NEW YORK ( TheStreet) -- Copper priced in yen is showing strength as the global economic recovery picks up steam.
Copper is a barometer of economic health because of its industrial use. When the global economy is strong and investment is increasing, more industrial production is needed, which increases the demand for copper.
Over the past few years, however, stimulus has clouded copper's ability to convey true economic strength. Investors see every positive release of economic data as a reason to tighten monetary policy. That causes U.S. dollar strength and commodities priced in dollar terms to experience selling pressure. But when copper is adjusted to be priced in yen, the new pair measures economic health versus a safe-haven currency.
The Japanese currency is bid higher during times of market fear. When market volatility increases, investors sell other currencies in favor of the yen.Therefore, when copper is taken out of dollar terms, it allows for more clarity in analyzing the metal.

The pair has traded range-bound over the past few months, but has recently started to trend higher.
