* Bank's apparent caution follows volatility in commodities (Updates with JPM VaR details, commodity market moves in Q2, background of bank's push into commodities and peer risk comparison table)

July 13 (Reuters) - JPMorgan Chase & Co's commodities trading risk fell to its lowest level in two years during the second quarter as tumbling prices sidelined many investors in oil, metals and agricultural markets, company results showed on Friday.
The largest U.S. bank by assets said its value-at-Risk (VaR) in commodities fell by 38 percent to average $13 million per day in the three months to June, versus $21 million in the first quarter.
VaR is an industry term for the maximum money a financial institution is willing to lose a day for trading a particular asset class. It is an important consideration when firms make trading or hedging decisions.
In the case of Wall Street banks, such as JPMorgan, that typically do not break down their commodity earnings, VaR is often the only guide of their exposure in that area.
Of the four asset classes that define JPMorgan's VaR, commodities was the only group that showed such a decline. The VaR for equities jumped 18 percent from the first quarter; the reading for fixed income rose 10 percent, while the risk for foreign exchange was barely changed.
The last time JPMorgan's commodities VaR averaged $13 million was in the first quarter of 2010.
Compared to the first quarter of this year, its commodities risk was lower too by an average of $3 million.
A relative late comer to commodities trading compared to established peers such as Goldman Sachs and Morgan Stanley, JPMorgan achieved record revenues above $2.8 billion in the business last year, propelling it above its archrivals.
It made its push towards the sector in 2010 as Wall Street banks started winding down risky proprietary trading desks to comply with new U.S. financial laws. Many have stayed on in the business by servicing client orders.
JPMorgan's apparent caution towards commodities came after unexpected twists and turns in oil, metals and agricultural markets over the past three months.
After a relatively mild April, commodity prices tumbled their most in nine months in May and continued a broad downtrend until a violent snap back on the last trading day of June.
The 1 percent drop on the benchmark Thomson Reuters-Jefferies commodities index in April -- followed by an 11 percent slump and 4 percent gain in subsequent months -- tripped up some of the biggest speculators in the sector, including hedge funds which posted sharp losses.
The whipsaw volatility also sent many investors scurrying to the relative safety of U.S. Treasuries and the dollar.
"The volatility in commodities has obviously taken a toll across the board on banks involved in those markets," said Peter Cardillo, chief market economist at Rockwell Global Capital in New York.
JPMorgan's trading division faced a particularly difficult second quarter for another reason: wrong credit bets that caused it to lose nearly $6 billion and brought unwanted regulatory scrutiny to the bank.
Usually the first major U.S. bank to report earnings in a quarter, JPMorgan said it managed to earn a net income of $4.96 billion in the second quarter versus $5.43 billion a year ago, in spite of its disastrous credit positions.
