Crude surge triggers 9% fall in Nifty 50 in 2026; past trends suggest relief once oil cools

Synopsis

Despite a nearly 9% fall in Nifty 50 due to surging crude oil prices in 2026, historical data suggests equities typically recover within two months as oil prices cool. Past instances show Nifty rebounding after sharp oil spikes, indicating a potential for similar recovery as crude prices stabilize.

ET Intelligence Group: Nifty 50 has fallen nearly 9% in 2026 amid fears that surging crude oil prices could weigh on the broader economy. Yet, an ETIG analysis of past instances of sharp oil spikes shows that equities typically recover within two months once crude prices begin to cool.

In July 2008, for instance, crude surged 27% in just two months to a record $147.5 a barrel during the Global Financial Crisis, dragging Nifty down 25%. Two months later, crude had eased 17%, and Nifty rebounded 12%.

A similar pattern emerged in October 2018. As crude rose 18% over two months on strong demand and geopolitical risks, Nifty slipped more than 4%. But over the next two months, the index stabilised while Brent prices collapsed nearly 39%.

but Crude’s impact extends beyond equities

The trend repeated in March 2022 when Russia-Ukraine conflict pushed Brent up 58% in two months and Nifty dropped 11%. Within the following two months, oil prices fell 20% and Nifty regained all lost ground, rising 11%.

Over a 25-year period, Nifty and Brent show a moderately positive correlation of 0.3. A periodic analysis, however, reveals that this relationship has shifted meaningfully over time. The coefficient has declined to around 0.38 since 2020 from 0.87 between 2000 and 2010, indicating a weakening linkage in recent years.

Crude's impact extends beyond equities as higher prices affect input costs thereby affecting the broader economy. The Consumer Price Index shares a strong correlation of 0.64 with Brent, underscoring the effect of energy prices on inflation.

With Brent crude up 72% so far in 2026, the rise is set to increase energy and feedstock costs, potentially squeezing corporate margins and widening the fiscal deficit.
