South Korea’s export price growth rose to 40.8% year on year in April. This was up from 28.7% in the previous period.
The data shows a faster rate of increase in export prices in April. The change equals a rise of 12.1 percentage points compared with the prior reading.
This jump in export prices to 40.8% is a major inflationary signal for us to watch. It puts immense pressure on the Bank of Korea to act decisively at their next meeting in a few weeks. We should anticipate a hawkish pivot, meaning a likely interest rate hike to defend the currency and control inflation.
Given this, the most direct trade is in the currency market. The Korean Won has been weak, recently trading around 1,420 to the dollar, which has helped fuel these export price figures. We should consider buying KRW call options or shorting USD/KRW futures, positioning for the Won to strengthen as the central bank is forced to raise rates.
For equity traders, this suggests a defensive stance on the broader market. Higher interest rates typically weigh on stocks, so we should look at buying put options on the KOSPI 200 index, which has been hovering near the 2,650 level. This provides a hedge against a market downturn caused by tighter monetary policy.
However, we must recognize this price boom is largely driven by the global demand for semiconductors. With the Philadelphia Semiconductor Index (SOX) already up over 20% this year, there is a conflict between strong sector performance and broad macro headwinds. This points to high volatility, making straddles on major tech exporters like Samsung Electronics an interesting play to capture a large price swing in either direction.
Looking back to the rate hike cycle of 2022, we saw how uncertainty around central bank actions dramatically increased implied volatility. We expect a similar environment in the coming weeks. Buying volatility through options before the next Bank of Korea announcement could be a prudent strategy.
