Markets Log a Seventh Straight Losing Week as Oil and Yield Pressures Persist

What happened in the markets this week?

Indian benchmark indices extended their losing streak to seven straight weeks. According to Business Standard, the Nifty 50 fell 205.90 points, or 0.88 per cent, to close at 23,140.50, while the Sensex declined 399.22 points, or 0.53 per cent, to settle at 73,895.74 - the longest weekly losing run for Indian equities since the February-March 2020 Covid crash.

The week itself was volatile. A sharp Thursday sell-off was followed by a Friday recovery, with the Sensex adding 315.20 points and the Nifty 77.40 points on value buying in banking, auto and realty shares, according to reports citing Business Standard and Google Finance data.

Among individual stocks, Bharti Airtel, Trent, Infosys, Bajaj Finserv and Tata Motors Passenger Vehicles were among the week's biggest laggards on the Nifty, per NSE-sourced weekly wrap data.

Why did markets fall for a seventh straight week?

Three global factors dominated the week, as reported by multiple financial dailies:

• Elevated crude oil prices. Brent crude remained above the psychologically important $100 a barrel mark for much of the week, driven by ongoing geopolitical tensions around the Strait of Hormuz, a key global shipping route for oil and gas.
• Rising US bond yields. The US 10-year Treasury yield touched multi-year highs during the period, according to reports, which raises the relative cost of capital for emerging markets like India and makes Indian equity valuations look less attractive by comparison.
• Continued foreign investor selling. Foreign Institutional Investors remained net sellers of Indian equities through the week, according to NSE-sourced flow data, extending a multi-week pattern. Domestic Institutional Investors continued to be net buyers over the same period, providing a partial offset.

For an oil-importing economy like India, sustained high crude prices affect the trade deficit, inflation expectations and the rupee, all of which factor into how global investors price Indian assets.

Who is impacted?

• Oil-sensitive sectors: Companies with high fuel or input-cost exposure, and businesses reliant on imported crude derivatives, are more directly affected by a prolonged period of elevated oil prices.
• IT and export-oriented stocks: Reports through the week noted IT stocks under pressure, partly tied to global rate and currency dynamics.
• Retail investors invested in largecaps and midcaps: Broader market participants have seen mark-to-market volatility across large-cap, mid-cap and small-cap indices through the seven-week decline.
• New investors going through their first sustained correction: For anyone who started investing in the last one to two years, this may be among the first multi-week down-cycles they have experienced firsthand.

What should investors understand?

A seven-week decline sounds dramatic in headlines, but it is worth understanding what is actually driving it: this is a market repricing external shocks , not a reflection of a fundamental change in India's domestic economic story.

It is also useful to understand the role Domestic Institutional Investors are playing. According to weekly flow data reported through the period, DIIs have continued net buying even as FIIs sold, acting as a cushion against sharper declines. This is a good, concrete example of why staying invested through SIPs, rather than trying to time entries and exits, allows an investor's own capital to be part of that steadying force rather than reacting to short-term noise.

Tarun’s POV: Seven straight weekly declines may feel unsettling, but market cycles are part of investing. With crude prices, yields and global factors creating pressure, this is a time to stay disciplined and focus on your long-term financial plan rather than reacting to every market move.
