GBP/USD Forecast: Downtrend resistance and Powell may put an end to the recovery

• GBP/USD has been rising from the lows amid mixed data.
• Fed Chair Powell's testimony is left, right, and center.
• Wednesday's four-hour chart shows pound/dollar is attempting to break downtrend resistance.

GBP/USD has barely escaped the abyss of reaching the lowest in over two years – but no dangers await. Tuesday's mix of worries around Brexit sent cable to 1.2439 – only one pip above the 2019 low of 1.2438 recorded in January. A fall to 1.2437 would have represented the lowest levels since 2017. 

Today's data has already provided an excuse for a much-needed recovery. May's GDP read came out at 0.3% – as expected – and that was enough to spark a run higher. Manufacturing production has fallen marginally short of expectations with an increase of 1.4%. 

Boris Johnson and Jeremy Hunt – which are vying to become Prime Minister – have clashed on a television debate. Johnson stressed the importance of leaving by the October 31st deadline and opened the door to bypassing parliament. In the meantime, the House of Commons narrowly voted in favor of a bill that would prevent the government from overriding parliament – the battle is far from over. 

Johnson refused to commit he would quit if that did not happen The former foreign minister continues leading the polls and will likely enter 10 Downing Street by the end of July.

The focus now shifts to the Fed. Jerome Powell, Chair of the Federal Reserve, will testify on Capitol Hill and is set to shed light on future monetary policy. Markets currently expect Powell to confirm a one-time rate cut. If he refrains from such a commitment – defying President Donald Trump's wishes – the greenback would soar. If he expresses concern about subdued inflation and global growth – opening the door a series of rate cuts – the greenback could fall.

GBP/USD Technical Analysis

Pound/dollar is capped by downtrend resistance which has been formed in late June. It has touched the price four times, making it significant. The pair is trying to break above it at the time of writing. 

The Relative Strength Index (RSI) on the four-hour chart has risen above 30 – shrugging off oversold conditions – and opening the door to fresh falls. 

Initial support awaits at 1.2480 which was Friday's low. The weekly low of 1.2439 – which may turn into a long-term double bottom if it is not broken soon – is critical support. The next lines date back to 2017 and they include 1.2360, 1.2305, and 1.2100.

Resistance awaits at 1.2505 which was June's low, followed by 1.2560 which was the trough in late May, and then by 1.2605 worked as both support and resistance in recent months.
