A garment is mostly fiber, and in 2026 fiber got expensive on both sides of the shelf. Cotton surged on drought and restocking, while polyester β long the cheap hedge β rose in lockstep with crude oil. For the first time in years, mills could not simply swap one for the other to protect margins. The result is a quiet cost squeeze that travels from the spinning frame to the price tag.
Cotton's weather-driven rally
Global cotton prices climbed to about 92 cents per pound in May 2026, up from 74.5 cents in January, according to retail fabricθ·θΈͺ data. On China's Zhengzhou exchange, cotton futures pushed past 16,000 yuan per ton to a near one-year high as heat across major growing regions fed aεδΊ§ expectation. The US Cotton Belt and India's Gujarat both ran dry, and speculative money poured in β one session in April absorbed more than 1.5 billion yuan of fresh positioning. Cotton Incorporated's June 2026 Executive Cotton Update noted the New York nearby contract averaged 81.7 cents per pound in May and the Cotlook A Index sat at 92 cents, with garment CPI rising more than a full point in both February and March.
Polyester lost its cheap advantage
For decades, when cotton spiked, mills shifted toward polyester blends. That cushion broke in 2026. Polyester staple fiber averaged 8,814 yuan per ton in mid-September, up 5.44% week-on-week, and purified terephthalic acid (PTA) β a core feedstock β rose more than 30% as Brent crude jumped over 85% in the first quarter. Because polyester is a derivative of oil, its cost moved with cotton instead of against it. The narrowing spread removed the easy margin play, and mills had to manage exposure across both streams through staggered buying rather than a simple material swap. Recycled polyester held steadier, cushioning some budgets against feedstock swings.
Why fabric costs move before retail prices
The lag is the part shoppers don't see. Cotton-dominant apparel cost an average of $3.67 per square metre in April 2026 β down 0.5% year-on-year but still 9.3% above the pre-tariff three-year average, Cotton Incorporated reports. Yarn and fabric makers absorb the first hit, then finished-goods brands negotiate terms, then retail prices adjust a season later. India's textile and apparel exports still grew 2.1% in fiscal 2026 to about $35.8 billion, partly because the government exempted raw cotton imports from an 11% duty between June and October 2026, letting exporters access cleaner long-staple fiber without extra cost. That kind of policy cushion is the exception, not the rule.
What the squeeze means for the clothes you buy
When both natural and man-made fibers climb together, brands face a choice: absorb the cost in margin or pass it through on differentiated product. At PHEFEE we lead with fabric transparency β every dress listing states its composition (for example 95% polyester / 5% elastane or 100% cotton) and its inch-based sizing, so the spec you read is the spec you wear. Our new-in edit favors blends that hold shape and color through repeat washes, which matters more when fiber costs are volatile and quality is the only durable hedge. A garment that lasts 50 wears is cheaper per wear than a $12 top that pills after three.
How brands actually hedge the squeeze
The brands that protect shoppers from whipsaw are the ones that buy like manufacturers, not like merchants. Forward contracts lock cotton or polyester at a fixed price months before a garment is cut, so a 30% feedstock move never reaches the tag. Blend ratios shift deliberately β more recycled content when virgin polyester spikes, more cotton when the opposite happens β and deadstock programs reuse mill overruns instead of ordering fresh fiber at a peak. At PHEFEE we favor small, planned runs in stable neutrals over chasing trend fabrics, which is why a core knit rarely jumps in price between seasons even when the raw market is volatile.
Frequently asked questions
Why did cotton prices rise in 2026?
Drought across major producing regions β the US Cotton Belt and India's Gujarat β cut new-crop expectations, while global buyers restocked aggressively and speculators added positions. Cotton reached about 92 cents per pound in May 2026, up from 74.5 cents in January.
Why did polyester get more expensive too?
Polyester is made from oil-derived feedstocks (PTA and MEG). With Brent crude up sharply in early 2026, those feedstocks rose more than 30%, so polyester could no longer act as the cheap alternative to cotton. Both fibers climbed together for the first time in years.
Does higher fiber cost mean higher clothing prices?
Eventually, but with a lag. Mills and brands absorb the first hit, then retail prices adjust a season later. Cotton-dominant apparel ran about 9.3% above its pre-tariff three-year average cost by April 2026 even as headline garment CPI moved more slowly.
Is recycled polyester affected by the oil spike?
Less so. Recycled polyester is decoupled from virgin feedstock costs and held steadier through 2026, which is one reason many brands shifted blend ratios toward recycled content to lower sensitivity to crude-oil swings.
