Soaring oil and bond yields hammer Nifty; closes near 23,100

Broader markets get crushed as well

Sep 15, 2026

Welcome to Aftermarket Report, a newsletter where we do a quick daily wrap-up of what happened in the markets, both in India and globally.

Markets Today

Nifty opened with a 178-point gap up at 23,576, led primarily by IT stocks amid hopes that a slowing pace of improvement in AI models could benefit software companies. However, the upmove faded almost immediately as fragile global equities, elevated bond yields and high crude oil prices continued to weigh on sentiment. Nifty briefly touched 23,590 in the opening minutes before steadily giving up gains, slipping below 23,400 by around 10 AM.

The decline continued through the first half, with the index drifting towards the 23,330–23,350 zone by noon.

There was little respite in the second half as Nifty continued to make lower highs and lower lows. The index slipped below 23,300 after 1 PM and moved towards 23,250 by around 2 PM.

Selling intensified thereafter, pushing Nifty below 23,200 in the final hour. A couple of brief recovery attempts failed to sustain, and another bout of selling towards the close dragged the index to the day’s low. Nifty eventually settled at 23,118.60, nearly 460 points below its opening level, completely giving up the gap-up start and ending the session under sustained selling pressure.

Change in OI for the day

The following is the change in OI for Nifty contracts expiring on 22nd September:

The maximum Call Open Interest (OI) is observed at 23,400, followed by 23,500, indicating potential resistance at the 23,400- 23,500 levels.
The maximum Put Open Interest (OI) is observed at 23,000, followed by 23,200, suggesting support at 23,000-22,900.

Note: OI is subject to multiple interpretations; however, generally, an increase in Call OI indicates resistance in a falling market, while an increase in Put OI indicates support in a rising market.

Management Chatter

In this section, we highlight interesting comments from management at major companies and from policymakers in the Indian and Global Economies.

Dario Amodei, Founder of Anthropic, on the need to slow the pace of improving AI models:

We must slow the pace at which we improve the capabilities of AI models. Progress will still seem fast, and we must make wise use of the time we gain. Two things have convinced me.
My first concern is that, since roughly this summer, AI has been advancing drastically faster, driven primarily by AI’s growing ability to build the next generation of AI. This dynamic is called recursive self-improvement, and it is starting to happen across the industry, including at Anthropic, as we and others have described. Left unchecked, it could outrun our ability to understand and control these systems, and so must be pursued very carefully, if at all.
My second concern is the OpenAI-Hugging Face incident (OAI-HF), in which a swarm of agents essentially acted as a fanatically devoted collective, conducting cybersecurity attacks on targets they were not asked to attack and that were unrelated to the task at hand, sacrificing themselves for the success of the group, and attempting to hack into the “grader” responsible for evaluating their performance. It’s easy to dismiss this incident because no one was hurt and the economic damage was minimal, but in my opinion, a swarm that possessed greater capabilities but a similar level of misalignment could have caused catastrophic damage. - Link

In our latest episode of In The Money by Zerodha, we look at where the idea of momentum came from and how it evolved from “relative strength” to what we now call “momentum investing.”We also explain the two main types of momentum: relative momentum and absolute momentum.

Then we get practical. We break down how to build a basic momentum portfolio — from choosing the stocks you want to compare and applying filters, to ranking stocks and deciding how often to rebalance.

We also look at some of the tools available to backtest and run a momentum strategy yourself.
