Macro view
Wholesale inflation
Wholesale price inflation fell to 9.78% in July as food and fuel costs cooled.
This was the first monthly decline under the new 2022-23 base year.
The decline came after wholesale inflation had been rising because of higher global oil prices and supply disruptions linked to the West Asia conflict.
Foreign-exchange reserves
India’s foreign-exchange reserves rose by $14.14 billion to $707 billion in the week ending 7 August.
This followed an increase of $10.51 billion in the previous week.
The increase comes as the RBI and the government use measures to attract foreign-currency inflows.
The FCNR(B) scheme has attracted around $40 billion so far.
Government contracts may move from WPI to PPI
The Finance Ministry has asked ministries and government departments to move from the Wholesale Price Index to the Producer Price Index for price-escalation and adjustment clauses in future government procurement contracts.
The Department of Expenditure sent an office memorandum to all ministries on 13 July.
PPI is more widely used internationally than WPI.
The Commerce Ministry began releasing monthly PPI data for both goods and services in June.
This could allow wholesale price inflation numbers to be phased out over the next five years.
Closing auction trading volumes
Trading activity during the new Closing Auction Session has been much lower than during other parts of the day.
The closing auction began on 3 August.
Between 3 and 14 August, the 3:15 pm to 3:30 pm auction window accounted for only 1.59% of the 1.43 billion average daily shares traded during continuous trading.
By comparison:
- The 9:15 am to 9:30 am opening window accounted for 13.1% of average daily volume.
- The 3:00 pm to 3:15 pm window accounted for 9.55%.
Mint
Average daily volume during the closing auction was 22.89 million shares across 213 eligible stocks.
The analysis used NSE data because the exchange accounts for 93.1% of the cash market.
The session was divided into 25 windows of 15 minutes each, and average volumes were calculated for the 213 eligible stocks over 10 days.
PSB Confluence 2026
The Department of Financial Services is holding PSB Confluence 2026 on Monday and Tuesday in New Delhi.
Nearly 125 senior leaders from public-sector banks and public financial institutions are expected to attend.
Finance Minister Nirmala Sitharaman is scheduled to address the gathering.
The first day begins with discussions on deposit mobilisation and banking for young customers.
Later sessions will focus on helping the investment cycle and global capability centres.
Public-sector bank performance
Public-sector banks reported a record combined net profit of ₹1.98 trillion in 2025-26.

