There was in fact no threat of a wider conflict, therefore there was no real danger to the world economy, financial markets, or balance of power. Therefore there was no need for gold to serve as a safe haven. Of course, this could still change if Russia's role in the conflict becomes one of belligerence. Finally, the New York Times article contradicts itself by pointing out that several gold mines have had to shut down due to gold's fall. These figures are only averages.
Many mines operate at much higher costs.
It is becoming less and less profitable to mine gold. That is why many mines have been closed. That is bullish for the price of gold, even though it is bearish for some mining companies. Gold is your financial insurance policy for when all that changes. Right now, you can buy your insurance for the lowest price in 20 years.
