The ringgit extended last week's gains, opening stronger against the US dollar and a basket of major currencies, supported by a weaker US Dollar Index (DXY) amid expectations that tax cuts and spending are being discussed in the US Senate.
At 9.50am, the ringgit was at 4.2180, up 0.19% against the US dollar from its close of 4.2300 at last week's close.
The US DXY is currently hovering at 97.151 points, down 0.26% from its previous close.
Bank Muamalat Malaysia Bhd chief economist Dr Afzanizam Rashid said the US Senate is currently considering passing tax cuts, reducing Medicaid spending and lowering clean energy subsidies.
The decision is set to increase the US government's fiscal deficit and debt levels, with the Congressional Budget Office (CBO) projecting the bill will increase the deficit by nearly $3.3 trillion from 2025 to 2034, while 11.8 million Americans will be uninsured by 2034.
Afzanizam said the US government's credit matrix will weaken, which could add to pressure on the value of the US dollar.
