Do deficits matter? The federal government is spending wildly these days, but until recently, many economists argued that a glut of savings would easily cover the cost by keeping interest rates low. The Congressional Budget Office outlook issued in February predicted that despite the debt explosion, the government’s outlays in interest would actually decline in the next several years, thanks to low rates.

No more. A new estimate out last week updates the February forecast, and predicts higher interest rates. It also shows how sensitive debt service is to interest rate levels: debt service projected for 2026 jumped to $467 billion, up by $106 billion from the February projection.

Fortune’s Shawn Tully says even that estimate is too optimistic. The CBO, he argues, is underestimating both likely spending and the path of interest rates, putting the “U.S. on a treadmill to catastrophe.” You can read his analysis here.

Is he right? The super low rates of the last decade have given analysts some reason to believe we are in a new era of ample capital and perpetually low rates. But new eras eventually come to an end. This one bears watching.

The substantial ransomware attack that took place Friday only caused "minimal damage" to American businesses, President Biden said yesterday. A Russia-linked syndicate called REvil has claimed responsibility and demanded $70 million for the restoration of victims' data.

Ever Given

The Ever Given—the gigantic container vessel that caused global chaos when it got stuck in the Suez Canal for six days in March—is finally set to leave the waterway. It was effectively impounded after that incident, as the Suez Canal Authority wanted over $900 million in compensation. The authority and the ship's owners and insurers have now reached a settlement, reported to total $550 million. A particularly hearty congratulations to the crew, who have been stuck there for more than three months. Fortune

Social surveillance

The European Parliament has approved a bill that will temporarily let social-media companies scan their platforms for child sexual abuse material—and, crucially, private messages that may indicate grooming—without worrying that they are breaking the EU's privacy laws. The law is controversial, with privacy-minded lawmakers saying it threatens encrypted communications, and warning that it won’t survive court challenges. Politico
