NEW YORK/LONDON, April 24 (Reuters) - The dollar dipped

on Friday but remained on pace for a weekly gain as traders

continued to assess the prospects for a resolution to the

U.S.-Israeli war with Iran.

The currency has been buoyed at times by optimism that a

near-term deal could end the conflict, then weighed down by

fears that a prolonged war will trigger lasting energy

disruptions. With the outcome still uncertain, many traders are

reluctant to take on large positions, keeping the market largely

range-bound.

"Right now you really can't have anything on the table

because you don't know where this is going," said Lou Brien,

strategist at DRW Trading in Chicago.

"Unless there's some big news like they just all declare

peace and go home, I think the next real move on the markets is

going to be a reaction to real things, such as shortages of

crude oil affecting economic performance in Europe or Asia," he

said.

Iran's Foreign Minister Abbas Araqchi was expected in

Islamabad on Friday, venue for past peace talks with the United

States, raising hope that negotiations could resume after they

collapsed earlier this week.

The dollar index, which measures the greenback

against a basket of currencies including the yen and the euro,

fell 0.11% to 98.71, with the euro up 0.14% at $1.1699.

The dollar index is heading for a weekly 0.50% gain, with the

euro on track for a 0.53% weekly loss.

The Japanese yen strengthened 0.05% against the

greenback to 159.62 per dollar. Sterling

strengthened 0.16% to $1.3488.

"If you look at the last week, the major theme is just that

there's no real progression with peace talks. For markets, it's

difficult when there's no deadline," said Tommy Von Brömsen, FX

strategist at Handelsbanken in Stockholm.

CENTRAL BANK BONANZA LOOMS

Traders are also looking ahead to a busy week for central

banks, with the Federal Reserve, the Bank of Japan, the European

Central Bank, and the Bank of England among those set to

announce policy decisions.

"The main message from the central banks is that they are -

so far at least - in a kind of 'wait-and-see' approach,"

Handelsbanken's Von Brömsen said.

Fed funds futures traders are pricing in just a 23% chance

of a Fed interest rate cut this year, reflecting concerns about

a renewed bout of inflation.

The European Central Bank is expected to hold its deposit

rate on April 30, but just over half of economists polled by

Reuters forecast a hike in June, as policymakers look to shield

the euro zone economy from a war-induced energy shock.

The Bank of England meets on Thursday. Money markets are

pricing in a rate hike by year-end, though no change is expected

at next week's meeting.

In Japan, core consumer inflation slowed below the Bank of

Japan's 2% target for a second consecutive month in March.

Analysts expect price pressures to pick back up in the coming

months as companies begin passing on higher fuel costs stemming

from the Middle East conflict.

The BOJ is set to conclude its two-day policy meeting on

Tuesday and is widely expected to hold interest rates steady, as

fading prospects for a near-term end to the war keep Japan's

economic and price outlook highly uncertain. That said, the

central bank is still expected to signal its readiness to

tighten policy to counter mounting inflationary pressures.

Japanese Finance Minister Satsuki Katayama on Friday

reiterated her verbal warning on intervention, saying

authorities stand ready to take "decisive" action against

speculative moves in the foreign exchange market. Her comments

came a day after she said Japan has a "free hand" to intervene

and that past interventions had been effective.
