* Yen jumps on falling Japanese stimulus expectations

* Oil dips on oversupply worries; U.S. crude hits April lows

LONDON, July 26 (Reuters) - A buoyant yen and oil prices at their lowest in three months kept stock markets on the defensive on Tuesday as investors awaited central bank meetings this week that will unveil new stimulus in Japan and may provide clues on U.S. interest rates.

U.S. equity markets fell while stocks in Europe traded slightly above break-even as gains in major healthcare and consumer goods stocks propped up European equities to offset persistent concerns over the region's banking system.

The yen hit two-week highs against the euro and more than one-week highs against the dollar as traders dialed back expectations of how much new stimulus authorities will inject into Japan's ailing economy at the end of the week.

Most economists surveyed by Reuters expect the Bank of Japan to expand its asset purchases and cut rates further below zero at a two-day meeting that ends on Friday.

Comments by Japan's finance minister, Taro Aso, raised concerns that the government will not work as closely with the BOJ to implement new stimulus as investors had hoped.

"We are also seeing not much pressure from the Japanese government on the BOJ to ease. All this is helping the yen," said Yujiro Goto, currency strategist at Nomura.

The yen gained 1.09 percent against the dollar to 104.61. The euro fell 1.37 percent to 114.91 yen.

MSCI (NYSE: MSCI - news) 's all-country world stock index traded near break-even, while the pan-European FTSEurofirst 300 index rose 0.2 percent to close at a provisional 1,348.04.

The Dow Jones industrial average fell 73.66 points, or 0.4 percent, to 18,419.4. The S&P 500 slid 4.59 points, or 0.21 percent, to 2,163.89 and the Nasdaq Composite lost 2.48 points, or 0.05 percent, to 5,095.15.

The U.S. Federal Reserve is expected to leave interest rates unchanged when it concludes its two-day meeting on Wednesday. Investors are looking for any signs that the U.S. central bank might be more likely to hike rates in coming months.

Data showed U.S. consumer confidence holding steady in July while new single-family home sales hit their highest level in nearly 8-1/2 years in June, suggesting sustained momentum in the economy.

Other data showed moderate gains in house prices in May, which should support consumer spending and keep home purchasing affordable, especially for first-time buyers who have started venturing into the housing market.

The U.S. central bank is widely expected to leave its target on policy rates at 0.25 percent to 0.50 percent this week due to global risks, but traders seemed wary of signals the Fed would consider raising rates by year-end on signs the economic expansion remains on track.

U.S. Treasury yields rose, reversing an early decline on European government debt, with yields stuck in negative territory due to purchases by the European Central Bank.

The benchmark 10-year Treasury yield was up 1 basis point at 1.5748 percent.

U.S. crude was down 12 cents at $43.01 a barrel.

Brent rose 12 cents to $44.84 a barrel.
