(Bloomberg) -- Precious metals led commodities higher, boosting mining stocks, on speculation central banks in some of the world's leading economies will step up monetary stimulus in the wake of Britain's decision to leave the European Union.

Silver touched a two-year high and gold rallied for a fourth day after the Brexit vote spurred demand for havens. Brent crude held above $50 a barrel as Nigerian militants threatened more supply disruptions, while nickel climbed to an eight-month high after the Philippines announced plans to audit mining operations. Miners in the Stoxx Europe 600 Index gained while automakers and builders fell. Currencies of commodity producers were the best performers. The Ibovespa rallied to an eight-week high in Sao Paulo.

Gold and other raw materials have advanced on speculation the U.K.'s June 23 vote to leave the EU will trigger further stimulus from the European Central Bank and Bank of Japan while reducing the chance that the Federal Reserve will raise interest rates this year. Global equities last week rallied by the most in four months as policy makers worldwide sought to reassure investors they would take steps to limit the economic fallout of so-called Brexit and ensure financial markets kept functioning. The securities tumbled by the most since 2008 on the day after Britain's referendum.

"Investment demand for metals continue on expectations of a dovish Fed, growth worries and central bank policies putting more and more sovereign bonds into negative yields," Ole Hansen, the head of commodity strategy at Denmark's Saxo Bank A/S, wrote in an e-mail.

"The policies of the ECB and BOJ are already ultra-loose and further stimulus could be added following the Brexit vote."

A BOJ report on Monday revealed the nation's companies cut their forecasts for inflation for five years' time, adding to pressure on the central bank to boost stimulus.

Holdings in silver-backed exchange traded funds expanded to a record last month, and assets in gold ETFs are now at the highest since August 2013 as investors bet on a continued low-yield environment. Gold bullion rose 0.6% on Monday.

"Brexit has created all sorts of fear and loathing across markets," Commonwealth Bank of Australia analysts including Tobin Gorey, wrote in a note, adding that investors are cutting back on risk. "Gold and silver, as we would expect, benefit the most from safe-haven demand flows."

Brent crude slipped 0.5% to $50.10 a barrel. A militant group operating in Nigeria's southern oil-producing region said it attacked five crude-pumping facilities, dealing a blow to the government's effort to enforce a cease-fire.

Nickel, which is used in the production of stainless steel, rose 2.3% to more than $10,000 a ton in London.

Less than a third of miners operating in the nation are compliant with international standards for responsible mining, according to the government.

Frozen food maker BRF SA contributed the most to the index's gains.

Industrias Penoles SAB, the Mexican company that owns the world's largest silver mine, jumped 7.1%, bringing its gain this year to 179%. Mexico's IPC equity index closed the session little changed after a 4-day winning streak.

The MSCI Emerging Markets Index rose 0.5% to the highest since April. It is up 6.1% in five days, the best performance for the period since March 7.

Italy's FTSE MIB Index fell 1.7%, the biggest decline among western-European markets, as Banca Monte dei Paschi di Siena SpA and Banca Popolare dell'Emilia Romagna SC lost more than 6%. The ECB has asked Monte dei Paschi to draw up a plan for tackling its bad-loan burden, a sign the nation's banks are under pressure to bolster their finances.

The U.K.'s FTSE 100 Index lost 0.8%. The gauge of megacaps is close to entering a bull market, boosted by a weaker pound and a rally in miners of precious metals. Glencore PLC climbed 4.4% on Monday.

Japan's yen was little changed at 102.53 per dollar. It declined 0.3% last week as BOJ Governor Haruhiko Kuroda said more funds could be injected into the market should they be needed. The haven currency touched 99.02 in the wake of the vote for Brexit, its strongest level since 2014.

Brazil's real led losses among 31 major currencies and dropped 1% as the central bank intervened to weaken the currency.


The yield on Australia's 10-year government bonds increased by five basis points to 2%, after sinking to a record 1.95% in the last session. The nation's inconclusive vote raises the prospect Prime Minister Malcolm Turnbull's Liberal-National coalition -- or the main opposition Labor Party -- will be forced to work with a handful of disparate independent lawmakers in order to stay in power. Ballot counting doesn't resume until Tuesday.

"It looks like another three years of de facto minority government, which is not a great outcome for the economy and investment markets," said Shane Oliver, head of investment strategy at AMP Capital Investors Ltd., which manages more than $110 billion in Sydney.