| Deposits | ₹156.3 trillion |
| Advances | ₹127 trillion |
| Capital adequacy | 16.6% |
Mint, 17 August 2026
Growth in lending was broad:
Mint
Deposits rose 10.6% year-on-year to ₹156.3 trillion in March.
Advances grew faster, rising 15.7% to ₹127 trillion.
Inland waterways
The government plans to develop more than a dozen new national waterways over the next five to 10 years.
Investment is expected to exceed ₹10,000 crore.
Cargo movement on national waterways rose from 29 million tonnes in 2014-15 to 218 million tonnes in 2025-26.
This represents a compound annual growth rate of 20.13%.
Mint
Cargo volume has already crossed the government’s 2030 target of 200 million tonnes.
Inland waterways network
The National Waterways Act, 2016, declared 111 inland waterways as national waterways.
Together, they cover around 20,187 km across 23 states and four union territories.
Of these, 32 waterways covering a navigable length of 5,155 km are operating for cargo and passenger movement.
The government has identified another 19 waterways, mainly for cruise tourism and passenger ferries.
Around 85% of existing cargo traffic is concentrated on four waterways:
- NW-1
- NW-91
- NW-100
- NW-10
Electric two-wheeler star ratings
Indian automakers are opposing a government plan to introduce standard energy-efficiency star ratings for electric two-wheelers.
The Society of Indian Automobile Manufacturers has discussed the proposal.
Its members include Hero MotoCorp, Bajaj Auto, Ather Energy and TVS Motor.
The industry view is that electric two-wheelers are not yet financially self-sustaining and still depend on government incentives.
India sold 1.4 million electric two-wheelers in 2025-26, up 20% year-on-year.
Total two-wheeler sales were 21 million units.
Energy efficiency among electric two-wheelers varies from around 2.2 kWh per 100 km to more than 5 kWh.
On 10 August, the Heavy Industries Ministry extended the main electric two-wheeler subsidy scheme until 2027-28.
The subsidy fund was increased by ₹1,000 crore.
LPG production targets
The Petroleum and Natural Gas Ministry has set cooking-gas production targets for refineries for the first time.
The move follows the LPG supply squeeze created by the West Asia war.
A notification issued on 13 August set maximum production levels for 21 refineries and upstream companies.
Their combined production potential is 63,810 tonnes per day.
Reliance Industries’ unit focused on the domestic market received the largest allocation at 18,000 tonnes per day.
Refineries have already increased LPG production to 54,000 tonnes per day from a pre-war level of 36,000 tonnes.
Foreign asset tax amnesty
India opened a tax amnesty scheme on Sunday for small taxpayers with certain undeclared foreign assets.
The scheme is available until 31 December.
Taxpayers with undisclosed foreign income of up to ₹1 crore can use the scheme until 31 December 2026.
They must pay:
- 30% tax.
- An equal amount as penalty.
Taxpayers who acquired foreign assets worth up to ₹5 crore using already-taxed income but failed to report the assets can use the one-time scheme by paying ₹1,00,000.
Parliament’s monsoon session
The Lok Sabha functioned for 17.5 hours during the monsoon session held from 20 July to 13 August.
This was its lowest working time in more than two decades.
The Rajya Sabha functioned for 37.4 hours.
Mint; PRS Legislative Research
Twelve Bills were passed in the Lok Sabha.
Most were passed in less than 15 minutes.
Eleven of the 12 Bills introduced during the session were passed in the same session.
Only 1% of starred questions were answered orally in the Lok Sabha.
The figure was 6% in the Rajya Sabha.
This represented two questions in the Lok Sabha and 16 in the Rajya Sabha.
Dividend payouts and corporate capex
Dividend payouts by BSE 500 companies rose 8.2% year-on-year to ₹5.13 trillion in FY26 from ₹4.74 trillion.
However, dividends as a share of net profit fell to 27.6% from 30.4% in FY25 and 36.5% in FY23.
The FY26 payout ratio was the lowest in 12 years.
The 12-year average is around 35.5%.
Ambit Capital analysed 3,243 listed companies and found that capital expenditure grew at a compound annual rate of 13.5% between FY23 and FY26.
The 10 largest corporate houses accounted for around 61% of listed-company capex.

US retail sales
US retail sales fell 0.6% from the previous month in July.
Markets had expected a 0.1% increase.
June had recorded a 0.2% rise.
This was the first decline since October 2025 and the largest fall since May last year.
The decline came from weaker spending at:
- Online and other non-store retailers.
- Auto dealers.
- Petrol stations.
- Electronics stores.
Euro area trade
The euro area recorded a trade surplus of €8.6 billion in June.
The surplus was €4.8 billion a year earlier.
Markets had expected a €2.2 billion deficit.
Exports increased 14.4% year-on-year to €272.5 billion.
Imports rose 13.1% to €264 billion.
Larger surpluses in chemicals, manufactured goods and food and beverages helped the overall trade balance.
Crude oil
WTI crude moved above $81 per barrel.
It gained almost 5% during the week.
The US increased economic pressure on Iran to reopen the Strait of Hormuz.
Prices were also helped by an International Energy Agency warning that the global oil supply deficit is the widest in five years.

