The gross domestic product (GDP) is the monetary value of all finished goods and services produced within a country in a specific time period. It is also the most common measure of a nation's overall economic activity or the size of economy. More and more economists recognize the flawed character of GDP (for example, it includes only final goods and services; overstates the consumption; it assumes that government spending is productive; it treats imports as something negative; it excludes household work, and so on), but governments, central banks, financial analysts and investors still think it is possible to frame the whole economy in just one number. This is why the GDP growth is still closely followed, also in the gold market.

The literature discerns two channels of GDP's influence on the price of the shiny metal: the income-consumption channel and the safe-haven channel. Let's start with the former. The reasoning goes as follows: when the economy grows fast (as opposed to slowly or declining), people's incomes and purchasing power rise (and respectively: stagnates or decreases), so does the demand for gold. We are skeptical about this alleged relationship, because - as we showed in the July Market Overview - the gold price is not significantly driven by the consumer demand, but by investment demand (consumers are price-takers, not price setters, hence they buy more when the prices decrease and vice versa).

According to the safe-haven channel, GDP indicates the economic health of a country, while gold is a non-confidence vote in the U.S. economy. Hence, there should be a negative correlation between GDP growth and the price of gold. When the economy expands, investment demand (attracted by the safe-haven character of the shiny metal) falls, and vice versa. Let's analyze the chart below, which presents the nominal U.S. GDP growth and the price of gold (we chose nominal, not real growth, because we compare it with nominal gold prices).

Chart 1: Nominal U.S. GDP growth (green line, left scale, year-over-year changes in percent) and gold price (yellow line, right scale, London P.M. fixing) from 1971 to 2015.

As one can see, the price of gold was rising in the 1970s, while GDP growth was declining only during a few years during that decade. In the 1980s and the 1990s, the pace of economic growth was quite high and stable, so gold remained in the secular bear market. In the 2000s, the price of gold was rising both during rises and falls in the pace of GDP growth. And in the 2010s, the shiny metal was again in the bear market, despite the unimpressive economic recovery of the U.S. Although, it seems that there is no clear relationship between gold prices and GDP growth, we shouldn't come to the conclusions too quickly. The chart below presenting the nominal U.S. GDP divided by the price of gold, paints a somewhat different picture. As one can see, the U.S. GDP to gold ratio was negatively correlated with the price of gold: the U.S. GDP in relation to the price of gold was declining in the 1970s and 2000s, and rising in the 1980s, 1990s and 2010s.

However, investors should remember two things. First, GDP is a lagging and often revised indicator. This is why whether the GDP is above or below market expectations (i.e. the surprise component of the news) is more important than the number alone. Whereas, gold (as every currency in general) is a leading indicator, which quickly incorporates investors' expectations about the future outlook. Therefore, gold does a much better job in predicting recession. For example, the price of gold signaled the high probability of the Great Recession as early as in the fourth quarter of 2005, while GDP declined (i.e. the GDP growth became negative) not earlier than in the third quarter of 2008 (officially recession started in December 2007).

Second, GDP is a very aggregate and complex measure of the economic production of a country. The index itself is often not relevant for investors, who are usually interested in comparative analysis between different sectors and asset classes. This is why GDP growth may affect the gold market in completely different ways. Much depends on its trend, sources of its growth (e.g. when GDP is boosted by monetary stimulus or government fiscal deficits, the gold price may also rise) and how it will affect the Fed's actions. Usually, strong GDP growth warrants restrictive monetary policy (this is why sometimes gold prices fell on strong U.S. GDP data), providing this is not a jobless growth. This is one of the reasons why the Fed maintained its unconventionally ease stance (which later turned out to be negative for the gold market), even though the Great Recession ended in June 2009 and overall economic activity exhibited signs of recovery.

To sum up, there is a negative correlation between the price of gold and the ratio of the U.S. GDP to gold price. It makes sense, given the fact that gold is a non-confidence vote in the U.S. economy and a currency competing with the greenback. However, since GDP is a very complex and aggregate lagging indicator, the relationship between these two variables should be taken with a grain of salt.
