|---|---|---|
| Raw materials | 9.6% from August | 5 |
| Intermediate goods | −1.7% from August | 6 |
| Capital goods | −2.4% from August | 7 |
| Consumer goods | −2.3% from August | 7 |
What happened
- Raw materials jumped 9.6% from August, led by mineral products such as crude oil, while intermediate, capital and consumer goods import prices all fell.
- On individual items, crude oil import prices rose 21.6%, jet fuel 14.1% and bunker C oil 5.6%.
- The export price index stood at 182.29, a second straight monthly decline after a 3.5% drop.
- Among exports, excavators fell 3.8%, and synthetic fiber fabrics, cosmetics and secondary batteries each fell 3.4%.
Why it matters
- What it costs cost The export-to-import price ratio fell about 2.5% in a month, so each unit Korea sold abroad bought that much less in imports.
- Who's exposed exposure Producers that use imported raw materials meet the oil cost first, and the Bank of Korea says import prices feed production costs and consumer prices along the supply chain.
- What it limits constraint The cushion depends on the won holding: a weaker won would pass more of the dollar rise on to importers, and the non-energy categories would lose the help they appear to be getting.
The 28.1% jump in Dubai crude is a dollar price, and Korean importers pay in won. Dubai crude moved from $88.75 to $113.71 [4] while the won averaged 1,359 per dollar against 1,406.3 in August [3], so a barrel cost about 23.8% more in won terms [13]. The currency took roughly 4.3 percentage points off the dollar move [14]. It also cut the other way: Yonhap reported, citing Bank of Korea data, that export prices fell partly because of the stronger won [10].
That cushion did not stop the index rising. The breakdown beneath the total admits more than one reading: the won explains the falls elsewhere in the basket, softer metal prices explain them, or both do. The other three import categories fell between 1.7% and 2.4% [c6, c7], against a 3.4% move in the won [3]. Inside intermediate goods, the BOK said declines in primary metal products outweighed gains in petroleum and coal products [6]. We think the won is lowering the price of most of the non-energy basket and that raw materials, led by crude [5], are overwhelming it in the total. On that view the claim that energy outweighs currency holds for the aggregate and is untested below it.
The counter-thesis is that metals and goods prices, not the exchange rate, explain the falls, and the published figures do not separate the two. If the won weakens next month and capital goods import prices keep falling, we are wrong.
One month does not repair much. The index fell 4.2% in June, 1.0% in July and 2.2% in August [2]. That is a compounded slide of about 7.2% [16]. After September's rise to 159.37 on the 2020 base [1], the index still sits about 5.7% below its end-May level [17]. The September figures are preliminary [1].
What to watch
- Whether intermediate goods import prices turn up in the October report as petroleum and coal product gains outweigh primary metal declines.
- Dubai crude's October average against September's level, since one month of oil strength has so far recovered only part of a three-month slide.
- Whether export prices fall a third straight month from the 182.29 index level.
