How a tiny electronic component (memory chip) is slowly driving up inflation in India

📌 Summary:

• A single tiny component — the memory chip — common to fridges, washing machines, ACs, batteries, smartphones, laptops, TVs, earphones and pen-drives is exerting upward pressure on India's retail (CPI) inflation
• Cause: the global AI investment boom has pushed chipmakers (TSMC, Samsung, SK Hynix) to prioritise advanced chips for data centres, creating a shortage of DRAM and memory chips used in everyday electronics; manufacturers are passing higher chip costs to consumers
• Data: in May, price indices rose month-on-month for the 7th straight month for laptops/PCs/tablets, 6th for mobiles, 4th for fridges/washing machines/TVs, 3rd for ACs/batteries/headphones; pen-drives and hard disks rose in 15 of the last 16 months (nearing 3% m-o-m)
• Why the CPI impact is still modest: these nine items are only ~1% of the CPI basket (vs ~2% for tomato-onion-potato alone), and electronics makers absorb costs in existing margins, passing them on slower than farmers
• Global signal: US Federal Reserve economists flagged an "unprecedented contribution" to US core inflation from computer software and accessories
• Structural shortage: Counterpoint Research expects global smartphone shipments to fall 14% in 2026 to 1.08 billion (lowest since 2013); LPDDR4 supply may fall over 40% as fabs shift to AI-driven HBM and server DRAM, pushing sub-$150 phones out of the market

📝 Prelims Facts:

• DRAM = Dynamic Random Access Memory; HBM = High Bandwidth Memory (used in AI/data centres)
• New CPI series uses 2023-24 as the base year; the nine electronics items are ~1% of the CPI basket
• Key memory chipmakers: TSMC, Samsung, SK Hynix

🔑 Key Term: Core Inflation — the change in prices of non-food, non-fuel items; increasingly affected by structural electronics price rises.
