US Intervention in Yen Market Sets Stage for Global Economic Ripples

The US government has intervened in the Japanese yen market to prop up its value, which hit a four-decade low of nearly 164 against the dollar last month. The intervention involved a massive purchase of yen and was coordinated with Japan's finance minister, Satsuki Katayama.

According to estimates by the bank ING, Japan sold around $70-80 billion in US dollars over the last three days to keep its currency from depreciating further. The Japanese government has been selling US Treasury bonds for years to slow down the yen's loss of value, which indirectly affects US interest rates.

Financial analyst Gastón Lentini explained that when Japan buys yen, it sells US Treasury bonds, which drives the price down and pushes up the yield. This can have a ripple effect on the global economy, especially in countries with high levels of debt, such as Argentina.
