Fresh problems for “Obamacare”: The largest health insurer in Texas wants to raise its rates on individual policies by an average of nearly 60 percent, a new sign that President Barack Obama’s overhaul hasn’t solved the problem of price spikes.

That’s to account for lower-than-hoped enrollment, sicker-than-expected customers and problems with the government’s financial backstop for insurance markets.

The national picture will take weeks to fill in. With data available for about half the states, premium increases appear to be sharper, but there are also huge differences between states and among insurers. Health insurance is priced locally.
