Key Historical Milestones
| Year / Period | Ratio | Event & Context |
|---|---|---|
| Ancient Rome | 12 : 1 | Emperor Augustus legally fixed the ratio at 12:1. Plata was abundant from Iberian mines; gold was scarcer. This ratio held for centuries as the Roman monetary standard. |
| 1792 – USA | 15 : 1 | The U.S. Coinage Act of 1792 fixed the ratio at 15:1, establishing bimetallism. France set it at 15.5:1. This near-geological ratio (Earth's crust: ~17.5:1) was the classical monetary standard. |
| 1873 – Demonetization | ~16 : 1 | The "Crime of 1873" – the U.S. demonetized silver. As countries moved to the gold standard, the ratio began its long-term rise. By 1900 it had reached ~33:1. |
| 1980 – Hunt Brothers | 17 : 1 | The Hunt Brothers attempted to corner the silver market, driving silver to $49.45/oz (Jan 1980). The ratio briefly fell to ~17:1. The CFTC intervened; silver crashed 80% within weeks. |
| 1991 – Gulf War | ~100 : 1 | During the Gulf War recession, silver collapsed as industrial demand fell. The ratio briefly touched 100:1 for the first time in modern history, signalling extreme silver undervaluation. |
| 2011 – QE Era | 32 : 1 | Post-2008 quantitative easing drove both metals higher. Plata outperformed gold massively in 2011, reaching $49.50/oz (historical data, not indicative of future results) – just below the 1980 Hunt Brothers peak. The ratio fell to ~32:1. |
| March 2020 – COVID | 125 : 1 | All-time high. The COVID-19 pandemic triggered a global market crash. Plata's industrial demand collapsed while gold held as a safe haven. The ratio hit 125:1 – the highest ever recorded. |
| 2021 – Recovery | ~65 : 1 | Plata surged on the "Reddit Plata Squeeze" and green energy optimism. The ratio fell from 125 to ~65 within 12 months – one of the fastest ratio compressions in history. |
| 2026 – Today | ~— : 1 | Oro at multi-year highs driven by central bank buying and geopolitical uncertainty. Plata benefits from solar/EV industrial demand but lags gold's safe-haven premium, keeping the ratio elevated. |

Ratio Oro/Plata Hoy — Gráfico en Vivo y Análisis
El ratio oro/plata mide cuántas onzas de plata se necesitan para comprar una onza de oro. Es uno de los indicadores más antiguos y seguidos en los mercados de metales preciosos. Un ratio alto significa que la plata está relativamente barata respecto al oro, y viceversa.
Interpretación del Ratio Oro/Plata
Históricamente, el ratio ha oscilado entre 15:1 y 100:1. La media de los últimos 100 años se sitúa alrededor de 47:1. Durante la pandemia de COVID-19 en marzo de 2020, el ratio alcanzó un máximo histórico de 125:1, señalando una infravaloración extrema de la plata. Los traders suelen usar este ratio para arbitrar entre los dos metales.
What is a historically high Ratio Oro/Plata? ▼
Historically, a ratio above 80 is considered elevated and often interpreted as a signal that silver is undervalued relative to gold. The all-time high was reached in March 2020 at approximately 125:1 during the COVID-19 market crash. The long-term average since 1900 is approximately 47:1.
What does a low Ratio Oro/Plata mean? ▼
A low ratio (below 40) suggests silver is relatively expensive compared to gold, or gold is relatively cheap. In 1980, during the Hunt Brothers silver squeeze, the ratio briefly fell to around 17:1. Investors sometimes rotate from silver into gold when the ratio is very low.
How do I use the Ratio Oro/Plata for investing? ▼
A common strategy is to buy silver when the ratio is high (above 80) and rotate into gold when the ratio is low (below 40–50). This is called ratio trading. However, the ratio can remain elevated for extended periods, and past patterns are no guarantee of future performance. Always consider your overall portfolio and risk tolerance.
Why did the Ratio Oro/Plata spike to 125 in 2020? ▼
In March 2020, the COVID-19 pandemic triggered a global market selloff. Plata, which has significant industrial demand (electronics, solar, EVs), fell sharply as industrial activity collapsed. Oro, as a pure safe-haven asset, held up much better, pushing the ratio to an all-time high of approximately 125:1. The ratio then fell rapidly as silver recovered strongly through 2020–2021.
What was the Ratio Oro/Plata in ancient times? ▼
In ancient Rome, Emperor Augustus fixed the ratio at 12:1. In ancient Egypt it was approximately 2:1, reflecting silver's relative scarcity at the time. The U.S. Coinage Act of 1792 fixed it at 15:1. The natural geological abundance ratio of silver to gold in the Earth's crust is approximately 17.5:1, which is why 15–16:1 was the classical monetary standard used by many countries until the 19th century.
