Platinum Price in the 1970s

Platinum entered the 1970s trading freely at about $112 per troy ounce in 1971, and for the first half of the decade its path was gradual rather than dramatic. The price climbed to $119 in 1972 and jumped to $150 in 1973 as the first oil crisis pushed up costs across industry and lifted demand for the metal in refining, glass and chemical production. Momentum carried it to $175 in 1974, but the metal then cooled with the global recession, slipping to $163 in 1975, $153 in 1976 and recovering only modestly to $158 in 1977. For much of the mid-decade, platinum simply drifted, tracking the broader industrial slowdown that followed the 1973 to 1974 shock.

The real acceleration came at the end of the decade. Platinum surged to $260 in 1978 as a new and structural source of demand took hold, then nearly doubled again to $445 in 1979. That final leap coincided with the second oil crisis, triggered by the Iranian Revolution, which more than doubled crude prices and sent investors piling into gold, silver and platinum as inflation hedges. Between the 1971 open near $112 and the 1979 close near $445, platinum rose roughly 297 percent, with the bulk of the gain compressed into the last two years of the decade.

The deeper story of platinum in the 1970s is the birth of automotive catalytic-converter demand. The 1970 US Clean Air Act required emissions of carbon monoxide, hydrocarbons and nitrogen oxides to fall sharply, and to meet the 1975 model-year standards automakers fitted catalytic converters beginning in the autumn of 1974. Those converters relied on platinum as the active catalyst, and as the technology spread across the American fleet, carmakers moved to secure and stockpile supply. This transformed platinum from a niche industrial and jewelry metal into one tethered to global auto production, a shift that explains why the price broke out to $260 in 1978 even before the oil shock.

On top of this structural demand came a macroeconomic spark. The 1979 oil crisis, following the Iranian Revolution, unleashed a wave of inflation fear that lifted all precious metals, and platinum rode that wave to $445. The combination of a new, hard-to-substitute source of consumption and a speculative flight to hard assets set the stage for the metal's even more extreme spike into 1980. The decade therefore marks the moment platinum's modern demand profile, dominated by emissions catalysis, was established, laying the groundwork for the automotive-driven cycles that would define its price for decades to come.
