The AUD/KRW rate closed at 1050.6782 on March 13, marking a daily decline of 0.519%, which signifies a strengthening of the South Korean Won (KRW) relative to a weakening Australian Dollar (AUD). The primary driver for this single-day movement was attributed 85% to the AUD, suggesting broad weakness in the Aussie dollar, while 15% was attributed to the KRW, indicating a slightly firmer stance for the Won.

For those of us following these markets, particularly concerning the economic backdrop, recent geopolitical tensions, specifically escalating conflict in the Middle East which has pushed Brent crude past $100/barrel, are heavily influencing risk sentiment. This environment typically weighs on risk-sensitive currencies like the AUD, leading to its observed weakness. Conversely, the Bank of Korea (BOK) has been holding its policy interest rate steady at 2.5%, maintaining a neutral monetary policy stance to balance growth and financial stability, while the Reserve Bank of Australia (RBA) is under pressure to hike rates due to inflation risks, with market expectations leaning towards a March hike. This divergence in expected central bank paths—potential tightening from the RBA versus a pause from the BOK—could create interest rate differential pressures that favor the KRW over the AUD in the medium term, although the immediate impact seems dominated by global risk aversion.

Examining the trends, the past week saw a modest gain of +0.97% in AUD/KRW, indicating the AUD was stronger overall before this recent dip. Over the 6-month period, the pair has rallied significantly by +13.68%, peaking near the current high of 1056.2766 KRW, suggesting a strong medium-term upward trend for the AUD. The 1-year change confirms this strength at +14.98%. Analysing stability: the 1-week Efficiency (0.47) suggests the market has been somewhat choppy recently, while the 6-month (0.27) and 1-year (0.14) Efficiency metrics indicate a very strong, relatively clean, trending market over the longer horizons. Volatility (SD) has remained relatively stable around 0.5% over the past year, suggesting that while the trend has been strong, daily price swings have been consistent rather than erratic.
