LONDON, Jan 22 (Reuters) - Oil fell under $76 on Friday as commodities across the board remained under pressure from U.S. President Barack Obama's proposed reform of banks' trading. [
] [ ]Obama's proposals to cut proprietary trading raised the possibility of banks and funds looking again at their involvement in the commodities sector, where they have boosted their presence heavily. [
] [ ]U.S. crude <CLc1> was 65 cents down at $75.43 a barrel at 1400 GMT. ICE Brent crude <LCOc1> fell 52 cents to $74.06.
The full implications of Obama's proposals had yet to play out, analysts said.
"The potential consequences are huge, and the continued strength and liquidity of markets will depend on how effectively the banks and their employees are able to to reorganise and adjust to the new regime, if and when it comes into force," said leading oil brokerage PVM in a note.
"If you're an oil trader working for a bank, Obama's plan is not going to help your career."
Oil prices rose to 15-month highs near $84 a barrel in early January, partly due to an influx of money following a hike in fund allocations. [
]"Potentially, some funds will need to revise their exposure for the second half of the year," said Petromatrix analyst Olivier Jakob, referring to both Obama's plan and the package of proposals unveiled last week by the U.S. futures regulator, the Commodity Futures Trading Commission.
"For now, it will weigh on sentiment in a global sense," said Jakob.

FALLING INVENTORY
A fall in inventory levels in the world's biggest oil consumer, shown in data released on Thursday, supported prices
U.S. crude stocks fell by by 400,000 barrels last week and distillates, including heating oil, also fell by a more than expected amount according to the Energy Information Administration, raising hopes about the pace of demand recovery in the world's largest energy consumer. [
]The dollar fell broadly against other currencies and this also helped boost oil prices. A weak dollar tends to support oil as it makes it cheaper for non-dollar buyers. [
]Analysts said that $75 a barrel was likely to remain a key support level, defining the bottom of the current $75-$80 trading range.
"In the rally, speculators added length. $75 a barrel needs to hold and if it doesn't, there could be further liquidation of positions and further falls," said Jakob.
Concerns that oil-consuming nations could take steps to temper growth may also weigh on prices going forward, analysts said. The world's number two oil consumer China reported fourth quarter growth of 10.7 percent on Thursday, its first double digit figure since 2008. [
]"Any efforts by the Chinese government to slow the economy would affect demand for raw materials," said Serene Lim, a Singapore-based oil analyst at ANZ.
