Mexico will receive at least $6b from its oil hedge deals in 2015, Bloomberg reports. The country locks in its oil price each year through deals with banks to protect against price declines. For 2015, the government of Mexico negotiated a price of $76.40 per barrel, almost $30 per barrel higher than the yearly average.

Mexico sold 228m barrels under these deals, for which the government paid $773m to lock in the $76.40 price. Major banks which will be paying the difference are Goldman Sachs, JP Morgan Chase, Citigroup, Morgan Stanley, BNP Paribas, Barclays and HSBC.

The 2015 payment, due next month, beats Mexico’s previous hedge record – a $5.1b payment received after the 2009 financial crisis. As petroleum sales traditionally account or a third of Mexico’s state-budget, the payment provides substantial breathing-room in a world of low oil prices.
