June 15 (Reuters) - Wall Street's main indexes rose on Monday, with the Dow Jones hitting a record high, after the United States and Iran reached a tentative agreement to end the war in the Middle East and reopen the Strait of Hormuz, easing inflation fears as crude oil prices fell.

The framework agreement — which is expected to be formally signed in Switzerland on Friday — did not address key issues such as Tehran’s nuclear program and the conflict between Israel and Lebanon.

Shares of interest-rate-sensitive technology companies rose as investors became more comfortable taking risks with lower oil prices and easing inflation fears.

Gene Goldman, chief investment officer at Citerra Investment Management in California, said, "Markets are rising in a classic relief-driven rally. We have a deal between the US and Iran that is leading to a sharp drop in oil prices. This is easing inflation fears and essentially driving investors back into riskier assets like technology."

According to preliminary data, the S&P 500 rose 123.80 points, or 1.67 percent, to close at 7,555.26 , while the Nasdaq Composite climbed 797.79 points, or 3.07 percent, to 26,686.64. The Dow Jones Industrial Average gained 490.38 points, or 0.96 percent, to 51,684.88 .
