AI sell-off rattles global markets as Putin-Trump rift deepens and UK fiscal credibility comes under scrutiny

Valuation compression in AI-linked equities is particularly consequential because the sector has attracted enormous passive-fund inflows, meaning a sell-off is amplified across index-tracking portfolios worldwide. The Nasdaq's 2.2% single-day drop is the kind of move that triggers margin calls and forces leveraged funds to liquidate positions across asset classes, spreading volatility beyond tech itself.

For India, the read is mixed. Indian IT services exporters — Infosys, TCS, Wipro — derive a significant share of revenues from US tech-sector clients; a prolonged AI spending slowdown would weigh on their order books and drag on the Nifty IT sub-index. However, Wednesday's early data showed the Sensex and Nifty partially recovering, supported by softening crude oil prices, which reduce India's import bill and ease pressure on the rupee. The rupee nonetheless slipped 10 paise to 94.86 against the dollar in early trade, reflecting residual risk-off pressure.

Geopolitical risk premium in energy markets had been partially deflated by hopes of a Ukraine settlement; a visible Trump-Putin rift re-introduces uncertainty. European gas storage levels and LNG import contracts will be watched closely heading into winter planning season. Defence stocks in Europe, which have surged since 2022, may see renewed buying interest if the diplomatic outlook darkens further.

India's exposure is real but indirect. India has been a major buyer of discounted Russian crude under the shadow of Western sanctions; any escalation that tightens the sanctions regime or disrupts Russian export logistics would raise India's effective oil import cost. Conversely, India has carefully maintained diplomatic neutrality, and a prolonged US-Russia estrangement could actually expand New Delhi's strategic leverage as both sides court its alignment.

Bond vigilantes — a term coined in the 1980s to describe investors who sell government bonds to punish profligate fiscal policy — are particularly potent in the UK because the government relies on continuous gilt issuance to fund its deficit. A sustained rise in gilt yields raises debt-servicing costs, squeezes the fiscal headroom the Office for Budget Responsibility grants, and forces spending cuts or tax rises that offset any stimulus the borrowing was meant to provide.

For India, the UK's fiscal credibility story is a useful mirror. India's own fiscal consolidation path — targeting a deficit of 4.4% of GDP in FY26 — is watched closely by FII/FPI investors in Indian government bonds, which were added to JP Morgan's EM bond index in 2024. Any global repricing of sovereign risk, triggered by a UK gilt sell-off, could spill over into emerging-market bond spreads and put upward pressure on Indian 10-year yields, complicating the RBI's rate-cutting cycle.

Inventory-led PMI rebounds are a well-documented statistical artefact: firms restock shelves after a demand shock, temporarily lifting output indices, but the bounce fades quickly if consumer or business spending does not materialise. The fact that this rebound coincides with near-record job cuts suggests firms are cutting costs even as they rebuild stock — a sign of deep uncertainty about the demand outlook, likely linked to ongoing US tariff policy and global trade fragmentation.

India's manufacturing sector, which has been a relative outperformer in the EM universe, could face headwinds if US import demand softens materially. Indian exporters of textiles, engineering goods and pharmaceuticals to the US market would feel the pinch. However, a weaker US growth outlook that prompts Fed rate cuts would also ease dollar strength, potentially providing relief to the rupee and reducing India's external financing costs.
