Why a big slump in South Korea s exports matters

The steepest on-year drop in trade since 2009 is a mark of sagging global

demand

Sep 1st 2015 | SEOUL

NEW trade figures from South Korea on September 1st surprised even the

gloomiest of economic forecasters. The country s exports shrank by the largest

annual amount in six years, down 14.7% last month from a year earlier to under

$40 billion, according to the ministry of trade, industries and energy. Few

analysts had expected more than a 6% drop: though exports have dropped every

month since January, they declined just 3.4% in July in annual terms. Morgan

Stanley, an investment bank, tempered its growth forecast for South Korea down

to 2.3% from 2.5% for the year.

Exports account for roughly half of South Korea s GDP and a quarter of all

those go to China, its biggest trading partner. South Korea has been struggling

with the rise of its currency, the won, against the Japanese yen in key export

markets; now China s successive devaluations have started to bite. Provisional

figures released today showed that South Korean car shipments dropped steeply

in August, by nearly a third. Though exports of smartphones rose, fast-rising

Chinese handset makers are increasingly vying with Samsung Electronics of South

Korea for global market share (its profits have dropped for five consecutive

quarters). A weaker yuan is also keeping holidaying Chinese shoppers away just

as the country attempts to woo them back after an outbreak of Middle East

Respiratory Syndrome (which infected 186 and killed 36) hit South Korea in May.

Low global oil prices are also behind the startling figure. Petroleum products

are a key South Korean export, and their price has dropped by over 40% from

last August. The ministry of trade today pointed to this distortion to downplay

concerns that falling exports might presage serious weakness in the domestic

economy; by volume, it said, total exports actually grew by 3.8% in August from

a year earlier. The ministry also argued that local manufacturers ought to be

more profitable given the lower cost of importing raw materials. Only last

month the finance minister, Choi Kyung-hwan, argued that a weak yuan could be a

boon: if Chinese exports increased, so too would demand for intermediate goods,

such as electronic components, which make up the bulk of South Korea s exports

to China.

Market watchers are less sanguine. Frederic Neumann of HSBC, a bank, says the

plunge is pretty serious , not least because South Korea has long been a

reliable bellwether for global trade. South Korean manufacturing sits at the

top of the production chain, he says: a big chunk of its exports do indeed go

into other finished goods, like Chinese smartphones and American laptops. But

if demand slows there, so do requests for chips and screens. That means that

Korean macroeconomic data picks up very early changes in the global industrial

cycle . Neither is a slowdown in China the only source of export weakness;

South Korea's exports to the euro area plunged by 21%, more than twice the

decline in exports to China.

Recent figures show that the economy expanded by a feeble 0.3% from April to

June compared to the previous quarter: its weakest gain since 2009. The

government has already cut its growth target from 3.8% to 3.1% since January;

for its part the Bank of Korea has been cutting its key interest rate, now down

to an all-time low of 1.5%. Ever more analysts expect South Korea's central

bankers to shave it again soon, and perhaps even as early as next week, when

they gather for a policy meeting on September 11th. If South Korea's bellwether

status is anything to go by, central bankers elsewhere ought to be paying

attention as well.
