Asian foreign exchange markets are currently being shaped by contrasting central bank trajectories, which are directly influencing the valuation and momentum of regional currencies. The Bank of Thailand (BoT) is widely expected to keep the policy rate steady at 1.00% for a third straight meeting on Wednesday. Persistent negative real interest rates are anticipated to keep THB positioned as an Asian FX laggard.

 

## Policy Adjustments in South Korea and the Philippines

In contrast, the Bank of Korea (BoK) is anticipated to implement a back-to-back 25bps rate hike, bringing its benchmark to 3.00% on Thursday. While a minority of analysts polled by Bloomberg, specifically 5 out of 17, projected no change in rates, the broader consensus expects tighter monetary policy, a move that could potentially offer the South Korean won additional macroeconomic support.

Similarly, the Philippine central bank (BSP) is projected to deliver a third consecutive 25bps hike, lifting its policy rate to 5.00% on Thursday. A minority of analysts surveyed by Bloomberg, 4 out of 22, penciled in a pause, but expectations remain high that the central bank will raise borrowing costs to curtail ongoing weakness in the peso. Last week, USD/PHP rallied to a record high near 62.00, a movement underpinned in part by firmer crude oil prices.

 

## Movements in Global Currencies and the US Dollar

Beyond Asia, major currency pairs are experiencing notable adjustments at the start of the week. GBP/USD has pulled back from its recent recovery efforts, revisiting the lower 1.3600s. Cable is trading with a mild downward bias amidst decent gains in the Greenback, as market participants remain highly cautious ahead of upcoming US economic data releases and the Jackson Hole symposium.

Similarly, EUR/USD is trading on the defensive following Wall Street's closing bell, hovering around the 1.1660 region to extend Friday's modest pullback. This downward pressure comes in response to an acceptable rebound in the US Dollar, driven by generalised caution ahead of crucial US macroeconomic reports and Chair Warsh’s scheduled speech in Jackson Hole.

 

## Precious Metals and US Treasury Buyback Expansion

Gold has surrendered a portion of its initial advance, yet the precious metal maintains its resilient bullish pace firmly above the $4,600 per troy ounce threshold. This upward trajectory persists despite slight gains in the US Dollar and a modest retreat in US Treasury yields across the curve.

Meanwhile, the US Treasury implemented a notable adjustment to its operational calendar on Wednesday. At 12:32 GMT, the department announced it would at least double the size of liquidity support buyback operations targeting the 10-year to 20-year and 20-year to 30-year sectors. This policy lifts the maximum operational limit from $2 billion per operation to at least $4 billion, effective from September 9 through November 4.
