>Nothing says "free market" as loudly as "currency manipulation".
It's not currency manipulation. Some currencies are managed more strictly than others. Here's a list of abovementioned currencies:
TWD (Taiwan Dollar) -- Managed float -- Determined mainly by market forces since 1979, but the Central Bank of Taiwan may intervene to prevent excessive volatility.
RMB (Chinese Yuan/Renminbi) -- Managed float -- The People’s Bank of China sets a daily midpoint and allows trading within a narrow band, intervening as needed to stabilize the rate. References a basket of currencies, not just the USD.
EUR (Euro) -- Free float -- Value is determined entirely by supply and demand in the market, with minimal intervention by the European Central Bank.
JPY (Japanese Yen) -- Free float -- Determined by market forces, with occasional intervention by the Bank of Japan to address excessive volatility.
HKD (Hong Kong Dollar) -- Pegged -- Pegged to the US dollar within a tight range via a currency board system; the Hong Kong Monetary Authority intervenes to maintain the peg.
GBP (British Pound) -- Free float -- Determined by market forces, with the Bank of England rarely intervening.
CAD (Canadian Dollar) -- Free float -- Value set by market supply and demand, with rare intervention by the Bank of Canada.
INR (Indian Rupee) -- Managed float -- Primarily market-driven, but the Reserve Bank of India intervenes to curb excessive volatility.
USD (US Dollar) -- Free float.
