Stocks climbed on Tuesday as oil prices fell and the Federal Reserve began its two-day meeting to determine the direction of interest rates.

US monetary policy has been key a focus over the last several weeks as other central banks around the world have lowered interest rates to stave-off slowing growth. The Fed is expected to follow suit and cut borrowing costs by 25 basis points in September.

Oil plunged on Tuesday after Reuters reported Saudi Arabia's output is expected to recover in two to three weeks. Saudi Arabia is also close to restoring 70% of its daily production of 5.7 million barrels cut by an attack on key facilities over the weekend. The drop in prices parred some of oil's historic price gain on Monday.
