Once interest and dividends exceed 20 million won a year, the excess is taxed at progressive rates. But a comparative-taxation rule keeps the effective rate at 14% up to roughly 81 million won for people with no other income. Health insurance moves first.
A bond ETF with a duration of 17 years loses roughly 17% when rates rise 1%p. Korea's 30-year government bond yield rose 1.459%p this year — and the ETFs tracking it fell 25.39% on average. Here is the arithmetic behind that.
Korea taxes overseas stock gains above 2.5 million won at 22%. Because the base is won-converted at settlement-date rates, an account down 5% in dollars can still owe 1.9 million won.
