That inventory-versus-input-cost tension becomes clearer once the upstream chemical picture is laid out. Acrylonitrile, the principal feedstock behind acrylic fibre, has risen ** per cent since late July, from $*.*** per Kg to $*.*** per Kg on a CFR Southeast Asia basis till August **, as regional cargo availability tightened and buyers moved early to secure supply. Propylene has climbed almost as sharply, gaining ** per cent on a CFR China basis (from $*.*** per Kg to $*.*** per Kg) and ** per cent on FOB Korea terms (from $*.*** per Kg to $*.*** per Kg), with cracker operators shifting cost burden onto buyers rather than compressing already-thin margins further.
Caprolactam, the direct input feeding into the nylon numbers above, has increased * per cent, from $*.*** per Kg to $*.** per Kg on an FOB China basis, whilst Benzene has added * per cent, moving from $*** per Kg to $*,*** per Kg FOB Korea, supported by firm downstream aromatics demand. Mono ethylene Glycol has been the second-sharpest mover in the basket at ** per cent, climbing from $*.*** per Kg to $*.*** per Kg FOB China, a jump linked as much to depleted port stock in China as to broader cost inflation. Purified Terephthalic Acid has stayed comparatively steady, up just * per cent from $*.*** per Kg to $*.** per Kg FOB China, reflecting a more comfortable supply position relative to its peers.
Underpinning nearly all this movement is the crude oil market, which has spent the past month in a state of elevated tension rather than settling into any clear direction. Brent, trading around $** per barrel on July **, spiked as high as $*** per barrel within two sessions before retreating into the high, reached the low-$** per barrel by early August, and has since climbed back to $** per barrel its strongest reading in four weeks. WTI has followed an almost identical path, swinging from $** per barrel up to $** per barrel, down to roughly $** per barrel, and back up to $** per barrel.
This volatility is being read by traders as a direct consequence of hardening tension between the US and Iran, with market sources indicating Washington is preparing a tougher sanctions package intended to significantly restrict Iran&#**;s economic output. Because no negotiation channel currently appears active, participants are treating the disruption as an extended risk factor rather than a passing spike, and that expectation is keeping a premium built into crude pricing that continues to filter into every link of the textile feedstock chain.
Looking ahead, the trajectory of US-Iran relations remains the single largest variable for the textile raw material complex. Confirmation of tougher sanctions, absent offsetting supply from elsewhere, would likely keep crude and consequently acrylonitrile, propylene and MEG under sustained upward pressure through the rest of the quarter, with acrylic staple fibre and polyester yarn, both currently lagging their input costs, most exposed to a delayed catch-up in pricing. A cooling of tensions, on the other hand, would likely see the fastest correction in the chemicals that have run up hardest, acrylonitrile and MEG in particular. Buyers across PSF, NFY and ASF categories are advised to build this uncertainty into near-term procurement planning rather than assume current levels will hold.
