NAIROBI, Feb 20 (Reuters) - The International Monetary Fund stopped Kenya's access to a $1.5 billion standby credit facility last June after failing to agree with the government on a reduction of the fiscal deficit, the fund said on Tuesday.
The two-year precautionary facility, set to expire next month, was put in place for Kenya in case of unforeseen external shocks that could put pressure on the balance of payments.
The East African economy has not tapped the facility, which was preceded by a smaller standby one-year credit line in 2015, as foreign exchange reserves held by the central bank have soared to record highs.
"The programme has not been discontinued but access was lost in mid-June because a review had not been completed," Jan Mikkelsen, IMF representative in Kenya, told Reuters.
"There was no agreement on the fiscal adjustment at the time and then I do believe the lengthy election period (later in the year) made it difficult to have a review and complete that in the period that followed."
The government did not respond to requests by Reuters for comment. It has published a plan to lower the deficit to 7 percent of GDP at the end of this fiscal year in June, from 8.9 percent in 2016/17, and to less than 5 percent in three years' time.
Mikkelsen said a team from the fund's Washington headquarters was in the country for talks on a Kenyan request for a new standby credit facility. He did not comment on the government's fiscal deficit reduction plan.
"We have just started discussions," he said. "I'm hopeful we will get an agreement."
The fund wanted to see "substantial fiscal consolidation" to lower the deficit and put the country's debt onto a "sustainable path".
Kenya's total debt has risen to about 50 percent of GDP, from 42 percent in 2013, as it borrowed locally and abroad to build infrastructure like a new railway line from Nairobi to the port of Mombasa.
At the time it secured the precautionary facility from the IMF, officials at the fund said it was a triumph of Kenya's stable economic fundamentals, because that type of facility is usually reserved for more developed emerging economies.
But investor worries have grown due to the gaping fiscal deficit and sluggish private sector credit growth, after the government capped lending rates at 14 percent in 2016.
"The interest rate controls should either be eliminated or significantly modified to allow banks to price risks properly and thereby promote an increase in credit to the private sector," Mikkelsen said.
He said a reduction of the fiscal deficit and the elimination of the cap on commercial lending rates were key to a new agreement between the fund and Kenya. (Editing by Andrew Roche)
