June 29 (Reuters) - Emerging-market stocks edged higher on

Monday while currencies held broadly steady, as investors

weighed a brief flare-up in Middle East tensions against

lingering doubts over a fragile ceasefire in the region.

The MSCI emerging-market equities index rose 0.2%,

while its currency counterpart was little

changed.

A pause in the latest exchange of attacks in the Middle East

offered some relief to markets. But the mood remained fragile,

with investors also weighing stretched technology valuations, a

stronger dollar and the prospect that resilient U.S. growth

could keep Federal Reserve rates elevated for longer.

Oil prices, which have surrendered nearly all their gains

since the U.S.-Israeli conflict with Iran flared in late

February, initially rose on renewed hostilities before easing as

prospects for fresh talks raised hopes of salvaging an interim

deal.

That helped steady sentiment in oil-sensitive emerging

markets, though Asian equities remained under pressure as the

region's high-flying technology shares continued to retreat.

"As we move into Q3, the focus is already turning to

shifting geopolitics, a strong U.S. economy, the potential for

fresh Federal Reserve rate hikes, and a selloff in tech stocks

that is particularly acute in Asia," said Kathleen Brooks,

research director at XTB.

South Korea's KOSPI, a bellwether for the

artificial-intelligence trade, fell as much as 3.4% after losing

7% last week, before paring losses to close 0.2% lower.

On the other hand, Taiwan stocks gained 1%. The

index is up 56% this year, making it the region's second-best

performer behind the KOSPI's 97% rally.

Those outsized gains in South Korea and Taiwan have powered

the broader MSCI emerging-market equities index, leaving it on

track for its strongest quarter since 2009.

In central Europe, Serbian assets were in focus after

thousands of protesters gathered in Kraljevo on Sunday,

maintaining pressure on President Aleksandar Vucic a day after

he said he would step down within weeks to allow early

presidential and parliamentary elections.

Although many protesters welcomed Vucic's planned

resignation, some fear he may try to retain influence behind the

scenes. Serbia's dinar was flat against the euro.

Elsewhere in emerging Europe, currencies weakened against

the euro but were broadly steady versus the dollar. Regional

shares edged lower, with Hungary's benchmark down 0.6%,

while the forint slipped 0.2%.

Hungary's 2026 budget deficit could exceed 7% of economic

output even if the country secures billions of euros in European

Union funding, Prime Minister Peter Magyar said.

Turkish stocks fell 0.3%, while the lira

was steady.

In South Africa, the rand edged 0.2% lower as gold, a key

export, eased, while Johannesburg's main share index

rose 0.9%.

Meanwhile in other EMs, Bolivia will adopt a flexible

exchange-rate system, the government said on Friday, effectively

devaluing the currency by ending a 15-year dollar peg in a major

policy shift aimed at restoring economic stability.
