Asian stocks pared gains and crude oil advanced after reports of US strikes on sites in Iran damped optimism over a potential deal with Tehran.
The MSCI Asia Pacific Index pared most of an earlier gain to edge up 0.1%, after climbing as much as 0.4% earlier Tuesday. US equity-index futures rose 0.6%, though gains were more muted than Monday’s holiday-thinned advance, when markets in the US were closed. Treasuries rallied across the curve as cash trading resumed after a holiday break.
