Asian currencies were rangebound against the dollar, but U.S. federal debt topping $40 trillion may provide support, Commonwealth Bank of Australia (CBA) global economics and markets research said. CBA warned concerns over U.S. debt sustainability could pressure the dollar this week after Treasury Secretary Bessent’s remarks raised expectations for a budget consolidation plan; if consolidation is limited, market disappointment could weaken the dollar. USD/JPY ~158.9, AUD/USD 0.7166.
