Global Stock Performance Amid Oil Price Surge

NEW YORK, March 19 (Reuters) - Global stocks slumped on Thursday as oil prices spiked after the latest escalation in the U.S. and Israel's war with Iran, while a host of major central banks left interest rates unchanged as they attempt to assess rising price pressure.

Crude Oil Volatility and Inflation Concerns

Brent crude prices shot above $119 a barrel and further fanned inflation fears following attacks on Iran's South Pars gas field, along with the world's largest gas plant in Qatar as well as on oil refineries in both Saudi Arabia and Kuwait.

Trading in oil futures was volatile, and U.S. crude settled down 0.19% to $96.14 a barrel while Brent settled at $108.65 per barrel, up 1.18%. The session high for Brent above $119 was the second time it crossed that threshold this month. Prices eased as the Trump administration took steps to try to expand supply and after comments from Israeli Prime Minister Benjamin Netanyahu.

Wall Street and Global Indices Reaction

On Wall Street, U.S. stocks closed lower. Earlier declines in the small-cap Russell 2000 index briefly brought the index down more than 10% from its January 22 record closing high. The benchmark S&P 500 index closed below its 200-day moving average for the first time since May 9.

The 20-day daily correlation for the S&P 500 to both Brent and WTI crude is the most negative it has been since November 2004.

Investor Sentiment and Market Commentary

"It's been fairly binary in terms of when oil's rising and inflation and inflation expectations are rising, it's risk off, and when there's something out there to kind of stabilize oil prices, we tend to get a little bit of a rally," said Michael Arone, chief investment strategist at State Street Investment Management in Boston.

"What this suggests is that investors and capital market participants are still bought into the idea that this is a short-duration war with a resolution in sight in the next couple of months, and anything to refute that causes some challenges."

Major Index Performance

The Dow Jones Industrial Average fell 203.72 points, or 0.44%, to 46,021.43, the S&P 500 shed 18.21 points, or 0.27%, to 6,606.49 and the Nasdaq Composite lost 61.73 points, or 0.28%, to 22,090.69.

MSCI's gauge of stocks across the globe fell 8.84 points, or 0.88%, to 996.62 while the pan-European STOXX 600 index fell 2.39%, its biggest daily percentage drop since March 3 as the index closed at its lowest level in three months.

Central Bank Responses and Bond Market Movements

Benchmark government bond yields, which set the global cost of borrowing, also climbed as multiple central banks kept rates unchanged while assessing economic fallout from the surge in crude prices.

Bank of England and UK Market Impact

The Bank of England's rate setters voted unanimously to keep UK rates on hold and said they were "ready to act" to stave off risks from war in the Middle East.

The yield on two-year gilts surged 29.8 basis points to 4.404% after earlier touching a 14-month high of 4.486%, although Bank of England Governor Andrew Bailey said financial markets were getting ahead of themselves in expecting interest rate rises. Sterling strengthened 1.35% to $1.3432 against the dollar.

European and Global Central Bank Actions

The European Central Bank held its rates as well, warning that the Iran war was clouding the outlook for growth and inflation. The Bank of Japan and the U.S. Federal Reserve had both voiced their concerns about the conflict during their earlier policy statements, which left their respective rates unchanged.

The yield on benchmark U.S. 10-year notes edged up 0.4 basis point to 4.261% while the 2-year note yield, which typically moves in step with interest rate expectations for the Fed, climbed 5.6 basis points to 3.799 after hitting 3.96%. The two-year yield has shot up 42 basis points in March.

Other Central Bank Moves

Earlier this week, the Reserve Bank of Australia hiked rates to a 10-month high and warned of a "material" risk to inflation from the oil price spike.

Switzerland's central bank kept its rates at zero, and signaled it was ready to intervene to curb the recent surge in the Swiss franc, one of the traditional safe havens in volatile markets.

Currency Markets and Central Bank Policy Statements

The dollar index, which measures the greenback against a basket of currencies, dropped 1.01% to 99.19, with the euro up 1.19% at $1.1586.

Japanese Yen and Bank of Japan Policy

Against the Japanese yen, the dollar weakened 1.41% to 157.61 but remained near the key 160 per dollar level following the BOJ's policy statement, leaving investors on watch for possible FX intervention after strong comments from Japanese Finance Minister Satsuki Katayama earlier in the day.

The Bank of Japan had left its short-term policy rate at 0.75% as widely expected overnight, but it joined the U.S. Federal Reserve and Bank of Canada in striking a cautious tone about the war and pricing pressures.