Lebanon experienced its deadliest day of fighting in months as Iran and the US remained stuck in negotiations before the scheduled Monday expiry of their ceasefire agreement.
The Israel Defence Forces said it killed Abu Hassan Alaa, a senior Hezbollah commander, in southern Lebanon on Saturday.
Eleven people were killed in Israeli strikes, including several children.
Strait of Hormuz negotiations
Control of the Strait of Hormuz remains central to the stalled talks between Iran and the US.
Around one-fifth of global oil and gas moved through the strait before the war.
Iranian Foreign Minister Abbas Araghchi said an agreement with Oman would not mean the strait was reopening.
He said those discussions are separate from negotiations with the US.
Brent crude rose almost 6% during the week as several ships were attacked in and around the waterway.
Shipping incidents
Around 65 confirmed incidents involving ships in the Strait of Hormuz were recorded between early March and 11 August.
At least 17 people were killed.
On Saturday, UK Maritime Trade Operations said it had been informed that a projectile had struck the hull of a bulk carrier.
Two Abu Dhabi National Oil Company vessels were hit while passing through the strait on Thursday.
Another was hit on Friday.

Management commentary
“First, AI changes the economics of credit delivery fundamentally. Traditional underwriting relies on financial history – precisely the data that is thin or absent for a new-to-credit borrower, a gig worker, or a small enterprise without formal books. AI models, trained on alternative data – cash flows, GST filings, utility payments, digital footprints – can extend the frontier of “bankable” India considerably further than manual underwriting ever could, at a fraction of the marginal cost per loan. At the same time, AI-enhanced credit risk models, liquidity forecasting, and scenario analysis allow banks – and, indeed, us, as the regulator – to see emerging stress earlier than lagging financial statements permit.”Sanjay Malhotra, Governor, Reserve Bank of India, on how AI can lower the cost of credit delivery
“We saw 24% revenue growth from international patients. Going forward, I expect this momentum to increase—especially with the opening of our hospital in Gurugram, where there is potential for international patients to contribute up to 30% of revenue. Additionally, the opening of the new airport in Navi Mumbai will boost international patient inflows. All in all, the outlook is strong, and we expect to sustain this momentum.”Suneeta Reddy, Managing Director, Apollo Hospitals, on international medical tourism

Feature: The closing auction session
What changed on 3 August
Until the end of July, the closing price of Indian shares was based on the volume-weighted average price of trades completed during the final 30 minutes of continuous trading.
SEBI changed this system on 3 August 2026.
A Closing Auction Session was introduced for stocks with listed derivatives.
How the closing auction works
Continuous trading in eligible stocks ends at 3:15 pm.
At the same time, the exchange calculates the volume-weighted average price from the previous 15 minutes.
This becomes the reference price for the auction.
The auction closes at a random time between 3:28 pm and 3:30 pm. The random close is meant to reduce last-minute order flooding.
Existing open orders are carried into the auction except:
- Stop-loss orders.
- Iceberg orders.
- Orders outside a 3% range on either side of the reference price.
F&O contracts on these stocks continue trading until 3:40 pm.
During order entry, the exchange provides:
- An indicative price.
- Total buy quantity.
- Total sell quantity.
- The order imbalance.
Which stocks are covered
The new system currently applies only to stocks that have derivative contracts.
Other stocks continue to use the earlier VWAP closing-price method.
SEBI says bringing all closing orders into one transparent auction allows buying and selling interest to interact at the same time.
The regulator believes this should produce a more reliable closing price than the earlier system.
The reform also brings India closer to closing mechanisms used by the New York Stock Exchange, Nasdaq, the London Stock Exchange and Hong Kong Exchanges and Clearing.
Gap between 3:15 pm and the official close
One early problem has been the difference between the price visible when continuous trading stops at 3:15 pm and the official closing price around 20 minutes later.
The first two sessions produced unusually large movements during the auction.
The Nifty’s official closing level ended well above its 3:15 pm level.
Nifty and Sensex divergence
Another early issue was the difference between movements in the Nifty and Sensex.
The NSE uses the auction system for eligible F&O stocks.
The BSE continues to use the earlier VWAP system for determining closing prices.
Vinit Bolinjkar, Head of Research at Ventura, described this difference as structural rather than accidental.
He expects the gap to reduce once the BSE adopts a similar system or SEBI introduces common market-wide rules.
Thin liquidity in the auction
Many proprietary trading firms and high-frequency traders initially stayed away from the closing auction or reduced their activity while they studied the new system.
This left the auction with less liquidity than expected.
With fewer buy and sell orders, relatively small transactions could move the equilibrium price more than traders were used to.
A Goldman Sachs note also raised the concern that low participation could allow small order flows to cause large closing-price movements.
Derivatives settlement
The change has had a larger effect on derivatives traders because F&O contracts are settled using the official closing price.
This may differ from the cash-market level at 3:15 pm.
Derivatives prices did not always move in line with the eventual cash-market closing price.
This made it harder for traders to estimate final settlement levels.
Information shown to investors
Brokerages received many questions from clients after the system was introduced.
Some retail investors complained that indicative equilibrium prices during the auction were not clearly visible on several trading applications.
Trader complaints
Within days of the rollout, some traders complained about unfamiliar and sharp price movements near the market close.
A social-media campaign called for a one-day trading boycott.
The campaign was not described as an industry-wide movement.
Possible impact on trading revenues
Zerodha estimated that the change could reduce total brokerage revenue across the industry by 1% to 5%.
Jefferies estimated that a 10% to 20% decline in expiry-day contracts could lead to a 5% to 10% reduction in overall options volumes.
This could also affect the IPO-bound NSE because derivatives trading contributes a significant part of its revenue.
SEBI’s position
SEBI Chairman Tuhin Kanta Pandey said on 12 August that the regulator had not seen evidence of manipulation in the new closing auction.
He described the system as a major market-structure reform that is consistent with global standards.
Pandey asked brokers and other market participants to understand the system and adopt it.
He said similar mechanisms have been used for more than two years in markets including Australia, Europe, the US and Japan.
He also said the auction is useful for passive investors, mutual-fund NAV calculations and index investors.
The earlier closing process carried a risk that late trades could influence the closing price.
SEBI is willing to make changes to the system if required.

