As the initial U.S.-Iran accord pulled crude toward $70 a barrel, global stocks staged a relief rally, market reports said. The KOSPI and other major Asian markets rebounded together, lifted by returning risk appetite.

Falling oil eases corporate cost burdens and inflation worries, working in stocks' favor, an especially direct boon for energy-importing Asian economies.

Still, the recent sharp swings show the scale of volatility. In a market that lurches in the short term with geopolitical events, overconfidence in one direction is dangerous.

Investors are watching the deal's durability, exchange rates and interest-rate trends together. Whether the relief rally becomes a sustained rise depends on stability in diplomacy and macro variables.

Sinophone Bridge Times reports the market's cheer as fact while noting it does not equal safety. In a volatile market, the responsibility for investment decisions always rests with the individual.
