a depreciation of the Indian Rupee to 95.28 against the US dollar. US stock markets closed mixed to slightly lower, while China's economic data presented a mixed picture with a Q2 slowdown but some positive high-frequency indicators for July.

This has increased market expectations for a potential Federal Reserve rate hike in September. Overnight, US stock markets closed lower, and Asian markets are trading mixed, while the Indian Rupee has weakened against the US Dollar. China's economic slowdown also adds to global growth concerns.

Overnight read
Overnight, crude oil prices remained elevated due to ongoing Middle East tensions and the effective shutdown of the Strait of Hormuz, posing a significant inflationary risk for India. China's economic growth continued to slow, with Q2 2026 growth at 4.3%, below targets. While US markets saw a positive close on August 12, with the S&P 500 climbing 0.3% on mild inflation data and strong AI stock earnings, and US Treasury yields eased, these positives are likely counteracted by the bearish drivers from oil and regional geopolitics.

Session read
Indian benchmark indices closed on a mixed note, with NIFTY 50 dipping below 24,400 and Sensex down by 100 points, despite positive cues from Asian markets driven by tame US inflation data. Sectoral weakness in Cement and Pharma contributed to the intraday decline, while the MSCI rejig led to significant stock-specific movements.

Overnight read
Overnight, the primary concern for Indian equities remains elevated Brent crude prices, which hovered near $88-$89 per barrel due to ongoing geopolitical tensions in the Middle East, despite a slight dip on August 13th. US markets showed mixed performance, with the S&P 500 gaining 0.3% on August 12th following in-line inflation data that eased immediate Federal Reserve rate hike fears. However, the Indian Rupee depreciated by 12 paise against the US Dollar on August 13th, influenced by weak domestic markets and persistent foreign institutional investor outflows. Domestically, the Nifty 50 closed lower on August 12th, partly due to selling in large-cap stocks.
