Treasury Yield Stability, National Debt Burdens, and Korea's Relative Room to Maneuver
According to UBS analysis, this FOMC was interpreted as a 'regime change' in the Fed's policy reaction function, seen as a firmer-than-expected commitment to taming inflation, which drove US 10-year Treasury yields lower (to around 4.929%).
The program offered a diagnosis of why markets react so sensitively even to small rate increases across countries: excessive debt levels worldwide. In Japan's case, prolonged delays in structural reform following the bubble collapse in the 1990s have pushed the government debt ratio to 300-350%, making the country especially vulnerable to rate changes.
By comparison, Korea's government debt ratio stands at only 50-60%, giving it relatively greater policy room. However, a comparison was also drawn noting that unlike Korea, which is enjoying record export strength, Japan has limited channels for dollar inflows, making it inherently more sensitive to exchange rate movements.
Two points of interest going forward were identified: the exchange rate and corporate earnings, once the interest rate issue has settled. A further rise in the exchange rate could act as selling pressure on equities, while stabilization could present a buying opportunity; the commentary also emphasized paying attention to companies capable of overcoming rate increases through earnings.
