October Stock Market Crash Wipes off ₹675 lakh Crore Globally, More Wealth Than India and Japan’s Combined GDP

A brutal, synchronized liquidity withdrawal across global trading floors has wiped out an astounding $7.12 trillion (₹675 lakh crore at present dollar conversion rates) in investor wealth through late October. As markets locked in their final monthly figures on Friday, hard exchange data confirmed that the cross-border stock rout has destroyed a sum larger than the entire annual economic output of Japan ($4.2 trillion) and India ($3.7 trillion) put together.

What began as an isolated valuation correction in Silicon Valley has mutated into a broad-based contagion, hitting emerging markets across Asia and stripping liquidity from major exchange order books.

Wall Street’s $2.15 Trillion Tech Meltdown

The epicentre of the crash remains Wall Street, where the Nasdaq Composite plummeted to 25,592.48 to seal October with a staggering $2.15 trillion aggregate loss across tech listings. Skepticism over aggressive artificial intelligence capital expenditure triggered massive panic, as investors demanded immediate revenue conversion that mega-cap balance sheets failed to show.

Alphabet led the downward spiral, shedding over $500 billion in market capitalization after quarterly expenditure outstripped monetization metrics. The sell-off quickly spilled over to Amazon, Meta, and Intel, dragging the broader American equity market into a single-session $1 trillion bloodbath.

Greater China Equities Dragged Down by Deflationary Squeeze

Across the Pacific, Greater China markets sustained the single largest territorial hit, shedding $3.10 trillion across Mainland bourses in Shanghai and Shenzhen alongside Hong Kong’s Hang Seng Index.

Aggressive domestic price wars combined with persistent consumer deflation forced forward price-to-earnings ratios down to multi-year lows. Heavyweight technology firms and industrial battery manufacturers took the brunt of the damage, prompting massive institutional foreign capital flight out of Chinese equities.

South Korea and India Suffer Sharp Capital Outflows

In Seoul, the KOSPI slid into official bear market territory—trading down 31 per cent from its June peak. A single-day 3.2% plunge sent the benchmark down to roughly 6,420 points, wiping out ₩162.67 trillion ($108 billion) in one morning session and bringing monthly losses to $380 billion (₩510 trillion). Semiconductor heavyweights Samsung Electronics and SK Hynix accounted for more than 60 per cent of those losses as international funds dumped hardware exposures.

Indian markets faced an equally intense shakeout as Foreign Institutional Investors (FIIs) unleashed a historic selling spree. The aggregate market capitalisation of all companies listed on the Bombay Stock Exchange (BSE) contracted by ₹43.2 lakh crore (~$520 billion) over the month. A combination of stubborn global crude oil prices, high US Treasury yields, and earnings compression across large-cap IT exporters and consumer blue-chips drove steady wealth erosion across Dalal Street.

Circuit Breakers Hit Jakarta as Contagion Spreads

Southeast Asia provided no safe haven. Indonesia’s IDX Composite crashed 14.91% in a single week to hit 5,185.10, stripping $110 billion (Rp 1,720 trillion) off Jakarta’s main board.

Triggered by MSCI’s proposal to review Indonesia’s index classification, alongside rapid depreciation of the Rupiah, rapid foreign dumping repeatedly tripped market-wide circuit breakers as over 800 listed stocks ended in the deep red.

An additional $860 billion evaporated across European and secondary global markets, largely driven by high US bond yield pulls and general risk aversion.
