user: Problem: The ruling Fidesz party, which has a two-thirds majority, has approved the constitutional change in the final session of parliament this year.
Ratings agency Standard & Poor's downgraded Hungary's debt to junk status last week, partly due to the proposed changes to the constitution.
EU and IMF officials have cut short aid talks with Hungary over to the law.
Hungary had been seeking a standby credit line of 15-20bn euros ($19.5bn, Â£12.6bn) in case it ran into trouble issuing new debt.
But the International Monetary Fund and the European Commission have both cast doubts over aid because of the law.
On Thursday, Hungary abandoned part of a planned bond auction, when investors demanded a higher interest rate on the debt the country planned to issue.
Hungary's central bank governor, Andras Simor, has said the bill amounts to a takeover of the central bank.
The law has also been criticised by the European Central Bank, who said it raised "concern as to whether [it] could be used to influence the decision-making process, to the detriment of central bank independence".
International pressure
The government wants to keep interest rates low to boost growth - but last week, Hungary's central bank increased rates for the the second month in a row, to 7% from 6.5%.
Consumer prices inflation in Hungary is currently running at 4.25%, well above the official 3% target.
"Some amendments have been made since the original draft was presented before the Christmas holiday, but concerns remain that the essence of the law has not changed," said the BBC's Eastern Europe reporter Nick Thorpe.
"The reform of the bank would introduce deputy governors and allow the government greater potential influence over key aspects of monetary policy, such as the level of interest rates."
Hungary was given a 20bn-euro standby loan by the IMF in 2008 to prevent it having to default on its debts.
But the newly-elected Prime Minister Viktor Orban decided not to renew the standby facility last year.
Standard & Poor's has cited heightened risks to the country's ability to repay its debts due to the weakening domestic and global economic outlook.
"In our view, the predictability of Hungary's policy framework continues to weaken, harming Hungary's medium-term growth prospects," S&P said.
Last month, fellow ratings agency Moody's also downgraded Hungary to junk status, blaming the economy's high levels of debt and weak prospects for growth.

Blossoms singer and guitarist Tom is a former Manchester City season ticket holder, who grew up idolising former striker Paul Dickov.
"I wrote his name on the back of my City shirt in black marker," Ogden told BBC Sport. My mum wasn't too happy about that.
"I don't miss those days when we were struggling, though. You want to be winning the league, don't you? Dickov is still my hero because he was playing for us when I first got into football but Sergio Aguero is the man.
"Obviously there is a charm in being everyone's second favourite team when you are in Division One but I much prefer to be where we are now, with Pep Guardiola as manager and having won the title twice in the past four years."
Bass player Charlie supports his home town team despite County's drop into non-league football, but also follows Liverpool.
"I'm biased but I'd love to see us win the league," he explained. "That's not just because I am a fan but for Jurgen Klopp's sake - I think he is such a character, he is good for the game."
A correct result (picking a win, draw or defeat) is worth 10 points. The exact score earns 40 points.
