(Bloomberg) -- Former Federal Reserve Governor Laurence Meyer has a guess at where Chair Janet Yellen's interest rate forecast might be.

In what's become known as the "dot plot," Fed officials earlier this monthshowedthe public their best estimates for where the central bank's policy rate will be over the next few years. It's valuable information for investors who are desperate to know how quickly borrowing costs will rise in the U.S. What makes things tricky is that these dots are anonymous, and no one's views matter more than the chair's. 

Enter Meyer, who was a Fed governor from  1996 to 2002 and is now senior managing director at Macroeconomic Advisers. He's taken a stab at guessing which dots belong to whom. He estimates that Yellen in June foresaw a single rate hike this year. That would make her dot one of five at 0.375%, which is below the median of her fellow Federal Open Market Committee participants.

Meyer also expects her to change her view by September, by which point he expects to see an economy on stabler footing. 

Macroeconomic Advisers has assigned a policy maker to each dot. Some officials have already made public their views. The darker dots denote the median estimate among officials for each year. The median for 2015 was 0.625%, which would represent two hikes this year; and for 2016 it was 1.625%, representing four additional hikes.

SUFFICIENT MOMENTUM

After some disappointing numbers from the first half of this year, Yellen may have concluded that she needed more time between June and September to be comfortable "that the economy had regained sufficient momentum," he said.

That story is already changing, he said. Take this week's inflation data. The Fed has missed its inflation target of 2% for the personal consumption expenditures price index for three years mainly due to plunging fuel costs. Measures that eliminate prices that have shown extreme swings, such as the Dallas Fed's Trimmed Mean PCE, don't show much price acceleration either with annual rates bouncing around 1.6% for the past 14 months.

Meyer said the committee is looking at gauges of inflation over a shorter horizon to get a better reading on near-term price momentum as ``temporary factors restraining'' prices fade. Stripping away food and energy and measured on a three-month annualized rate,  so-called core PCE jumped higher to 1.6 in May, after rising 1.3% in April.

What's more, consumer spending rose last month by the most in almost six years, a report on Thursday showed. 

"We expect the incoming data between now and the September meeting to help ease concerns about the growth outlook, prompting Chair Yellen and a majority of the FOMC to see two hikes this year as appropriate," Meyer said in a note to clients.
