30 August: on 31 August at 9:30 am, RBI makes the cycle's biggest cash call, holding money 15 days, not overnight.

RBI wants Rs 6,00,000 crore from banks tomorrow morning, and it will keep it for 15 days

RBI announced on Friday 28 August that it will run a 15-day Variable Rate Reverse Repo auction on Monday 31 August. Notified amount: Rs 6,00,000 crore. Bidding is open only from 9:30 to 10:00 in the morning.

The money goes back to banks on Tuesday 15 September. That is the point a treasury desk must mark on the calendar today, not tomorrow.

RBI's own words: on a review of current and evolving liquidity conditions, it has been decided to conduct a Variable Rate Reverse Repo auction on Monday, August 31, 2026.

Through August, RBI ran 21 of these auctions. Almost every one was for a few days at a time, which let banks decide again each morning. A 15-day bucket takes that daily choice away.

Why it matters: For fifteen days your bank cannot change its mind about the cash it parks tomorrow. Whatever your desk bids at 9:30 in the morning is locked till 15 September, so the call has to be made before the window opens, not inside it. If your bank has any payout, any large maturity or any month end need before the middle of September, that money must be kept out of tomorrow's bid.

American regulators tell examiners to look at what actually breaks a bank

On 27 August the Office of the Comptroller of the Currency and the Federal Deposit Insurance Corporation issued a final rule to focus examiners and institutions on material financial risks. On the same day the OCC said it will make its own supervisory findings and enforcement actions clearer and more consistent, and the FDIC approved an interim final rule on reciprocal deposits. The direction of travel is the same one Indian bankers have watched since the RBI supervisory reset: fewer scattered observations, more weight on the few things that can sink the balance sheet.

Looking back: The record put straight first, because you are owed it. The briefs for 24, 25 and 28 August were handed to our mail service, and it delivered none of them to a reader. The edition for 29 August was written but held back by our own rule, because one of its ten parts was empty, and a half written brief is worse than none. Today's edition goes out on a different route, one that has delivered 21 out of 22 mails in the last seven days. That is our failure, printed here, and this is the fix.

Watch next: Three things to watch this week. One: how much of tomorrow's Rs 6,00,000 crore banks actually hand over, and at what cut-off rate. Through August the answer has been between 35 and 71 paise of every rupee asked, and the price has not moved off 5.24%. Two: Wednesday's Rs 30,000 crore bond buyback, which puts cash back two days after RBI takes it away. Three: whether any further co-operative bank comes under Section 35A directions after Friday's order on Ahmednagar.
