• GBP/USD turns lower for the third straight day amid a modest USD uptick.
• The cautious market mood is seen benefitting the safe-haven Greenback.
• Bets for an imminent Fed rate hike pause might continue to cap the buck.

The GBP/USD pair struggles to capitalize on the previous day's goodish rebound of over 70 pips and attracts fresh sellers near the 1.2455-1.2460 region, or the 50-day Simple Moving Average (SMA), on Tuesday. Spot prices turn lower for the third straight day and trade just above the 1.2400 round-figure mark during the first half of the European session.

The prevalent cautious mood around the equity markets lends some support to the safe-haven US Dollar (USD), which, in turn, is seen as a key factor acting as a headwind for the GBP/USD pair. That said, any meaningful upside for the USD seems elusive amid rising bets for an eventual pause in the Federal Reserve's (Fed) policy tightening cycle. In fact, the current market pricing points to a greater chance that the US central bank will leave interest rates unchanged next week.

It is worth recalling that a slew of influential Fed officials last week backed the case for skipping an interest rate hike at the June policy meeting. Adding to this, the disappointing release of the US ISM Services PMI on Monday, which fell to 50.3 in May, signals more cooling in the US economy and offers lesser headroom for the US central bank to keep raising interest rates. This leads to a further decline in the US Treasury bond yields and acts as a headwind for the Greenback.

Apart from this, expectations that the Bank of England (BoE) will be far more aggressive in policy tightening to contain stubbornly high inflation might further contribute to limiting the downside for the GBP/USD pair. This, in turn, suggests that any subsequent decline might still be seen as a buying opportunity and remain limited. In the absence of any relevant market-moving economic releases from the US, the USD price dynamics will continue to play a key role in influencing the major