SEBI meets brokerages
Senior SEBI officials, including board member KVR Murty, met major brokerages during the first week of the new system.
SEBI described the problems as early implementation issues.
Brokers were asked to:
- Speed up technology upgrades.
- Increase order flow into the auction.
- Improve participation.
SEBI also made clear that the closing auction would not be withdrawn.
Market depth and securities lending
Nithin Kamath argued that the closing auction has exposed existing weaknesses in India’s capital markets rather than creating them.
He pointed to:
- Shallow market depth.
- Limited two-sided liquidity.
- An underdeveloped securities lending and borrowing market.
- Higher trading costs after recent tax changes.
- Tighter institutional funding conditions.

Market participants expect the system to stabilise
Kotak Mutual Fund Managing Director Nilesh Shah said the system may take time to stabilise.
He expects it to become a normal part of the Indian market as participants become more familiar with it.
He said some early problems are normal when a new market system is introduced.
He also noted that closing auctions already operate in many markets globally and that SEBI remains open to feedback and improvements.
Criticism of the rollout sequence
Deepak Sanchety, a retired IRS officer and former chief of surveillance at SEBI, criticised the way the reform was introduced rather than the idea of a closing auction itself.
SEBI had issued consultation papers in 2024 and 2025 and discussed the proposal through its Secondary Market Advisory Committee.
The criticism is that a reform of this size could have been preceded by:
- More mock trading.
- Exchange simulations.
- Broker demonstrations.
- A longer public education campaign.
Securities lending and liquidity
The same analysis raised a sequencing issue.
A successful closing auction requires buyers and sellers on both sides of the market.
Securities lending can help create this liquidity.
India has had a Securities Lending and Borrowing Mechanism for years, but usage remains relatively low.
The analysis questioned whether the securities-lending market should have been developed more deeply before changing the closing-price system.
It also noted that India has unusually high retail participation and a very active equity-derivatives market.
Conditions that make closing auctions work in other countries may therefore not exist in exactly the same form in India.
