SEOUL, December 16 (AJP) -South Korea’s broad money supply (M2) has remained in the 8-percent growth range since August and accelerated further to 8.7 percent in October, the Bank of Korea said Tuesday, while pushing back against claims that the liquidity increase is driving the won’s weakness.
According to the central bank’s monetary aggregates report, the average M2 balance stood at 4,471.6 trillion won in October, up 0.9 percent from the previous month and 8.7 percent from a year earlier, marking the third consecutive month of annual growth above 8 percent.
M2 includes cash, demand deposits and short-term financial instruments such as money market funds and certificates of deposit. The October increase was driven mainly by a 31.5 trillion won rise in securities-related balances, reflecting heavy stock market investment amid a rally in domestic equities. Regular deposits increased by 9.4 trillion won, partly due to banks’ regulatory funding needs.
By sector, households and nonprofit organizations recorded a 24.1 trillion won increase in M2 balances, while other financial institutions and corporations also contributed to the expansion.
Narrow money supply (M1), which includes only cash and demand deposits, rose 0.2 percent month on month and 8.1 percent year on year.
Amid growing debate over whether rapid M2 growth is fueling asset inflation and foreign-exchange volatility, the Bank of Korea said it would revise its monetary statistics in line with updated International Monetary Fund (IMF) guidelines, with revised figures scheduled for release on Dec. 30.
From November data onward, the central bank will publish two versions of M2—the current series and a measure excluding securities-related balances—for at least a year, in an effort to clarify underlying liquidity conditions.
Kim Min-soo, head of the BOK’s financial statistics team, said securities accounted for 3.3 percentage points of October’s 8.7 percent M2 growth, or about 40 percent of the total increase. “Without securities, the growth rate would have been below 6 percent in September,” he said.
The central bank stressed that liquidity alone is not driving housing prices or the exchange rate.
Park Sung-jin, head of the BOK’s market operations team, noted that South Korea’s M2 definition differs from that of the United States, where securities are excluded, cautioning against direct comparisons of liquidity conditions across countries.
He added that recent housing price increases in the Seoul metropolitan area cannot be attributed solely to money supply growth, pointing to macroprudential measures that have slowed household lending.
As for the won, Park said exchange-rate movements are being shaped more by overseas securities investment, exporters’ foreign-currency holdings, and broader capital flows than by domestic liquidity expansion. As of 2:40 p.m. Tuesday, the dollar reversed direction after falling to 1,468 won earlier to 1,475.60 won, up 4.80 won last close on heavy foreign stock selling.
