ASX 200 utilities shares led the market sectors last week, rising 3.34% over the five trading days.

Meanwhile, the S&P/ASX 200 Index (ASX: XJO) lost 0.27% to finish at 8,580.1 points on Friday.

The utilities sector's bump was a substantial outperformance, with its nearest competitor, ASX 200 materials, up just 0.8%.

This may indicate a shift to defensive shares, given that the utilities sector is known for stable returns and dividends.

Utilities delivered the highest dividends of all 11 market sectors in FY25 at 6.17%.

Last week, US President Donald Trump extended the 90-day reprieve on the full range of US reciprocal tariffs to 1 August.

Trump also stated that a new tariff on imported pharmaceuticals into the US from next year may be set as high as 200%.

This impacted several ASX pharma stocks, including Australia's biggest listed healthcare company, CSL Ltd (ASX: CSL).

The market was also surprised last week when the Reserve Bank of Australia decided to keep interest rates on hold.

The board members were split 6:3, with six voting for rates to stay on hold pending quarterly inflation data due out on 30 July.

Three board members voted for a rate cut.

In a statement, the RBA said:

With the cash rate 50 basis points lower than five months ago and wider economic conditions evolving broadly as expected, the Board judged that it could wait for a little more information to confirm that inflation remains on track to reach 2.5 per cent on a sustainable basis

The next board meeting to discuss interest rates is scheduled for 11-12 August.

Only five of the 11 ASX 200 market sectors closed out last week in the green.

Let's recap.
